Background Conversion from sorafenib to regorafenib is primarily an evidence-based treatment strategy in patients with advanced hepatocellular carcinoma (HCC). This study aimed to assess the safety and efficacy of sequential therapy with sorafenib and regorafenib in patients with advanced HCC by analysis of outcomes in clinical practice with the aim to complement phase III findings. Methods The medical records of patients with advanced HCC receiving regorafenib were retrieved to collect data on sorafenib administration at seven Japanese institutions. Radiological responses and adverse events were evaluated using the Response Evaluation Criteria in Solid Tumors version 1.1 and the Common Terminology Criteria for Adverse Events version 4.0, respectively. Results Before March 2018, 44 patients were administered regorafenib for advanced HCC. The median sorafenib treatment duration was 8.4 months. The most common adverse events were similar to those reported by the RESORCE trial. The median overall survival (OS) was 17.3 months (95% confidence interval [CI] 11.4-22.9), and 17 of 37 patients (45.9%) discontinued regorafenib and received sequential systemic therapy after regorafenib. These patients had significantly longer OS than those who were treated by the best supportive care or sub-optimal therapy (not reached versus 8.7 months [95% CI 5.8-11.7]; P < 0.001). Conclusion The results based on Japanese clinical practices verified the tolerability of regorafenib in advanced HCC. Major regorafenib-associated adverse events were similar to those related to sorafenib. OS was significantly longer than expected, which might be associated with the sequential systemic therapies after regorafenib, mainly lenvatinib.

Career Guidance Review
NCGE welcomes the launch (24/04) of the Report of the Independent Review of Career Guidance Tools and Information by The Minister for Education and Skills Joe McHugh T.D. together with the Minister of State for Higher Education Mary Mitchell O’Connor T.D. and Minister of State for Training, Skills, Innovation, Research and Development John Halligan T.D.
To access the Indecon report (and the accompanying DES press release), go to: HERE
See below for the full response of the NCGE Management of Guidance Committee
Statement issued by the NCGE Management of Guidance Committee
Ref - DES-Indecon Review of Career Guidance
NCGE welcomes the Indecon Review of Career Guidance Final Report published on Wednesday, 24th April 2019. The extensive stakeholder consultation process engaged by Indecon and the contribution of the Steering Committee to the Review is acknowledged. As an agency of the Department of Education and Skills, NCGE was invited to provide contextual background information on National and European policy and practice in Guidance in advance of the stakeholder consultation process. In addition, Indecon received a written submission from the NCGE Management of Guidance Committee, and the Director and Chair were invited to the Stakeholder Forum in July 2018.
NCGE particularly welcomes the attention given by the Report to the need for effective and inclusive career guidance policy and strategy at a national level including a specific focus on high quality career tools and information as per the Terms and Reference of the Review.
NCGE welcomes the Report’s analysis of the current policy framework and organisational structure for career guidance in Ireland. We note that the Report identifies the challenges emanating from the disparate nature of policy, practice and funding provision in guidance. We recognise the Report’s acknowledgment that this current status can “result in problems of co-operation and co-ordination” (p.3).
The Report affirms the expertise of NCGE in supporting the development of guidance policy and practice. In outlining the structure of NCGE (p. 7), the Report has identified the complexity of NCGE’s role as currently established under Léargas, for example, acknowledging that NCGE cannot access Erasmus+ funding due to this current structure.
NCGE believes, having closely reviewed the 18 Recommendations, that Recommendations 1-5 coming under the heading Reforms to Governance and Delivery Arrangements need urgent priority for the remaining Recommendations 6-18 to have traction.
NCGE is encouraged by the Minister’s statement accompanying the launch of the Review and his announcement of the establishment of a Department of Education and Skills Internal Implementation Task Force.
We look forward to engaging with this Task Force as a key stakeholder.
Management of Guidance Committee

Penguin presents the complete, unabridged audiobook of Wonder by R. J. Palacio, read by Nick Podehl, Kate Rudd and Diana Steele.
'My name is August. I won't describe what I look like. Whatever you're thinking, it's probably worse.' Auggie wants to be an ordinary ten-year-old. He does ordinary things - eating ice cream, playing on his Xbox. He feels ordinary - inside. But ordinary kids don't make other ordinary kids run away screaming in playgrounds. Ordinary kids aren't stared at wherever they go.
Born with a terrible facial abnormality, Auggie has been home-schooled by his parents his whole life. Now, for the first time, he's being sent to a real school. All he wants is to be accepted - but can he convince his new classmates that he's just like them, underneath it all?
Astonishingly powerful, Wonder is a read you'll never forget.

Trump claims Cohen hush money payment was 'simple private transaction'
By CAITLIN OPRYSKO
President Donald Trump on Monday sought to downplay the felony his former personal attorney Michael Cohen pleaded guilty to this month, arguing that Cohen’s hush money payments on behalf of Trump were a “simple private transaction” rather than a breach of campaign finance law.
Apparently citing a Fox News segment, Trump insisted on Twitter that there is “no smocking [sic] gun” pointing to coordination between the Trump campaign and Russia that emerged from the closed door congressional testimony of former FBI Director James Comey last week.
He accused Democrats — several of whom spoke publicly over the weekend to slam Trump following revelations in a series of sentencing memos from special counsel Robert Mueller over the past week — of pivoting to the hush money payments because of a lack of evidence of collusion.
"There was NO COLLUSION,” Trump wrote on Monday. “So now the Dems go to a simple private transaction, wrongly call it a campaign contribution, which it was not (but even if it was, it is only a CIVIL CASE, like Obama’s - but it was done correctly by a lawyer and there would not even be a fine.).”
Cohen, Trump’s former personal attorney and fixer, pleaded guilty in August to paying off women, including an adult film actress and a Playboy model, who alleged affairs with Trump in return for silence, testifying that he did so at Trump’s behest in an attempt to influence the campaign. Trump and his allies have argued that the payments should have been considered a business expense rather than a campaign contribution. But even if the payments were ruled to be an illegal campaign contribution, many legal experts have said Trump would not necessarily share equally in Cohen's guilt.
Even as Trump claimed the payments have been misconstrued, on Monday he tried to argue that Cohen’s charges were no different from thecampaign finance violations made by former President Barack Obama’s 2008 campaign, which included missing filing deadlines for certain contributions and resulted in a massive fine.
Cohen’s payments were by the book, the president argued, but if they were not, it’s the “lawyer’s liability if he made a mistake, not me."
“Cohen just trying to get his sentence reduced,” he added of his former attorney, a man who once said he would take a bullet for Trump.
Cohen is set to be sentenced on Wednesday, and federal prosecutors on Friday have recommended that he serve “substantial” prison time of nearly four years despite his cooperation.

State companies, small businesses must be global players in ICT, says minister
Telecommunications Minister Siyabonga Cwele
By: African News Agency

Font size: -+
The South African government was working to position state entities and small businesses as global players in the field of information and communication technology (ICT), according to telecommunications minister Siyabonga Cwele.
“Our priority focus is to demonopolise the electronic and manufacturing sectors [to] help us to create platforms for our State-owned companies (SOCs) and Small, Medium and Micro Enterprises (SMMES) to emerge as global ICT players and to achieve equitable distribution of ICT networks, products and services,” Cwele said on Friday.
He was speaking at the Inkosi Albert Luthuli International Convention Centre in Durban on the first day of the BRICS Communications and ICT ministerial meeting.
Cwele was joined by ministers from BRICS countries (Brazil, Russia, India, China, South Africa) who were meeting under the theme of “Advancing inclusive growth through industry and SMME participation”.
The minister said it was decided to hold the meeting just a day after the ITU Telecom World 2018 conference ended to “leverage on the participation of the big and small industry players as well as the participation of policy and regulatory leaders”.
BRICS offered a platform for new thinking on how best to create a communications’ environment that responded to the needs of all people and countries, he said.
South Africa had a vibrant ICT sector of big industry players, tech entrepreneurs and small enterprises that were developing infrastructure, equipment and applications to meet the demands of the digital economy.
“Digital development is an important input in the drive towards the Fourth Industrial Revolution. Earlier this year, we announced that government will establish a Commission on the Fourth Industrial Revolution to advise and help us to develop a comprehensive strategy and plan on this important issue of our times.
“This Commission will be inclusive to ensure that all stakeholders such as labour, other civil society formations, business and academia are part of the evolution of our policies and strategies which will ensure their buy-in. The process to do this is at an advanced stage and will be concluded soon,” said Cwele.
“Currently in South Africa we have prioritised the roll-out of infrastructure, in particular through our SA Connect Broadband Plan, and through the development of a Wireless Open Access Network.
“Our intention is to ensure that everyone has access to Broadband at affordable prices. To do this, we intend to produce aspects of the broadband infrastructure network from cabling to end-devices locally.
“We are also looking to license high demand spectrum to enhance new services. This includes rolling-out 5G networks in our country. This network infrastructure will be critical to our development and I believe will help us in our national investment drive which is being led by president Cyril Ramaphosa,” he said.
Cwele also encouraged “our BRICS friends” to partner with the country to expand infrastructure roll-out in Africa. “As a continent, we are still faced with gaps in cross-border connectivity as well as intra-country broadband rollout.”

2006 LA Auto Show Report 5

Lamborghini Steals The Show With Two Stunners
Lamborghini showed its Gallardo Spyder at the official press conference for the L.A. Auto Show. The Spyder has a black fabric roof that can be raised or lowered in about 20 seconds. The Gallardo's space frame has been stiffened and reinforced in many areas, as was the windshield frame. The Spyder is equipped with a rollover protection system comprising two "pop up" hoops with airbags behind the driver and passenger. The Spyder also gets a 20-hp bump in power bringing the 5.0-liter V10's power to a grand total of 520 at 8000 rpm. The six-speed gearbox has lower ratios in each gear, too. This should provide even more impressive acceleration than the Gallardo we tested a couple years ago. We'll have a chance to try the new Spyder in Miami about two weeks from now. Can't wait.
Well, the Gallardo Spyder is certainly cool. But the big news happened after the show closed. Last night we went to a Lamborghini party at the Museum of Television and Radio in Beverly Hills. There were more than a few celebs at this shindig including PM's own Jay Leno who, unlike us, has a couple Lamborghinis in his garage. One of his favorites (and ours) is the Miura. The Miura, produced between 1966 and 1972, turned the automotive world on its ear when it debuted with drop-dead gorgeous bodywork and a powerful V12 engine to match. To help celebrate the Miura's 40th birthday, Lamborghini unveiled the Miura concept. As you can see by the photo, the concept is remarkably faithful to the original. And just for the record, it looks even better in person. The mechanicals are from the Gallardo so that means V10 power. The official word is that this is just a concept. But small companies like Lamborghini don't build frivolous concept cars just for fun. And this Miura looked too "finished" to be merely an homage to the original. Let's hope they build it ... with V12 power, just like the original. The Miura concept is being air-shipped today to Detroit for the auto show next week. So if you're planning on going to the North American International Auto Show you can check it out there.

APPLETON - Principal Financial Group is donating $100,000 through its foundation to the city for new playground equipment at Jones Park.
The equipment is part of a $4.2 million remake of the downtown park. It follows an earlier public-private commitment from Miron Construction, which agreed to donate the park's new 2,600-foot amphitheater.
The Principal donation was approved by the Parks and Recreation Committee on Monday and will move forward as a recommendation to the Common Council on Oct. 3.

The grant was submitted through a partnership between the city's Parks and Recreation Department and Creative Downtown Appleton Inc.
It's all about enriching the downtown's urban design and public spaces and creating an inclusive living area, said Jennifer Stephany, executive director of Appleton Downtown Inc.
Kari Romenesko, client service manager for Principal, said the grant to Jones Park should be considered an anniversary gift to the city as part of the 15th anniversary of the company's downtown office.
"The renovation creates a unique opportunity for Principal to support the first ever public/private park project in Appleton," Romenesko said via e-mail.
"Jones Park is only one block from the Principal office in downtown Appleton. It is a park used by employees during office hours as a relaxing green space to take a break from work and used outside of office hours for employees to enjoy with their families."
The city approved a $100,000 contract on Sept. 19 to playground supplier Lee Recreation, the city's top choice among several proposals to supply playground equipment.
The $100,000 designated for the playground originally would have come out of the Parks Department' budget.
Tom Flick, deputy director of Parks, Recreation & Facilities Management, said it was a joint effort between the city and Principal to make the Jones Park playground happen.
"This donation allows us to pursue other amenities within the park to implement the master plan," Flick said.
Principal will be financing the playground installation and equipment once the donation is approved by the council. The donation would be acknowledged by a marker in the park saying the playground was made possible by Principal.
Flick told the committee Jones Park's timeline for completion is continuing to progress with the ADA ramping system near completion along with the pavilion warming house.
The playground installation is set to begin Oct. 8 and the city hopes to break ground on the Miron-sponsored amphitheater soon.
The timeline for Jones Park is updated every few weeks by Parks and Recreation and can be found on their website, http://appletonparkandrec.org.

Top 3 funniest movie birthing scenes
By Pregnancy Editors
Expectant moms often spend a good deal of time preparing for delivery, from attending birthing classes to meeting with their physician. But everyone needs a bit of comic relief every now and then, and Hollywood is always ready to step up to the plate. Several landmark films have shared their unique take on the birthing process. The field spans from the outrageous, with a mimed performance of a grown man giving birth to another grown man in Austin Powers: Gold Member, to the melodramatic, when Kevin Bacon is kept out of the birthing room in She’s Having a Baby.
Here are the top contenders for the funniest portrayals of going into labor:
Baby Mama
Kate Holbrook, played by Tina Fey, decides she’s ready to start a family and enlists the help of a surrogate Angie Ostrowiski, played by Amy Poehler. Hijinks ensue and over the course of an hour or so, it’s revealed that the baby Angie is carrying is actually her own after a failed in vitro attempt. Just as the two leading ladies reconcile, Angie’s water breaks and she hysterically makes her way through the hospital with an expletive-filled rant, taking down anything and anyone in her way, including other patients receiving care. Holbrook collapses in the delivery room as the baby is born.
This famed British crew of comics created a hilarious sketch filled with incompetent doctors and an absurd lack of concern for the woman in labor (including one physician instructing her to do nothing because “she is not qualified”). A huge crowd is invited to observe this intimate moment and stand in the corner furiously scribbling notes. The whole scene reads more as an opportunity for medical staff to parade their expertise.
Films portraying women screaming in pain in the delivery room is nothing new, but the vehemence with which Katherine Heigl (playing Alison Scott) screams “Get out!” when one of the father’s friends (played by Jay Baruchel) opens the door is definitely a memorable moment. Baruchel scuttles out of the room and warns the other friends and family in the waiting room, “Don’t go in there. Promise me you won’t go in there.”
The Editors at Pregnancy are constantly scouring the news and best information to provide readers with the most accurate advice and latest trends in pregnancy and new motherhood. Together we’ve experienced most of the ups and downs of the pregnancy journey and are here to share and help you along the way.

Road Safety programme celebrates 10 years
More than 8,000 children are safer on our roads thanks to the Southland Seen and Safe road safety programme, which celebrated 10 years last week. Developed by Plunket Injury Prevention Manager Kathryn Impelmans and supported by organisations such as Road Safety Southland, Wensley’s Cycles and The Warehouse, the Southland Seen and Safe programme aims to reduce fatalities and injuries by talking to families with children under the age of 5 about road safety. “We are so grateful to these organisations who work with us to ensure our young people are visible on our roads,” says Ms Impelmans.
PlunketLine celebrates its 25th birthday
More than two million parents and caregivers have called Plunket’s 24/7 parent helpline when they have needed advice on the health and wellbeing of their child or whānau. Plunket staff are celebrating the milestone this month, which included a morning tea with the Prime Minister Rt Hon Jacinda Ardern and Associate Minister of Health Julie Anne Genter, along with other special guests. "We are absolutely privileged and lucky to have this service in New Zealand because it is unique and it is part of our fabric as a nation,” Ms Ardern said.

New partnership renews push for zero pre-schooler drownings by 2020
A new partnership between YMCA Auckland, Plunket and Auckland Council is increasing the push for zero drownings in the under-five age group across Auckland.

CivicCon launches Center for Civic Engagement to turn good ideas into action

After a year of bringing the country's foremost thinkers on creating thriving cities to Pensacola, CivicCon is ready to turn words into action.
October marked the soft launch of the Center for Civic Engagement, an education and resource center designed to help citizens become more effective advocates for themselves and their communities.
Whether citizens want to advocate for more sidewalks, learn more about development code, organize a neighborhood cleanup or just meet other civic-minded folks, the purpose of the Civic Engagement Center is to teach citizens how to get things done, and then empower them to share that knowledge with others.
"The vision is that the Center for Civic Engagement will be a physical location that will be a repository for resources and also an online presence to help citizens and community groups to self-advocate," said Will Dunaway, a member of the center's steering committee.

The center's home will be the new Studer Community Institute building on West Garden Street, formerly the SunTrust Building. The center is planned to include a full staff, a 100-seat classroom, spaces for neighborhood and town hall meetings and other resources.
The center will co-exist alongside CivicCon's flagship speaker series, a partnership between the News Journal and the Studer Community Institute to make Pensacola a better place to live, work, grow and invest through smart planning and civic conversations.
The center will feature its own speakers and educational programs featuring both outside experts and leaders from inside our own community.
“We're going to provide the resources, we're going to provide the education, and we're going to be a clearing house for what you're doing positively.”
Will Dunaway, member of center's steering committee
The center's first event was a two-day series of civic training sessions featuring former Florida governor and U.S. Sen. Bob Graham. In three separate sessions attended by 60 community members, Graham gave a comprehensive breakdown of the core skills citizens need to create change.
He summarized them as passion, perseverance and an understanding of what it takes to get the job done.
Graham said competencies such as knowing what government officials to contact for a specific problem, understanding how to conduct research to support a position and being able to present an argument effectively were critical to any successful citizen effort.
Thankfully, he said, initiatives like CivicCon and the Center for Civic Engagement are popping up around the country and helping citizens develop the skills that they need.
"I am a big believer in the 'up from the grassroots' approach to problem solving, and I think that's where the best ideas will come from," Graham told the attendees of one of his training sessions. "The ideas that will have the most acceptance will come from the community. ... We can't wait for Washington to bring us an answer, we need to bring forward the answer ourselves."
Basil Kuloba, a University of West Florida student and a member of the student board at the Bob Graham Center for Public Service at the University of Florida, helped coordinate for 10 UWF students to participate in the training sessions. He said he was thankful that the center was reaching out to engage college students.
"The truth is, we are the ones who are going to live with the decisions that are being made today," Kuloba said. "It's important that we don't stand idly by while people decide our future for us."

• Donald Shoup on creating readily available parking without new asphalt

Dunaway said in addition to training, the center will work to identify and connect people who are already doing great work in the community.
"There are certain communities and neighborhoods that have been very effective at organizing and self-advocating," Dunaway said. "How do we get the lessons they've learned over to communities that have not had a history of organizing and advocating, or who have tried and not been as successful?"
The Center for Civic Engagement will work to bridge that gap by linking together neighborhood associations and community leaders and helping them share approaches for common or complex problems.
"The idea is the center goes where the public input takes it," Dunaway said. "We have a vision and an idea, but we're not developing or dictating the issues or the causes (people pursue). We're just trying to help facilitate."

The center is leading one project, but it will be driven by community.
Gena Wirth, the design principal at landscaper firm SCAPE and a former CivicCon speaker, will spend five months in Pensacola with her team to envision a plan for improving the waterfront from 17th Avenue to Joe Patti's. SCAPE has already laid groundwork for the plan during an open-to-the-public planning session, and the team will flesh out its work with more input from local experts and community charrettes.
The goal is to make the Pensacola waterfront more accessible to the public, more resilient to weather and climate events, better connected with the surrounding neighborhoods and a more beautiful and pleasant place for everyone.

The initial funding for the center will be donated by local philanthropists Quint and Rishy Studer.
As the Center for Civic Engagement gears up for the grand opening of its physical space, Dunaway told attendees of Graham's training session that his hope is they would become a core group identifying problems from East Hill, to Warrington, to Beulah, to Walnut Hill.
Then, Dunaway said, the intention is that they would take solving those issues into their own hands.
"We're going to provide the resources, we're going to provide the education, and we're going to be a clearing house for what you're doing positively," Dunaway told an eager group. "So go do it!"

Press Releases & News Project A
misterb&b, Largest Gay Hotelier in the World, Raises $8.5M in Series A Funding
(June 7, 2017) San Francisco, CA - misterb&b, the largest gay hotelier in the world with 100,000 hosts in 135 countries, has closed a $8.5 million Series A funding round led by Berlin-based VC Project A and primarily France based VC Ventech. With the new funding push, misterb&b plans to expand its global operations, and to continue on the path to becoming the central platform for gay travel.
The idea for starting misterb&b was first conceived in 2013 after founder Matthieu Jost had a negative experience while traveling with his partner and didn't feel welcome by his host. This was when he started to follow his vision of contributing to building a world where members of the LGBTQA community can travel safely and comfortably at an affordable price and bond with like-minded travellers within the community. The goal is to make misterb&b the global LGBTQA platform for traveling, connecting in real life and feeling welcome everywhere.
“While the sharing economy for short-term rentals has increased, it has been difficult for gay hosts and travellers to feel secure and welcome”, says misterb&b CEO Matthieu Jost. “We look forward to expanding our services backed by two strong investors, so even more members of the LGBTQA community can connect globally and feel safe and welcome anywhere they travel.”
misterb&b is a response to strong demands for collaborative tourism in the booming niche of global gay tourism, a $100B market. The gay market is also a premium segment, traveling twice as much as other travellers.
"With great dedication and a strong vision, the misterb&b founders have built an impressive platform in a very attractive global market", says Anton Waitz, General Partner at Project A, who will be taking a seat on misterb&b’s board of directors. "We are excited to have misterb&b as the first company with roots in France joining our portfolio, and are looking forward to supporting them with our team of 100 operational experts."
Jean Bourcereau, managing partner at Ventech, who will also be joining misterb&b’s board of directors, says: “The online travel industry is already generating massive business worldwide and innovation keeps on thriving in this sector. misterb&b’s early commercial traction and tremendous growth over the past two years have proven the huge value of their differentiated offer for both hosts and guests.”
About misterb&b
Founded in 2014 by Matthieu Jost, Marc Dedonder, François de Landes and Chris Sinton, misterb&b is the world’s largest marketplace connecting like-minded travellers and hosts in the LGBT community. They are able to list, discover and book welcoming accommodations worldwide with 100,000 hosts in over 135 countries. misterb&b will further pursue its global approach to bringing gay men and women together in real-life experiences while expanding its operations in Paris, Los Angeles and Lima. misterb&b’s free app is available on iOS, Android and the web.

How to send large files for free
Need to transfer something hefty to somebody over the internet, but don’t know how to send large files online? We’ve got your back. Large file transfers can be done in a few different ways, so we’ve put together this guide to cover the simplest, most effective, and most secure methods.
No matter what you’re trying to send, the techniques listed below will help you get the job done without paying a dime. Here’s how to send large files for free.
Compress files before sending
Regardless of how you choose to send your file, making it smaller will only help in terms of storage. File compression will not only shrink whatever you’re trying to send, but it’ll make the transfer go faster regardless of which method you’re using — be it email, FTP, or cloud storage. The same goes for smartphone users too.
Most computers come with file compression utilities built in, so making a ZIP file only takes a few clicks. Here’s how it’s done.
Find the file you want to compress Find the file you want to compress
Right click on it and select Send to Two-finger click/control+click on the file
Choose Compressed (zipped) folder Select Compress … [file name]
If you’re transferring music or video, we suggest using RAR compression instead of ZIP because it uses a better compression algorithm that generally cuts down on data loss and file corruption. We recommend using 7-Zip for this, as the open-source file archivist is one of the best currently available.
Upload to a Cloud storage service
The best, and most popular, option for transferring large files is to upload them to an online storage service where your desired recipient can download them. Thanks to the rise of cloud computing, there are a zillion of these types of services, so we’ve taken the time to pick out some of the best ones for you.
Below you’ll find a quick list of our current favorites, all of which offer plenty of storage space, security, and sharing features. We won’t get into specifics on how to use each program, but will instead provide quick descriptions to help you find a service that suits your needs.
Google Drive offers up to 15GB of free storage and allows you to share large files, such as pictures and video, in just a few clicks. It even has backup and syncing options, which are useful features to have.
If you’ve already got a Gmail account, you can’t beat the simplicity of Drive, as it’s effectively built right into the email service. You can “attach” files to emails that are stored on your drive account in order to share them just by clicking the Google Drive logo in the email composition window.
Upgrading to the paid version of Drive nets you 100GB of storage for $2 per month or a full terabyte of storage — that’s 1,000GB — for $10. There’s also a 10TB option for $100 a month and larger packages beyond that if you plan to share a lot of big files.

Most often compared to Google Drive, Dropbox is another great cloud storage option that offers 2GB of free storage space and a Prosyscom Tech of sharing options. The basic suite of features is more or less the same as Google Drive, but Dropbox also offers a mobile app for non-Android and iOS devices, such as the Kindle Fire.
You can expand your own storage options in a few interesting ways, but premium accounts are also available. For $10 a month, you get a Plus account with a terabyte of space, while $20 a month gives you a few advanced features, along with advanced sharing controls, including the ability to set passwords and create expiring links.
Microsoft’s OneDrive service has seen significant upgrades and renovation over the years, making it one of the more competitive solutions for storing files and folders online. With its shared folder system, you can share anything you want at any time and stop doing so at the click of a button when you’re done. A free package nets you 5 gigabytes of free storage, while $2 a month bumps that to 50GB. The $7 -a-month package increases that to a terabyte and gives you the cheapest avenue to increase your daily file-sharing limit. If you’re subscribed to Office 365, you also can enjoy 1TB of OneDrive storage for free as part of your plan.
Box has a little more of a business-slant than some of the other offerings in this section. While that doesn’t mean it lacks features applicable to individuals, to access its file and folder-sharing features, you will need to buy into a Business account, which requires a minimum of three users. Each will cost $15 a month. It also has a free storage offering and affordable packages.
Files and folders shared over those accounts can be password protected, so that’s a useful security feature that makes Box a great choice for those concerned about the privacy and security of their data.
MediaFire offers 50GB of free storage and boasts incredibly simple sharing tools. There is, however, a 20GB max upload size with the free plan, but large files can still be uploaded with no issues. You can also land a 1TB for $3.75 a month.
At this point, we’re basically just giving you a laundry list of different options that perform the same service. WeTransfer is free and it allows users to send files up to 2GB without even registering their name or email address, along with a host of other features.
For those who don’t mind spending a little to get a little more, WeTransfer also offers a $12-a-month “Plus” package that lets you send up to 20GB at a time and store up to 100GB on its servers. It also enables password protection on shared folders.

The Kochs Make News as Voters in Primaries Threaten to Turn Races Upside Down
Submitted by Mary Bottari on April 5, 2016 - 10:43am
MADISON -- It's primary day in Wisconsin and voters are predicted to turn the political establishment upside down.
According to last week's Marquette University poll, Wisconsin voters are backing candidates who are not frontrunners in both parties—highly unusual behavior in a state that has tended to vote for the frontrunner (at least since 1988 when Wisconsin Democrats swung with Gary Hart).
While Ted Cruz and Bernie Sanders may have the edge, no one is counting out Hillary Clinton or Donald Trump. Trump even jetted to far north Superior in a bid for the delegates in the 7th Congressional District. Superior may not have seen a presidential candidate since John Kennedy in 1960.
But it is not just the candidates who are making news in Wisconsin this week. Once again the Koch brothers are in the headlines in a state that they have heavily influenced since helping to elect Scott Walker in 2010.
Charles Koch Has a Plan for the GOP Convention
Ryan Grimm and Sam Stein reported yesterday in the Huffington Post that Charles Koch is confident that Wisconsin native and current House Speaker Paul Ryan could emerge from the Republican National Convention as the party's nominee if Donald Trump comes up short on delegates.
According to their unnamed sources, "Koch believes Ryan would be a 'shoo-in' at a contested convention, should the campaign get to that point."
Although Ryan has been dismissing such talk, Ryan also rejected calls for him to be Speaker of the House until he took the gavel from Boehner in 2015.
Koch Industries PAC is one of Ryan's top 10 career contributors, according to Open Secrets. It was notable to CMD that Ryan recently did a 180-degree turn on criminal justice reform, shortly after the Kochs signaled their support for self-serving criminal justice reform. Ryan has appeared at several Koch summits, has spoken frequently to the Kochs' Americans for Prosperity group, and Politico's Ken Vogel reported in 2012 that the Kochs may have helped Ryan secure the VP slot on the Romney ticket.
Kochs Go to Bat for U.S. Senator Ron Johnson
In other Koch news, Patrick Marley at the Milwaukee Journal Sentinel reported yesterday the Kochs' Americans for Prosperity astroturf group would be spending in Russ Feingold's race against incumbent U.S. Senator Ron Johnson.
They will spend $1 million in four weeks with positive ads trying to raise the profile of Johnson, who is virtually unknown in the state. While Feingold visited every one of Wisconsin's 72 counties every year during his time in the U.S. Senate, Johnson rarely faces the public, preferring to have controlled "telephonic" town hall meetings.
Other dark money groups backed by millionaires and billionaires are prepping to unload on Feingold including "Restoration PAC," bankrolled by Wisconsin businessman Richard Uihlein, and "Reform America Fund," bankrolled by toilet magnate Terry Kohler. Uihlein spent some $500,000 on ads supporting Johnson last year.
Reform America was recently registered by Koch operative Lorri Pickens at the FEC. Kohler has long worked with Scott Walker's campaign guru R.J. Johnson, and was last spotted in an unseemly scandal regarding a $500,000 government appropriation for a phony sporting organization packed with Koch insiders.
This is an unprecedented pattern in Wisconsin politics. Politicians no longer have to travel the state, meet constituents, and earn media if they have millionaires willing to spend on positive ads to boost their poll numbers and attack their opponents.
Will Undisclosed Dark Money Be the Big Winner in the WI Supreme Court Race?
Finally, Koch money could also be in play in a close Wisconsin Supreme Court race where a dark money group called "Wisconsin Alliance for Reform" is spending $2.6 million on misleading attack ads on Wisconsin Judge Joanne Kloppenburg, according to an estimate from the nonprofit Wisconsin Democracy Campaign.
As CMD uncovered, WAR was also registered by Pickens, who has served as a dark money maven in the state for many decades. Pickens was involved in another Supreme Court race in 1997 that resulted in $60,000 in fines for illegal coordination between the committee of Justice Jon Wilcox and a purportedly independent third party group run by Pickens' husband and Mark Block. Pickens has worked for the Koch's Americans for Prosperity and numerous other groups that pushed for a trio of bills in 2015 that laid to waste Wisconsin's anti-corruption laws. One of the bills allowed unlimited undisclosed dark money into Wisconsin campaigns and elections for the first time.
While the Kochs and their servants are working hard to keep voters in the dark on election day, disclosure in campaign financing is broadly supported by the American public, including Republicans. In a recent poll, 77 percent of Americans want limits on money in politics and 88 percent wanted to "make fundamental changes" or "completely rebuild" the campaign finance system.
Koch Fingerprints on Wisconsin Voter Supression
Today also marks for many Wisconsin voters their first encounter with the state's Koch-backed and ALEC-inspired voter ID law which threatens to disenfranchise up to 300,000 eligible voters who lack needed ID.
While the law explicitly requires a public campaign to educate voters about new ID requirements, it is no coincidence that the state legislature hasn't appropriated money to run public service ads in this cycle. Democracy advocates will be on the look-out for problems, and voters facing problems can call an emergency hotline: 1-866- OUR-VOTE.
Despite a near-total absence of in-person voter fraud, voter ID was passed in 2011 but immediately drew legal challenges and a court injunction. An all-Republican panel of 7th Circuit justices reinstated voter ID just a few weeks before the November 2014 election. When the full court—whose eleventh seat has been vacant since 2010—heard the case, it issued a 5-5 decision split along party lines, leaving the panel's ruling intact.
Backed by the same political network that pushed voter ID through in the first place, the Senator who has been blocking that 7th Circuit appointment for nearly six years is none other than Ron Johnson.

Trumps message failed to resonate
As someone who travels frequently to Brussels and other parts of the world, I do not think terrorists attacks are in the least bit funny. As someone who lives in Wisconsin, there is no doubt that Trump ads featuring terrorist threats failed to resonate with voters. He struggled to break 35%.

What does the future hold for Peterborough City Council - James Palmer
Stephen Briggs
Published: 12:00 Sunday 15 April 2018
Mayor of Cambridgeshire and Peterborough James Palmer says he things the Combined Authority and Peterborough City Council will work strongly together, in response to former city councillor Charles Swift's fears the city council may be disbanded.
In response to Charles Swift OBE, who fears that Peterborough City Council may be abolished now that we have a Cambridgeshire and Peterborough Combined Authority, let me make absolutely clear that while I’m Mayor, that will never happen.
Let’s also be clear about what the Combined Authority is for. Last year, the government offered Cambridgeshire and Peterborough a devolution deal that would bring powers back to regions. The resultant Combined Authority was given a strategic responsibility and funding to deliver housing and transport infrastructure as well as improve skills and education.
As mayor, my focus is on these key areas, and in order to deliver for the people of Peterborough, I am working closely with Peterborough City Council take advantage of the opportunity devolution has presented us.
That’s why last month the Combined Authority agreed to put in £9.74 million to help develop the first phase of the University of Peterborough – a learning institution that will have its own powers to award degrees, and focus on the skills this region needs to make its workforce more competitive and boost the economy. Of the options on the table for us, the Combined Authority chose to invest the maximum amount into the University, to offer places for twice as many students and offer a sensible, single-site interim facility at the Embankment. This project was an absolute cornerstone of the devolution deal and I was delighted to help get the ball rolling on the first phase.
I’m championing the case for full dualling of the A47 from Peterborough to Wisbech, to help unlock more of the economic potential of the northern part of the county. I felt the original Highways England A47 proposals of dualling from Warnsford to Sutton and improving the Guyhirn roundabout were simply not ambitious enough. So a business case has been commissioned by the Combined Authority for a full dualling, and I will be meeting with the chief executive of Highways England soon.
And this year the Combined Authority was successful in bidding for £4.57 million from the Government for the Yaxley loop road, which will bring forward an additional and much needed 5,350 homes for Peterborough.
These are all projects which are being taken forward alongside the good work that Peterborough’s city council is already doing. Indeed, the leader of Peterborough City Council, Cllr John Holdich, is a key part of the Combined Authority Board and one of my deputy mayors and I work with him closely.
Let me assure Mr Swift that the Combined Authority and the City Council has a good working relationship that is already bearing fruit.
An independent review of the current structure of local government in Cambridgeshire and Peterborough has been commissioned by the Combined Authority, which will set out to find how things could be done better, and whether we can save some tax payers’ money in the process. That will report in the autumn and I look forward to the results.
I understand the reasons why Peterborough broke off from Cambridgeshire County Council in the late 1990s and I respect the decision that was made. As Mayor, I am in full support of a strong, independent unitary council for Peterborough.

(artificial) News
June 23, 2018 coolpete 1 Comment Amazon, Billionaire, Jeff Bezos, Trillionaire
UPDATE: Pete the Cooler has been following this story since December 2017 (originally reported here) and I have provided ongoing updates to the story here, here, here, and here. Jeff Bezos may be the richest single person on the planet as his wealth hits $141 Billion, but Bezos is still poor in one way. Jeff suffers from a serious shrinking condition known as Concave Billionis Plasmolysis. Unfortunately for Jeff, even the recent Supreme Court decision allowing states to collect sales tax on internet purchases is unlikely to stop his growing tsunami of riches.
Jeff Bezos’ medical condition is quite rare, affecting only 1 in 1 trillion people. Its primary and devastating effect is that as personal net worth increases, height decreases. In the Concave phase, it is reversible, so Bezos could cure himself through absolute financial implosion or pre-death charitable distribution of most of his wealth. Unfortunately, if his wealth continues to accumulate, the condition will develop into Convex Trillionis Plasmolysis, which is irreversible and would leave Jeff Bezos a very tiny man, permanently.
Poor Jeff Bezos
Jeff’s recent financial gains have robbed him of yet another half-inch from his rapidly diminishing vertical height. The new shrinkage of 0.5 inches, reduces his height to 57.9 inches. To put it in perspective, that is the average height of a 12 year-old boy (as you can see from this chart).
At his current financial growth rate, Bezos will be the size of a 9 year-old within the next five years.
We all wish the best for Jeff. And Pete the Cooler is publicly volunteering to help Jeff turn the tide of this serious problem. Jeff, I am willing to accept a large, cash gift from you if it will ensure that you don’t get stepped on or accidentally vacuumed up by a Roomba.
Read the original article below:
Amazon has announced today that its founder and CEO, Jeff Bezos, has been diagnosed with a rare condition known as Billionis Plasmolysis that causes him to shrink in stature as his wealth increases.
With a net worth of approximately $100 billion, the condition is currently in the Concave Billionis Plasmolysis phase, which is still reversible. However, as Bezos’ wealth continues to approach $1 trillion, the condition is expected to become irreversible, a phase known as Convex Trillionis Plasmolysis – which would leave Jeff Bezos a very tiny man, forever.
Jeff Bezos was 5 feet 7-inches when he started Amazon.com in the early 1994. Because Bezos’ current height was not disclosed by Amazon, sources speculated that he may now only stand “a hair” over 5 feet tall. Doctors have indicated they believe Bezos could shrink by as much as 10% for every $100 million in wealth he gains. As a result, Bezos would measure in with a height of only 3 feet 4-inches at a net worth of $500 million and a height of only 1 foot 11-inches by the time he becomes the first Trillionaire in the world. While achieving a net worth of $1 trillion is a remarkable accomplishment, sadly, by that point his condition will have evolved to Convex phase and even losing his wealth through catastrophic financial implosion or philanthropically distributing his wealth would not reverse the effects and he would remain tiny for the remainder of his life (which devastatingly could be forever as the Billionaire class rapidly develops technology to make them immortal.)
Eery Similarities to 1950’s-era Film
The condition, which affects only 1 in 1 trillion people, produces symptoms eerily similar to those presented in the 1957 film, The Incredible Shrinking Man
Scott Carey (Grant Williams) encounters a mysterious radioactive mist on a boating trip and soon finds his life taking on a bizarre and frightening twist. His physical size begins to diminish as he shrinks to a mere two inches. Suddenly ordinary household situations loom over him with lethal intensity: a playful cat becomes a demon and a spider becomes a gargantuan monster. Carey finds he must rely on his wits to survive in his new oversized world in this fascinating film based on Richard Matheson’s riveting screenplay.
Sources report that Jeff Bezos, (on-and-off) the world’s richest man, is very sensitive about about his diminishing stature and fears being tiny, but has decided if he has to be tiny, he will make sure he is THE tiniest man in the world.
Bezos Uses ‘Downsizing’ Film as Propaganda to Normalize Tinyness
Bezos’ concern about his condition may be the reason Amazon Studios aggressively bid for the distribution rights to the new Matt Damon movie, Downsizing.
Friends close to Jeff Bezos believe the film is an attempt to normalize tiny people as his wealth explodes and his stature diminishes.
Additionally, Bezos has reportedly told staff to feature men’s platformed shoes regularly in the Lighting Deals section of Amazon.com.

Phnom Penh Post - Kingdom’s banks see rising foreign influx
Kingdom’s banks see rising foreign influx
Post Staff | Publication date 09 January 2018 | 08:05 ICT
Post Staff
Cambodia’s banking sector saw an almost 32 percent increase in foreign capital inflow in 2017, a result of new foreign banks and stricter capital requirements set by the National Bank of Cambodia, according to the central bank’s annual report.
The nonbanking sector saw a more modest 0.8 percent increase in foreign capital inflow last year, with the real estate and garment sectors experiencing a slight decrease compared to 2016. “Inflows of foreign capital into the Kingdom’s banking sector increased 31.8 percent, thanks to the establishment of the two new banks: [France’s] BRED Bank and [Japan’s] Mizuho Bank,” the report said.
It also noted that the national bank’s March decision to raise the minimum capital requirements for commercial and subsidiaries of foreign banks operating in Cambodia to $75 million contributed to the growth. According to the report, most of the foreign capital inflow came from Asian countries such as China, Vietnam, South Korea, Malaysia, and Singapore.

SoftBank Invests $1B Into Wirecard
Posted on April 24, 2019 April 24, 2019 7:06 am
Wirecard, the German financial company, and Japan’s SoftBank Group announced Wednesday (April 24) a deal in which SoftBank will invest about EUR 900 million in Wirecard.
In a press release, the companies said the investment will come via a convertible bond mechanism. On Tuesday (April 23) Bloomberg reported a deal between the two was imminent. Wirecard said under the deal it will issue convertible bonds to SoftBank with terms of five years. It is convertible for about 5.6 percent of Wirecard stock at EUR 130 per Wirecard share. Shareholders of Wirecard have to sign off on the deal at the company’s annual shareholder meeting on June 18. The two companies also inked a partnership for digital payment solutions in which SoftBank will support Wirecard’s geographic expansion in Japan and South Korea. The two will also look for ways to collaborate in digital payments, data analytics, and AI and other digital financial services. They are also expected to jointly explore new product and service offerings in digital lending.
“As global innovators, we focus heavily on expanding our networks and creating opportunities for companies with groundbreaking ideas. In SoftBank we have found a partner that shares both our passion for new technologies and drive to spearhead the latest innovations, all on a global scale,” said Markus Braun, CEO of Wirecard in the press release. “In addition, through this potential partnership, we will expand our reach and products to the East Asian markets, thereby further strengthening our position in Asia.”
The investment on the part of SoftBank should quell some concerns about Wirecard, which has been embroiled in scandals in recent weeks after a series of articles in The Financial Times alleging faulty accounting in its Singapore office. Based on the accounts of a whistleblower, The Financial Times penned the articles which sent the value of Wirecard plummeting. It also prompted an investigation by the police in Singapore. Wirecard has said the reporting from The Financial Times was “false, inaccurate, misleading and defamatory” and filed a lawsuit against the paper.

Conservation groups urge the NEB to reject Kinder Morgan pipeline
Kinder Morgan application has failed to consider project’s impacts on killer whales, risks of marine spill
Published on 2016 · 01 · 25 by The Raincoast Conservation Foundation
VANCOUVER – The National Energy Board (NEB) must reject Kinder Morgan’s Trans Mountain pipeline project because of gaps and deficiencies found in its application, conservation groups say.
“The quantity of Kinder Morgan’s evidence does not make it quality evidence,” said Karen Campbell, Ecojustice lawyer. “The evidence we will present to the NEB reveals that the Kinder Morgan has downplayed environmental risk and overstated the economic benefits. In our view, the Board has one recommendation option, to reject the Kinder Morgan project.”
Ecojustice lawyers, representing Living Oceans Society and Raincoast Conservation Foundation, will appear before the NEB panel charged with reviewing Kinder Morgan’s Trans Mountain Expansion Project tomorrow to make final arguments against the project.
Written submissions from the groups argue that Kinder Morgan has not provided sufficient information to evaluate the proposed project’s risks, including its effect on endangered Southern Resident Killer Whales, risks to people and communities in the region, and the potential impacts of a major oil spill in the Fraser River or the Salish Sea.
“Kinder Morgan’s application fails to adequately convey the impacts the project will have on the critical habitat of endangered killer whales,” said Misty MacDuffee, conservation biologist with Raincoast Conservation Foundation. “These whales are already at risk of extinction. Our research indicates that the increased underwater noise from Kinder Morgan’s tanker traffic accelerates their decline and increases their risk of extinction.”
Kinder Morgan is proposing to twin its existing Trans Mountain Pipeline. This would increase the amount of oil transported from Edmonton to Burnaby’s Westbridge Terminal from 300,000 barrels per day to 890,000 barrels per day, and increase tanker traffic through Burrard Inlet and the Strait of Georgia by nearly seven times.
“Increased tanker traffic means much greater likelihood of a catastrophic oil spill off of British Columbia’s coast, but Kinder Morgan’s evidence fails to address the possible impacts submerged dilbit could have on the marine environment in the event of a major spill,” said Karen Wristen, Executive Director of Living Oceans Society. “Without that information, it is impossible to properly assess the risk this pipeline poses to B.C.’s coastal communities. As it stands, this pipeline should not be approved.”

“Festivals Will Continue To Come But The Problem Of Noise Pollution Cannot Be Ignored”, Says Bombay High Court
Written By Alisha Nair | Mumbai | Published: September 21, 2018 14:41 IST
Bombay HC said, “festivals will continue to come but the problem of noise pollution cannot be ignored”
Bombay High Court refuses to lift the ban on DJs, loudspeakers during festivals
Taking into the consideration the increase in noise pollution across the state, Bombay High Court refuses to lift the ban on DJs, loudspeakers during festivals.
A petition was filed by Professional Audio and Lighting Association, owners of sound and light rental companies, seeking to declare that there is no prohibition/ban on use of sound system/DJ system in Maharashtra. While hearing the petition, Bombay HC said, “festivals will continue to come but the problem of noise pollution cannot be ignored.”
The petitioners are also seeking guidelines and regulations, within the ambit of which the use of sound systems shall be permissible.
HC announced a complete ban on the use of DJ or sound systems during Ganpati Visarjan (immersion) because of the increasing noise pollution.

In last hearing, defending the ban on use of such sound systems during Ganesh and Navratri festivals, Advocate General Ashutosh Kumbhakoni told the court that, “the moment a DJ or Dolby system is switched on, the noise level is over 100 decibels, way above the ambient level or the maximum permissible limit under the Noise Pollution Rules-2000. The maximum noise levels permissible under the rules for various areas range between 50 and 75 decibels during the day and between 40 and 70 decibels at night.”
Talking to Republic TV Advocate Kumbhakoni said, ”The rules mandate that ambient noise levels must be maintained at public places even during festivals. So, that means the use of DJ, Dolby, or any such high volume audio systems cannot be allowed,” he said. “These instruments are used for amplifying sound levels. So, if their use is not allowed then why should we permit anyone to bring such music systems out on roads or at the pandals.”
The ban was ordered by the state government. The state invoked Section 4 of the Noise Pollution (Regulation and Control) Rules, 2000, while issuing the ban. As per the rules, violators will be issued with a notice and will directly be charge-sheeted. However, there will be no arrest at the time.

Declaring Me Fugitive Offender Is Like Giving 'economic Death Penalty': Vijay Mallya Tells High Court
Embattled liquor tycoon Vijay Mallya told the Bombay High Court on Wednesday, April 24 that by declaring him a fugitive economic offender and allowing attachment of his assets, a special court had awarded him an "economic death penalty"
Later, Mallya approached the high court, challenging the provisions of the act that permit, among other things, confiscation of assets and placing them under the control of the Union government
Embattled liquor tycoon Vijay Mallya told the Bombay High Court on Wednesday, April 24 that by declaring him a fugitive economic offender and allowing attachment of his assets, a special court had awarded him an "economic death penalty".
Mallya made the statement through his counsel Amit Desai before a bench of justices Ranjit More and Bharati Dangre, during arguments on his plea challenging several provisions of the Fugitive Economic Offenders Act that came into existence in August last year.

"My debts and the interest on such debts are mounting. I have assets to pay off these debts but the government won't allow the use of these assets to clear the debts. I have no control over my properties," the businessman said.
"This is an economic death penalty that has been awarded to me," he said.
Desai urged the court to pass an injunction against the proceedings related to confiscation of his assets across the country.
The bench, however, refused to grant any interim relief on the petition.
A special court had in January declared Mallya a fugitive economic offender (FEO) under provisions of the Fugitive Economic Offenders Act.
Later, Mallya approached the high court, challenging the provisions of the act that permit, among other things, confiscation of assets and placing them under the control of the Union government.
He also filed another petition challenging the special court order that declared him an FEO which was being heard by another division bench of the high court.

Desai argued that the FEO Act was "draconian" and "unconstitutional" as it allowed the Centre to confiscate everything, irrespective of whether a property was bought from the proceeds of a crime or not.
Mallya's plea was opposed by the Enforcement Directorate's (ED) counsel D P Singh, who argued that the Act was not draconian at all.
"This act is not draconian. In fact, this act prohibits prosecuting agencies from acting on their own. For everything, including attachment of properties, we are supposed to get a court order that is passed only after hearing all sides," Singh said.
"This act is meant for Mallya-like people only. It is not an ordinary legislation. The act has been constituted to bring back defaulters who have defaulted amounts of Rs 100 crore and above," the counsel said.
The court, too, noted that the legislation was a sound one and not draconian.
"We understand this legislation is a little harsh. But that is because it deals with draconian situations," the bench said.
It, however, issued a notice to the attorney general to respond to Mallya's plea challenging the act.

Snorkel Founder Art Moore Dies at 94
Snorkel announced the passing of its founder Arthur Deshon Moore, a current Snorkel board member, and a pioneer in the access industry, on June 19, 2019, at the age of 94.
Snorkel announced the passing its founder Arthur Deshon Moore, a current Snorkel board member, and a pioneer in the access industry, on June 19, 2019, at the age of 94.
“We have been incredibly fortunate to have been graced with Art's innovative vision, insightful wisdom, whimsical humor and cheerful personality for 94 years,” the company said in a statement. “Known for his drive and determination, Art's career has set an extraordinary example and left a lasting impact on the global work at height industry. His imaginative designs and pursuit for quality helped to shape the industry in its infancy and set standards still followed to present day.”
Developing 17 industry-defining models in less than a decade, Moore built the foundation for Snorkel, today a leading global manufacturer of aerial lifts. He was probably most well-known for the Snorkel TB-42 telescopic boom which became a standard in the industry for many years, as well as the introduction of the first ‘big boom’ which reached 126 feet (38m). His vision will continue to influence the company he started 60 years ago and the industry he changed for the better with his innovations.
Over the years, Art’s industry contributions have been recognized with honors like the International Awards for Powered Access Lifetime Achievement Award in 2016, and induction into the American Rental Association’s Hall of Fame in 2017. Following the acquisition of Snorkel by Don Ahern in October 2013, Art became a Snorkel board member providing his global insight and product knowledge.
“For many years, Art Moore was a mentor to myself and others in the early years of the access rental and dealership business, and he ultimately became a close friend,” said Ahern. “He will be a great miss to Snorkel and the wider industry, and I send my sincere condolences to Sue and family at this difficult time.”
Moore's legacy extends beyond his outstanding achievements in the access industry. He lived for adventure, traveling around the globe, and never shying away from adrenaline with friends and family by his side.
Moore is survived by his wife, Sue, and his daughter, Melissa Moore and husband Aaron Snyder; son Arthur Jr.; daughter Kristyn Sanders; stepdaughter Lourenda Block; and grandchildren, Zen Moore, Aubrey and Ainsley Sanders.
Visitation will be held on Thursday, June 27 from 7:00 to 8:30 p.m. at Meierhoffer Funeral Home in St. Joseph, Mo. A service will be held on Friday, June 28 at 10:00am, followed by a burial in the Memorial Lawn. A Celebration of Life will take place at Snorkel’s Elwood, Kan., facility at noon on Friday, June 28.

Endangered Leatherback Turtle spotted near Vancouver Island
The rare moment was captured by Jeremy Koreski and former Vancouver Canucks defenceman Willie Mitchell

Tofino photographer Jeremy Koreski and former Vancouver Canucks defenceman and co-owner of Tofino Resort and Marina, Willie Mitchell, went fishing for some tuna the other day and returned with one tell-all turtle story.
The fishing buddies and business colleagues say they spotted an endangered Leatherback Turtle near Loudon Canyon in the Barkley Sound. Koreski managed to snap a photo of the marine creature just before it dove under.
“We were probably 30 miles straight out,” said Koreski. “I didn’t realize that [the turtle] was so rare. I guess the last sighting was two years ago and then the only other sighting was two years before that.”
“I wish we had a little bit more time with the turtle. We kind of spotted it and drove up to it and it was taking a few breaths than it dove down.”

This isn’t the first time Koreski and Mitchell have experienced a rare sighting on the water. In the fall of 2017, they claim they saw a salmon shark while cruising around the Clayoquot Canyon.
A website dedicated to Leatherbacks in B.C. describes the turtles as some of the biggest reptiles in the world, and have been around since the dawn of dinosaurs.
However, there have been less than 135 Leatherbacks documented off the Coast of B.C. since the 1930s.
The giant turtles migrate all the way from Indonesia to feed on the jellyfish in North Pacific waters. They have most often been sighted between June and October when jellyfish populations are likely to be greatest.

Threats to the survival of this endangered turtle include: entanglement in fishing gear, collision with boats, and plastic pollution. In a global study of 408 Leatherback Turtles called ‘Leatherback Turtles: The menace of plastic’ by Mrosvosky, autopsy records showed more than 30 per cent had plastics in their intestines.
Sea turtles accidentally eat plastic bags because they cannot tell them apart from their jellyfish prey.

Jeet Kune Do was conceived by Bruce Lee as being his personal form of fighting system, based on his researches and discoveries. It may be taught, but can not be standardized, because each individual has needs which are strictly his own.
Although it also contains techniques of its own, Jeet Kune Do remains a concept. To understand the principles, concepts and strategies of Jeet Kune Do, it is therefore imperative to know and study first and foremost the Jun Fan Gung Fu. In clear, you can not mix combat styles and say, "I do JKD," if you did not learn Jun Fan Gung Fu before. You must study Jun Fan Gung Fu first and go to the pre-phases of JKD.
If we can say, to quote Bruce Lee, that: "Jeet Kune Do integrates everything, but is not integrated in anything", it must be said that certain styles or systems do not fit at all into the structure of Jeet Kune Do, because of their lack of fluidity for example.
Jun Fan Gung Fu, which uses the concepts of Jeet Kune Do, is constantly evolving and Dan Inosanto's contribution is immense. Based on his research (during Bruce's lifetime), Dan included, among others, Panantukan and Sikaran, a Philippine foot-to-hand combat method that further increases the efficiency of the Jun Fan system, not only by its technique itself, which has proven itself, but also by its very sophisticated training method. The Filipino martial arts systems taught by Inosanto, such as the Lacoste system for example, are so similar in concept and practice that they help the understanding and effectiveness of the Jeet Kune Do. Later, the principles and techniques of many other fighting styles such as Savate, Muay Thai, Penjak Silat, Jiu-Jitsu, and Shoot Wrestling were included in the Jun Fan Jeet Kune Do curriculum.

Postal Service Prayer: Deliver Us From Fiscal Doom
White House stops short of calls for outright privatization, but big changes could lie ahead
Posted Dec 20, 2018 5:05 AM

Over the last decade, mail volume has tanked but package delivery has become more important than ever.

The United States Postal Service faces a major policy shakeup at a time when package delivery has become more central to Americans’ lives than ever.
A growing reliance on e-commerce has driven demand for direct-to-door shipping for everything from textbooks to toothbrushes. And to the casual observer, USPS is playing what looks like a seamless part in the process, with more and more packages delivered the “last mile” to customers’ doors by government workers.
But future retirement costs are snowballing and traditional letter mail has dropped drastically since 2006, when Congress made its most recent effort to modernize the mail delivery system and fix its finances. Package revenue is growing at a steady clip, but it pales in comparison to the cratering in letter mail volume. Combined with nearly $150 billion in unfunded liabilities facing the agency, USPS could face a taxpayer bailout and a possible radical drop in services if lawmakers don’t act.
President Donald Trump’s December task force report makes a strong pitch for a legislative overhaul. The report, released Dec. 4, said Congress and the executive branch should change how the mail carrier operates to increase revenues and remain off the taxpayers’ back for unpaid-for debts.
While not calling for outright privatization, the report suggests the White House is looking to shake up the agency’s labor and business models to cut costs and increase efficiency.
The stakes of a collapse of the Postal Service are profound. Seniors could lose steady access to prescriptions, companies’ shipping models could be disrupted, and retirees and employees could lose out on health care, income and wages if the USPS is forced to cut costs to meet retirement demands. Without sufficient cuts or additional money raised, taxpayers could be on the hook to pay for billions in deferred retirement and health liabilities after years of Congress doing nothing.
“It’s the 21st century, and the Postal Service is basically a 20th-century paper-toting entity. You adapt or you die,” said Kevin Kosar, vice president of policy for R Street Institute, who has written on Postal Service finances.
Year after year, the agency continues to end up in the red. USPS reported a $3.9 billion loss for fiscal 2018 in mid-November, marking the 12th consecutive year of net losses. That was largely blamed on a 3.2 billion piece drop-off in letter mail. As a result, USPS missed $6.9 billion in payments for pension and retirement health benefits for the most recent fiscal year. Despite being required to make the payments by law, USPS hasn’t made them since fiscal 2010.
“Growth in our package business will not offset the continuing declines in our mail business. … Simply put, absent legislative and regulatory change, we cannot generate enough revenue or cut enough costs to pay all of our bills,” said Postmaster General and Chief Executive Officer Megan J. Brennan in a Nov. 14 call with reporters on the financial results.
USPS receives no tax dollars for operating expenses and relies on sales to fund operations. But that could change — and service could get a lot more expensive and less reliable as a result — if the federal government doesn’t step in. Already in rural areas, residents are stuck feeling the effects of a decline in letter mail instead of a package delivery renaissance, triggering frustration so severe it’s reaching Washington.
In its approximately 70-page report, the White House broadly recommends changes to the carrier’s employee compensation, business models, and debt restructuring. The report didn’t call for the outright privatization of the mail carrier; rather, it emphasized a need to change the business model so that “correcting the failures and inefficiencies” of the private sector.
Changes by Congress and internally through the administration of USPS would allow, the task force wrote, for the generation of more revenue from commercial mail products to defray the costs of essential service, such as delivering prescriptions to residents in rural America who have no other viable option for getting their mail.
Besides the report, the federal government has fired multiple warning shots this year that change is coming. USPS has also set a number of postage increases that go into effect Jan. 27 in an effort to boost revenue.
Meanwhile, Congress has been hard at work pushing two bipartisan overhaul bills through committee in the House and Senate in 2018. But the election and the president’s sudden interjection into a policy debate that’s been raging for years has unexpectedly changed the stakes.
It’s not an easy problem to solve. Annual operating revenue of nearly $70 billion represents a massive volume of mail that is supposed to pay for operating costs. But time is running out: the nation’s mail carrier is on track to drain all available funds stocked away for retiree health care by 2030. That’s why a future scenario where the agency has to pay benefits on an as-needed basis could trigger a financial meltdown that leads to higher prices and worse service.
In the House Oversight and Government Reform Committee, ranking Democrat Elijah E. Cummings of Maryland and Government Operations Subcommittee Chairman Mark Meadows, a North Carolina Republican, have been pushing for a fix. Meadows identified retooling of the system as a top priority after the exit of the postal overhaul’s original sponsor, GOP Rep. Jason Chaffetz of Utah, who resigned from the House earlier in 2018.
In the Senate, Delaware Democrat Thomas R. Carper has authored similar legislation with powerful co-sponsors: Democrats Heidi Heitkamp of North Dakota and Claire McCaskill of Missouri, as well as Republicans Jerry Moran of Kansas and Roy Blunt of Missouri. But two major advocates for a change — Heitkamp and McCaskill — were just voted out of office.

Dueling masters
Conflict between Congress and the White House could complicate an overhaul.
Cummings, in line to become Oversight and Government Reform chairman in January with Democrats in the majority, railed against Trump’s sudden postal focus at a committee hearing in June.
“Instead of working with us, President Trump unilaterally appointed a task force to come up with his own ideas about the Postal Service,” Cummings said.
The Government Accountability Office has been ringing the alarm bell for years, placing the agency on its “high risk list” and issuing a damning report about the retiree funding cliff in August.
According to that report, USPS had about $149 billion in unfunded liabilities and debt at the end of fiscal 2017: $62.2 billion for unfunded retiree health benefits, an estimated $42.0 billion for pension benefits, $17.9 billion for workers’ compensation and $11.9 billion for other liabilities, as well as $15.0 billion in outstanding debt — the statutory limit.
There’s slightly more flexibility now as the agency paid down $1.8 billion in debt in fiscal 2018, with another $2.2 billion payment scheduled in fiscal 2019. The White House’s task force report, which is slightly more updated with the inclusion of fiscal 2018 data, puts total unfunded liabilities slightly lower at $139.6 billion, $43.5 billion of that for pensions.
Trump’s task force establishment was accompanied by other signs that he wants a big shakeup. The administration proposed privatizing the agency as part of a governmentwide reorganization proposal released in June.
On Twitter, he’s chided USPS as Amazon’s “Delivery Boy,” and suggested the online retailer is ripping off the Postal Service to ship on the cheap. The president has also personally lobbied the postmaster general to raise rates on Amazon, according to multiple reports earlier this year.
Trump’s inclination isn’t outrageous — that private industry might be benefiting more than what it’s paying for the convenience of a national mail system designed to reach every door. Other lawmakers, Republican and Democrat, are suspicious of the same.
But Trump’s basic assumption is incorrect, as turning a profit on package delivery is required under law.
And the conflict represents a larger problem the Postal Service seems to encounter at every policy turn: There’s a general misunderstanding from those who can make a change about what numbers are actually important to turn things around.
For example, part of why the financial mess is so big now is that in 2006, with email taking a bite out of traditional letter delivery, lawmakers grew concerned about USPS’ ability to pay retiree benefits but ended up contributing to the agency’s financial difficulties.
In the 2006 law, Congress required an aggressive prepayment schedule for future retirement benefit costs to ensure that there would be enough to meet pension and health obligations while USPS took steps to become more competitive with the private sector. On paper, it looked like a cost-free fix as well, something that lawmakers are always looking for: The law required USPS, technically an “off-budget” agency,” to park nearly $56 billion in prepaid health benefits over a decade into a new “on-budget” fund, magically creating revenue the Congressional Budget Office “scores” as an offset for other spending in the bill.
Nonetheless, within a few years, USPS found itself unable to make the required prepayments, missing $38.2 billion in required prepayments for retiree health care from fiscal 2010 to fiscal 2017. That occurred after the agency hit its $15 billion statutory debt limit, in part by borrowing billions for the benefit payments that were later halted.
Chutes and ladders
Postal Service data tell a story of declining mail volume followed by a paring down of the agency’s facilities to cut costs. Package growth is a rare bright spot. And the White House report quickly received an unwelcome response from a major group of online shippers that utilize USPS’ package business.
For one, there’s been a big drop-off in the postal physical footprint. USPS data show that from 2006 — when Congress last approved a major overhaul of the system — to 2017, the number of post offices with individual postmasters — the building blocks of the local mail system — was reduced by just over 900, from 27,318 to 26,410.
Factoring in other facilities such as branches and stations that the agency doesn’t officially call post offices, retail locations have shrunk by more than 2,300 just since 2008.
And mail volume has tanked, with the annual number of pieces handled now approximately 63.6 billion below the flow in 2006.
Letter mail seems to have stabilized somewhat — annual mail volume has hovered around 150 billion pieces for the past five years although it still fluctuates, as the fiscal 2018 results showed.
But USPS notched an organizational record for the most packages delivered in a single day in December 2017, at 37 million.
Some stakeholders, including American Postal Workers Union President Mark Dimondstein, don’t think the projections are as grave as the reports imply — as long as Congress fixes the problem it created, and soon.
“There are challenges, there’s no question that first-class letters are less, but our saying is the internet taketh and the internet giveth,” Dimondstein said. “The Postal Service is a wonderful service — it belongs to the people of the country, and it is the low-cost anchor of the package delivery system.”
As mail volume has dropped off, package services are making up an increasing portion of USPS’ business, with the latest results in fiscal 2018 showing package delivery contributed $21.5 billion of the total $70.62 billion in revenue.
That’s a big contribution to the agency’s bottom line. In 2017, USPS reported that packages contributed $7.15 billion after factoring in expenses.
“If you look at what the Postal Service does … packages are the most profitable piece of its business,” said John McHugh, spokesman for the Package Coalition and a Republican former congressman from New York who worked on the 2006 Postal Service law.
“If you’re interested in doing something to help the Postal Service to become more financially stable, the last thing you want to do is negatively impact that one positive portion of the Postal Service’s business,” McHugh says.
The Package Coalition is a group of major business interests, including Amazon, Express Scripts, the Columbia Sportswear Company and the National Retail Federation. It formed this summer in anticipation of postal legislation moving along with White House action.
Following the Dec. 4 report’s release, the coalition issued a statement bristling at task force suggestions. “By raising prices and depriving Americans of affordable delivery services, the Postal Task Force’s package delivery recommendations would harm consumers, large and small businesses, and especially rural communities,” McHugh said in the statement.
In contrast, those shipping everything but packages fear a parcel fixation will prevent a larger overhaul of the agency’s letter business, which operates at a loss even before retirement liabilities are considered.
Hill proposals
Broadly, the House and Senate bills target the same issue: eliminating required prefunding for retirement health and pension benefits. Both bills propose to require health benefit recipients enroll in Medicare to cut costs.
House and Senate bills would also make permanent half of a price increase USPS imposed during the recession to recoup economic losses that expired in 2016. And USPS would be allowed to offer more “nonpostal” services to increase revenue, such as providing public internet access, check cashing and notary services. The Senate bill also proposes to expand shipping alcohol through the mail.
“The main thing we wish now is that the Postal Service would do things to retain the customers that they have and even grow the volume of mail because it needs a certain critical mass to survive as the nation’s universal mail service,” said Stephen Kearney, executive director of the Alliance of Nonprofit Mailers, who worked at USPS for 33 years.
Kearney estimates nonprofit mail makes up to 10 percent of annual deliveries. But rising mail costs could lead some nonprofits to stop using mail for fundraising and other activities, further eroding volume, he says.
For Kosar of the R Street Institute, the federal government must adapt or risk losing one of its oldest communication networks.
“The public and Congress need to wake up to the fact that all signs point to the Postal Service being at a high risk of financial collapse,” Kosar said.

Ignore the talk comparing Shine to Rain Man, Awakenings and other mental-handicap snifflefests. Shine, based on the true story of the breakdown and recovery of Australian pianist David Helfgott, is scrappy, sexy, touching and fun. Audaciously directed by Scott Hicks from an unconventional script by Jan Sardi, Shine is also utterly extraordinary: biography without banality, uplift without upchuck, art without artifice. Rank it with the very best movies of the year.
In the first scene, the fortyish David, played by the remarkable Aussie stage actor Geoffrey Rush, stumbles out of a storm into a wine bar. His speech skitters about wildly as if his tongue can’t keep pace with his thoughts. To Sylvia (Sonia Todd), the bar’s owner, he’s a charming kook. When David sits down at Sylvia’s piano, he’s the virtuoso who was a star of the concert stage until 10 years before, when he suffered a breakdown after playing Rachmaninoff’s ball-busting “Piano Concerto No. 3.” Hicks, who tells David’s story in flashbacks, makes the duel between man and piano on the battleground of Rachmaninoff one of the most thrilling scenes in movie memory.
The childhood of young David, played by Alex Rafalowicz, reveals a prodigy prepped to take the world by his father, Peter (Armin Mueller-Stahl), a Polish Holocaust survivor whose own dream to shine, on the violin, has long been shattered. Mueller-Stahl, in a performance of lightning brilliance, is a marvel. Refusing to reduce Peter to a clichTd ogre, Mueller-Stahl shows how a father’s deep love for his son can be twisted by a deeper envy. When the teenaged David, vibrantly portrayed by Noah Taylor, defies his father and sets off to study in London with the great Cecil Parkes (a still-vital John Gielgud), Peter disowns him. The estrangement leaves David unhinged and at odds with the world outside of his music. Success on the concert stage soon gives way to a new role in life: mental patient.
After the wine bar, David picks up his life by marrying Gillian, an astrologer played by a frisky Lynn Redgrave. Their relationship, nurturing and teasingly erotic, frees David to return to the stage. Helfgott himself recorded the music. Rush, who is astounding, never smooths the edges off this wild eccentric. David rarely lights on dull earth, except to apply discipline to the keyboard. Even then, his inspired playing breaks the rules to take flight. Just like the movie. Shine, it does.

Sekisui House continues community engagement for its authentic new heart at Gledswood Hills
by Sekisui House on 06 09 2017 in The Hermitage
Gledswood Village at Gledswood Hills is a proposed mixed use retail, commercial, residential, entertainment and leisure precinct at the heart of The Hermitage masterplanned community. It is a modern interpretation of the classic high street much loved in Camden, and is designed to be intimate to create a sense of belonging.
Sekisui House senior development manager Brent Thompson said the concept for the precinct evolved from meetings with local residents and prospective tenants, from visiting a range of centres of varying scales and locations, and from extensive social and economic research. “We held focus groups and community consultation and what came out of that was that residents are looking for something different.
“They were yearning for sophisticated dining and cafe experiences.”
The proposed development will accommodate a range of uses, including, among other things, residential and commercial premises.
The residential buildings are proposed to include approximately 500 dwellings in a variety of housing types, including low rise terraces through to senior’s housing and apartment dwellings in mid-rise building of 3 to 5 storeys , primarily adjacent to the one of its kind Greg Norman designed par 3 golf course and driving range.
Mr Thompson said the new precinct has been designed to be pedestrian friendly, focused around a main street and intimate village square to promote social interaction and community wellbeing.
“It will be a vibrant precinct so there will always be something on. Our aim is to have activity from a reasonable hour of morning to a reasonable hour of night, giving the precinct the necessary vibrancy”
The site is adjacent to the future Gledswood Hills primary school so the precinct would also feature a childcare facility and a children’s playground.
Camden Council has recently resolved to publicly exhibit the strategic planning amendments, which commenced on Tuesday 5 September 2017.
The Sekisui House Team is facilitating a further series of community update sessions during September, 2017 to outline the current development plan for Gledswood Village and provide further background to the proposed strategic planning amendments.
The sessions will be held at The Hermitage Sales and Information Centre (Fairbank Drive, Gledswood Hills) over the following times.
Tuesday 12th September 2017, 6pm-9pm
Thursday 14th September 2017, 6pm-9pm
Saturday 16th September 2017, 8am-12 midday

Making her own path: Surry student completes 12 years in charter schools
Victoria “Tori” Fiorey knows a thing or two about charter schools.
The 18-year-old Surry resident recently graduated from Making Community Connections (MC2) Charter School-Monadnock in Keene, marking the completion of her entire education exclusively through public charter schools.
She started out as a kindergartner at Surry Village Charter School, which her mother, Matora Fiorey, helped found and who has been the director since its inception in 2006.
Tori was the first student to complete kindergarten through 8th grade at Surry Village, she said. And when it came time to decide where to go to high school, MC2 was just starting in Keene — so she opted to continue on the charter school path.
“When I went and ‘graduated’ 8th grade, as you say, it seemed unnerving to go to Keene High just because I had never been in a school over 100 kids,” Tori said.
At MC2, she enjoyed the freedom to come up with projects and research topics independently. But Tori said she sometimes struggled with self-direction and motivation to complete her assignments.
It’s a challenge she might not have encountered in the same way in a traditional high school, she said — and something she had to work hard to overcome. But she learned a valuable lesson, she said:
“The consequence of not doing your work is doing your work,” she said.
There are parts of the traditional high school experience she sometimes wonders if she missed out on — like prom and Friday night football games — but overall, she’s glad she opted to continue in charter schools. That’s because of the close relationships with teachers and sense of community she found, along with the opportunities to participate in internships, conferences and other types of real-world learning.
Tori is still deciding what she wants to do next, and for now, she is working part-time at Surry Village Charter School and continuing an internship she began while at MC2 working with horses at Meadowmere Farm in Vernon, Vt.
She doesn’t think college is the right path for her, but she might consider trade school or another path to a hands-on career.
“I like to do a lot of the hands-on work, so if I could do a job that just has me do apprenticeships and internships sort of deal — I really thrived in doing that hands-on kind of learning,” she said.
The Rindge Woman’s Club is offering three scholarships for Rindge residents for the 2019-20 academic year.
Two of the scholarships, each $1,000, are open to adult women who plan to return to school to gain new skills for employment or career advancement. The funds can be used for a certificate program, or for an associate degree, bachelor’s degree or master’s degree at an accredited institution. Preference will be given to women seeking an undergraduate degree.
The third $1,000 scholarship will be awarded to a Rindge resident who is studying plumbing or electrical trades. Adults or graduating high school seniors may apply, and the scholarship can be used for a full-time accredited program at a two- or four-year college or technical school.
The deadline to apply is July 31. Applications are available at www.rindgewomansclub.org. For more information, contact rindgewomansclub@gmail.com or Sarah Dengler at sarahjdengler@gmail.com.
Dublin Christian Academy student Abigail Johnson has been selected by the American Legion Auxiliary Post 5 to attend the Granite Girls State citizenship training program at Franklin Pierce University this month.
Participants are selected based on their leadership abilities, academic achievement and interest in government and current events. The program is open to girls who have completed their junior year of high school.
During the week-long experience, students from across New Hampshire will learn about how state, town and city governments work. They will elect their own town, city, county and state officials, hold a caucus and primary elections, and participate in a convention rally and general legislative sessions. They will also introduce and debate their own bills.
Two outstanding participants will be selected to attend the American Legion Auxiliary’s Girls Nation event in Washington, D.C., in July.
Three area educators were named Early Childhood Educators of the Year for the Monadnock Region by the Cheshire Children’s Museum and Impact Monadnock/Monadnock United Way. Siobhan Raymond of Jaffrey Head Start, Cindy Bechard of Friends-N-Fun Daycare in Marlborough and Linda Kinson of Keene Montessori School were honored on May 7 during a celebration for early childhood educators at the Keene museum.
The Keene High School Envirothon team took third place at the state Envirothon competition at NHTI in Concord last week. The team — Olivia Auger, Denali Croteau, Emily Fowler, Meredith Lewis, Elizabeth Parshall and Lindsey Walker — competed in four rotations in which they had to demonstrate their knowledge in forestry, soil science, aquatics and wildlife. They placed first in the aquatics and soils division.
The students also had to give a presentation on an environmental topic, and chose to research and present on advancing technology in agriculture. Twenty-two teams from across the state competed.
The team is advised by Keene High science teachers Monica Foley and Marshall Davenson.

England News
Croatia 0-0 England: Jadon Sancho shines but was it a missed opportunity for Ross Barkley?
England were held to a goalless draw by Croatia
By Nick Wright
Ross Barkley made his first appearance since 2016
England played out a goalless draw with Croatia in Friday's behind-closed-doors UEFA Nations League meeting in Rijeka, but what were the key talking points from the game?
Wasteful England held in Croatia
Sancho's spark
The buzz surrounding Jadon Sancho will grow even louder after his lively late cameo at the Rijeka Stadium. The 18-year-old became England's ninth-youngest debutant when he replaced Raheem Sterling in the 78th minute, and while he had to wait 10 minutes for his first touch, he still managed to make the most of his opportunity.
He showed his electrifying pace with his first contribution, latching onto a speculative through ball from Jordan Henderson and beating Josip Pivaric before his cross was blocked, and shortly after that he almost set up a late winner.
Pivaric was beaten once again, with Sancho then showing impressive composure to chip his cross towards the far post while running at full speed. If it wasn't for a fingertip intervention from outstretched Croatia goalkeeper Dominik Livakovic, his delivery would surely have been turned in.
Jadon Sancho comes on for his England debut
It was a continuation of his fine form for Borussia Dortmund, where he has contributed six Bundesliga assists in just 215 minutes on the pitch this season, and it will surely be enough for Southgate to consider using him again against Spain on Monday.
"He gave us a bit of excitement - getting the ball, being direct, trying to make things happen," said Sky Sports pundit Alex Scott. "He's shown no fear. He'll be in contention against Spain."
"There wasn't too much attacking excitement but it did seem to liven up a bit when Jadon came on," added Jamie Carragher. "He provided that bit of trickery out wide, that freshness."
Missed opportunity for Barkley?
Ross Barkley was handed his first England appearance since May 2016 as he joined Henderson and Eric Dier in Gareth Southgate's midfield. The 24-year-old has impressed for Chelsea under Maurizio Sarri this season, but could he carry his club form onto the international stage? Could he provide the creative spark England have lacked?
Barkley worked hard and improved as the game wore on, but there was little in the way of creativity. In fact, over the course of the 90 minutes, he did not fashion a single scoring opportunity.
The statistics showed he registered an 89 per cent pass completion rate, but few of those passes provided the penetration Southgate might have hoped for. In fact, more than half of them went backwards to Dier, Harry Maguire and John Stones. Barkley only passed to Sterling and Marcus Rashford three times each. He did not find Harry Kane once.
The lack of link play is a concern as England continue their search for midfield creativity, but Southgate will at least take heart from some of England's attacking work in the second half. The openings did not come from midfield, but on another night Rashford would surely have put one of his two one-on-one chances away.
Set-pieces were once again a source of danger, too, with Dier glancing a header against the outside of the post from a corner in the first half, and Kane sending another effort onto the crossbar from a free kick after the break.
Chilwell shines
Sancho was not the only youngster to get a chance, with Ben Chilwell making his first England start at left-back. The Leicester man produced an assured performance, defending solidly and showing impressive energy as he bombed up and down the flank.
Ben Chilwell impressed on his full debut
He showed his attacking threat with a string of crosses - the best of which came after 12 minutes when he collected a long ball forward and sent a wicked, low delivery into Croatia's six-yard box. Sterling was waiting to pounce, but Pivaric did well to scramble the ball clear.
"I thought he was excellent," Southgate told Sky Sports afterwards. "His defending was composed. He had some very good players up against him but he didn't dive in. His use of the ball was excellent and he showed good energy going forward. It's not easy in this final third to provide really high quality, but I thought he should be really proud of his performance."
Formation change
England enjoyed a great success with a back three during the World Cup, but Southgate insists he no longer sees it as a long-term option, with England reverting to a back four against Croatia. Crucially, however, Dier's presence in defensive midfield allowed him to drop into the defence when England were in possession.
"We've had success building with the three, and with Eric in that position it's perfect for him to drop into the back three," explained Southgate. "At times was the idea and there were other times where John and Harry just built the game themselves and Eric was a little more advanced.
Marcus Rashford missed two scoring chances.
"It meant we could get our full-backs a bit higher, so it's good to have that option, but definitely without the ball, it meant we were able to press higher and get closer to their midfield."
Carragher believes the flexibility will help England in the future.
Who are England's youngest debutants?
"A lot of people sometimes say it's not about formations, it's about players. I don't necessarily agree with that. Different formations give you different things. I think the beauty of that is that he saw the problem in three at the back not with the ball, but without the ball. So he doesn't want to change three at the back with the ball. So it gives him flexibility."

‘Bad Country’ Trailer: The Real Killer is Willem Dafoe’s Amazing Mustache
Posted on Monday, February 17th, 2014 by Russ Fischer
Films can get financing based on the attachment of a recognizable cast, and when a film’s director has previous credits producing known films, it makes it easier to bring elements together, whether or not the script is any good.
Chris Brinker makes his directorial debut with Bad Country, but he’s got producer credits going back to The Boondock Saints. And so he was able to bring in Boondock co-star Willem Dafoe to star in this cat and mouse story of a cop tracking down a killer. Also in the cast are Matt Dillon, Amy Smart, Tom Berenger, Bill Duke and Neal McDonough, not that any of it will probably matter. The first trailer for the film is pretty painful, but it has Dafoe looking mustachioed and haggard, and it’s worth the investment of a couple minutes just to enjoy his presence.
Bad Country will likely show up on disc media and digital platforms later this year.
Inspired by real events, BAD COUNTRY is a gritty Louisiana set crime drama. Detective Bud Carter’s investigations lead to the arrest of Jesse Weiland, a contract killer from a criminal syndicate. Weiland, facing life in prison and losing his family, puts his trust in Carter and becomes an informant. The case attracts the FBI, who in turn, wrestles control from Carter. When a sting goes bad, the syndicate boss, Lutin Adams uses crooked politicians and lawyers to identify Weiland as the ‘rat.’ His family is executed, setting Weiland on a path of revenge executing targets on a manhunt for Lutin. Carter takes control, pursuing the syndicate to the French Quarter. The climax explodes as Carter, Weiland and Lutin are caught in a triangular crossfire.

Market Structures In Computer Operating Systems
When purchasing a new computer the discussion on which operating system to choose does not usually come up, as there had been a monopoly in this industry since 1985 (Bellis, 2013). Microsoft with its Windows platform is a giant in the computer operating systems industry. The Microsoft Windows market structure began in an oligopolistic market, became a monopoly, and developed back into oligopolistic.
History – Early Years
In the early years of Microsoft Windows, the competition for computer operating systems was limited to MS-DOS, VisiOn, and GEM (Graphics Environment Manager). All of these systems struggled in a small demand market ...view middle of the document...
Instead of decreasing production, Microsoft windows made the decision to release a new version of their operating system to equalize marginal costs and marginal revenues.
History – Market Changes
On January 9th, 2007 Steve Jobs introduced the iphone and the introduction of Microsoft Windows competition (Bohn & Souppouris, 2013). As first introduced, the original iPhone and its operating system (iOS) was behind the Windows versions on feature-by-feature comparisons, but changed the market with new technologies. Originally designed for cell phone use, Apple’s iOS, with its pinch to zoom, touch screen capabilities, and full browser availability became so popular, that Apple released the ipad in April 2010 (Bohn & Souppouris, 2013). This ipad, along with a new iOS, was designed to compete with and possibly replace Windows as the most demanded computer operating system. This competition pulled some demand away from Microsoft Windows forcing them to change their strategy changing the market from a monopoly to an oligopolistic market.
Oligopoly Market
In this new market, Microsoft Windows is forced to engage in strategic decision making to continue its hold of the market share. Microsoft Windows in an oligopoly must take into account Apples iOS in its decision making. As of October 2013, iOS holds the largest market share for mobile and tablet devices at 55%, and Microsoft Windows holds the largest share for desktop operating systems at 91% (NetMarketShare, 2013). Being surpassed by iOS on mobile devices, Microsoft Windows must maintain its dominance in desktop and laptop computers.

William deVry DONE at General Hospital But Makes Fans A Promise!
0 0 Friday, 4 August 2017 Edit this post
Click here to read-->
William deVry's days at 'General Hospital' are done at least for now. The actor who attended the recent GH Fan Club Weekend gave fans an insight as to his situation at the ABC daytime drama. deVry was a bit late due to his audition for another gig. “I was auditioning for Taken on NBC for a recurring role, He’s a bad guy, surprise, surprise,” said deVry about his latest audition.
Though it was good news to learn that while we don't know how things will eventually work out with 'GH' and he's auditioning for other projects, deVry later gave fans the bad news. deVry confirmed that he and the show are yet to make a deal. He went on to say “My last day was June 30. I’m not greedy. It’s open ended. I’m auditioning a lot. We’ll see. I mean, I want to come back. Eventually.” The good part is there is still hope for the Julexis army out there as promised by the talented actor who's managed to be a part of 3 daytime soaps already. “There’s still hope, they set it up to where Julian could be gone for a little while or Julian could be gone a long while,” he told fans at the event.
Let's hope we haven't seen the last of Julian Jerome!

CollectiveSun, EnergySage partner to simplify solar process for nonprofits
By Kelly Pickerel | January 9, 2018
CollectiveSun, a company helping nonprofits and tax-exempt organizations fund solar projects, has teamed up with EnergySage to create a powerful new solution that allows nonprofits and tax-exempt entities to seamlessly navigate the solar purchasing and financing process.
The CollectiveSun-EnergySage partnership removes the hurdles that nonprofits and tax-exempt organizations have historically had in both financing solar installations and locating high-quality, pre-screened solar installers. Now, nonprofits and tax-exempt organizations will all be able to better take advantage of solar energy.
“CollectiveSun is always looking for ways to deploy more solar,” said Todd Bluechel, VP of marketing and sales for CollectiveSun. “The CollectiveSun-EnergySage partnership was formed to help broaden and strengthen both companies’ ability to deploy more solar. Even though this partnership is a win-win for both, it’s particularly beneficial for the 1.5 million nonprofits nationwide who have been seeking ways to afford solar.”
CollectiveSun provides a solar power agreement (SPA). This proprietary financing method allows the company to utilize solar tax benefits that would otherwise be lost and pass the savings onto the nonprofit buyer in the form of a 15% reduction in the cost of a new solar system. CollectiveSun also offers assistance and a variety of methods to help provide the upfront capital for the SPA, including a proprietary CrowdLending campaign.
This innovative financing model will now be available to nonprofits and tax exempt organizations that register on EnergySage. Backed by the U.S. Department of Energy, EnergySage is the country’s largest online comparison-shopping marketplace for solar, and matches thousands of nonprofits with its network of over 500 vetted solar companies each year. As validated by the National Renewable Energy Laboratory (NREL), EnergySage’s impartial information and competitive bidding platform helps solar shoppers make more informed decisions and save up to 20% on their solar installation costs.
“Installing solar panels is a great way for tax exempt organizations to reduce operating costs and simultaneously benefit the environment,” said Aaron James, VP of network partnerships at EnergySage. “Whether you run a school, food bank, church or other mission-based organization, the EnergySage-CollectiveSun partnership offers a new way to make an even larger impact by switching to clean, renewable energy. We’re up and running and actively accepting new registrations.”
To get started, nonprofits and tax exempt organizations are encouraged to visit www.collectivesun.com/installerbids. Organizations interested in offering a similar solution to its community should contact Aaron James at partnerships@energysage.com for more information.

Survivors of Tofino whale-watching incident sue tour company
German brothers accuse Jamie's Whaling Station of negligence after Leviathan II capsized last fall, leaving six dead
Laura Baziuk
Apr. 5, 2016 5:00 p.m.
The Leviathan II capsized off Vargas Island near Tofino on Oct. 25
Two passengers who survived a whale-watching boat capsizing off the coast of Tofino last fall, killing six people, have filed a potential class-action lawsuit against the tour company, alleging negligence.
The documents filed in B.C. Supreme Court last week provide new details on the devastating incident that shocked and saddened the coastal community known for its whale-watching industry.
Christian and Dirk Barchfield say they had been on vacation last fall when they booked a whale-watching tour on Oct. 25 with Jamie’s Whaling Station.
The two brothers from Germany allege Wayne Dolby, the captain, and two other crew members aboard the Leviathan II told the 24 passengers where the life-jackets were located and how to put them on, but that they were not required to wear them.
The Barchfields claim the sea was calm enough at the start, but high waves began to crest as the vessel reached open water.
The group caught sight of some whales going by and observed for about 45 minutes before the Barchfields allege the captain decided to navigate to a different location and the boat again moved into rough water with waves more than two metres high.
“At no point were the Plaintiffs or other passengers on the open deck advised by the defendant Dolby or other crew members to either put on life jackets or to keep them easily accessible.”
Christian Barchfield claims he “watched the high waves crashing against the window and felt very uncomfortable and afraid,” while his brother alleges the crew did not demonstrate any concern about the sea conditions.
At this point, the brothers claim the vessel “tipped violently to the left and capsized.”
Dirk Barchfield claims he clung to a life ring with several other passengers while being hit by the high waves, while Christian was trapped in the lower, indoor deck, being “thrown about as though he were in a washing machine.”
Eventually, a fishing boat arrived and two men from the Ahousaht First Nation called in other boats and helped pull the survivors out of the water.
The brothers were hospitalized and treated for cuts, bruises, scratches, hypothermia and severe shock.
Six people did not survive, all from Britain, including an 18-year-old boy who’d been celebrating his birthday on a family trip.
The Barchfields are seeking general, special and punitive damages, accusing the defendants of negligence because they knew or ought to have known it was unsafe to go out in those conditions.
None of the allegations has been tested in court and a statement of defence has not been filed.
At the time of the capsizing, tour company owner Jamie Bray said the boat had made that trip all the time and that Dolby had 20 year’ experience, with the crew going through safety drills every two weeks.

Kawhi Leonard free agency rumors: Lakers believe they’re 'firmly in the lead'; Drake plans Raptors pitch
Written By E.Jay Zarett
(Getty Images) https://images.performgroup.com/di/library/omnisport/4a/46/kawhi-leonard-usnews-060719-ftr-gettyjpg_1lpmpzqit0to913451y1i4fdi9.jpg?t=887834323&w=500&quality=80
height="148">
The Lakers think they have a strong chance to add Kawhi Leonard, but another Toronto star isn't giving up just yet.
Per The New York Times, Raptors superfan Drake "is said to be mounting his own recruiting campaign on top of whatever the freshly minted champions are doing to convince him to stay."
Hard to say what impact Drake might have on the low-key superstar, but it's worth noting.
Still, the Lakers believe they're "firmly in the lead" to land the star because of the "recruiting efforts and assurances made on separate fronts" by some high-profile pitchmen, too: former president of basketball operations Magic Johnson and LeBron James, according to the Times.
Kawhi Leonard's decision is 'franchise-changing,' Raptors' Fred VanVleet says

NBA free agency rumors: Raptors chances of keeping Kawhi Leonard are 'fading'
1. The Lakers, as we've been saying for more than a week now, believe they are firmly in the lead largely through the recruiting efforts and assurances made on separate fronts from Magic Johnson and LeBron James ...
- Marc Stein (@TheSteinLine) July 2, 2019
Leonard was sent from the Spurs to Toronto in a blockbuster trade last summer and he almost single-handedly carried the team to its first title in franchise history.
Leonard averaged 30.5 points in the playoffs, was named the Finals MVP and helped the Raptors avoid elimination by knocking down a crazy bouncing buzzer beater in the fourth quarter of Game 7 against the 76ers in the second round.

- Toronto Raptors (@Raptors) May 13, 2019
Leonard is reportedly reconsidering returning to Toronto, while the Clippers are in the mix to sign him, as well.
The Lakers, meanwhile, acquired Anthony Davis from the Pelicans last month in exchange for Brandon Ingram, Lonzo Ball, Josh Hart and three first round picks. They then cleared cap space to sign a third star to pair with Davis and James when they dealt three bench players to the Wizards last week.
Davis also reportedly waived his $4 million trade kicker so the Lakers could have more flexibility.
"My goal is to win a championship," Davis told the Los Angeles Times earlier this week. "I expect to win every time I step on the court, every game. I want to win a title. That's what it's about - winning titles. That's the only thing on my mind."
Los Angeles also agreed to a one-year deal with Troy Daniels, according to multiple reports. He has connected on 40% of his 3-point attempts over 292 NBA games.

Hitting Skills with the Cleveland Indians
By Josh Staph
The Cleveland Indians began the 2005 season in dismal fashion, kind of like their big screen counterparts in Major League. The only thing missing was "Wild Thing" Rick Vaughn on the mound.
On June 5, the Indians were dead last in the AL in runs scored, batting average and on-base percentage. It was as if the Tribe's offense was under the curse of Jobu.
The crack of the bat and the roar of the crowd are two sounds that Cleveland Indians hitting coach Derek Shelton loves to hear. Learn from this maestro how to get the bat off your shoulder to make sweet music at the plate.
Instead of sacrificing a live chicken, the Indians made hitting coordinator Derek Shelton their hitting coach. For the remaining 108 games of the season, the Tribe posted a league-best average of .285 at the plate. At the end of the regular season, the Indians were fourth in the league in runs scored (790), fifth in batting average (.271) and third in home runs (207).
Here are the instructions and drills that turned the Tribe into pennant contenders.
ELEMENTS OF THE SWING
According to Shelton, young hitters need to realize that maintaining balance throughout the swing is the most important element. "Good balance starts when you set up your stance and continues until you finish the motion," he says.
Differences in body type compel players to find comfort and balance individually. "We have guys who distribute their weight 50-50, some 60-40 and others who start 70-30," Shelton says. "It doesn't matter as long as you're comfortable and balanced. However, the common element in all good hittersfrom Little Leaguers to pros like Travis Hafneris that when their front foot hits the ground from the stride, their weight is on the inside of their back knee."
Test Your Stance
Assume your batting stance, then have someone give you a good push on the chest or from the side. "If you are in a good, balanced position, your feet won't move," Shelton says.
Head Position
As elementary as it sounds, keeping your head down is crucial. Shelton explains, "The tendency for young hitters is to try to hit the ball too hard. They end up pulling their head off the ball. When that happens, their shoulders and hips come off the ball too, since the head leads them. Concentrate on keeping your head down to alleviate these problems."
Hands In Launch Position
"Your hands have to be in a strong launch position when you start your swing," Shelton says. "This position is different for each guy. And it doesn't matter if you set up with your hands in position or move them there when you start to swing. You just have to make sure that is where your hands come from."
To find your personal launch position, follow Shelton's guide:
Stand at the plate.
Hold the bat loosely in your fingertips with your arms forming a "V" and the bat pointing down the first base line (third for lefties).
Swing the bat toward the backstop, like you are taking a backswing with a golf club.
Stop the bat at the furthest position back. That point is your strongest positionand your launch position.
Even at the Major League level, hitters focus on fundamentals on a daily basis. Shelton says, "I think the best way to prepare all hitters is to develop a daily routine based on fundamentals. Each guy does something different, but all of them work on honing their craft and maintaining fundamentals."
The following routines are done in the cage or on the field before a player takes batting practice. "High school hitters usually just want to go out on the field and hit," Shelton says. "But first you have to nail down the fundamentals in a controlled environment. If we're in the batting cage and I'm tossing balls underhand to a guy 15 feet away, I can control the speed and placement of the ball, and he can control the barrel of the bat, because things are slower and under control. This is when teaching and interaction take place."
Once the Tribe takes the field for BP, they focus on hitting the ball hard (not necessarily aiming for the fences) and getting the barrel of the bat on the plane of the ball. At that point, it is about their bodies reacting and putting everything together.
Develop a daily routine with these fundamental drills.
Place tee on inside of plate and another on outside
Assume balanced batting stance with hands in launch position
As you begin swing, coach calls "inside" or "outside"
React with hands to hit appropriate ball
Shelton Says: "It is sometimes hard to get younger players to hit off a tee, because they think it's only for kids; but our guys work off the tee a lot.
"Begin with one tee in the middle of the plate. If you can't master hitting a ball in the middle of the plate, you're going to have some trouble; it is the best pitch to hit.
"The reactive aspect of this drill eliminates a player's tendency to predetermine where he is going to swing. He doesn't know where a pitch is going to be when he bats in a game, so teaching him to react to ball placement is key. This also improves plate coverage, because players get used to making contact on the inside and outside of the plate."
Without a bat, assume balanced batting stance with hands in launch position
Hold baseball in top hand
Swing and release ball at point of contact
Shelton Says: "Focus on releasing the ball so you throw it directly in the middle of the field. This indicates that you are bringing your hands through the correct bat path. If you release the ball to the right, you are not bringing the bat through the ball. If you release it to the left, you are bringing the bat across the plate and not maintaining a strong position.
"The key here is to work at being short to the ballgetting the barrel of the bat to the hitting zone as quickly as possibleand then keeping the barrel there as long as possible. Imagine you are swinging so your bat skims a tabletop. Focus on making your bat glide across the table as long as possible, just like you should try to keep your bat on the plane of the ball. This is what makes Centerfielder Grady Sizemore such a good hitter. He has the unique ability to get his bat there quickly, and then keep it there so he can work through the ball.
"In effect, you are driving the ball through the middle of the field. The ball's direction is dictated by where you hit it and what kind of contact you make, but driving through the ball makes for a harder hit."
Slump Buster
Stuck in a slump? Shelton has the solution. "When a guy is struggling at the plate, we look at what causes the slump," he says. "At the Major League level, it's usually the result of pitch selection, or how opposing pitchers attack him as a hitter. Strategy and mental preparation help get these hitters out of a slump.
"The situation is different at the high school level. High school players usually hit a slump when their swing fundamentals break down. This is why it is so important to know your swing and stick to your routine."

These newly unearthed pictures give a rare glimpse into Sheffield's smog-filled industrial past.

Smog-filled city. Picture: Estate of Jack Corbey
The images are from a collection believed to span from the 1930s to the 1950s.
Some of the pictures are said to illustrate the construction of the original Co-operative store on Castle Hill and Castle Market between 1928 and 1930.

Ms Corbey explained that they had been found in family archives and had belonged to her late father-in-law Jack Corbey, who found time to take the snaps while working as an electrician at the site.
During building work it is believed they discovered remains of the former medieval Sheffield Castle, which was destroyed at the end of a Civil War siege in the 17th century.
The unearthing of the pictures is also timely as excavation work by archaeologists got under way at the Castlegate site this week in a bid to discover more about both the castle and the site's later industrial past.
Workmen at Castlegate. Picture: Estate of Jack Corbey
"The clocktower of the Old Town Hall on Waingate can be clearly seen on two of the rooftop images, as can buses or trams on Lady's Bridge with Tennants brewery and the chimneys lining the River Don in the direction of Kelham Island below.
"We are hoping readers might be able to identify some of the workmen on the photographs."
Just a decade after opening, the flagship Co-operative store was badly damaged in the Blitz in 1940.
Castlegate. Picture: Estate of Jack Corbey
A new department store was opened in nearly Castle House in the early 1960s.
Ambitious plans have recently been revealed to open a food hall inside part of it and for other floors to be used as a hub for digital businesses.
Castle Market was demolished in 2016 which paved the way for the archaeological dig started this week.
The old clocktower. Picture: Estate of Jack Corbey
Initial plans are being drawn up for the future of the old market site, which is set to include more green areas as well as pedestrianised zones.

Public funds for predator control?
The RSPB in Scotland has lent its support to the idea that predator control should form part of Government-funded conservation.
At a conference last month on the future of Common Agricultural Policy (CAP) funding, the idea that predator control options should be more widely available as part of conservation ?bundles? was broadly welcomed.
When asked about this aspect of the conference, director of RSPB Scotland Stuart Housden, who attended the event in Perth, told Shooting Times: ?There is growing evidence that legal predator control will help the recovery of some groundnesting birds, though predator control alone is no substitute for targeted habitat management for scarce birds such as capercaillie, blackgrouse and waders.?
Dr Adam Smith, director for Scotland at the Game & Wildlife Conservation Trust (GWCT), who was also at the meeting, concurred that predator control should be carried out not in isolation but as part of a package of targeted measures. He said: ?Among the many topics discussed, there was a strong feeling that predator control should be more widely supported. However, predator control alone may not be effective ? one could say that, no matter how many crows are killed in a car park, you won?t get lapwings to nest on tarmac.?
The rest of this article appears in the 18th April issue of Shooting Times.

Are Fireworks Legal in Colorado?
Colorado Legal Defense Group
Colorado Fireworks Laws
Colorado fireworks laws vary depending on your city or county. In some areas -- including Denver, Fort Collins, and Lakewood -- fireworks are totally illegal.
The illegal use of fireworks in Colorado can cost you as much as $2,750 in some jurisdictions. It can also land you in jail for a year. You could end up with a criminal record -- just for being patriotic.
In some parts of Colorado, certain types of fireworks are legal, but most are not. Illegal fireworks include those that are airborne or which explode or fragment. Examples of illegal fireworks include bottle rockets, cherry bombs, M-80's and Roman candles.
To help you better understand Colorado's fireworks laws, our Colorado criminal defense lawyers discuss the following, below:
1. What fireworks are illegal in Colorado?

Fireworks that explode or leave the ground are illegal everywhere in Colorado. These include fireworks purchased in neighboring states (such as Wyoming).
Illegal fireworks in Colorado include (but are not limited to):
firecrackers,
cherry bombs,
bottle rockets,
mortars,
M-80's, and
Roman candles.
And even fireworks that are otherwise legal under Colorado state law are prohibited in:
U.S. national parks (including Rocky Mountain National Park and Gunnison),
Colorado state parks,
local parks,
golf courses,
city streets, and
most other public spaces.
Where permissible under local law, legal fireworks in Colorado consist of small devices that produce audible or visual effects (but not explosion) through combustion. Each class of permissible fireworks has a different upper limit on the maximum amount of explosive material a device may contain. However, no home fireworks device may contain more than 50 milligrams of explosive composition.
If permitted under local law, legal fireworks in Colorado include the following:
fountains,
toy caps,
snake or glow worms,
ground spinners,
illuminating torches,
dipped sticks and sparklers,
toy propellants,
noise makers that crackle or whistle (but don't explode), and
certain tube devices.1
Local regulations vary by location and from year to year, depending on drought conditions. Accordingly, it is best to check with your local law enforcement agency or fire department before purchasing or using fireworks. See Section 5, below for a list of current Colorado fireworks laws in specific jurisdictions.
Possession of illegal fireworks is a Colorado class 3 misdemeanor.
Consequences of possessing illegal fireworks in Colorado range from a minimum $50 fine to a maximum of:
A fine of $750, and/or
Up to six (6) months in jail.2
Local laws, however, often impose harsher penalties. For instance, in Denver, setting off fireworks of any kind is illegal. Consequences of fireworks use or possession in Denver and many other cities can include penalties of:
A fine of up to $1,000, and/or
Up to one year in jail.
It is unlawful in Colorado to furnish fireworks to anyone under 16 years of age. Those under 16 are also prohibited by law from buying fireworks in Colorado.
If permitted under local law, however, children under 16 may use otherwise legal fireworks under adult supervision.3
The following list is subject to frequent changes depending on weather conditions. Before purchasing, possessing or using fireworks in Colorado, check with your local law enforcement or fire agency to determine if such use is legal.
Note that in unincorporated areas of the state, it is generally legal to use Colorado permissible fireworks on private property.

5 Lawyers are supposed to have a bad name, but the Colorado Legal Defense Group exhibited service, insights, and class that should make anyone feel very confident in calling upon their aid. I had an emergency legal case come up and Colorado Legal Defense Group looked like they had a specialty in this area. One of the lawyers (a 19-year veteran of the Denver PD as Lieutenant, whose experience there was helpful) answered the call at about 10pm on a Sunday night, and reassured me on the situation. During the week I spoke with another lawyer on staff – 3 people all told during the week. They were very detailed about my situation and the possible outcomes. When the DA announced his office would not be pressing charges, the Colorado Legal Defense Group tore up the check I had written them because they didn't have to dig in and represent me in court. So the week's worth of communication ended up being gratis. Most appreciated! Todd R.

Serena Williams Stands Firm On "Fight For Equality" Following Wimbledon Loss
Blac Chyna Opens Up About Kylie Jenner & Tyga’s Relationship On Wendy Williams Show
A few weeks after vowing to be a better person, Blac Chyna has not only dropped off a trailer for her upcoming reality show (as seen below) but she’s also paid a visit to The Wendy Williams Show to discuss her baby father, Tyga.
Blac took Wendy back to the days when she was with Tyga and how she knew their relationship was over when he kicked her out of his mansion to be with the then 17-year-old Kylie Jenner. Wendy asked Blac how she knew that Tyga had linked with Kylie at the time where she detailed how she didn’t see them kissing but knew “they were definitely together.”
“The way it went about publicly wasn’t right. Even not publicly it wasn’t right,” Blac said of the drama with the family. “So Tyga started dating Kylie, after that happened, that’s when, of course, the family was like, ‘Well, bye girl’ and threw me underneath the bus.”
As for Blac’s series, the mother of two told Wendy that she’s trying to get her mom, Tokyo Toni on board for the show (who she’s had lots of drama with) as well as Rob Kardashian. The show will premiere this summer on Zeus.

Health insurance rates skyrocket for middle-income consumers
By Ron Hurtibise
Some analyst fear increased 2018 costs for health insurance consumers ineligible for federal subsidies could signal the beginning of the so-called "death spiral" for Obamacare. This file photo was taken at an Obamacare signup location in 2015. (Joe Raedle / Getty Images)
Health insurance consumers who rely on Obamacare plans but make too much money to qualify for federal subsidies are in for unpleasant surprises during the 2018 enrollment period that begins Wednesday.
Premiums are up, deductibles and out-of-pocket caps are higher, and provider networks are smaller for the most affordable plans, according to insurance agents and industry analysts.
Consumers affected worst include working-age individuals who expect to make more than $48,240 next year and don’t qualify for employer-based insurance.
In that group are small business owners, early retirees with lucrative investment incomes, real estate sales reps, accountants, insurance brokers, some doctors and nurses, accountants and bookkeepers, and other independent contractors.
Many have health issues, require care, and will pay whatever it takes to secure guaranteed coverage that will keep their 2018 health care costs from spiraling into tens or even hundreds of thousands of dollars.
[More business] Port Everglades employees face federal charges in fraud investigation »
Premiums for plans that provide coverage required by the 2010 Affordable Care Act are up sharply — an average 44.7 percent statewide according to the Florida Office of Insurance Regulation.
That number is a bit misleading, as it includes 31-percent mandated rate increases for “on-exchange” Silver plans sold to subsidy-eligible low-income consumers that middle- and upper-income consumers are unlikely to choose.
The 31-percent rate increases were imposed to offset the loss of federal payments directly to insurers. Qualifying low-income consumers will still get the same discounts off premiums, deductibles and copays, but from another federal funding source.
That’s no comfort to higher-income consumers about to find out the cost of their unsubsidized plans are heading up. Excluding the 31-percent mandated hikes, companies requested 2018 rate increases averaging 18 percent.
And gone are the days of affordable plans with low deductibles and out-of-pocket caps. These days, consumers who want to keep monthly premiums below $600 are confined to narrow-network plans or deductibles and out-of-pocket limits of around $7,000.
Most consumers who don’t qualify for subsidies buy “off-exchange” plans directly from insurers, through brokers or agents, or from private-market exchanges not run by the government.

Of 1.45 million purchasers of individual health insurance plans in 2016, about 214,000 bought full-rate plans outside of the Healthcare.gov exchange, according to an annual tally by the Florida Office of Insurance Regulation released in July.
Agents who sell plans for Florida Blue, the largest insurer in the state, were told in September that plans not subject to the additional 31-percent hike would increase an average 12 to 14 percent.
AvMed, one of just two remaining companies in the South Florida region that sell off-exchange plans with wide provider networks, was approved for rate increases averaging 38.7 percent.
AvMed had 54,340 enrollees in its individual HMO plans in the second quarter of 2017, according to state data.
Boca Raton agent Gary Warren is advising clients facing steep increases for AvMed policies to find an agent who sells Florida Blue policies.
One of his clients, a 62-year-old enrolled in an AvMed health savings account plan that was discontinued, was notified her monthly premium would increase from $639 to at least $1,153 if she wanted to remain with the insurer, he said.
[More business] Shake Shack to open at Sawgrass Mills »
“Last year, AvMed was the affordable selection,” Warren said.
In a statement, AvMed spokesman Corey Miller said health insurance pricing is “an extremely complex formula that reflects the rising cost of providing coverage in an increasingly unpredictable market environment.”
“The challenge is universal and many carriers have responded to it by withdrawing completely. AvMed chose to stay and we continue to offer consumers what we believe is a high value option that remains very competitive,” Miller said.
If most of Warren’s AvMed clients switch to Florida Blue, they won’t be alone. The company said it absorbed thousands of clients in 2017 left stranded by companies that pulled out of Florida’s individual market, including UnitedHealthcare, Humana, and Aetna/Coventry.
Today in South Florida, just three companies are selling on the exchange — Florida Blue, Molina and Ambetter.
Florida Blue also created 12 new off-exchange Silver plans for consumers who don’t qualify for subsidies with prices comparable to what they would have been on-exchange before the 31-percent increase mandate. Florida Blue has been contacting about 66,000 of its on-exhange Silver plan customers who don’t qualify for subsidies and urging them to avoid the 31-percent increase by choosing one of the new off-exchange plans.
[More business] Celebrity Cruises maitre d’ awarded $10.3 million for injury in kitchen »
Molina and Ambetter are narrow-network on-exchange options that were affordably priced in 2017 but are also raising rates for 2018.
Molina’s rates are up an average 71.2 percent while Ambetter’s are up 46.1 percent. Both increases include the 31-percent subsidy offset.
Another factor contributing to rate increases this year was uncertainty over whether the Trump administration planned to continue levying tax penalties for individuals who did not comply the Obamacare requirement to maintain health insurance.
After Donald Trump signed an executive order calling on his administration to freeze Obamacare regulations, the Internal Revenue Service said it would not enforce the requirement. In August, the IRS reversed itself and said 2017 tax returns that did not include answers to the question, Do you have health insurance, would not be processed.
Obamacare advocates fear more people will remember Trump’s order than the IRS’ reversal, said Gary Claxton, a health care policy researcher at the non-profit Kaiser Family Foundation.

Without the individual mandate requiring young, healthy people to buy health insurance — and paying premiums used to treat older, sicker people — costs for those who remain in the pool will increase beyond the market’s ability to sustain itself, analysts say.
In addition, advocates are concerned that young people will turn to lower-cost association health plans that don’t offer the same level of coverage as plans that comply with ACA requirements. Such plans, common before the ACA, can be priced based on the insured’s health status and can be discontinued if that status changes, Claxton said.
Cliff Eserman, a Wilton Manors insurance broker, says he fears 2018 could be the final year of Obamacare.
“You’re still going to see people on it, but the death spiral is in place,” he said. “Healthy people are not going to pay $1,000 a month.”

Tempe Police: Man denies having weapon in car, police still find it
Photo by Austin Bailey | The State Press
The Tempe Police station, which is located on Fifth Avenue near College Avenue.
By Isabella Castillo | 11/04/15 3:31am
Tempe Police reported the following incident Tuesday:
A Phoenix man was arrested Oct. 25 on South Hardy Drive and Southern Avenue on suspicion of drug possession and misconduct with a weapon, according to a police report.
An officer pulled a car over where the man was a passenger, and asked if the vehicle contained any drugs or weapons, police reported. The men denied that there was anything illegal in the car multiple times, but the response made the officer uncomfortable, according to the report.
A background check revealed that the man had a warrant from the City of Phoenix, and the officer informed him that he would be arrested, police reported. The man then admitted to having a weapon under his seat, according to the report.
While searching the vehicle, officers found the gun, marijuana and grape swisher sweets, police reported.
In an interview, the driver told officers that the marijuana belonged to the man and claimed that the man was a marijuana dealer whom he had only met recently, according to the report.
The man told officers he smokes weed at least once a day and carries the gun "just because," police reported.
The man was transported to Tempe City Jail, where he was booked and held to see a judge, according to the report.

China calls any challenge on Taiwan ‘extremely dangerous’
Defence minister Wei Fenghe warned that it is "extremely dangerous" to repeatedly challenge China’s bottom line in territorial matters.PHOTO: AFP
Oct 25, 2018, 9:45 am SGT
http://str.sg/oh8Z
BEIJING (BLOOMBERG, REUTERS) - China’s defence minister warned that any effort to challenge its authority over Taiwan was “extremely dangerous,” following recent US moves that signalled greater support for the self-ruled island.
General Wei Fenghe was speaking at the start of the Beijing Xiangshan Forum, China’s answer to the Western-dominated Shangri-la Dialogue held annually in Singapore. He also called on American leaders to drop what he said was a “Cold War mentality.”
His speech came just days after the US Navy sailed two warships through the Taiwan Strait, in the second such show of military support since July.
“Taiwan is China’s core interest,” Wei said. “On these issues, it’s extremely dangerous to challenge China’s bottom line repeatedly. If anyone tries to separate Taiwan from China, China’s military will take action at all costs.”
Taiwan has reemerged as a flashpoint in US-China relations as their trade spat aggravates a host of security disputes between the two sides. China has repeatedly protested US moves to bolster ties with Taiwan, amid a spat between Beijing and the island’s pro-independence government that took power after a 2016 election.
In recent months, the US has signalled a broader push back against China’s growing military reach in the region, with President Donald Trump vowing to outspend it in an arms race after his decision to withdraw from an anti-missile treaty with Russia.
The US has also criticised what it says are Chinese efforts to “militarise” outposts it has built on reclaimed land in the South China Sea, by building bases and deploying missile batteries.
Sea Disputes
Wei, who met US counterpart Secretary of Defence James Mattis at a regional security meeting Friday in Singapore, said military facilities were needed to protect Chinese interests in the South China Sea. Destroyers from the two navies nearly collided in the area last month during a US “freedom-of-navigation operation” to challenge what it says are illegal territorial claims by China and its neighbours.
“The South China Sea situation is stabilising, which proves that all countries can take care of their own affairs,” Wei said. “China opposes countries that come to the South China Sea from outside of the region in the name of freedom of navigation to show force and provoke, which leads to rising tensions.”
Mattis told his Chinese counterpart last week that the world's two largest economies needed to deepen high-level ties so as to navigate tension and rein in the risk of inadvertent conflict.
Mattis saw firsthand last month how mounting Sino-US friction can undermine military contacts, when Beijing upended plans for him to meet Wei in October.
China has been angered by the US sanctions on its military for buying weapons from Russia, and by what Beijing sees as stepped-up US support for democratic Taiwan, which it claims as sacred territory.

US concerned about China's pressures on Taiwan and in South China Sea: Defence official
China has also expressed concern after US President Donald Trump said Washington would withdraw from a landmark Cold War-era treaty that eliminated nuclear missiles from Europe because Russia was violating the pact.
China is not a party to that treaty, but Trump has also suggested Beijing’s military strength played a role in his decision, which China has described as “completely wrong”.
The minister said China had no interest in engaging in an arms race. He also denounced Trump administration claims that the Chinese government was attempting to meddle in the US midterm elections, saying the accusations had “severely damaged” ties.
“It has been proven that a hegemonic and confrontational security model is outdated,” Wei said. “The world shouldn’t repeat the Cold War. All countries should respect each other’s sovereignty, security and development rights.”

4 hurt in flyover accident; buses, cars stuck in jams

An accident involving a taxi and a van left four people injured and caused delays of around two hours yesterday morning.
The Singapore Civil Defence Force was called to the Toa Payoh North flyover - near Toa Payoh Lorong 6 - at 8.15am.
Four people - including the ComfortDelGro cab driver and his two passengers - were taken, conscious, to Tan Tock Seng Hospital.
The accident involving a taxi and a van (centre) on the Toa Payoh North flyover yesterday morning left four people injured, including the cab driver and his two passengers. Buses were stranded back to back, and there were jams along Braddell Road, while several nearby roads were closed temporarily. Eight SBS Transit bus services had to skip bus stops along Braddell Road and Toa Payoh Lorong 6. ST PHOTO: JAMIE KOH
The taxi appeared to have come off worst in the accident, with its front part crushed.
At 10am, there were still about a dozen SBS Transit buses on the flyover, lined up back to back. Passengers were seen alighting and walking along the flyover.
The accident caused jams along Braddell Road, and several roads nearby were closed temporarily by the Traffic Police. Eight SBS Transit bus services had to skip bus stops along Braddell Road and Toa Payoh Lorong 6 as a result.
Some bus drivers were told via their intercom system to divert and avoid the flyover.
Some passengers were told to alight earlier if the buses could not get to their intended stops.
Ms Wendy Gao, 28, who teaches in the afternoon session at a school in Toa Payoh, said the bus she was on was diverted."It's my first time being stuck in a situation like this. It was smart of the driver to change the route to avoid the flyover.
"I use mobile apps to check bus arrival times and they are sometimes inaccurate. It'd be good if alerts about such jams or route diversions could be sent out."

TFS hosts community event for Tallulah Falls police chief
In the spirit of community partnership, Tallulah Falls School hosted a special event for the town of Tallulah Falls on Feb. 5. The late afternoon reception to honor Tonya Elrod, the newly appointed chief of police for the town also served as an occasion to hold a ceremonial swearing-in.
More than 100 people attended the event including family, friends, town, school and other government officials joined by a strong showing by the public safety community. Representatives from the business community including Georgia Power and Tallulah Falls State Park were also in attendance.
“We were delighted to host this event to welcome Tonya to Tallulah Falls,” said President and Head of School Larry A. Peevy. “We enjoy a collaborative town and gown working relationship with our partners in Northeast Georgia. We know Tonya will be an asset to our community.”
Peevy welcomed the crowd and made a few remarks about the history and success of the school.
Tallulah Falls Mayor Teri Dobbs introduced Elrod before inviting Mountain Judicial Circuit Superior Court Judge B. Chan Caudell to administer the oath to Elrod.
“Tonya's experience, leadership qualities and compassion for all are tremendous qualities that will enhance our town while building on the history of retired police chief Bill Goatcher’s 21 years of service,” Dobbs said. “It is evident by the crowd that we made the right decision.”
Elrod, sworn in officially on the day after being appointed, made a few remarks to the group emphasizing her desire to continue to build on established relationships.

Nadal and Pliskova Claim Italian Open Titles
May 19, 2019 by Tennis Panorama News
(May 19, 2019) Rafael Nadal and Karolina Pliskova earned singles titles at the Italian Open on Sunday.
For world No. 2 Rafael Nadal, after losing the semifinals of the last three clay court events, the Spaniard is finally in the winner’s circle for 2019 earning the Rome crown with a 6-0, 4-6, 6-1 win over No. 1 Novak Djokovic. The title for the 17-time major winner is a record-setting ninth Rome title, also giving him the record for Masters 100 events with 34, one ahead of Djokovic. He now has a total of 81 career titles.
For the Czech Pliskova, she earned her second title of the year with a 6-3, 6-4 win over Johanna Konta of Great Britain. The fourth seed won the Brisbane title back in January. Pliskova will move up to No. 2 in the world when the new rankings come out on Monday.
“Finally I have a title,” Nadal said to media after the match. “Here we are. Important title, important moment.”
“I played a great first set in all aspects,” Nadal said of his first-set bagel against Djokovic. “No mistakes. Playing so aggressive, changing directions.”
“It’s not usual and probably will not happen again.”
“Winning a title is important but for me the most important thing is feel myself competitive, feel myself healthy,” Nadal said.”
“Rafa was simply too strong today,” Djokovic said on court.
“I was just running out of fuel a little bit today,” the Serbian said to media during his news conference. “Just kind of missed that half a step, especially on the backhand side.”
“What means most to me is this trophy,” Nadal said of the Internazionali BNL d’Italia. “Rome is one of the most important tournaments of the year. [It’s a big] part of the history of our sport. To be able to win here again is the main thing.”
Nadal heads into the French Open next Sunday aiming to win his 12th title in Paris.
As for Pliskova, this was her 13th career WTA title.
“I just hope to take the tennis I was playing here to Paris,” Pliskova said after the match. She admitted that she felt that no one gave her a chance to win Rome, not even herself. “For sure there’s going to be a chance for me if I play this way.”

Richard Hamilton
Stage Proof 11
© The estate of Richard Hamilton
Richard Hamilton 1922–2011
Release Stage Proofs
Screenprint on paper
Presented by the artist 1977
Release – Stage Proofs 1-13 and 16-19 (P02416-32; the series is incomplete) is a group of seventeen prints showing the process of building up colour to make the print Release (P04254). Each proof represents the successive addition of a screen, made from a hand-cut stencil, used to apply a particular colour. The completed print Release combines the seventeen colour screens, each used once, and the photographic black screen which has the texture of an imprint on canvas as well as the photographic halftone, used twice.
The print Release derives its title from the name of an organisation set up to provide legal aid and social support to people who have fallen foul of the law, often as a result of drug abuse. In 1972, Diana Melly (married to the jazz musician, writer and critic George Melly and working for Release) asked Hamilton if he would make a print to help raise funds for the organisation which was in financial difficulties. The artists Jim Dine (born 1935) and David Hockney (born 1937) also contributed, deciding to divide the profits between Release and the National Council for Civil Liberties. Because of the focus of Release on those suffering from drug abuse, Hamilton decided to use one of the images he had created in his Swingeing London group of works. These were generated by the arrest and imprisonment of Hamilton’s art dealer Robert Fraser (1937-86) in 1967 for the possession of heroin. The artist had created a poster from a collage of press cuttings from the event entitled Swingeing London 67 – poster, 1967-8 (P01855), before embarking on a group of seven paintings entitled Swingeing London 67 1968 (private collection) and Swingeing London 67 (a) – (f), 1968-9 (Swingeing London 67 (f) is T01144).
The Swingeing London paintings are all based on the same image – a photograph of Robert Fraser and the rock star Mick Jagger in a police van being taken from jail to court. The photograph, taken by John Twine, was published in the Daily Sketch newspaper on 29 June 1967 and shows the two men, handcuffed together, trying to shield their faces from the press photographers. Hamilton had come across the image in the collection of press cuttings Fraser’s secretary had given to him when he was creating the print Swinging London 67 – poster and he placed it at the top left corner of the composition. In order to use the image to make an etching (Swingeing London 67 – etching, 1968) Hamilton purchased a ten by eight inch print of the whole of Twine’s photograph from the Fleet Street offices of the Daily Sketch. He extended the picture on all four sides, revealing a police guard on the left and second van window on the right. The image was also enlarged up and down, showing the curve of the roof inside the van and more of the prisoners’ chests than had been previously visible. He retouched the photograph to remove the outside of the van and the overlapping glass of the sliding window that cut vertically through the centre of the image. After making these alterations, Hamilton planned to silkscreen the resulting photographic image in black over a coloured, conventional oil painting. As this involved extensive experimentation, Hamilton created seven paintings, making line drawings to define the various colour fields for each version. When he set out to make the print Release, he discovered that he had by chance kept the drawing defining the colour fields in the (e) painting and was able to use this as the basis for producing seventeen hand-cut stencils for building up the colours on the screenprint. For the final definition of the image in black, Hamilton created a photographic stencil from another accident: a photographic stencil created to use on the Swingeing London canvases had been cleaned of residual black ink between each use on a painting by pressing it on white paper, effectively creating a print. As the stencil had been used first on canvas, the texture of the fabric had been pressed into the black ink, with the result that the accidental proof had both the photographic image and the canvas texture. This was used for the final printing screen and its effects are visible in the transition between Proofs 18 and 19.
The artist’s inscriptions in pencil on each proof indicate the progression of colour, with details of the two missing proofs – stages 14 and 15 – inscribed on proof 13. These are: Stage Proof 1 – grey (P02416); Stage Proof 2 – warm grey (P02417); Stage Proof 3 – green (P02418); Stage Proof 4 – pink (P02419); Stage Proof 5 – grey (P02420); Stage Proof 6 – pink (P02421); Stage Proof 7 – flesh (P02422); Stage Proof 8 – Naples yellow (P02423); Stage Proof 9 – orange (P02424); Stage Proof 10 – blue (P02425); Stage Proof 11 – red (P02426); Stage Proof 12 – dark grey (P02427); Stage Proof 13 – warm grey (P02428); Stage Proof 14 – red (missing); Stage Proof 15 – transparent white (missing); Stage Proof 16 – darkest grey (P02429); Stage Proof 17 – applied die-cut silver (P02430); Stage Proof 18 – transparent black (P02431); Stage Proof 19 – second layer transparent black (P02432).
Like Release, the Stage Proofs were printed by the artist and Chris Prater at Kelpra Studio, London on Hodgkinson mould-made paper. It is not known whether they are unique.
Swingeing London III, 1972 (P04255) is another print generated from the screenprinting process of applying successive layers of colour using the same image.

Is this sleek mobile the only phone you need?
By TechRadar Staff 2008-07-02T12:15:49.183Z Mobile phones
Feature-packed smartphone with plenty to admire
Classy, minimalist look
Decent 3.2 megapixel camera
A-GPS sat nav
2GB microSDcard with maps and tunes
Awkward keypad
Rear cover feels cheap
The N78 may not be the priciest example in Nokia's N-series of 'multimedia computers', but this Symbian S60-powered smartphone manages to cram in a serious amount of functionality, including a 3.2 megapixel camera, quality music player and GPS sat-nav technology, all in a compact case that is a serious looker.
That case probably owes part of its minimalist look to the success of LG's Chocolate series with its hidden touch-sensitive buttons. But while the N78 features a plain black surround to its part-hidden keypad which lights up when pressed, it isn't touch sensitive.
You actually have to press the plastic case inwards at the sides to access some genuine buttons underneath. This does have a more reassuringly tactile response than many touch-sensitive varieties, though pressing the call end and cancel buttons on the far right of the handset (if you're right-handed) can be a bit uncomfortable.
It's thinner and lighter than its immediate predecessor, the N73, and the 16m colour screen is an improvement on the older phone's 262,000-colour display, while the numeric keypad is also radically different, comprised of four raised plastic strips running beneath the illuminated numbers.
This looks lovely and fits in very neatly with the phone's minimalist aesthetic, but it takes a bit of getting used to in practice, and isn't ideal for extended texting.
Simple navigation
The square D-pad conceals a secret that only becomes apparent in use.
It doubles as a touch-sensitive 'Navi-wheel', and running your thumb around the outside acts like the scroll wheel on an iPod, sending the cursor flying around the menus. It's a subtly brilliant piece of engineering that enhances your use of the phone without getting in the way.
Just to the right of the D-pad is a dedicated applications button (the traditional Symbian apps button is also on the keypad) which allows you to flick through the phone's features using a carousel interface that's very like the iPod Touch's one for viewing album covers. Very nice, in other words.
But while the front of the phone is very classy, the back reveals it as the entry-level model in the N-series range by feeling cheap and wobbly – it creaks when you press it, undermining the phone's high build standard elsewhere.
Speedy web browsing
Much of the N78's appeal is focused on the internet. It's 3G of course (plus quad-band GSM) and includes a 3.6Mbps HSDPA connection.
If you need to do some serious downloading there's also built-in Wi-Fi for full broadband access.
The browser is a joy to use on the large screen, allowing you to switch between landscape and portrait views. There's a zoom option and you can flick through previously viewed pages with ease.
Nokia's competent camera
The 3.2 megapixel camera with Carl Zeiss lens may be a few pixels short of the 5 megapixel model found on the higher-specced N95 and otherwise similar N82, but it produces some more than decent snaps.
It's quick to get into via a long press on the side-mounted shutter button and includes the N-series' standard raft of shooting and editing options, including timer, burst mode, brightness settings and an onscreen grid designed to help you to compose your pictures.
After you've taken your pic, you can add effects or text, as well as crop or rotate them as well as reduce red eye.
Powerful GPS
The built-in A-GPS transmitter can be used as a traditional sat-nav device, plotting routes using the well-integrated Nokia Maps feature (including a library of world maps with street and landmark details on a supplied 2GB microSD memory card).
Voice navigation is available for an additional upgrade fee, though Nokia promises to provide the first three months free of charge.
It also automatically adds location metadata to any pictures taken with the camera – very useful if you can't remember where you were when you took them, and for uploading direct to the web to share sites like Flickr, YouTube or Nokia's own Share On Ovi online sharing service.
Music player goodies
The N-series music player is one of the best currently available on mobile phones and is really only bettered by the iPhone and Sony Ericsson's Walkman range.
Even so, it's got a few extra tricks up its sleeve since as well as its FM radio receiver, it also has an FM transmitter so you can do an iTrip and send your music through your car radio.
There's also an internet radio function, offering access to hundreds of additional radio stations around the world. This soon racks up the data charges though, so it's best to use this with a Wi-Fi to broadband connection.
The supplied headphones are better than many out of the box numbers but there's a 3.5mm mini jack plug so you can add your own if you feel the need. The loudspeaker is also better than average with twin speakers placed on either side and at either end of the phone for an improved stereo image.
Incidentally, that memory card also comes with ten super-cool summer tracks including Matthew Corbett, Sarah Howells and the James Taylor Quartet.
Stacked with features
Elsewhere there's a PDF viewer and QuickOffice for viewing Microsoft Office docs (though you'll need to pay for the full Office suite if you want to create them yourself). As a Symbian phone there are also plenty more third party apps you can add.
Battery life isn't stunning but it's decent enough and we easily got three days of moderate use out of it, though heavy browsing reduced this dramatically.
With its above-average camera, high quality music player, sat-nav and maps combined with a fast, fun-to-use browser, the N78 packs a lot into a great looking and extremely pocketable package.
Looks: 7
Features: 9
Call quality: 10

Photos show alleged gold iPad mini 2 blinged out with fingerprint sensor
By Matt Swider 2013-10-22T00:44:00.294Z Tablets
iPad mini 2 with Retina display availability may be limited
Like Goldilocks, this rumor seems 'just right'
It's less than 24 hours before Apple's tablet-focused press conference, but that's just enough time for one final leak of an alleged gold iPad mini 2.
The eight photos from French site NowhereElse.fr are some of the highest quality pictures supposedly showing the 7.9-inch tablet.
In addition to being outfitted in the rumored gold color, the iPad mini 2 photos suggest that it will indeed feature Touch ID capabilities.
This assumption comes from the fact that the champagne-colored tablet depicted has a new "blank" home button that matches the one on the iPhone 5S.
iPad mini 2? Is that you?
It's actually hard to tell the difference between the alleged iPad mini 2 and the full-sized iPad 5 leaks, as the two tablets are expected to resemble each other.
Without another object in the photos to scale the 7.9- and 9.7-inch tablets, they're beginning to look exactly the same. They even both have the generic "iPad" insignia on the back.
That's great news for upcoming iPad 5 owners. The full-sized device is anticipated to have shed a lot of bezel and weight while keeping the big Retina display.
May be harder to find than the gold iPhone 5S (credit: NowhereElse.fre)
Retina availability unclear
iPad mini 2 is also expected to inherit the Retina display seen in other current Apple devices like the iPad 4 and iPhone 5S.
But prior reports suggested that the smaller tablet is going to be scarce due to the high resolution display.
Some have even suggested Apple may release a non-Retina model, though that rumor is far from confirmed.
What seems far more likely is that iPad mini 2 availability will be low until early 2014, much like the gold iPhone 5S to this day.
Read: Apple could debut a Surface-style keyboard with iPad 5.

Mycenaean findings: Gigantic 1250 BC building project in northern Copais
Acropolis of Agios Ioannis (photo: Greek Culture Minister)
The two-year research program "The Mycenaean Northeastern Kopais - MYNEKO" (2016-2017) was successfully completed and systematic excavation was carried out on the islets of Agios Ioannis and Pyrgos-Agia Marina in the northeastern part of the lake in northern Copaida, under the direction of Dr. Elena Kountouri, Head of the Department of Prehistoric and Classical Antiquities of the Ministry of Culture.
In these two places there were fortifications, residencies of houses with stone walls and superstructure of friezes, as well as burials under their floors, possibly children's, that enrich the existing data on the coexistence of living and dead in Middle Helladic settlements of mainland Greece. As the land at the two sites is extremely rocky for exploitation, it is not excluded that their inhabitants had achieved the creation of arable land at the edge of the lake, which, if confirmed, strengthens the view of some researchers on the Middle Helladic background of drainage works.

At the Acropolis of Agios Ioannis the cyclopean fortification, detectable in length of 560 meters, surrounds the plateau of the top, following the line of the rock eyebrow. Excavation cuts along the inner front of the wall revealed an elongated wall interfering with the inner wall of the fortification enclosure that presents, three meters across its internal face, rectangular projections known from buildings with warehouse operation or from internal enclosures on the Acropolis of Gla.
Of interest is also the revealing of an animal skeleton section carefully placed per se in a side of the semi-hard ground in a middle-Helladic layer, in the immediate vicinity of the wall. He was identified with a female equine, who also finds examples on horses that accompany burials in vaulted tombs of the Mycenaean times.

In the middle and northern hill of the hill, clusters of box-like tombs of the same period, which in some cases are surrounded by a stone built courtyard and covered by a low tumulus, according to the tradition of circular burial architecture with the Peloponnese and neighboring Fthiotida Antorns).
On the other hand, without a typological parallel, at present, it is a rectangular burial enclosure that has come to light, a particularity that may have implied the quality of the soil in combination with the family available burial space per family.
The building remains found on the hill of Agios Ioannis, combined with the mainly made of coarse and semiconductor ceramic cookware, allow the chronological redevelopment of the oldest, at present, residential building phase in this place around the middle of the 17th century BC . (Middle Helladic III / HR I period).

The results of the survey are particularly encouraging, as they brought to light new facts about the Middle Helladic and Early Mycenaean background of the settlements developed on the northern margin of the lake. In addition, the finding, with stratigraphic data, that the fortified settlements in the hills of Agios Ioannis and Aghia Marina have a phase of fortification, rehousing and abandonment chronologically analogous to the acropolis of Gla, ie around the middle of the 13th century BC, a milestone of the problems of the socio-political hierarchical relations of the Mycenaean northeastern coppaid field, as well as of the Orchomenos-Glas dipole.
Finally, it reinforces the opinion of the investigator that around 1250 BC a gigantic scale building project took place in northern Copais, at the initiative of the Orchomenos palace center.

Orchomenos, a continental and predominantly littoral force, which undoubtedly plays an early role in the region, was more focused on Central Greece, investing less in the overseas relations, such as Thebes, but in tending its unique natural resource in favor of the objective of self-sufficiency in cereals and other yields.
In order to achieve these goals, an extensive technical project for the drainage of the northern part of the lake was set up, the Gla Acropolis was set up in a crucial place to allow control of the drainage works of the lake, and a series of facilities were re- such as Agios Ioannis and Agia Marina, on the one hand for oversight of the sinks, the blockage of which could lead to a drainage project failure and, on the other hand, for the possibility of direct access to maritime trade routes.

The program was implemented with the financial support of the Institute of Aegean Prehistory (INSTAP), the Psycha Foundation and the company Lava SA, while the Municipality of Orchomenos and the Local Community of Akrafioni warmly supported the research.

A close collaborator of the program was Professor Michael F.Lane of Maryland Baltimore County University (UMBC), while Assistant Professor of Science and Technology at the Institute of Science and Technology in Archeology (EKETA) of the Cyprus Institute, Evi Margaritis, has undertaken the study of plant debris in order to reconstitute the paleoenvironment and the agricultural practices of the region.

Bundesbank gold location kept secret
debteurobundesbankunited statesfrankfurtbanksbunt
As pressure grows for Germany to tap its gold reserves amid the European sovereign debt crisis, the Bundesbank is refusing to end its silence on where its more than 3,000 tonnes of the precious metal is stored.
Economics Minister Philipp Rösler firmly ruled out digging into the country's reserves to help rescue the euro.
"German gold reserves must remain untouchable. I say this explicitly as Economics Minister, as representative of the Chancellor and as party chairman of the Free Democrats," he said on Monday on ARD television.
On Tuesday, the daily Financial Times Deutschland examined the speculation on where Germany’s horde of gold is being kept. The country's estimated 3,401 tonnes is the second largest national reserves after that of the United States.
Much of Germany’s gold would appear to be still in America, where it was held during the Cold War to ensure it never would fall prey to invading Soviet forces.
Although the Second World War had left Germany in ruins, the economic miracle of the 1950s which was largely based on exports, quickly built up enormous gold reserves. By 1968 Germany had 4,000 tonnes, the most it has ever held, the paper said.
Yet most of this was never moved to German soil – such a transport would be a logistical nightmare to organize, while insurance cover would be impossible to get. The gold changed hands on the trading floors of New York, London and Paris, while the metal bars themselves never moved.
West Germany’s financial centre Frankfurt, the home of the mighty Bundesbank, was in any case not considered safe enough – it was only an hour’s car drive from the Fulda Gap – the crucial weak spot in the German-German border where NATO planners feared an invasion by the Red Army could take place.
Former Bundesbank chairman Hans-Helmut Kotz told Stern magazine in 2004, “The largest share of our gold reserves are held in the Federal Reserve Bank, the Bank of England and the Banque de France. In that order.” His successors have never offered so much detail.
Even a written parliamentary question last November could not evince further information – only that the Bundesbank does have the gold in physical form, not in the form of delivery promises.
Rumours abound that the Federal Reserve lends the gold in order to earn interest, allowing banks to keep the gold price artificially low by short selling it on the market – something which the FTD said would profit many actors apart from gold owners and mine operators. Even though the central banks’ own gold reserves would be worth less in such a case, they would benefit from the stability indicated by a low gold price.
But as the FTD said on Tuesday, either the Bundesbank is lying or this theory of the gold price being depressed in this way does not fly – the paper was told by the Bundesbank that, “at the moment no gold is on loan.”
Critics suggested the storage of Germany’s gold in the United States was – and remains – a kind of political deposit, to ensure that West Germany remained tightly bound to the West.
This was disputed by the Bundesbank, whose spokeswoman said, “We are led by security, cost-efficiency and liquidity.”
Metals expert Thorsten Schulte told the paper that diplomatic considerations also probably played a role. “Taking the gold out of the US would be a sign of mistrust of the first order,” he said.
Karl Blessing, Bundesbank president in the 1960s is said to have written a letter to the American high commissioner in Germany promising not to convert the gold into dollars, the paper said.
Having large parts of German gold in New York, London and Paris would be useful in terms of saving on transport costs when it comes to selling. Around 60 central banks are said to have gold reserves in New York. “There are also serious sources which say the Bundesbank often brings small amounts to Germany,” said Schulte.
The reserves currently held in Mainz and Frankfurt are considered to be more than the four percent often cited – the Bundesbank told the FTD “a large share of the gold reserves” are in Germany.

Complementarity: Lessons from the Adams Family
August 24, 2015October 10, 2018By Susan Hanssen
As the history of the Adams family attests, the proper education of the young American requires both father and mother, grandfathers and grandmothers.
Alexis de Tocqueville called “the strength of American women” the great secret of the strength of the American republic. Likewise, strong women were the backbone of the Adams family and its contribution to the political integrity of the American republic.
The letters of John and Abigail Adams were first published by their grandson, Charles Francis Adams (President Abraham Lincoln’s ambassador to Britain). The diaries and letters of John Quincy Adams’s wife, Louisa, have just been published this year, a project explored by their grandson, Henry Adams. Henry Adams—who called Tocqueville’s Democracy in America the “bible of my own private religion”—worried that American men and women were losing their appreciation for the complementary strengths and gifts of men and women. He thought the best remedy was to hold up for Americans the image of his grandmother.
Part of the charm of John and Abigail Adams’s letters (which are frequently addressed with terms such as “Dear Miss Adorable” and “My Dearest Friend”) is the way that the two weave a life-long conversation about universal human virtue into their ongoing inquiry into their complementary contributions to mothering and fathering their “little flock” of children. Louisa Adams had a hard act to follow in such a renowned mother-in-law, but her journals reveal a woman of profound reflection—on the meaning of piety (filial, patriotic, and religious) and her role as daughter, wife, and mother.
The Only Perfectly Balanced Mind in the Adams Family
Louisa Adams is the only American First Lady to have been born in a foreign country. Her American parents were living in London when she was born, and during the Revolution she was educated in a French convent school. She married John Quincy Adams during his diplomatic work, and the two immediately set off for Prussia, where he was stationed. She had already endured a number of difficult miscarriages and given birth to her three sons—little George Washington, John II, and Charles Francis—before she made her first visit to her “native” land.
She was soon called on to leave her two oldest sons behind and accompany her husband to Russia with her youngest child. In Tsarist Russia, she endured a very personal “winter”: painfully separated from her older children, she lost her only infant daughter, received news of her own mother’s death, and had to travel alone from St. Petersburg to Paris in the midst of the Napoleonic wars.
Late in life, she bitterly reproached herself for having left her oldest sons behind while she accompanied her husband on his diplomatic mission to Russia. Both of those sons were deeply troubled youths, impregnating women before wedlock, and dying young from drink or suicide.
Only the son whom she had kept close to her carried on the family tradition of public service, political integrity, and a lifelong happy marriage with many children. In fact, his sons marveled at Charles Francis Adams as a man “singular for mental poise.” It seemed to them that it was the influence of his mother who had balanced the analytical tendencies of his father, which often led members of the Adams family to deep depression, bitterness, and drink. With a good dose of both mothering and fathering, he struck his sons as “the only perfectly balanced mind that ever existed in the name.”
Sexless as the Bees
When her grandson Henry Adams read Louisa’s diary, he was inspired to compare Russia to Woman, Woman to Russia—the two conservative forces at the beginning of the twentieth century. Russia acted as a conservative political force in Europe comparable to Woman as a conservative social force in America. Perhaps with the help of Russia the threat of an imperial Germany could be contained. Perhaps with the help of Woman the threat of a corroding materialism might be contained.
Each was powerful, but each powerfully directed its forces internally. Russia, he argued, had its axis of rotation around the Church and around agricultural production to feed its enormous population. It had not yet turned its forces toward industrialization and modernization. If Russia’s forces were ever to be ripped from its axis by, let’s say, an atheistic modernizing revolutionary regime, Adams wrote in 1905, it might destroy all of Europe.
But if Woman were to be torn from her axis of rotation around the cradle, it wouldn’t just destroy Europe—it could destroy human society. In his wide-ranging third-person autobiography, The Education of Henry Adams, Adams observed:
The woman’s force had counted as inertia of rotation, and her axis of rotation had been the cradle and the family. The idea that she was weak revolted all history; it was a palæontological falsehood that even an Eocene female monkey would have laughed at; but it was surely true that, if her force were to be diverted from its axis, it must find a new field, and the family must pay for it. So far as she succeeded, she must become sexless like the bees, and must leave the old energy of inertia to carry on the race.
In this context of a Tocquevillean fear of whether Russian absolutism or American freedom would triumph in the coming century and whether the American triumph would indeed be a victory for liberty or for the incessant pursuit of petty and paltry pleasures that “enervate the soul and noiselessly unbend its springs of action,” Adams held up, at the beginning of The Education, the image of his grandmother.
Education by Grandmothers
Henry Adams recalled his grandmother as the very portrait of religious peace. She was “a peaceful vision of silver gray” presiding over her old president, her china tea set, and her box walks. She was refined, gentle, fragile, delicate, and remote. As a boy, Adams “knew nothing of her interior life” but he sensed that she was “exotic”—that she did not belong wholly to the political world of Boston, with its confidence that a political utopia could be achieved on earth.
After “being beaten about a stormy world” and enduring a life of “severe stress and little pure satisfaction,” it was clear that she placed her hopes in eternity. The political world believed that absolute democracy, state education, and total freedom of speech would usher in the end times of history. The political creed was that “Human nature works for the good and three instruments are all she asks—Suffrage, Common Schools, and the Press.” All doubts of this creed were political heresy.
From his grandmother, Henry Adams gleaned his sense that there were values beyond the negotiable values of politics. Without her, his education would have been all Mars and no Venus—a purely political education with no religion—all war and no contemplation of beauty, all work and no genuine leisure. In the “Boston” chapter of the Education, Adams wrote:
The children reached manhood without knowing religion, and with the certainty that dogma, metaphysics, and abstract philosophy were not worth knowing. So one-sided an education could have been possible in no other country or time, but it became, almost of necessity, the more literary and political. As the children grew up, they exaggerated the literary and the political interests.
Without religion, the poetic imagination became utopian, and the political imagination became utilitarian. Americans worshipped “the Dynamo”—of the physical and mental energy of man—and were utterly lacking the cult of “the Virgin”—the contemplation of the laws of Nature and Nature’s God, and openness to the grace needed to fulfill them.
Louisa Adams always felt herself a fish out of water in a culture that gave more attention to the virtues of equality than to the virtues of piety and pity. She saw her role as wife and mother as that of an educator in the refined art of deference and condescension—the discernment and acknowledgment of realities of inequality, weakness, strength, power and infirmity, and a careful attunement to the unequal duties such differences gave rise to.
She considered a culture that saw nothing but equal duties, equal rights, and relations of convenience and mutual interest as a tyranny against her own nature. “My temper is so harassed and I am I fear so imbued with strange and singular opinions, and surrounded by persons with whom it is decidedly impossible for me to agree,” she exclaimed. “I feel that I have strange exaggerated ideas on most subjects which must be utterly incomprehensible but are utterly impossible for me to eradicate.”
One of her most ineradicable ideas was the sacredness of the bond between parents and children, the most palpable bond of piety and pity. She wrote:
It has been the fashion to say that as Children were not born to please themselves, no real ties bind them to their parents; and that blood relationship, should exact neither affection or gratitude—To my mind there is no truth whatever in such an assertion . . . From the moment of the birth, we incur a vast debt of gratitude which a life cannot repay
. . . There must be a great dereliction in that mind which could for a moment shrink from the acknowledgement of so vast a debt: founded in the weakest of all vanities, self idolatry!
Louisa Adams herself attributed the deepening of her sense of piety and pity to her experience of motherhood. She wrote that her religious opinions and sentiments had “‘grown with my growth, and strengthened with my strength’ though until I became a Mother; perhaps not properly weighed and considered; one more of precept, habit, and example than of meditated reflection.”
Adams worried that as Americans pursued a culture that was “sexless as the bees,” the complementarity that had produced the remarkable personal poise of his father—the balanced judgment, the eye for both contractual duties, and the more delicate bonds of affection—would be lost. To his mind, the proper education of the young American required both father and mother, grandfathers and grandmothers.

Titus Andronicus – An Obelisk
Titus Andronicus go back to basics on their new album An Obelisk
Album Review by Joe Creely | 19 Jun 2019
Album title: An Obelisk
Artist: Titus Andronicus
Label: Merge Records
Release date: 21 Jun
Titus Andronicus have always seemed to have at their core a near-demented ambition that set them apart from the myriad other bands walking a similar line between punk and heartland rock. They’ve taken in album-length extended metaphors based around the American Civil War and 90 minute, 29 track rock-operas before arriving here at what could ostensibly be seen as their ‘back to basics’ album.
An Obelisk, an examination of punk’s relationship with the self, swaps out the scrappy bombast of last year’s underrated but admittedly patchy A Productive Cough for a straightforward punk sound. It’s an odd move to separate out these two defining aspects of the band that always came together to make their best work, and the result is a uniformity to this album that their strongest work lacks. Ultimately, you're left with ten breakneck punk tunes with near identical guitar tones that become, after a certain point, near indistinguishable. The only tune that stands apart sonically is closer Tumult Around the World which is akin to Cheap Trick if Robin Zander smoked 40 a day and was having real trouble keeping it together.
That being said, Patrick Stickles’ haggard howl is incapable of sounding anything other than totally committed to whatever he is saying in the moment, and the record is at its best when it plays with this. (I Blame) Society and Beneath the Boot both walk a difficult line between sending up punk’s inherent contradictions and indulging in them, but pull it off with their energetic commitment.
An Obelisk is by no means a bad record. Each of its songs are solid if not spectacular, and Stickles’ lyrics are always interesting, but as an album it is let down by a lack of variety. You’re left thinking that there’s probably a single great album to be made out of their last two records.
Listen to: Just Like Ringing a Bell, (I Blame) Society, Beneath the Boot

Sheffield family win apology from airport after staff told Polly, 13, her diabetes medication '˜could crash the plane'
A Sheffield mum who said her family were made to feel '˜like terrorists' for carrying life-saving medication for their diabetic daughter has won an apology from Manchester Airport.
Tuesday, 18 September, 2018, 16:17
Joanne, Polly and Simon Holland have won an apology from Manchester Airport after being 'treated like terrorists' by security staff.
Joanne Holland, aged 47, complained after travelling to Naples in July with her husband Simon and their 13-year-old daughter Polly, who was diagnosed with Type 1 diabetes at the age of six.
Polly must have the essential medicine in her hand luggage at all times, and the family carry letters to this effect from Sheffield Children's Hospital whenever they travel abroad.
Despite this, the family were told to open all their medication and put it into individual plastic bags like other passengers' non-medical liquids, possibly damaging or contaminating it.
Later, they were called back through security by a member of staff who told Polly her insulin '˜could make the plane crash' and it would be '˜her fault'.
Joanne, of Millhouses, said: 'As a parent your children are always your priority but with Polly it is even more because I am carrying medicine that will keep her alive.
'For me it was frustrating but she was worried she would not be able to go on holiday. I just held her hand and said everything was going to be ok. She looked close to tears.'
Joanne - who says the family were left feeling anxious, upset and angry by the ordeal - has now received an apology from Manchester Airport which she says she appreciates.
However, she said the statement still leaves some important questions unanswered about their procedures when dealing with medicines and other liquids.
She added they will be '˜looking at alternative airports' in future to ensure her family's safety.
Fiona Wright, director of customer services and security for Manchester Airport, said: 'We'd like to apologise to the Hollands for their experience when travelling through the airport recently.
'The correct procedure for medicines and medical equipment is that they require scanning unless there is a written exemption from a doctor or hospital. This is why the Hollands were asked to present their daughter's diabetes medication for screening.
'Unfortunately, on this occasion some of the medication was not screened correctly so it was necessary to bring it back for additional screening. Â The safety and security of all our passengers is our number priority.
'However, we acknowledge the situation could have been handled better and this has now been raised with the staff member in question.'

Sturgeon mocks May’s conference cough before promising another Scottish referendum before 2021 regardless of Brexit
The Scottish First Minister delivered her annual address to the party faithful today, where she vowed to double spending on early years education and childcare
By Natasha Clark in Glasgow and Lynn Davidson
NICOLA Sturgeon mocked Theresa May’s conference cough yesterday.
Scotland’s First Minister brandished a packet of Strepsils during a flagship speech in Glasgow and declared: “I’ve come prepared.”

Sturgeon has vowed to never give up the case for an independent Scotland, and said she will “always” fight for the country to break away from the UK.
She told the party conference in Glasgow today: “we can, we must, and we will always make the case for independence.”
Despite trying to put the issue on the backburner at this year’s annual gathering with a promise to double spending on education and early childhood funding, she gave a huge pledge to the faithful members to hold another vote by the end of the SNP's term in Government in 2021.
Vowing that she still had a “mandate” from May's election to give Scotland a vote - despite losing a third of her Westminster MPs back in June - the Scottish First Minister insisted that the time WOULD come for another vote.
She was forced to put her plans for another vote on ice after the summer election - but has not given up on her dream of ripping Scotland apart from the rest of the UK.

She told the party conference she would never stop fighting for independence
Ms Sturgeon said today: “As I have always said, Scotland should have the right to choose our future when the terms of Brexit are clear.
“We have a mandate to give the people that choice.
“That mandate was won fairly and squarely.”
She resolved to “put Scotland in the driving seat” and not wait around to have decisions made for them.
Yesterday she said that she would continue to "make the fight" for another vote - and could call for one as early as next year.
And she said a second referendum on the terms of a Brexit deal would be "hard to resist".
But she admitted today that “people want clarity about Brexit first” before another vote.
"We may not yet know exactly when the choice will be made," she added.
"But we can, we must, and we will always make the case for independence."
She argued that as a result of the "chaos" of Brexit which would take the country into decline, "the need to do so has never been greater."
"There is a better future to be had for all of us, if we chose to build it, together," she vowed.
The First Minister also announced:
She will double spending on early childcare and education to £840million a year;
All care workers will be exempt from paying council tax;
Free sanitary products for all in schools, colleges and universities from next August;
The first Low Emissions Zone will open in Glasgow by 2020 to combat air pollution;
The Scottish Government will establish a publicly owned, not-for-profit energy company;
The public sector pay cap will be lifted in Scotland;
Scots will meet any Brexit registration costs for EU nationals working in public services.
What did Nicola Sturgeon say in her conference?
The First Minister said:
On independence:
"We are the party of independence.
"The case for independence doesn’t depend on Brexit.
"We may not yet know exactly when the choice will be made.
"But we can, we must, and we will always make the case for independence.
"With the UK government so engulfed in chaos and taking the country down a path of self imposed decline, the need to do so has never been greater."
On early education and childcare:
"By 2020, we will deliver around 30 hours a week for every three and four year old and eligible two year old.
"It will give children the best start in life. And working parents will save around £350 a month on the costs of childcare.
"Right now, we invest around £420 million a year in early years education and childcare.
"I can announce today that by the end of this Parliament, that will rise to £840 million a year."
On the Tories:
"There is a bankruptcy at the heart of this Tory Government.
"It is a moral one. The rape clause.
"The misery being caused to so many by the shambles that is Universal Credit.
"Treatment of disabled people so appalling that the UN brands it a human catastrophe.
"And all the while tax cuts handed to those who earn the most.
"That is Tory austerity. Heartless, shameful, self defeating.
"For the sake of decency, austerity must end - and it must end now."
On nuclear weapons:
"Our party stands proudly as part of the global movement for peace.
"So let us restate this today.
"No ifs, no buts from the SNP.
"We say no to weapons of mass destruction.
"We say no to nuclear weapons on the River Clyde, or anywhere else."
On Brexit:
"15 months on from the Brexit vote, the Tories’ failure to guarantee the rights of EU citizens to stay here shames them.
"We don’t have the power to guarantee these rights ourselves. I wish that we did.
"But we will act where we can.
"But if a fee is imposed, I can confirm today that - as a minimum - the Scottish Government will meet the cost for EU nationals working in our public services.
"It will send a clear message to our fellow EU citizens, in actions not just words, that we welcome you, we value you and we want you to stay.
"We want Scotland to stay at the heart of Europe."
But to pay for her new policies, she hinted that there would be tax hikes ahead.
She said today that “it is right to consider how our limited tax powers might help us protect what we value most”.
“We want to be a fair, independent country,” she stressed.
She also used her speech to hit out at the “heartless, shameful, self defeating” nature of Tory austerity.
And lashing out at Scots Tory boss, Ruth Davidson, she urged her to condemn the “racism, misogyny and sectarianism within their ranks”.
“It’s time Ruth Davidson found some backbone and kicked the racists and bigots out of her party,” she stormed.
Humza Yousaf told conference today that the "time will come" for another vote and that the party will pursuade them that "our future is best decided in our own hands".
The Scottish Transport Minister said: "I promise you we will win independence for our country and by God don't we need it now more than ever."
However, Ms Sturgeon's annual address to the party comes just a few days after a YouGov poll for The Times shows that 50 per cent of Scots would still vote No to independence if another vote was held today.
And other analysis showed that the next Scottish Parliament would likely lean in favour of unionists, as opposed to Scottish Nationalists.
The Tories said the electorate were not likely to give her another 10 years in power.
Scottish Tory deputy leader Jackson Carlaw said: “What Nicola Sturgeon seems to forget is she’s already had more than 10 years in power to do all the things she speaks of here.
“The SNP are on a slippery slope, and it’s unlikely the electorate will grant her another decade.”

"You know Boulder does it better than anyone," an unidentified female says at the beginning of the video. "We'll show you Boulder."
The YouTube sensation comes on the heels of Boulder launching a new ad campaign aimed at highlighting the school's academic achievements, after Playboy ranked the school as the number three party college in the nation.
Individuals were seen drinking large volumes of alcohol in the viral video. (Image source: Screen grab via YouTube)
According to the video's producers, it was aimed at generating publicity for a new smartphone application called "Blend."
The application "lets students share unique experiences and get free stuff from their favorite brands," according to it's description on the Apple iTunes store website.
CEO and founder of Blend Akash Nigam defended the video's representation of Boulder culture in an interview with KDVR.
"Universities do party like that," he said. "You could be at Princeton and they do that."
Nigam added he intended the video to stir controversy.
"We felt like something like a video like that would definitely be viral enough to get our name out and it did," he said.
But some students on campus had no idea what the video was advertising. One thought it was aimed at showing off the school, another suggested the app's creators get back to the marketing table.
University officials say this video doesn't accurately portray the University of Colorado — Boulder. (Image source: Screen grab via YouTube)
"They should try a different approach," an unidentified female student said. "That's not the only way to reach out to college kids."

Katharine Murphy on politics
There's a whiff of some significant political calls in the air
Katharine Murphy
Coalition SUV lovers are grumbling about car emission standards, and Labor wonders if it has the bottle for a tax fight

Next week, MPs will return to Canberra for the final parliamentary sitting fortnight before the winter break, ending several weeks of suspended animation.
A number of government policies are creeping towards a resolution of one kind or another. The national energy guarantee will either sink or swim over the next couple of months, and I suspect some government MPs will also use the opportunity of parliament’s resumption to start making noise about the next phase of the emissions reduction fight – new vehicle standards.
In 2017, the government released a series of proposed targets for vehicles in discussion papers seeking input from industry. Under the strongest target considered, new cars would have to cut their CO2 emissions by 45% below current levels by 2025 – from 192g of CO2 a kilometre to 105g.
While the key decisions are yet to be made, the internal grumbling is already under way. Nationals and some Liberals are huffing and puffing about the sanctity of man and his SUV.

Honestly, all this would really drive a saint mad. The same group of naysayers (members of a government that voluntarily signed the Paris climate agreement, just for the record) have already prevented Josh Frydenberg from settling on an emissions reduction target for electricity that would have delivered abatement at lower cost than having to chase significant (expensive) emissions reduction in transport – and now they also want to object to the government trying to land a strategy for vehicles.
But as irritating as these utterly predictable shenanigans are, the real definitional fight of the political fortnight will be on tax. A short recap might be in order, given political tragics have doubtless been distracted by Donald Trump’s efforts to completely upend the global order over the past couple of weeks.
The Turnbull government used the May budget to set up the please like me conversation it wants to have with voters on personal income tax cuts. The rest of the parliamentary players have been mulling their options ever since.
Labor supports phase one of the tax cuts. The government’s proposed low and middle-income tax offset will give $530 to 4.4 million taxpayers with incomes between $48,000 and $90,000 in 2018-19.
Labor is yet to determine a position on stage two, which lifts the top threshold for the 19% rate from $37,000 to $41,000 and lifts the top threshold for the 32.5% tax rate from $90,000 to $120,000. Labor is hostile to stage three, which abolishes the 37-cent tax bracket from mid-2024, in the process delivering a mighty handout to high income earners.
Labor wants to split the bill to allow passage of stage one and possibly stage two, while sinking stage three. But the government says it won’t split the bill, not on your nelly.
Now we enter Canberra’s favourite game of Senate bingo. Turn your eyes now to the Greens, because without the Greens, Labor has zero chance of splitting the package (or more precisely, moving amendments to strip out various schedules).
What will the Greens do? Well, we don’t know yet, because the party is yet to make a decision. That will happen next week.
Tax cuts are awful for 'middle Australia'. Pretending otherwise is misleading | Greg Jericho
You might not have noticed, because everyone has to emote like shrieking banshees to be noticed these days on our cluttered political stage, but the Greens are opposing all tax cuts. Nope, nope, nope has been the party’s post-budget stance. If they persist with that disposition, then splitting the package becomes entirely hypothetical, because the numbers won’t be there.
If the Greens to decide to set aside nope in an effort to work with others to try and torpedo the tax cuts for high-income earners, then there is a prospect of getting the numbers to strip out schedules.
The South Australian independent Tim Storer will only support phase one of the package, which makes him an implicit yes for splitting the bill. Stirling Griff of the Centre Alliance says his Senate bloc of two is also open to splitting the bill.
The Centre Alliance supports phase one and two of the income tax cuts, and might yet support phase three, but won’t make a decision on that until next week. Centre Alliance has commissioned its own analysis on the impact of stage three, and wants to digest that before making a decision.
Even if they do sign up, Griff thinks stage three is entirely hypothetical in any case given it will be delivered two election cycles away. He told me this week: “We don’t have a problem with splitting the bill”. That takes the splitters faction very close to having the numbers.
In the event efforts to split the tax bill fail, either because the numbers don’t materialise or because the government point blank refuses to accept the Senate’s handiwork, then Labor will have to make a choice.
Does it then wave the lot through (despite its objections) in order to give low and middle-income earners certainty around getting their cash rebates next July? Does it say yes on the proviso that it will scrap the tax cuts for higher-income earners if it wins the next election?
The alternative is sinking the package. It’s a big thing to stand between a voter and a tax cut. It would be a hard thing to do politically, both for Labor and for the various crossbenchers. It would take some bottle.
It’s hard, but not impossible. In the event that’s where things end up at the conclusion of our game of chicken – Labor can point to the government’s unreasonableness. It can say (correctly) that the numbers are there now to pass stage one (and perhaps two) of the plan, and the reason that hasn’t happened is Scott Morrison has refused to split the package, because the treasurer is being a man-baby.
So stepping through all that is a long way of me saying the major parties (and the Greens and various crossbenchers for that matter) are on the brink of some significant political calls over the coming fortnight.
The government will have to decide if it really wants to play all or nothing with the income tax package, and Labor (and others) face the same decision.
Also in the back of people’s minds around the parliamentary precinct as the winter begins to grip is the timing of the next federal election.
Many in Labor are convinced the government will pick the fight on tax rather than look for a settlement and then dash for the polls some time over the next few months – particularly if the Liberals end up performing well in the byelections in Longman and Braddon at the end of July. The hint of momentum would be hard for a battered government to resist.
The logic of that is hard to argue with, except the prime minister keeps insisting he won’t do that – that he will run full term. He says that every time he is asked.
Now, is the prime minister a man of his word? Thus far Malcolm Turnbull has made much of not breaking any promises (unlike another prime minister who may have occupied the post immediately before him), but as is sometimes observed in the classics, only time will tell.

Court battle, trade war and 5G spell tough 2019 for Apple in China
null | 5 Jan 2019 2:03 PM GMT
Apple Incs chief executive Tim Cook has his work cut out in China this year the iPhone maker faces the looming threat of a courtordered sales ban, the uncertain outcome of trade war talks and the rollout of a new 5G network, where it finds itself behind rivals like Huawei and Samsung
Apple Inc’s chief executive Tim Cook has his work cut out in China this year: the iPhone maker faces the looming threat of a court-ordered sales ban, the uncertain outcome of trade war talks and the roll-out of a new 5G network, where it finds itself behind rivals like Huawei and Samsung.
The complex outlook raises a challenge for Apple as it looks to revive its China fortunes after weakness there sparked a rare drop in its global sales forecast, knocked $75 billion from its market valuation and roiled global markets.
Cook told investors that the main drag on the firm’s performance in China had been a sharper-than-expected slowdown in the country’s economy, exacerbated by the impact of trade tensions between Washington and Beijing.
“We did not foresee the magnitude of the economic deceleration, particularly in Greater China,” he said.
Chinese shoppers told Reuters another element had been key: the high price-tag on Apple’s flagship phones.
Analysts said the firm faced a brewing storm of challenges: an economic slowdown, stronger rivals like Huawei Technologies Co Ltd bringing out comparable tech at lower prices and bubbling patriotic sentiment amid the trade war.
A Chinese court has also issued a preliminary injunction banning some Apple phones, part of a legal battle with chip maker Qualcomm Inc. This ban, potentially hitting iPhone models from the 6S through the X, has yet to be enforced.
On Thursday a local industry body, the China Anti-Infringement and Anti-Counterfeit Innovation Strategic Alliance, called on Apple to heed the court order and not “trample the Chinese law by leveraging its super economic power and clout.”
Apple declined to comment on the group’s statement but has previously said it believes its current phones comply with the Chinese court’s order.
“These are tough times for Apple in China,” said Neil Shah, research director at Counterpoint, adding the iPhone could see its market share slip to 7 percent this year in the face of stronger local rivals and worry about the sales ban.
Apple’s market share in the third-quarter of 2018 was around 9 percent, and has dipped from above 14 percent in 2015, overtaken by local rivals like Huawei, Oppo and Vivo.
5G STRATEGY
Another question mark for Apple is its 5G strategy in China, where the US firm is not expected to have a 5G-enabled phone until 2020, behind rivals like Huawei, Xiaomi Corp and Samsung Electronics.
China is looking to push ahead with its rollout of a faster 5G network, with a pre-commercial phase this year and a commercial network in 2020.
Some are looking to make an early bet on the technology. Huawei is planning a 5G phone mid-year, while Xiaomi is aiming for the third quarter. Samsung is expected to unveil a 5G phone in the first half of the year.
Industry insiders, however, said Apple would likely hold off until the fall of 2020 to have its own 5G-enabled phone, a strategy that would bypass the untested early period of the technology, but which could mean Chinese shoppers delay iPhone purchases or buy another brand that switched to 5G earlier.
“I’ll definitely be paying attention to 5G functionality when I buy my next phone,” said Wu Chengjun, a graduate student in Beijing who currently uses an iPhone X.
With the exception of Huawei, which makes it own 5G chips, Qualcomm is providing the technology to many of the major phone makers releasing 5G handsets this year.
“If you’re a [phone maker] looking for a ‘super cycle’ [of sales], if you don’t have 5G, your situation won’t get any better,” Cristiano Amon, Qualcomm’s president, told Reuters in an interview. “The carrier channel is going to be incentivized to start selling 5G phones in the second half” of 2019, he said.
But there are risks integrating 5G too early into high-end smart phones because the technology requires deeply re-designing the devices with multiple new antennas. Given spotty coverage in 2019, gambling on a new design before networks are mature could be more risk than reward, said Darryn Lowe, a Bain & Co partner who works with the wireless industry.
“When you think about 5G, it’s a heck of a lot more complicated than an aluminum strip running around the phone,” he said.
And other shoppers and analysts said Apple’s more cautious approach to 5G made sense and that the firm would not likely lose out too much to rivals by delaying its launch.
Apple’s decision to wait to adopt 4G until after other makers didn’t hurt it. But that was when consumers commonly purchased a phone every two years, a cycle that has elongated and might prompt buyers to want a more “future proof” device, said Glenn Lurie, CEO of Synchronoss Technologies and the former head of AT&T’s wireless unit.
“If you’re going to walk in to make a 30-month decision, the concept that I’ve already got 5G built in, it feels pretty good,” Lurie said.
But buyers such as Li Hongzhuo, 22, a student in Beijing, said he was interested in 5G, but it wouldn’t be the deciding factor and he preferred to wait until the technology was tried and tested.
“Typically my needs for my phone are high speeds for downloading videos or transferring files from chat apps. This will get faster (with 5G), but 4G already satisfies my needs,” said Li.
“I won’t really consider switching my phone until 5G has been operating stably on the market for some time without any bugs – or unless they stop offering 4G.”

Room together: In the new Malayalam cinema, the macho men no longer corner all the space. A file image of actor Mohanlal in the film Pulimurugan
The greater visibility of the gentler, nearly non-violent masculinity in Kerala is a welcome sign. But how many of us are ready to shed the conventional gender binaries?
Two gruesome incidents have shaken Kerala in the recent past: one, the molestation of a young female actor by four men who trapped her in a moving car and filmed their despicable acts; the other, the custodial torture of a young dalit in a police station, which drove him to kill himself.
In both, public outrage was palpable and the government as well as political parties had to swiftly condemn the violence and act against the perpetrators. Yet the difference between them is also stark. In the first, the victim mustered up the courage to make public the torture she had suffered through a police complaint and to resist public shaming. The second story is tragic; the young man couldn’t bear the insults heaped on him. Interestingly enough, the police force that keenly investigated the first incident to bring the perpetrators to book, are the accused in the second. Clearly, the huge gap between class and caste positions of the victims as well as cultural capital explains much, especially the attitude of the police.
However, what saddens me most is that we do not sufficiently recognise that the violence was sexualised not just in the first incident but also in the second.
There is reason to think that the second incident, the torture and death of 19-year-old Vinayakan, who worked at a beauty salon, is not just an atrocity against dalits. The nature of the violence inflicted on this innocent teenager was clearly gendered violence. The torturers had chosen to humiliate him by targeting those parts of his body which did not conform to conservative expectations of a ‘properly’ gendered male body. His hairstyle and earrings provoked them; they injured his nipples repeatedly causing grievous hurt to both body and dignity. In other words, this was, partially, rape. It also reeks of the intense transphobia that many among the police continue to nurse. For Vinayakan’s preferred body-styling complicated gender binaries in sartorial codes, quite common in Kerala. Protests organised in Thrissur emphasised the freedom to dress, and men who challenge such codes were prominent in them, particularly the singer Martin Oorali. To my mind however, the important contrast between the two cases lies in an apparent inversion: in a society where raped women are pushed towards suicide, here, a young woman managed to rise above all such viciousness, while a young man found life unbearable. What does this tell us?
Firstly, it tells us that post-Jyoti Singh Pandey, the widespread discussion of women’s safety has translated into a degree of public consensus in favour of women, especially when the complainant is socially and economically privileged. This seems evident in the recent incident at Chandigarh too. Attempts to shame and bully the Kochi survivor were condemned roundly and she was offered support from many quarters, especially by her peers. Such was the pressure that authorities had to respond effectively. A tea ad had her talking coolly about “life’s hurdles”, which, she claimed, “make us discover our inner strengths”. Inverting an irresponsible remark made EK Nayanar, former chief minister of Kerala, that rape in the US was so frequent that it was like drinking “a cup of tea”, here, “life’s challenges” are to be surmounted with just a cuppa!
Secondly, in sharp and tragic contrast, young Vinayakan chose to take his life. He did not even have the language to express the torment and humiliation he suffered. His body had suffered something akin to rape, and in a country that does not recognise even male rape, how could he demand justice? By humiliating him thus, the policemen punished him for having crafted a male body which did not conform to, or pay its respects to, the ideal of manly physique. His dalit status made it worse — it was not the first time that police in Kerala unleashed violence against dalit men dressed differently.
Of late, we have seen the rise of gentler, nearly non-violent masculinity in different sites in Kerala. We find less polarised styles of dressing in the State, particularly by young men. They hang about in mixed groups, and are not shy to flaunt the gender trouble they stir up. In the new Malayalam cinema, the macho men no longer corner all the space.
It may, then, be the time for us to take seriously the shifts in gender divides on the ground, intensified, no doubt, by the considerable visibility of the transpeople. ‘Men’ are no longer a given; it may be time to acknowledge the vulnerability of all bodies excluded from the world of macho men.

Beckham tells Man Utd star Rooney: Continue until…
by Andrew Slevison 2016-09-05 14:04:42.000000
David Beckham has urged Wayne Rooney to play for England for as long as he can.
The Three Lions skipper broke Beckham's record for most appearances by an outfield player when he amassed his 116th international cap in Sunday's World Cup qualifier against Slovakia.
Some pundits have called for Rooney, 30, to soon pull the pin on his England career in order to focus on Manchester United but former club and country colleague Beckham does not agree.
In a message on Instagram, Beckham wrote: "So tonight Wayne becomes England's most capped outfield player...
"I keep hearing some people say Wayne should stop playing for his country to prolong his club career... Seriously?...
"As a player you retire when you're ready. Representing your country is the highest level anyone can reach, walking out in an England shirt at Wembley is one of the greatest feelings you can ever have...
"Every kid around the world that loves this game dreams of playing in their national team colours and representing the country they love...
"Don't let anyone take that away from you, continue until you can't give anymore... Congratulations mate"

Tri the Parks Triathlon Race Series Race Transfer Policy
Due to the number of race transfer requests and cancellations that occur in the weeks prior to a race we have implemented the following policy that is in accordance with USAT Policy. This policy has been created in fairness to all the athletes so that equal opportunity exists for registering for a Tri the Parks Triathlon Race Series event. There are no race day registrations or race transfers on race day for any Tri the Parks Triathlon Race Series event, even if a registered athlete is a "no show" and a slot is available. This policy has been implemented in fairness to all other athletes who registered for the event to ensure that events start on time, for safety considerations and event management.
Refunds will not be issued after a registration has taken place, but under certain circumstances, race transfers can occur. A race transfer is defined as transferring an athlete's registration to another race for any reason (injury, unexpected calendar conflict, etc.) A race transfer can occur under the following conditions. The request to transfer out of a race must be made 14 days or more prior to that scheduled event date. No transfers will be allowed underneath this deadline. The fee for a race transfer is $15 and must be received before the 14 day window for transfer expires. Transfers can be made to any race in the Tri the Parks Triathlon Race Series under these conditions. However, there are no transfers from the last race of the season to another race in the following season. A transfer can be requested for a race scheduled earlier in the season as long as it is made while the "transfer to" race is still open for registration.
Considerable effort goes into producing an event such as a triathlon and funds are expended and applied in good faith based on a registration. Transferring two weeks out from an event can be managed, but under the two week limit a transfer causes considerable issues both monetarily and organizationally as packets have been prepared with sized t-shirts, chip numbers have been requested based on the athlete's entry, and perhaps a race has been closed in which a transfer would bar another athlete from entering the event.
Thank you very much for your understanding of this policy and thank you also for your participation in the Tri the Parks Race Series.

Q&A: Kenco's Richard Scott on Amazon's Fleet and Trucking Technologies
October 31, 2017 • by Jack Roberts

Amazon’s addition of a fleet services division to its already-vast logistics empire will be highly disruptive to many aspects of the trucking industry. In this exclusive HDT interview, Richard Scott, vice president of transportation for logistic solutions provider Kenco, weighs in on what Amazon’s new venture will mean for the future of last-mile delivery operations and e-commerce at large.
HDT: What does the entry of Amazon into the fleet delivery service space mean for the current state of last-mile delivery techniques and the growth commerce?
Scott: For speed, it’s a great concept. High-speed delivery services are inherently expensive. Putting high-speed and low-cost together can have some problems, namely the quality of the delivering agent for the end customer. The consumer may not know who or what agency is going to pull up to their front door with their package. The vehicles are inconsistent and the drivers can be inconsistent, which can put off some consumers. The larger delivery agencies (FedEx, UPS and USPS) have consistency in their hiring and delivery practices, and known names and brands that rely on their reputations for quality service. It will have an effect on volumes through traditional services, but how much will need to be seen.
HDT: General transportation pain-points are apparent, and become especially visible as we lead into the holiday season. Will Amazon bring changes that improve efficiencies year ‘round and during peak holiday periods?
Scott: This holiday season is going to prove to be interesting. Driver capacity is at an all-time low and getting worse, with little relief in sight. Baby boomers (the largest driving generation) are retiring with few new drivers entering the field. Regulation and hiring restrictions are further pressuring the market. Add that to the amount of equipment sidelined due to the Texas and Florida hurricanes, and we have a mess. Rates are going to go up which will have a direct effect on shippers and consumers. Carriers should be looking hard at retention of their existing workforce. An interesting side effect of the looming holiday season is that the parcel carriers are pushing their larger retail customers to run promotions much earlier in November to encourage a longer buying season versus a major spike last minute.

HDT: What other steps are trucking companies and logistics providers taking to get ahead of the holiday rush?
Scott: For our operations, the holiday season has already begun. A decade ago, there was a major push in late November through Christmas. Shippers and distributors have gotten smarter and are getting inventory to where it’s needed much earlier. The holiday season will have the greatest effect on the parcel/LTL markets. To combat the holiday rush, UPS has announced that they plan to hire 95,000 temporary workers, and FedEx will hire 50,000 as well. Many shippers have indicated that they are targeting college students, retirees, and boosting overtime bonuses.
HDT: How do you see the future of trucking shaping up with baby boomers retiring and a lack of younger drivers entering the industry?
Scott: The baby boomers are the largest segment of truck drivers. Many of them were about to retire before the Great Recession, so they had to continue to work in order to rebuild their retirement savings. They have now recovered and are starting to retire. There’s also some rumors of many of independent contractors, especially the baby boomers, leaving the market due to the ELD mandate. The larger carriers are conducting research studies to determine how to recruit and motivate the new millennial workforce – they are finding that unlike common misconception, they are willing to work hard, but they must be tech-enabled, connected and motivated by comfortable and “cool” equipment. This shift may just drive a new level of investment in equipment from traditional carriers in the near future.
HDT: What role do you see in terms of advanced and new technology transforming the industry going forward (e.g. drones, electric vehicles, autonomous vehicles, connected vehicles and V2I)?
Scott: Autonomous vehicles and platooning are the only short- to mid-term solution to the driver shortage because of the issues you mentioned. A lot of effort is being put in by OEMs and regulatory agencies to pave the way for these technologies to advance. The main obstacle, in my opinion, is the public perception of a driverless vehicle. It will be necessary for the industry to take a phased approach to this concept – platooning, where the leading vehicle is manned and the others are unmanned but connected, open road experiments with drivers present in case of emergency, eventually moving to unmanned interstate non-urban driving etc. This approach can ease the social concerns and prove the technology over time.

Groom & Pageboys
Venues Pendennis Castle
Falmouth, Cornwall
Impressive 450 year old castle keep
Historic barracks transformed into modern venue
Situated in Falmouth, Cornwall
Civil ceremonies for up to 120 guests
Drinks receptions in the Castle Chemise 120 guests
Evening receptions for up to 120 guests
Marquee receptions for up to 1,500 guests
The beautifully historic Pendennis Castle can be found in the seaside town of Falmouth. You can marry in the Castle Keep itself; you'll feel like royalty as you cross the stone bridge and begin walking down the aisle through a stunning arched doorway. You can then spend your first moments of marriage outside on the grass-covered Chemise that surrounds the Keep.
Get married in the truly unrivalled location of Pendennis Castle…
The newly refurbished Royal Artillery Barracks are available for receptions of up to 120 guests. The Barracks have been brilliantly converted into a contemporary banqueting suite and offer amazing sea views. Alternatively, if you're hoping for a more elaborate celebration, the castle's lawns offer plenty of space for a marquee that's large enough to hold 1,500 guests.
This picturesque castle was originally used as an artillery fort after its construction in 1539-1545. Commissioned by Henry VIII, the castle played an important role in the defence of England against invasion. Pendennis continued to be used in coastal defence until World War Two, most notably when housing Territorial Army volunteers during World War One.
The Lower Gun Room
Located within the Castle Keep, the Gun Room is one of the most historic places in which you can marry. Built nearly five hundred years ago, you will enter the room by crossing a stone bridge and passing through a beautiful arched doorway. The Gun Room is a particularly beautiful space for wedding ceremonies, with rustic wooden benches for your guests to sit on, gunpowder barrels and tapestry hangings.
Civil ceremony capacity - up to 120 guests
Drinks reception capacity - up to 120 guests
Castle Chemise
On sunny days, you and your guests can venture out onto the Chemise; a grass-covered area surrounding the castle and bordered by a circular stone wall. For many years this area was used as an external gun platform! Now, it offers a perfect space for wedding photography.
Near to the historic Castle Keep stands the Royal Artillery Barracks which were built in 1901. Once used to house the Royal Garrison Artillery, the Barracks now offer couples the chance to hold their ceremony or reception within one of its three rooms.
In contrast to the historic surroundings, the Barracks feature clean and contemporary décor, as well as stunning sea views.
Civil ceremony capacity - up to 90 guests
Evening reception capacity - up to 120 guests
For really big receptions, the lawns surrounding the castle make a perfect spot for a marquee. You and your guests can celebrate your marriage while enjoying views of this stunning castle and adjacent coastline.
Marquee hire must be sourced from English Heritage approved suppliers.
Evening reception capacity - up to 1,500 guests
The team at English Heritage have created a list of accredited catering suppliers for you to choose from. They also provide a range of specially selected Wedding Packages to include venue hire, catering, candle arrangements and a DJ.
There are two specially converted holiday Cottages available to rent within the Castle Grounds.
You will also find many hotels in the nearby Falmouth town centre.

Yes, Windows 10 is Coming to Low-End Windows Phones
Posted on February 9, 2015 by Paul Thurrott in Windows 10 with 0 Comments
Microsoft has been backpedaling somewhat on its promise to deliver Windows 10 on “all” Lumia handsets, a statement that could easily have been (mis)interpreted at the time as “all Windows Phone 8.1 handsets.” But after affirming that it plans to provide the update even on low-end Lumias, a Microsoft executive this past week started resetting expectations yet again.
The issue here is obvious enough. While Windows 10 will run hardware as diverse as embedded Internet of Things (IoT) devices, smart phones and phablets, tablets of all sizes, laptops and detachable PCs, desktop PCs, and even Xbox One, it won’t offer the exact same features everywhere. And when you look at the Windows Phone market, or the Lumia market more specifically, only the lowest-end and least capable devices have sold well. Indeed, the Lumia 520 was the best-selling Windows device for calendar year 2013. And that handset was as low-end as they come when it was released, let alone today.
But promises are promises. Microsoft hasn’t yet divulged any details, but the company did admit to me during a campus visit last month that it would indeed be able to deliver Windows 10 to Lumias and other Windows Phone handsets despite its ongoing issues getting lesser updates out to phones. (Reference: Verizon Wireless v. Lumia Icon owners.) It will explain those plans at or before Build in late April, I was told.
Which leaves us with the obvious question: If Microsoft cannot or will not deliver a Windows 10 update to Windows RT users, what the heck will this update look like on low-end Lumias like the Lumia 520, 530, 625 or 630, each of which has just 512 MB of RAM?
It will look like … less.
In a series of tweets over the weekend, Microsoft’s Joe Belfiore tried to reset our expectations about what this update would look like, but also reaffirm that low-end users—i.e. 90 percent of all Windows Phone users—won’t be left out in the cold.
“We are working on Windows 10 for 512 MB devices, including the Lumia 520,” he tweeted (sort of: I’ve expanded this character-limited blurts into actual English for your convenience). “Our ambition is to make Windows 10 available for these devices but features may vary.”
“Timing for various phones may be variable as well,” he added. “When we first launch the Windows Insider program [for phones and small tablets], it’ll be [available for] a subset of phones with more [phones being added] later.”
“Also, we’re on track for Insider build coming “in February” as Terry [Myerson] said at our January 21 media event,” he wrote. “We need to complete internal testing first, [so] hang in!”
So this may seem like bad news, but compared to what’s happening with Windows RT—those poor guys aren’t even getting Windows 10—this is a much more reasonable situation, especially when you consider how much is missing from these low-end handsets. But then it makes sense for Microsoft to focus on the devices that sold (relatively) well. Windows RT just didn’t find an audience, and while Windows Phone is struggling compared to Android or iOS, Microsoft and its partners sell tens of millions of these devices each year.

Huge incendiary kite from Gaza lands on kibbutz power lines
IDF strikes cell in northern Strip launching devices as arson attacks continue; flaming balloon lands next to a community dining room in Eshkol Region
By TOI staff 11 August 2018, 4:51 pm 12 Edit

A large incendiary kite launched from Gaza landed on power lines near Kibbutz Sufa, sparking a quick operation by employees from the Israeli Electric Corporation to remove the device before a fire was started.
The 4-meter (about 13-foot) kite, which landed on Friday, caused a power outage at the kibbutz and in the surrounding area.
It was removed from the high-voltage wires by electric company workers using a crane.
The IEC released pictures of the kite on Saturday.
In another community near the Gaza Strip, police sappers neutralized an incendiary balloon flown over from the Hamas-run Palestinian enclave that landed next to a dining room in an Israeli community in the Eshkol Region.
In response, the Israeli military on Saturday afternoon said it targeted a cell responsible for launching incendiary balloons in the northern Gaza Strip. Reports in Palestinian media said two people were injured in the Israeli strikes in El-Bureij.
There were also Palestinian reports of a second IDF strike elsewhere in the Gaza Strip.

Earlier, another incendiary device sparked a fire in the Nir Am nature reserve. The blaze was largely under control by Saturday afternoon, according to the Parks Authority.
Southern Israel has experienced hundreds of fires as a result of incendiary kites and balloons flown over the border from Gaza in recent months. Over 7,000 acres of land have been burned, causing millions of shekels in damages, according to Israeli officials.
The arson attacks Saturday came on the heels of clashes along the Gaza border on Friday that saw three Palestinians killed, according to the Hamas-run health ministry in Gaza. Several thousand Gazans gathered in different locations along the border, setting tires ablaze and throwing rocks and Molotov cocktails at Israeli security forces.
Several attempts were made to breach the security fence.
Israeli tanks struck two Hamas posts in the Gaza Strip Friday evening after a grenade was hurled at troops and amid intense violence during the mass riots. Authorities said nine fires broke out in southern Israel on Friday that were sparked by Gaza incendiary devices.
The violence that erupted over the weekend came after Hamas and Israel appeared to be honoring an informal cease-fire that ended two days of intense violence amid efforts by neighboring Egypt to negotiate between the two sides.
Hamas’s Al Aqsa TV channel reported late Thursday that the Egyptian-brokered deal took hold “on the basis of mutual calm.” It was at least the third such truce in recent weeks.
But Hadashot TV news reported on Friday that Israel denied making any ceasefire agreement with Hamas to end intense the Gaza rocket fire into Israel, which had prompted IDF response attacks Wednesday and Thursday.
A senior Israeli diplomatic official insisted to Hadashot that Hamas’s announcement that Jerusalem had agreed to a truce was a lie. A senior defense official backed up the claim, and added that the army did not see the confrontation as over.
The implication was that Israel had ceased its reprisal attacks in the Strip because Hamas had halted rocket attacks on Israeli communities, but did not see itself obligated to a truce.
Leaders of Israeli cities and towns near the Gaza border on Friday criticized the government over the apparent ceasefire with Hamas and called for a long-term solution.

Hamas’s announcement of a truce late Thursday came after a 12-hour lull in fighting, following two days that saw the heaviest exchange of Palestinian rocket fire and reprisal Israeli airstrikes since the 2014 Gaza war.
Hamas said a ceasefire had been reached “on the basis of mutual calm,” and had gone into effect at midnight on Thursday. It said the deal was mediated by Egypt and other regional players. Israel denied there was a truce, but a senior Israeli official told Israel Radio that “quiet would be met with quiet.” There were no instances of violence reported along the border overnight Thursday-Friday.
Hamas, an Islamist terrorist organization that seeks to destroy Israel, seized control of the Gaza Strip in 2007.

Thai AirAsia X doubles Seoul service
By Mark Elliott On Aug 22, 2016
Thai AirAsia X has announced plans to double the frequency of its Bangkok-Seoul flights for the upcoming high season.
From 30 October 2016 to 25 March 2017, the low-cost carrier will operate a second daily flight on the route, adding more than 2,500 seats each week in each direction.
The new service will depart Bangkok’s Don Mueang Airport daily at 0815 and arrive at Seoul’s Incheon International Airport at 1520. The return flight then leaves the Korean capital at 1625 and arrives back in Bangkok at 2015.

These flights will complement Thai AirAsia X’s existing 0155 departures from Bangkok and 1115 return flights from Seoul, and both daily flights will be operated using a 366-seat, two-class Airbus A330-300 aircraft.
Nadda Buranasiri, CEO of Thai AirAsia X, explained that the second flight is being added “in anticipation of increased demand during the upcoming travel season, especially for Thai travellers who want to visit South Korea in the autumn and winter”.
The Korea Tourism Organization (KTO) welcomed the decision.
“South Korea is one of Thailand’s most popular destinations for tourism, especially due to the success of K-pop and K-dramas among the Thai youths, which has spurred more of them to visit the country on their own,” said Lee Woong, director of the KTO’s Bangkok office.
“Our organisation congratulates and thanks Thai AirAsia X for increasing its flights from Bangkok to Seoul to twice daily to accommodate the higher number of Thai travellers to South Korea expected later this year.”
In the first half of 2016, more than 248,000 Thai nationals travelled to South Korea, up 13.8% compared to the same period last year. Thai AirAsia X revealed that its load factor on the Bangkok-Seoul route averaged 91% during the period.

Selma Blair says she felt 'relief' after MS diagnosis

Feb. 26 (UPI) -- Selma Blair says she felt "relief" after being diagnosed with multiple sclerosis in 2018.
The 46-year-old actress discussed her experience with the disease, which affects the central nervous system, in an interview during Tuesday's episode of Good Morning America.
Blair told host Robin Roberts she was in the midst of a flare-up and experiencing spasmodic dysphonia, a neurological disorder affecting the voice.
"I am doing very well," she said. "I am very happy to see you. Being able to just put out what being in the middle of an aggressive form of multiple sclerosis is like."
The Cruel Intentions star recalled her emotional reaction to being diagnosed with MS in August.
"I cried," she said. "I had tears. They weren't tears of panic. They were tears of knowing that I now had to give in to a body that had loss of control and there was some relief in that."
Blair said she experienced years of pain and other symptoms prior to her diagnosis but was "not taken seriously by doctors."
"Ever since my son was born I was in an MS flare-up and didn't know, and I was giving it everything to seem normal," she said. "I was ashamed and I was doing the best I could ... so when I got the diagnosis, I cried with some relief."

Blair has been in touch with actor Michael J. Fox, who is diagnosed with Parkinson's disease, and said the actor gives her hope. She said her doctor is optimistic about her prognosis, although she's not taking her health for granted.
"The doctor I saw, he said within a year I could have -- at the time he said -- 90 percent of my abilities back. So this is to say, let's meet again next year and see if I'm better," the star said.
Blair went public about her MS diagnosis in August. She returned to the red carpet Sunday at the Oscars ceremony in Los Angeles.

NYPD: Missing YouTuber Etika's body pulled from East River
Darryl Coote
June 26 (UPI) -- Desmond Amofah, a popular YouTuber who went by the name "Etika," has been found dead almost a week after he was reported missing, authorities said.
The New York Police Department said June 20 that Amofah, 29, was last heard from around 8 p.m. the day before, shortly after posting a video online that "has many people concerned."
A department spokesperson said authorities pulled his body from the East River on Monday evening after having received a 911 call about a body seen floating in the water.
"We regret to inform that Desmond Amofah aka Etika has been found deceased," the NYPD said on Twitter Tuesday.

Amofah, who made videos about video games and video game culture, went missing shortly after posting an 8-minute video during which he expressed suicidal thoughts, the New York Post reported.
"I'm sorry for leaving such a stained legacy," he said in the video, which has since been deleted from his account. "I hope that my story maybe helps to make YouTube a better place in the future where people know boundaries and limits and how far things should go."

Aug. 1, 2014 / 12:49 PM
Five-minute video visualizes history of human culture
The video has been dubbed a "macroscopic view of cultural history."
Brooks Hays
DALLAS, Aug. 1 (UPI) -- Maximilian Schich, an art historian at the University of Texas at Dallas, has condensed 2,600 years of so-called 'human cultural history,' from 600 BCE to 2012, into a five minute animation.
He did so by plotting the birth and death points of notable figures -- some 120,000 of them. It's a dubious mix of supposed cultural history makers, including the antiquated, like Solon, the Greek lawmaker and poet born 637 BCE in Athens, and the (arguably) irrelevant, like Jett Travolta, son of actor John Travolta, who died in 2009 at the age of 16 after having a seizure in the Bahamas.
Schich and his colleagues sourced their data from Google-owned knowledge base, Freebase, which according to its homepage is a "community-curated database of well-known people, places, and things."
The animation is sure to make happy the many defenders of Western civilization and its cultural canons, but it's clear that large swaths of the world are left ignored by Schich's Eurocentric methodology.

Viewed within the context of a Western bias, the research -- dubbed a "macroscopic view of cultural history" -- does offer some unique insights, pinpointing the precise moment (1789) when Paris became the cultural epicenter of the world, leaving Rome on the decline.
Schich said many cultural historians hone in on specific regions and time periods. "But our data allow them to see unexpected correlations between obscure events never considered historically important and shifts in migration," he explained -- unexpected correlations like the fact that more architects than artists died during the French revolution.

Protesters occupy Taiwan Parliament over China trade deal
Mar 24, 2014 | News in Brief | 0 |
Hundreds of students and activists opposed to a trade deal with China have occupied Taiwan’s parliament and defied policy efforts to evict them. The protesters in the parliament say that the agreement with China would hurt Taiwan’s economy and leave it vulnerable to pressure from Beijing. The trade deal would allow China and Taiwan to invest more freely in each other’s service market. China and Taiwan were split at the end of the Chinese civil war in 1949 and China regards Taiwan as part of its territory, claiming its sovereignty over the region. Also, China is Taiwan’s biggest trading partner and, in recent years, ties between the two have improved. Critics fear that the Trade Deal signed this time will make Taiwan increasingly integrate with China and threaten Taiwan’s independence.

Sample records for national digital seismic
Ghana's experience in the establishment of a national digital seismic network observatory
Ahulu, Sylvanus; Danuor, Sylvester Kojo
The Government of Ghana has established a National Digital Seismic Network Observatory in Ghana with the aim of monitoring events such as earthquakes, blasts from mining and quarrying, nuclear tests, etc. The Digital Observatory was commissioned on 19 December 2012, and was dedicated to Geosciences in Ghana. Previously Ghana did not have any operational, digital seismic network acquisition system with the capability of monitoring and analysing data for planning and research purposes. The Ghana Geological Survey has been monitoring seismic events with an analogue system which was not efficient and does not deliver real-time data. Hence, the importance of setting up the National Digital Seismic Network System which would enable the Geological Survey to constantly monitor, manage and coordinate both natural and man-made seismic activities in the country and around the globe, to some extent on real-time basis. The Network System is made up of six remote digital stations that transmit data via satellite to the central observatory. Sensors used are 3× Trillium Compact and 3× Trillium 120PA with Trident digitizers. The department has also acquired strong motion equipment: Titan accelerometers with Taurus digitizers from Nanometrics. Three of each of these instruments have been installed at the Akosombo and Kpong hydrodams, and also at the Weija water supply dam. These instruments are used to monitor dams. The peak ground acceleration (PGA) values established from the analysed data from the accelerometers will be used to retrofit or carry out maintenance work of the dam structures to avoid collapse. Apart from these, the observatory also assesses and analyses seismic waveforms relevant to its needs from the Global Seismographic Network (GSN) system operated by the US Geological Survey. The Ghana Geological Survey, through its Seismic Network Observatory makes data available to its stakeholder institutions for earthquake disaster mitigation; reports on all aspects of
Digital recovery, modification, and analysis of Tetra Tech seismic horizon mapping, National Petroleum Reserve Alaska (NPRA), northern Alaska
Saltus, R.W.; Kulander, Christopher S.; Potter, Christopher J.
We have digitized, modified, and analyzed seismic interpretation maps of 12 subsurface stratigraphic horizons spanning portions of the National Petroleum Reserve in Alaska (NPRA). These original maps were prepared by Tetra Tech, Inc., based on about 15,000 miles of seismic data collected from 1974 to 1981. We have also digitized interpreted faults and seismic velocities from Tetra Tech maps. The seismic surfaces were digitized as two-way travel time horizons and converted to depth using Tetra Tech seismic velocities. The depth surfaces were then modified by long-wavelength corrections based on recent USGS seismic re-interpretation along regional seismic lines. We have developed and executed an algorithm to identify and calculate statistics on the area, volume, height, and depth of closed structures based on these seismic horizons. These closure statistics are tabulated and have been used as input to oil and gas assessment calculations for the region. Directories accompanying this report contain basic digitized data, processed data, maps, tabulations of closure statistics, and software relating to this project.
National Seismic Network of Georgia
Tumanova, N.; Kakhoberashvili, S.; Omarashvili, V.; Tserodze, M.; Akubardia, D.
Georgia, as a part of the Southern Caucasus, is tectonically active and structurally complex region. It is one of the most active segments of the Alpine-Himalayan collision belt. The deformation and the associated seismicity are due to the continent-continent collision between the Arabian and Eurasian plates. Seismic Monitoring of country and the quality of seismic data is the major tool for the rapid response policy, population safety, basic scientific research and in the end for the sustainable development of the country. National Seismic Network of Georgia has been developing since the end of 19th century. Digital era of the network started from 2003. Recently continuous data streams from 25 stations acquired and analyzed in the real time. Data is combined to calculate rapid location and magnitude for the earthquake. Information for the bigger events (Ml>=3.5) is simultaneously transferred to the website of the monitoring center and to the related governmental agencies. To improve rapid earthquake location and magnitude estimation the seismic network was enhanced by installing additional 7 new stations. Each new station is equipped with coupled Broadband and Strong Motion seismometers and permanent GPS system as well. To select the sites for the 7 new base stations, we used standard network optimization techniques. To choose the optimal sites for new stations we've taken into account geometry of the existed seismic network, topographic conditions of the site. For each site we studied local geology (Vs30 was mandatory for each site), local noise level and seismic vault construction parameters. Due to the country elevation, stations were installed in the high mountains, no accessible in winter due to the heavy snow conditions. To secure online data transmission we used satellite data transmission as well as cell data network coverage from the different local companies. As a result we've already have the improved earthquake location and event magnitudes. We
The Berkeley Digital Seismic Network
Romanowicz, B.; Dreger, D.; Neuhauser, D.; Karavas, W.; Hellweg, M.; Uhrhammer, R.; Lombard, P.; Friday, J.; Lellinger, R.; Gardner, J.; McKenzie, M. R.; Bresloff, C.
Since it began monitoring earthquakes in northern California 120 years ago, the Berkeley Seismological Laboratory (BSL) has been striving to produce the highest quality and most complete seismic data possible in the most modern way. This goal has influenced choices in instrumentation, installation and telemetry, as well as the investment in expertise and manpower. Since the transition to broadband (BB) instrumentation in the mid- 1980s and to a fully digitally telemetered network in the early 1990s, we have continued these efforts. Each of our 25 BB installations includes three component BB seismometers (STS-1s or STS-2) and digital accelerometers to capture the full range of ground motion from distant teleseisms to large, nearby earthquakes (almost 250 dB). The ground motion is recorded on-site by 24 bit dataloggers. Additional environmental parameters, such as temperature and pressure, are also monitored continuously. Many stations record also C-GPS data that is transmitted continuously to the BSL via shared real-time telemetry. The BDSN's first stations were installed in abandoned mines. In the last 15 years, we developed installations using buried shipping containers to reduce environmental noise and provide security and easy access to the equipment. Data are transmitted in real-time at several sampling rates to one or more processing centers, using frame relay, radio, microwave, and/or satellite. Each site has 7-30 days of onsite data storage to guard against data loss during telemetry outages. Each station is supplied with backup batteries to provide power for 3 days. The BDSN real-time data acquisition, earthquake analysis and archiving computers are housed in a building built to "emergency grade" seismic standards, with air conditioning and power backed up by a UPS and a large generator. Data latency and power are monitored by automated processes that alert staff via pager and email. Data completeness and timing quality are automatically assessed on a daily
The Italian National Seismic Network
Michelini, Alberto
The Italian National Seismic Network is composed by about 400 stations, mainly broadband, installed in the Country and in the surrounding regions. About 110 stations feature also collocated strong motion instruments. The Centro Nazionale Terremoti, (National Earthquake Center), CNT, has installed and operates most of these stations, although a considerable number of stations contributing to the INGV surveillance has been installed and is maintained by other INGV sections (Napoli, Catania, Bologna, Milano) or even other Italian or European Institutions. The important technological upgrades carried out in the last years has allowed for significant improvements of the seismic monitoring of Italy and of the Euro-Mediterranean Countries. The adopted data transmission systems include satellite, wireless connections and wired lines. The Seedlink protocol has been adopted for data transmission. INGV is a primary node of EIDA (European Integrated Data Archive) for archiving and distributing, continuous, quality checked data. The data acquisition system was designed to accomplish, in near-real-time, automatic earthquake detection and hypocenter and magnitude determination (moment tensors, shake maps, etc.). Database archiving of all parametric results are closely linked to the existing procedures of the INGV seismic monitoring environment. Overall, the Italian earthquake surveillance service provides, in quasi real-time, hypocenter parameters which are then revised routinely by the analysts of the Bollettino Sismico Nazionale. The results are published on the web page http://cnt.rm.ingv.it/ and are publicly available to both the scientific community and the the general public. This presentation will describe the various activities and resulting products of the Centro Nazionale Terremoti. spanning from data acquisition to archiving, distribution and specialised products.
Bulgarian National Digital Seismological Network
Dimitrova, L.; Solakov, D.; Nikolova, S.; Stoyanov, S.; Simeonova, S.; Zimakov, L. G.; Khaikin, L.
The Bulgarian National Digital Seismological Network (BNDSN) consists of a National Data Center (NDC), 13 stations equipped with RefTek High Resolution Broadband Seismic Recorders - model DAS 130-01/3, 1 station equipped with Quanterra 680 and broadband sensors and accelerometers. Real-time data transfer from seismic stations to NDC is realized via Virtual Private Network of the Bulgarian Telecommunication Company. The communication interruptions don't cause any data loss at the NDC. The data are backed up in the field station recorder's 4Mb RAM memory and are retransmitted to the NDC immediately after the communication link is re-established. The recorders are equipped with 2 compact flash disks able to save more than 1 month long data. The data from the flash disks can be downloaded remotely using FTP. The data acquisition and processing hardware redundancy at the NDC is achieved by two clustered SUN servers and two Blade Workstations. To secure the acquisition, processing and data storage processes a three layer local network is designed at the NDC. Real-time data acquisition is performed using REFTEK's full duplex error-correction protocol RTPD. Data from the Quanterra recorder and foreign stations are fed into RTPD in real-time via SeisComP/SeedLink protocol. Using SeisComP/SeedLink software the NDC transfers real-time data to INGV-Roma, NEIC-USA, ORFEUS Data Center. Regional real-time data exchange with Romania, Macedonia, Serbia and Greece is established at the NDC also. Data processing is performed by the Seismic Network Data Processor (SNDP) software package running on the both Servers. SNDP includes subsystems: Real-time subsystem (RTS_SNDP) - for signal detection; evaluation of the signal parameters; phase identification and association; source estimation; Seismic analysis subsystem (SAS_SNDP) - for interactive data processing; Early warning subsystem (EWS_SNDP) - based on the first arrived P-phases. The signal detection process is performed by
Digital processing of array seismic recordings
Ryall, Alan; Birtill, John
This technical letter contains a brief review of the operations which are involved in digital processing of array seismic recordings by the methods of velocity filtering, summation, cross-multiplication and integration, and by combinations of these operations (the "UK Method" and multiple correlation). Examples are presented of analyses by the several techniques on array recordings which were obtained by the U.S. Geological Survey during chemical and nuclear explosions in the western United States. Seismograms are synthesized using actual noise and Pn-signal recordings, such that the signal-to-noise ratio, onset time and velocity of the signal are predetermined for the synthetic record. These records are then analyzed by summation, cross-multiplication, multiple correlation and the UK technique, and the results are compared. For all of the examples presented, analysis by the non-linear techniques of multiple correlation and cross-multiplication of the traces on an array recording are preferred to analyses by the linear operations involved in summation and the UK Method.
USGS National Seismic Hazard Maps
Frankel, A.D.; Mueller, C.S.; Barnhard, T.P.; Leyendecker, E.V.; Wesson, R.L.; Harmsen, S.C.; Klein, F.W.; Perkins, D.M.; Dickman, N.C.; Hanson, S.L.; Hopper, M.G.
The U.S. Geological Survey (USGS) recently completed new probabilistic seismic hazard maps for the United States, including Alaska and Hawaii. These hazard maps form the basis of the probabilistic component of the design maps used in the 1997 edition of the NEHRP Recommended Provisions for Seismic Regulations for New Buildings and Other Structures, prepared by the Building Seismic Safety Council arid published by FEMA. The hazard maps depict peak horizontal ground acceleration and spectral response at 0.2, 0.3, and 1.0 sec periods, with 10%, 5%, and 2% probabilities of exceedance in 50 years, corresponding to return times of about 500, 1000, and 2500 years, respectively. In this paper we outline the methodology used to construct the hazard maps. There are three basic components to the maps. First, we use spatially smoothed historic seismicity as one portion of the hazard calculation. In this model, we apply the general observation that moderate and large earthquakes tend to occur near areas of previous small or moderate events, with some notable exceptions. Second, we consider large background source zones based on broad geologic criteria to quantify hazard in areas with little or no historic seismicity, but with the potential for generating large events. Third, we include the hazard from specific fault sources. We use about 450 faults in the western United States (WUS) and derive recurrence times from either geologic slip rates or the dating of pre-historic earthquakes from trenching of faults or other paleoseismic methods. Recurrence estimates for large earthquakes in New Madrid and Charleston, South Carolina, were taken from recent paleoliquefaction studies. We used logic trees to incorporate different seismicity models, fault recurrence models, Cascadia great earthquake scenarios, and ground-motion attenuation relations. We present disaggregation plots showing the contribution to hazard at four cities from potential earthquakes with various magnitudes and
2008 United States National Seismic Hazard Maps
Petersen, M.D.; ,
The U.S. Geological Survey recently updated the National Seismic Hazard Maps by incorporating new seismic, geologic, and geodetic information on earthquake rates and associated ground shaking. The 2008 versions supersede those released in 1996 and 2002. These maps are the basis for seismic design provisions of building codes, insurance rate structures, earthquake loss studies, retrofit priorities, and land-use planning. Their use in design of buildings, bridges, highways, and critical infrastructure allows structures to better withstand earthquake shaking, saving lives and reducing disruption to critical activities following a damaging event. The maps also help engineers avoid costs from over-design for unlikely levels of ground motion.

Design and development of digital seismic amplifier recorder
Samsidar, Siti Alaa; Afuar, Waldy; Handayani, Gunawan, E-mail: gunawanhandayani@gmail.com
A digital seismic recording is a recording technique of seismic data in digital systems. This method is more convenient because it is more accurate than other methods of seismic recorders. To improve the quality of the results of seismic measurements, the signal needs to be amplified to obtain better subsurface images. The purpose of this study is to improve the accuracy of measurement by amplifying the input signal. We use seismic sensors/geophones with a frequency of 4.5 Hz. The signal is amplified by means of 12 units of non-inverting amplifier. The non-inverting amplifier using IC 741 with the resistor values 1KΩmore » and 1MΩ. The amplification results were 1,000 times. The results of signal amplification converted into digital by using the Analog Digital Converter (ADC). Quantitative analysis in this study was performed using the software Lab VIEW 8.6. The Lab VIEW 8.6 program was used to control the ADC. The results of qualitative analysis showed that the seismic conditioning can produce a large output, so that the data obtained is better than conventional data. This application can be used for geophysical methods that have low input voltage such as microtremor application.« less
Modernization of the Slovenian National Seismic Network
Vidrih, R.; Godec, M.; Gosar, A.; Sincic, P.; Tasic, I.; Zivcic, M.
The Environmental Agency of the Republic of Slovenia, the Seismology Office is responsible for the fast and reliable information about earthquakes, originating in the area of Slovenia and nearby. In the year 2000 the project Modernization of the Slovenian National Seismic Network started. The purpose of a modernized seismic network is to enable fast and accurate automatic location of earthquakes, to determine earthquake parameters and to collect data of local, regional and global earthquakes. The modernized network will be finished in the year 2004 and will consist of 25 Q730 remote broadband data loggers based seismic station subsystems transmitting in real-time data to the Data Center in Ljubljana, where the Seismology Office is located. The remote broadband station subsystems include 16 surface broadband seismometers CMG-40T, 5 broadband seismometers CMG-40T with strong motion accelerographs EpiSensor, 4 borehole broadband seismometers CMG-40T, all with accurate timing provided by GPS receivers. The seismic network will cover the entire Slovenian territory, involving an area of 20,256 km2. The network is planned in this way; more seismic stations will be around bigger urban centres and in regions with greater vulnerability (NW Slovenia, Krsko Brezice region). By the end of the year 2002, three old seismic stations were modernized and ten new seismic stations were built. All seismic stations transmit data to UNIX-based computers running Antelope system software. The data is transmitted in real time using TCP/IP protocols over the Goverment Wide Area Network . Real-time data is also exchanged with seismic networks in the neighbouring countries, where the data are collected from the seismic stations, close to the Slovenian border. A typical seismic station consists of the seismic shaft with the sensor and the data acquisition system and, the service shaft with communication equipment (modem, router) and power supply with a battery box. which provides energy in case
Improved Seismic Acquisition System and Data Processing for the Italian National Seismic Network
Badiali, L.; Marcocci, C.; Mele, F.; Piscini, A.
A new system for acquiring and processing digital signals has been developed in the last few years at the Istituto Nazionale di Geofisica e Vulcanologia (INGV). The system makes extensive use of the internet communication protocol standards such as TCP and UDP which are used as the transport highway inside the Italian network, and possibly in a near future outside, to share or redirect data among processes. The Italian National Seismic Network has been working for about 18 years equipped with vertical short period seismometers and transmitting through analog lines, to the computer center in Rome. We are now concentrating our efforts on speeding the migration towards a fully digital network based on about 150 stations equipped with either broad band or 5 seconds sensors connected to the data center partly through wired digital communication and partly through satellite digital communication. The overall process is layered through intranet and/or internet. Every layer gathers data in a simple format and provides data in a processed format, ready to be distributed towards the next layer. The lowest level acquires seismic data (raw waveforms) coming from the remote stations. It handshakes, checks and sends data in LAN or WAN according to a distribution list where other machines with their programs are waiting for. At the next level there are the picking procedures, or "pickers", on a per instrument basis, looking for phases. A picker spreads phases, again through the LAN or WAN and according to a distribution list, to one or more waiting locating machines tuned to generate a seismic event. The event locating procedure itself, the higher level in this stack, can exchange information with other similar procedures. Such a layered and distributed structure with nearby targets allows other seismic networks to join the processing and data collection of the same ongoing event, creating a virtual network larger than the original one. At present we plan to cooperate with other
Seismic hazard in the Nation's breadbasket
Boyd, Oliver; Haller, Kathleen; Luco, Nicolas; Moschetti, Morgan P.; Mueller, Charles; Petersen, Mark D.; Rezaeian, Sanaz; Rubinstein, Justin L.
The USGS National Seismic Hazard Maps were updated in 2014 and included several important changes for the central United States (CUS). Background seismicity sources were improved using a new moment-magnitude-based catalog; a new adaptive, nearest-neighbor smoothing kernel was implemented; and maximum magnitudes for background sources were updated. Areal source zones developed by the Central and Eastern United States Seismic Source Characterization for Nuclear Facilities project were simplified and adopted. The weighting scheme for ground motion models was updated, giving more weight to models with a faster attenuation with distance compared to the previous maps. Overall, hazard changes (2% probability of exceedance in 50 years, across a range of ground-motion frequencies) were smaller than 10% in most of the CUS relative to the 2008 USGS maps despite new ground motion models and their assigned logic tree weights that reduced the probabilistic ground motions by 5–20%.
Instrumentation Guidelines for the Advanced National Seismic System
Working Group on Instrumentation, Siting
This document provides guidelines for the seismic-monitoring instrumentation used by long-term earthquake-monitoring stations that will sense ground motion, digitize and store the resulting signals in a local data acquisition unit, and optionally transmit these digital data. These guidelines are derived from specifications and requirements for data needed to address the nation's emergency response, engineering, and scientific needs as identified in U.S. Geological Survey Circular 1188 (1999). Data needs are discussed in terms of national, regional, and urban scales of monitoring in section 3. Functional performance specifications for instrumentation are introduced in section 4.3 and discussed in detail in section 6 in terms of instrument classes and definitions described in section 5. System aspects and testing recommendations are discussed in sections 7 and 8, respectively. Although U.S. Geological Survey Circular 1188 (1999) recommends that the Advanced National Seismic System (ANSS) include portable instrumentation, performance specifications for this element are not specifically addressed in this document. Nevertheless, these guidelines are largely applicable to portable instrumentation. Volcano monitoring instrumentation is also beyond the scope of this document. Guidance for ANSS structural-response monitoring is discussed briefly herein but details are deferred to the ANSS document by the ANSS Structural Response Monitoring Committee (U.S. Geological Survey, 2005). Aspects of station planning, siting, and installation other than instrumentation are beyond the scope of this document.
Introduction of digital object identifiers (DOI) for seismic networks
Evans, Peter; Strollo, Angelo; Clark, Adam; Ahern, Tim; Newman, Rob; Clinton, John; Pequegnat, Catherine; Pedersen, Helle
Proper attribution for scientific source data is important in promoting transparency and recognising the role of data providers in science. Data sets such as those produced by seismic networks now need to be citable and permanently locatable for research users. Recently the EIDA and IRIS-DMC communities have worked together on development of methods for generation, maintenance and promotion of persistent identifiers for seismic networks. This resulted in a 2014 Recommendation by the International Federation of Digital Seismograph Networks (FDSN) on the use of Digital Object Identifiers (DOI) for seismic networks. These can be cited equivalently to scientific papers, and tools such as DataCite allow the tracking of citations to these datasets. The GEOFON, IRIS and RESIF data centres have now begun to roll-out of these seismic network DOIs. This has involved working with principal investigators to prepare metadata consistent with the FDSN recommendation, preparation of landing pages, and changes to the web sites to promote DOIs where available. This has involved preparing improved descriptions of the data (metadata) and clarifying how individuals and institutions should best be recognised for their contributions to making the data available. We illustrate this process for a few representative networks. We will be in contact with additional network operators to help them establish DOIs for their networks in future.
A method for producing digital probabilistic seismic landslide hazard maps

The 1994 Northridge, California, earthquake is the first earthquake for which we have all of the data sets needed to conduct a rigorous regional analysis of seismic slope instability. These data sets include: (1) a comprehensive inventory of triggered landslides, (2) about 200 strong-motion records of the mainshock, (3) 1:24 000-scale geologic mapping of the region, (4) extensive data on engineering properties of geologic units, and (5) high-resolution digital elevation models of the topography. All of these data sets have been digitized and rasterized at 10 m grid spacing using ARC/INFO GIS software on a UNIX computer. Combining these data sets in a dynamic model based on Newmark's permanent-deformation (sliding-block) analysis yields estimates of coseismic landslide displacement in each grid cell from the Northridge earthquake. The modeled displacements are then compared with the digital inventory of landslides triggered by the Northridge earthquake to construct a probability curve relating predicted displacement to probability of failure. This probability function can be applied to predict and map the spatial variability in failure probability in any ground-shaking conditions of interest. We anticipate that this mapping procedure will be used to construct seismic landslide hazard maps that will assist in emergency preparedness planning and in making rational decisions regarding development and construction in areas susceptible to seismic slope failure. ?? 2000 Elsevier Science B.V.

The Advanced National Seismic System; management and implementation
Benz, H.M.; Shedlock, K.M.; Buland, R.P.
What is the Advanced National Seismic System? The Advanced National Seismic System (ANSS) is designed to organize, modernize, and standardize operations of seismic networks in the United States to improve the Nation’s ability to respond effectively to damaging earthquakes, volcanoes, and tsunamis. To achieve this, the ANSS will link more than 7,000 national, regional and urban monitoring stations in real time
A National Solar Digital Observatory
Hill, F.
The continuing development of the Internet as a research tool, combined with an improving funding climate, has sparked new interest in the development of Internet-linked astronomical data bases and analysis tools. Here I outline a concept for a National Solar Digital Observatory (NSDO), a set of data archives and analysis tools distributed in physical location at sites which already host such systems. A central web site would be implemented from which a user could search all of the component archives, select and download data, and perform analyses. Example components include NSO's Digital Library containing its synoptic and GONG data, and the forthcoming SOLIS archive. Several other archives, in various stages of development, also exist. Potential analysis tools include content-based searches, visualized programming tools, and graphics routines. The existence of an NSDO would greatly facilitate solar physics research, as a user would no longer need to have detailed knowledge of all solar archive sites. It would also improve public outreach efforts. The National Solar Observatory is operated by AURA, Inc. under a cooperative agreement with the National Science Foundation.
DigiSeis—A software component for digitizing seismic signals using the PC sound card
Amin Khan, Khalid; Akhter, Gulraiz; Ahmad, Zulfiqar
An innovative software-based approach to develop an inexpensive experimental seismic recorder is presented. This approach requires no hardware as the built-in PC sound card is used for digitization of seismic signals. DigiSeis, an ActiveX component is developed to capture the digitized seismic signals from the sound card and deliver them to applications for processing and display. A seismic recorder application software SeisWave is developed over this component, which provides real-time monitoring and display of seismic events picked by a pair of external geophones. This recorder can be used as an educational aid for conducting seismic experiments. It can also be connected with suitable seismic sensors to record earthquakes. The software application and the ActiveX component are available for download. This component can be used to develop seismic recording applications according to user specific requirements.
Origins of a national seismic system in the United States
Filson, John R.; Arabasz, Walter J.
This historical review traces the origins of the current national seismic system in the United States, a cooperative effort that unifies national, regional, and local�scale seismic monitoring within the structure of the Advanced National Seismic System (ANSS). The review covers (1) the history and technological evolution of U.S. seismic networks leading up to the 1990s, (2) factors that made the 1960s and 1970s a watershed period for national attention to seismology, earthquake hazards, and seismic monitoring, (3) genesis of the vision of a national seismic system during 1980–1983, (4) obstacles and breakthroughs during 1984–1989, (5) consensus building and convergence during 1990–1992, and finally (6) the two�step realization of a national system during 1993–2000. Particular importance is placed on developments during the period between 1980 and 1993 that culminated in the adoption of a charter for the Council of the National Seismic System (CNSS)—the foundation for the later ANSS. Central to this story is how many individuals worked together toward a common goal of a more rational and sustainable approach to national earthquake monitoring in the United States. The review ends with the emergence of ANSS during 1999 and 2000 and its statutory authorization by Congress in November 2000.
Seismic source characterization for the 2014 update of the U.S. National Seismic Hazard Model
Moschetti, Morgan P.; Powers, Peter; Petersen, Mark D.; Boyd, Oliver; Chen, Rui; Field, Edward H.; Frankel, Arthur; Haller, Kathleen; Harmsen, Stephen; Mueller, Charles S.; Wheeler, Russell; Zeng, Yuehua
We present the updated seismic source characterization (SSC) for the 2014 update of the National Seismic Hazard Model (NSHM) for the conterminous United States. Construction of the seismic source models employs the methodology that was developed for the 1996 NSHM but includes new and updated data, data types, source models, and source parameters that reflect the current state of knowledge of earthquake occurrence and state of practice for seismic hazard analyses. We review the SSC parameterization and describe the methods used to estimate earthquake rates, magnitudes, locations, and geometries for all seismic source models, with an emphasis on new source model components. We highlight the effects that two new model components—incorporation of slip rates from combined geodetic-geologic inversions and the incorporation of adaptively smoothed seismicity models—have on probabilistic ground motions, because these sources span multiple regions of the conterminous United States and provide important additional epistemic uncertainty for the 2014 NSHM.
An assessment of seismic monitoring in the United States; requirement for an Advanced National Seismic System
This report assesses the status, needs, and associated costs of seismic monitoring in the United States. It sets down the requirement for an effective, national seismic monitoring strategy and an advanced system linking national, regional, and urban monitoring networks. Modernized seismic monitoring can provide alerts of imminent strong earthquake shaking; rapid assessment of distribution and severity of earthquake shaking (for use in emergency response); warnings of a possible tsunami from an offshore earthquake; warnings of volcanic eruptions; information for correctly characterizing earthquake hazards and for improving building codes; and data on response of buildings and structures during earthquakes, for safe, cost-effective design, engineering, and construction practices in earthquake-prone regions.
Regional seismic lines reprocessed using post-stack processing techniques; National Petroleum Reserve, Alaska
Miller, John J.; Agena, W.F.; Lee, M.W.; Zihlman, F.N.; Grow, J.A.; Taylor, D.J.; Killgore, Michele; Oliver, H.L.
This CD-ROM contains stacked, migrated, 2-Dimensional seismic reflection data and associated support information for 22 regional seismic lines (3,470 line-miles) recorded in the National Petroleum Reserve ? Alaska (NPRA) from 1974 through 1981. Together, these lines constitute about one-quarter of the seismic data collected as part of the Federal Government?s program to evaluate the petroleum potential of the Reserve. The regional lines, which form a grid covering the entire NPRA, were created by combining various individual lines recorded in different years using different recording parameters. These data were reprocessed by the USGS using modern, post-stack processing techniques, to create a data set suitable for interpretation on interactive seismic interpretation computer workstations. Reprocessing was done in support of ongoing petroleum resource studies by the USGS Energy Program. The CD-ROM contains the following files: 1) 22 files containing the digital seismic data in standard, SEG-Y format; 2) 1 file containing navigation data for the 22 lines in standard SEG-P1 format; 3) 22 small scale graphic images of each seismic line in Adobe Acrobat? PDF format; 4) a graphic image of the location map, generated from the navigation file, with hyperlinks to the graphic images of the seismic lines; 5) an ASCII text file with cross-reference information for relating the sequential trace numbers on each regional line to the line number and shotpoint number of the original component lines; and 6) an explanation of the processing used to create the final seismic sections (this document). The SEG-Y format seismic files and SEG-P1 format navigation file contain all the information necessary for loading the data onto a seismic interpretation workstation.
United States National Seismic Hazard Maps
The U.S. Geological Survey?s maps of earthquake shaking hazards provide information essential to creating and updating the seismic design provisions of building codes and insurance rates used in the United States. Periodic revisions of these maps incorporate the results of new research. Buildings, bridges, highways, and utilities built to meet modern seismic design provisions are better able to withstand earthquakes, not only saving lives but also enabling critical activities to continue with less disruption. These maps can also help people assess the hazard to their homes or places of work and can also inform insurance rates.
Geothermal Induced Seismicity National Environmental Policy Act Review
Levine, Aaron L; Cook, Jeffrey J; Beckers, Koenraad J
In 2016, the U.S. Bureau of Land Management (BLM) contracted with the National Renewable Energy Laboratory (NREL) to assist the BLM in developing and building upon tools to better understand and evaluate induced seismicity caused by geothermal projects. This review of NEPA documents for four geothermal injection or EGS projects reveals the variety of approaches to analyzing and mitigating induced seismicity. With the exception of the Geysers, where induced seismicity has been observed and monitored for an extended period of time due to large volumes of water being piped in to recharge the hydrothermal reservoir, induced seismicity caused by geothermalmore » projects is a relative new area of study. As this review highlights, determining the level of mitigation required for induced seismic events has varied based on project location, when the review took place, whether the project utilized the International Energy Agency or DOE IS protocols, and the federal agency conducting the review. While the NEPA reviews were relatively consistent for seismic monitoring and historical evaluation of seismic events near the project location, the requirements for public outreach and mitigation for induced seismic events once stimulation has begun varied considerably between the four projects. Not all of the projects were required to notify specific community groups or local government entities before beginning the project, and only one of the reviews specifically stated the project proponent would hold meetings with the public to answer questions or address concerns.« less
A National Consideration of Digital Equity
Davis, T.; Fuller, M.; Jackson, S.; Pittman, J.; Sweet, J.
The National Center for Education Statistics (NCES) report, "Computer and Internet Use by Students in 2003" (NCES, 2006) reveals that the digital divide continues to exist, particularly along demographic and socioeconomic lines. Though an exact definition remains elusive, the term "digital divide" generally refers to the…
The seismic project of the National Tsunami Hazard Mitigation Program
Oppenheimer, D.H.; Bittenbinder, A.N.; Bogaert, B.M.; Buland, R.P.; Dietz, L.D.; Hansen, R.A.; Malone, S.D.; McCreery, C.S.; Sokolowski, T.J.; Whitmore, P.M.; Weaver, C.S.
In 1997, the Federal Emergency Management Agency (FEMA), National Oceanic and Atmospheric Administration (NOAA), U.S. Geological Survey (USGS), and the five western States of Alaska, California, Hawaii, Oregon, and Washington joined in a partnership called the National Tsunami Hazard Mitigation Program (NTHMP) to enhance the quality and quantity of seismic data provided to the NOAA tsunami warning centers in Alaska and Hawaii. The NTHMP funded a seismic project that now provides the warning centers with real-time seismic data over dedicated communication links and the Internet from regional seismic networks monitoring earthquakes in the five western states, the U.S. National Seismic Network in Colorado, and from domestic and global seismic stations operated by other agencies. The goal of the project is to reduce the time needed to issue a tsunami warning by providing the warning centers with high-dynamic range, broadband waveforms in near real time. An additional goal is to reduce the likelihood of issuing false tsunami warnings by rapidly providing to the warning centers parametric information on earthquakes that could indicate their tsunamigenic potential, such as hypocenters, magnitudes, moment tensors, and shake distribution maps. New or upgraded field instrumentation was installed over a 5-year period at 53 seismic stations in the five western states. Data from these instruments has been integrated into the seismic network utilizing Earthworm software. This network has significantly reduced the time needed to respond to teleseismic and regional earthquakes. Notably, the West Coast/Alaska Tsunami Warning Center responded to the 28 February 2001 Mw 6.8 Nisqually earthquake beneath Olympia, Washington within 2 minutes compared to an average response time of over 10 minutes for the previous 18 years. ??

Site characterization of the national seismic network of Italy
Bordoni, Paola; Pacor, Francesca; Cultrera, Giovanna; Casale, Paolo; Cara, Fabrizio; Di Giulio, Giuseppe; Famiani, Daniela; Ladina, Chiara; PIschiutta, Marta; Quintiliani, Matteo
The national seismic network of Italy (Rete Sismica Nazionale, RSN) run by Istituto Nazionale di Geofisica e Vulcanologia (INGV) consists of more than 400 seismic stations connected in real time to the institute data center in order to locate earthquakes for civil defense purposes. A critical issue in the performance of a network is the characterization of site condition at the recording stations. Recently INGV has started addressing this subject through the revision of all available geological and geophysical data, the acquisition of new information by means of ad-hoc field measurements and the analysis of seismic waveforms. The main effort is towards building a database, integrated with the other INGV infrastructures, designed to archive homogeneous parameters through the seismic network useful for a complete site characterization, including housing, geological, seismological and geotechnical features as well as the site class according to the European and Italian building codes. Here we present the ongoing INGV activities.
This presentation reviews four National Environmental Policy Act of 1969 (NEPA) documents to understand how Federal agencies, including the U.S. Bureau of Land Management and Department of Energy, review and analyze the potential impacts to the human environment when funding or approving permits for enhanced geothermal system with the potential for induced seismicity.
The 2017 Maple Creek Seismic Swarm in Yellowstone National Park
Pang, G.; Hale, J. M.; Farrell, J.; Burlacu, R.; Koper, K. D.; Smith, R. B.
The University of Utah Seismograph Stations (UUSS) performs near-real-time monitoring of seismicity in the region around Yellowstone National Park in partnership with the United States Geological Survey and the National Park Service. UUSS operates and maintains 29 seismic stations with network code WY (short-period, strong-motion, and broadband) and records data from five other seismic networks—IW, MB, PB, TA, and US—to enhance the location capabilities in the Yellowstone region. A seismic catalog is produced using a conventional STA/LTA detector and single-event location techniques (Hypoinverse). On June 12, 2017, a seismic swarm began in Yellowstone National Park about 5 km east of Hebgen Lake. The swarm is adjacent to the source region of the 1959 MW 7.3 Hebgen Lake earthquake, in an area corresponding to positive Coulumb stress change from that event. As of Aug. 1, 2017, the swarm consists of 1481 earthquakes with 1 earthquake above magnitude 4, 8 earthquakes in the magnitude 3 range, 115 earthquakes in the magnitude 2 range, 469 earthquakes in the magnitude 1 range, 856 earthquakes in the magnitude 0 range, 22 earthquakes with negative magnitudes, and 10 earthquakes with no magnitude. Earthquake depths are mostly between 3 and 10 km and earthquake depth increases toward the northwest. Moment tensors for the 2 largest events (3.6 MW and 4.4. MW) show strike-slip faulting with T axes oriented NE-SW, consistent with the regional stress field. We are currently using waveform cross-correlation methods to measure differential travel times that are being used with the GrowClust program to generate high-accuracy relative relocations. Those locations will be used to identify structures in the seismicity and make inferences about the tectonic and magmatic processes causing the swarm.
Integrate urban�scale seismic hazard analyses with the U.S. National Seismic Hazard Model
Moschetti, Morgan P.; Luco, Nicolas; Frankel, Arthur; Petersen, Mark D.; Aagaard, Brad T.; Baltay, Annemarie S.; Blanpied, Michael; Boyd, Oliver; Briggs, Richard; Gold, Ryan D.; Graves, Robert; Hartzell, Stephen; Rezaeian, Sanaz; Stephenson, William J.; Wald, David J.; Williams, Robert A.; Withers, Kyle
For more than 20 yrs, damage patterns and instrumental recordings have highlighted the influence of the local 3D geologic structure on earthquake ground motions (e.g., M">M 6.7 Northridge, California, Gao et al., 1996; M">M 6.9 Kobe, Japan, Kawase, 1996; M">M 6.8 Nisqually, Washington, Frankel, Carver, and Williams, 2002). Although this and other local�scale features are critical to improving seismic hazard forecasts, historically they have not been explicitly incorporated into the U.S. National Seismic Hazard Model (NSHM, national model and maps), primarily because the necessary basin maps and methodologies were not available at the national scale. Instead,...
Incorporating induced seismicity in the 2014 United States National Seismic Hazard Model: results of the 2014 workshop and sensitivity studies
Petersen, Mark D.; Mueller, Charles S.; Moschetti, Morgan P.; Hoover, Susan M.; Rubinstein, Justin L.; Llenos, Andrea L.; Michael, Andrew J.; Ellsworth, William L.; McGarr, Arthur F.; Holland, Austin A.; Anderson, John G.
The U.S. Geological Survey National Seismic Hazard Model for the conterminous United States was updated in 2014 to account for new methods, input models, and data necessary for assessing the seismic ground shaking hazard from natural (tectonic) earthquakes. The U.S. Geological Survey National Seismic Hazard Model project uses probabilistic seismic hazard analysis to quantify the rate of exceedance for earthquake ground shaking (ground motion). For the 2014 National Seismic Hazard Model assessment, the seismic hazard from potentially induced earthquakes was intentionally not considered because we had not determined how to properly treat these earthquakes for the seismic hazard analysis. The phrases “potentially induced� and “induced� are used interchangeably in this report, however it is acknowledged that this classification is based on circumstantial evidence and scientific judgment. For the 2014 National Seismic Hazard Model update, the potentially induced earthquakes were removed from the NSHM’s earthquake catalog, and the documentation states that we would consider alternative models for including induced seismicity in a future version of the National Seismic Hazard Model. As part of the process of incorporating induced seismicity into the seismic hazard model, we evaluate the sensitivity of the seismic hazard from induced seismicity to five parts of the hazard model: (1) the earthquake catalog, (2) earthquake rates, (3) earthquake locations, (4) earthquake Mmax (maximum magnitude), and (5) earthquake ground motions. We describe alternative input models for each of the five parts that represent differences in scientific opinions on induced seismicity characteristics. In this report, however, we do not weight these input models to come up with a preferred final model. Instead, we present a sensitivity study showing uniform seismic hazard maps obtained by applying the alternative input models for induced seismicity. The final model will be released after
National Earthquake Information Center Seismic Event Detections on Multiple Scales
Patton, J.; Yeck, W. L.; Benz, H.; Earle, P. S.; Soto-Cordero, L.; Johnson, C. E.
The U.S. Geological Survey National Earthquake Information Center (NEIC) monitors seismicity on local, regional, and global scales using automatic picks from more than 2,000 near-real time seismic stations. This presents unique challenges in automated event detection due to the high variability in data quality, network geometries and density, and distance-dependent variability in observed seismic signals. To lower the overall detection threshold while minimizing false detection rates, NEIC has begun to test the incorporation of new detection and picking algorithms, including multiband (Lomax et al., 2012) and kurtosis (Baillard et al., 2014) pickers, and a new bayesian associator (Glass 3.0). The Glass 3.0 associator allows for simultaneous processing of variably scaled detection grids, each with a unique set of nucleation criteria (e.g., nucleation threshold, minimum associated picks, nucleation phases) to meet specific monitoring goals. We test the efficacy of these new tools on event detection in networks of various scales and geometries, compare our results with previous catalogs, and discuss lessons learned. For example, we find that on local and regional scales, rapid nucleation of small events may require event nucleation with both P and higher-amplitude secondary phases (e.g., S or Lg). We provide examples of the implementation of a scale-independent associator for an induced seismicity sequence (local-scale), a large aftershock sequence (regional-scale), and for monitoring global seismicity.

Local magnitude determinations for intermountain seismic belt earthquakes from broadband digital data
Pechmann, J.C.; Nava, S.J.; Terra, F.M.; Bernier, J.C.
The University of Utah Seismograph Stations (UUSS) earthquake catalogs for the Utah and Yellowstone National Park regions contain two types of size measurements: local magnitude (ML) and coda magnitude (MC), which is calibrated against ML. From 1962 through 1993, UUSS calculated ML values for southern and central Intermountain Seismic Belt earthquakes using maximum peak-to-peak (p-p) amplitudes on paper records from one to five Wood-Anderson (W-A) seismographs in Utah. For ML determinations of earthquakes since 1994, UUSS has utilized synthetic W-A seismograms from U.S. National Seismic Network and UUSS broadband digital telemetry stations in the region, which numbered 23 by the end of our study period on 30 June 2002. This change has greatly increased the percentage of earthquakes for which ML can be determined. It is now possible to determine ML for all M ???3 earthquakes in the Utah and Yellowstone regions and earthquakes as small as M <1 in some areas. To maintain continuity in the magnitudes in the UUSS earthquake catalogs, we determined empirical ML station corrections that minimize differences between MLs calculated from paper and synthetic W-A records. Application of these station corrections, in combination with distance corrections from Richter (1958) which have been in use at UUSS since 1962, produces ML values that do not show any significant distance dependence. ML determinations for the Utah and Yellowstone regions for 1981-2002 using our station corrections and Richter's distance corrections have provided a reliable data set for recalibrating the MC scales for these regions. Our revised ML values are consistent with available moment magnitude determinations for Intermountain Seismic Belt earthquakes. To facilitate automatic ML measurements, we analyzed the distribution of the times of maximum p-p amplitudes in synthetic W-A records. A 30-sec time window for maximum amplitudes, beginning 5 sec before the predicted Sg time, encompasses 95% of the
Unravelling Responses for the Canadian National Seismic Network
Mulder, T. L.
There are a number of attendant difficulties any network must deal with that range from defining the transfer function to instrument naming conventions to choices of final local file format representation. These choices ultimately result in the ease of conversion to other data formats and therefore directly impact useability. In particular, the ease of data exhange and use of established software that is dependent on standard data types is impacted. This becomes particularly critical with large (terabyte) dataset processing and when integrating external datasets into analysis procedures. Transfer functions, often referred to as instrument responses, are a key component in describing instrumentation. The transfer function describes the complete response of the seismic system. The seismic system is designed to be a linear system that can be decomposed into discrete components. Analogue or digital convolution can be represented as multiplication in the frequency domain. The two basic elements of a seismic system are the sensor and datalogger. The analogue sensor can be represented mathmatically as poles and zeroes. The datalogger can be further broken down into its discrete analogue and digital components: the preamp, A/D converter, and fir filters. The Canadian seismic network (CNSN) digitizers have an additional complication. To save telemetry band-width, the 32 bit signal from the digitizer has a transmission gain removed. The transmission gain (txgain) represents the number of the least significant bits truncated from the sample (2^txgain) after which the data is compressed and transmitted. While telemetry band-width is not the issue it was, now that many sites have ip connectivity, this user programmable transmission gain is still in use and can vary from station to station. The processes receiving the transmitted data do not restore the pre-transmission scaling, consequently the archived waveform files can vary in bit weight over time from station to station
Design and Implementation of the National Seismic Monitoring Network in the Kingdom of Bhutan
Ohmi, S.; Inoue, H.; Chophel, J.; Pelgay, P.; Drukpa, D.
Bhutan-Himalayan district is located along the plate collision zone between Indian and Eurasian plates, which is one of the most seismically active region in the world. Recent earthquakes such as M7.8 Gorkha Nepal earthquake in April 25, 2015 and M6.7 Imphal, India earthquake in January 3, 2016 are examples of felt earthquakes in Bhutan. However, there is no permanent seismic monitoring system ever established in Bhutan, whose territory is in the center of the Bhutan-Himalayan region. We started establishing permanent seismic monitoring network of minimum requirements and intensity meter network over the nation. The former is composed of six (6) observation stations in Bhutan with short period weak motion and strong motion seismometers as well as three (3) broad-band seismometers, and the latter is composed of twenty intensity meters located in every provincial government office. Obtained data are transmitted to the central processing system in the DGM office in Thimphu in real time. In this project, DGM will construct seismic vault with their own budget which is approved as the World Bank project, and Japan team assists the DGM for site survey of observation site, designing the observation vault, and designing the data telemetry system as well as providing instruments for the observation such as seismometers and digitizers. We already started the operation of the six (6) weak motion stations as well as twenty (20) intensity meter stations. Additionally, the RIMES (Regional Integrated Multi-hazard Early Warning System for Africa and Asia) is also providing eight (8) weak motion stations and we are keeping close communication to operate them as one single seismic monitoring network composed of fourteen (14) stations. This network will be definitely utilized for not only for seismic disaster mitigation of the country but also for studying the seismotectonics in the Bhutan-Himalayan region which is not yet precisely revealed due to the lack of observation data in the
Seismic Monitoring of Rock Falls in Yosemite National Park
Zimmer, V. L.; Stock, G. M.; Sitar, N.
Between 1857 and 2007, more than 600 landslide events have been documented in Yosemite National Park, with the vast majority of events occurring as rock falls in Yosemite Valley. The conditions leading to and triggering rock fall are understood in approximately 50 percent of cases, but in the other 50 percent, there were no apparent triggers. Occasionally, large rock falls have been preceded by smaller events that, in retrospect, may have been precursors. Close range seismic monitoring presents an opportunity to study the conditions leading up to rock fall, as well as the mechanics of the actual rock fall as recorded seismically. During the winter of 2007-08, we conducted a rock fall seismic monitoring feasibility study in Yosemite Valley. A station consisting of an 8 Hz geophone and an accelerometer was placed on a ledge 1000 feet above the valley floor, in a historically active rock fall area known as the Three Brothers. At least two rock falls in this area were recorded by the instrumentation and witnessed by visitors, representing the first time rock falls have been recorded with seismic instrumentation in Yosemite Valley. Significant energy was recorded in a wide frequency range, from a few Hz to approximately 150 Hz, limited by the geophone response and attenuation of the signal due to distance to the source (400 m). Furthermore, there exists a weak signal approximately 5-10 seconds before the obvious rock fall signature. We hypothesize that the weak signal represents rock fall initiation manifesting as the first blocks sliding down the cliff face, while the stronger impulses represent these blocks impacting ledges and the bottom talus field. This study demonstrated that rock fall monitoring is feasible with seismic instrumentation, and serves as the catalyst for future studies using a network of sensors for more advanced analysis.
Technical guidelines for the implementation of the Advanced National Seismic System
Committee, ANSS Technical Integration
The Advanced National Seismic System (ANSS) is a major national initiative led by the US Geological Survey that serves the needs of the earthquake monitoring, engineering, and research communities as well as national, state, and local governments, emergency response organizations, and the general public. Legislation authorizing the ANSS was passed in 2000, and low levels of funding for planning and initial purchases of new seismic instrumentation have been appropriated beginning in FY2000. When fully operational, the ANSS will be an advanced monitoring system (modern digital seismographs and accelerographs, communications networks, data collection and processing centers, and well-trained personnel) distributed across the United States that operates with high performance standards, gathers critical technical data, and effectively provides timely and reliable earthquake products, information, and services to meet the Nation’s needs. The ANSS will automatically broadcast timely and authoritative products describing the occurrence of earthquakes, earthquake source properties, the distribution of ground shaking, and, where feasible, broadcast early warnings and alerts for the onset of strong ground shaking. Most importantly, the ANSS will provide earthquake data, derived products, and information to the public, emergency responders, officials, engineers, educators, researchers, and other ANSS partners rapidly and in forms that are useful for their needs.
Preliminary deformation model for National Seismic Hazard map of Indonesia
Meilano, Irwan; Gunawan, Endra; Sarsito, Dina
Preliminary deformation model for the Indonesia’s National Seismic Hazard (NSH) map is constructed as the block rotation and strain accumulation function at the elastic half-space. Deformation due to rigid body motion is estimated by rotating six tectonic blocks in Indonesia. The interseismic deformation due to subduction is estimated by assuming coupling on subduction interface while deformation at active fault is calculated by assuming each of the fault‘s segment slips beneath a locking depth or in combination with creeping in a shallower part. This research shows that rigid body motion dominates the deformation pattern with magnitude more than 15 mm/year, except inmore » the narrow area near subduction zones and active faults where significant deformation reach to 25 mm/year.« less
Analyzing crack development pattern of masonry structure in seismic oscillation by digital photography
Zhang, Guojian; Yu, Chengxin; Ding, Xinhua
In this study, digital photography is used to monitor the instantaneous deformation of a masonry wall in seismic oscillation. In order to obtain higher measurement accuracy, the image matching-time baseline parallax method (IM-TBPM) is used to correct errors caused by the change of intrinsic and extrinsic parameters of digital cameras. Results show that the average errors of control point C5 are 0.79mm, 0.44mm and 0.96mm in X, Z and comprehensive direction, respectively. The average errors of control point C6 are 0.49mm, 0.44mm and 0.71mm in X, Z and comprehensive direction, respectively. These suggest that IM-TBPM can meet the accuracy requirements of instantaneous deformation monitoring. In seismic oscillation the middle to lower of the masonry wall develops cracks firstly. Then the shear failure occurs on the middle of masonry wall. This study provides technical basis for analyzing the crack development pattern of masonry structure in seismic oscillation and have significant implications for improved construction of masonry structures in earthquake prone areas.
Populating the Advanced National Seismic System Comprehensive Earthquake Catalog
Earle, P. S.; Perry, M. R.; Andrews, J. R.; Withers, M. M.; Hellweg, M.; Kim, W. Y.; Shiro, B.; West, M. E.; Storchak, D. A.; Pankow, K. L.; Huerfano Moreno, V. A.; Gee, L. S.; Wolfe, C. J.
The U.S. Geological Survey maintains a repository of earthquake information produced by networks in the Advanced National Seismic System with additional data from the ISC-GEM catalog and many non-U.S. networks through their contributions to the National Earthquake Information Center PDE bulletin. This Comprehensive Catalog (ComCat) provides a unified earthquake product while preserving attribution and contributor information. ComCat contains hypocenter and magnitude information with supporting phase arrival-time and amplitude measurements (when available). Higher-level products such as focal mechanisms, earthquake slip models, "Did You Feel It?" reports, ShakeMaps, PAGER impact estimates, earthquake summary posters, and tectonic summaries are also included. ComCat is updated as new events are processed and the catalog can be accesed at http://earthquake.usgs.gov/earthquakes/search/. Throughout the past few years, a concentrated effort has been underway to expand ComCat by integrating global and regional historic catalogs. The number of earthquakes in ComCat has more than doubled in the past year and it presently contains over 1.6 million earthquake hypocenters. We will provide an overview of catalog contents and a detailed description of numerous tools and semi-automated quality-control procedures developed to uncover errors including systematic magnitude biases, missing time periods, duplicate postings for the same events, and incorrectly associated events.
Seismic hazard in the South Carolina coastal plain: 2002 update of the USGS national seismic hazard maps
Cramer, C.H.; Mays, T.W.; ,
The damaging 1886 moment magnitude ???7 Charleston, South Carolina earthquake is indicative of the moderately likely earthquake activity along this portion of the Atlantic Coast. A recurrence of such an earthquake today would have serious consequences for the nation. The national seismic hazard maps produced by the U.S. Geological Survey (USGS) provide a picture of the levels of seismic hazard across the nation based on the best and most current scientific information. The USGS national maps were updated in 2002 and will become part of the International Codes in 2006. In the past decade, improvements have occurred in the scientific understanding of the nature and character of earthquake activity and expected ground motions in the central and eastern U.S. The paper summarizes the new knowledge of expected earthquake locations, magnitudes, recurrence, and ground-motion decay with distance. New estimates of peak ground acceleration and 0.2 s and 1.0 s spectral acceleration are compared with those displayed in the 1996 national maps. The 2002 maps show increased seismic hazard in much of the coastal plain of South Carolina, but a decrease in long period (1 s and greater) hazard by up to 20% at distances of over 50 km from the Charleston earthquake zone. Although the national maps do not account for the effects of local or regional sediments, deep coastal-plain sediments can significally alter expected ground shaking, particularly at long period motions where it can be 100% higher than the national maps.
Digital Seismic-Reflection Data from Eastern Rhode Island Sound and Vicinity, 1975-1980
McMullen, K.Y.; Poppe, L.J.; Soderberg, N.K.
During 1975 and 1980, the U.S. Geological Survey (USGS) conducted two seismic-reflection surveys in Rhode Island Sound (RIS) aboard the research vessel Asterias: cruise ASTR75-June surveyed eastern RIS in 1975 and cruise AST-80-6B surveyed southern RIS in 1980. Data from these surveys were recorded in analog form and archived at the USGS Woods Hole Coastal and Marine Science Center's Data Library. In response to recent interest in the geology of RIS and in an effort to make the data more readily accessible while preserving the original paper records, the seismic data from these cruises were scanned and converted to black and white Tagged Image File Format and grayscale Portable Network Graphics images and SEG-Y data files. Navigation data were converted from U.S. Coast Guard Long Range Aids to Navigation time delays to latitudes and longitudes that are available in Environmental Systems Research Institute, Inc., shapefile format and as eastings and northings in space-delimited text format. This report complements two others that contain analog seismic-reflection data from RIS (McMullen and others, 2009) and Long Island and Block Island Sounds (Poppe and others, 2002) and were converted into digital form.
Toward a digital library strategy for a National Information Infrastructure
Coyne, Robert A.; Hulen, Harry
Bills currently before the House and Senate would give support to the development of a National Information Infrastructure, in which digital libraries and storage systems would be an important part. A simple model is offered to show the relationship of storage systems, software, and standards to the overall information infrastructure. Some elements of a national strategy for digital libraries are proposed, based on the mission of the nonprofit National Storage System Foundation.
PG&E's Seismic Network Goes Digital With Strong Motion: Successes and Challenges
Stanton, M. A.; Cullen, J.; McLaren, M. K.
Pacific Gas and Electric Company (PG&E) is in year 3 of a 5-year project to upgrade the Central Coast Seismic Network (CCSN) from analog to digital. Located along the south-central California coast, the CCSN began operation in 1987, with 20 analog stations; 15 vertical component and 5 dual gain 3-component S-13 sensors. The analog signals travel over FM radio telemetry links and voice channels via PG&E's microwave network to our facility in San Francisco (SF), where the A/D conversion is performed on a computer running Earthworm v7.1, which also transmits the data to the USGS in Menlo Park. At the conversion point the dynamic ranges of the vertical and dual-gain sensors are 40-50dB and 60-70dB, respectively. Dynamic range exceedance (data clipping) generally occurs for a M2.5 or greater event within about 40 km of a station. The motivations to upgrade the seismic network were the need for higher dynamic range and to retire obsolete analog transmission equipment. The upgraded digital stations consist of the existing velocity sensors, a 131A-02/3 accelerometer and a Reftek 130-01 Broadband Seismic Recorder for digital data recording and transmission to SF. Vertical only stations have one component of velocity and 3 components of acceleration. Dual gain sites have 3 components of velocity and 3 of acceleration. To date we have successfully upgraded 6 sites; 3 more will be installed by the end of 2008. Some of the advantages of going digital are 1) data is recorded at each site and in SF, 2) substantially increased dynamic range of the velocity sensors to 120dB, as observed by on scale, close-by recordings from a M3.9 San Simeon aftershock on 04/29/2008, 3) accelerometers for on scale recording of large earthquakes, and 4) ability to contribute our strong motion data to USGS ShakeMaps. A significant challenge has been consistent radio communications. To resolve this issue we are installing point-to-multipoint Motorola Canopy spread spectrum radios at the stations and
Preliminary Design Study for a National Digital Seismograph Network
Peterson, Jon; Hutt, Charles R.
Introduction Recently, the National Research Council published a report by the Panel on National, Regional, and Local Seismograph Networks of the Committee on Seismology in which the principal recommendation was for the establishment of a national digital seismograph network (NDSN). The Panel Report (Bolt, 1980) addresses both the need and the scientific requirements for the new national network. The purpose of this study has been to translate the scientific requirements into an instrumentation concept for the NSDS. There are literally hundreds, perhaps thousands, of seismographs in operation within the United States. Each serves an important purpose, but most have limited objectives in time, in region, or in the types of data that are being recorded. The concept of a national network, funded and operated by the Federal Government, is based on broader objectives that include continuity of time, uniform coverage, standardization of data format and instruments, and widespread use of the data for a variety of research purposes. A national digital seismograph network will be an important data resource for many years to come; hence, its design is likely to be of interest to most seismologists. Seismologists have traditionally been involved in the development and field operation of seismic systems and thus have been familiar with both the potential value and the limitations of the data. However, in recent years of increasing technological sophistication, the development of data sstems has fallen more to system engineers, and this trend is likely to continue. One danger in this is that the engineers may misinterpret scientific objectives or subordinate them to purely technological considerations. Another risk is that the data users may misuse or misinterpret the data because they are not aware of the limitations of the data system. Perhaps the most important purpose of a design study such as this is to stimulate a dialogue between system engineers and potential data users

Digital single-channel seismic-reflection data from western Santa Monica basin
Normark, William R.; Piper, David J.W.; Sliter, Ray W.; Triezenberg, Peter; Gutmacher, Christina E.
During a collaborative project in 1992, Geological Survey of Canada and United States Geological Survey scientists obtained about 850 line-km of high-quality single-channel boomer and sleeve-gun seismic-reflection profiles across Hueneme, Mugu and Dume submarine fans, Santa Monica Basin, off southern California. The goals of this work were to better understand the processes that lead to the formation of sandy submarine fans and the role of sea-level changes in controlling fan development. This report includes a trackline map of the area surveyed, as well as images of the sleeve-gun profiles and the opportunity to download both images and digital data files (SEG-Y) of all the sleeve-gun profiles.

Documentation for the 2008 Update of the United States National Seismic Hazard Maps
Petersen, Mark D.; Frankel, Arthur D.; Harmsen, Stephen C.; Mueller, Charles S.; Haller, Kathleen M.; Wheeler, Russell L.; Wesson, Robert L.; Zeng, Yuehua; Boyd, Oliver S.; Perkins, David M.; Luco, Nicolas; Field, Edward H.; Wills, Chris J.; Rukstales, Kenneth S.
The 2008 U.S. Geological Survey (USGS) National Seismic Hazard Maps display earthquake ground motions for various probability levels across the United States and are applied in seismic provisions of building codes, insurance rate structures, risk assessments, and other public policy. This update of the maps incorporates new findings on earthquake ground shaking, faults, seismicity, and geodesy. The resulting maps are derived from seismic hazard curves calculated on a grid of sites across the United States that describe the frequency of exceeding a set of ground motions. The USGS National Seismic Hazard Mapping Project developed these maps by incorporating information on potential earthquakes and associated ground shaking obtained from interaction in science and engineering workshops involving hundreds of participants, review by several science organizations and State surveys, and advice from two expert panels. The National Seismic Hazard Maps represent our assessment of the 'best available science' in earthquake hazards estimation for the United States (maps of Alaska and Hawaii as well as further information on hazard across the United States are available on our Web site at http://earthquake.usgs.gov/research/hazmaps/).
A Digital Library for the National Advisory Committee for Aeronautics
Nelson, Michael L.
We describe the digital library (DL) for the National Advisory Committee for Aeronautics (NACA), the NACA Technical Report Server (NACATRS). The predecessor organization for the National Aeronautics and Space Administration (NASA), NACA existed from 1915 until 1958. The primary manifestation of NACA's research was the NACA report series. We describe the process of converting this collection of reports to digital format and making it available on the World Wide Web (WWW) and is a node in the NASA Technical Report Server (NTRS). We describe the current state of the project, the resulting DL technology developed from the project, and the future plans for NACATRS.
Advanced National Seismic System—Current status, development opportunities, and priorities for 2017–2027
SummaryEarthquakes pose a threat to the safety of over 143 million people living in the United States. Earthquake impacts can be significantly reduced if communities understand their risk and take proactive steps to mitigate that risk. The Advanced National Seismic System (ANSS) is a cooperative effort to collect and analyze seismic and geodetic data on earthquakes, issue timely and reliable notifications of their occurrence and impacts, and provide data for earthquake research and the hazard and risk assessments that are the foundation for creating an earthquakeresilient nation.
A method for producing digital probabilistic seismic landslide hazard maps; an example from the Los Angeles, California, area
Jibson, Randall W.; Harp, Edwin L.; Michael, John A.
The 1994 Northridge, California, earthquake is the first earthquake for which we have all of the data sets needed to conduct a rigorous regional analysis of seismic slope instability. These data sets include (1) a comprehensive inventory of triggered landslides, (2) about 200 strong-motion records of the mainshock, (3) 1:24,000-scale geologic mapping of the region, (4) extensive data on engineering properties of geologic units, and (5) high-resolution digital elevation models of the topography. All of these data sets have been digitized and rasterized at 10-m grid spacing in the ARC/INFO GIS platform. Combining these data sets in a dynamic model based on Newmark's permanent-deformation (sliding-block) analysis yields estimates of coseismic landslide displacement in each grid cell from the Northridge earthquake. The modeled displacements are then compared with the digital inventory of landslides triggered by the Northridge earthquake to construct a probability curve relating predicted displacement to probability of failure. This probability function can be applied to predict and map the spatial variability in failure probability in any ground-shaking conditions of interest. We anticipate that this mapping procedure will be used to construct seismic landslide hazard maps that will assist in emergency preparedness planning and in making rational decisions regarding development and construction in areas susceptible to seismic slope failure.
Valuing national effects of digital health investments: an applied method.
Hagens, Simon; Zelmer, Jennifer; Frazer, Cassandra; Gheorghiu, Bobby; Leaver, Chad
This paper describes an approach which has been applied to value national outcomes of investments by federal, provincial and territorial governments, clinicians and healthcare organizations in digital health. Hypotheses are used to develop a model, which is revised and populated based upon the available evidence. Quantitative national estimates and qualitative findings are produced and validated through structured peer review processes. This methodology has applied in four studies since 2008.
A New Database of Digitized Regional Seismic Waveforms from Nuclear Explosions in Eurasia
Sokolova, I. N.; Richards, P. G.; Kim, W. Y.; Mikhailova, N. N.
Seismology is an observational science. Hence, the effort to understand details of seismic signals from underground nuclear explosions requires analysis of waveforms recorded from past nuclear explosions. Of principal interest, are regional signals from explosions too small to be reliably identified via teleseismic recording. But the great majority of stations operated today, even those in networks for nuclear explosion monitoring, have never recorded explosion signals at regional distances, because most stations were installed long after the period when most underground nuclear explosions were conducted; and the few nuclear explosions since the early 1990s were mostly recorded only at teleseismic distances. We have therefore gathered thousands of nuclear explosion regional seismograms from more than 200 analog stations operated in the former Soviet Union. Most of them lie in a region stretching approximately 6000 km East-West and 2000 km North-South and including much of Central Asia. We have digitized them and created a modern digital database, including significant metadata. Much of this work has been done in Kazakhstan. Most of the explosions were underground, but several were conducted in the atmosphere. This presentation will characterize the content and overall quality of the new database for signals from nuclear explosions in Eurasia, which were conducted across substantial ranges of yield and shot-point depth, and under a great variety of different geological conditions. This work complements a 20-year collaborative effort which made the original digital recordings of the Borovoye Geophysical Observatory, Kazakhstan, openly available in a modern format (see http://www.ldeo.columbia.edu/res/pi/Monitoring/Data/). For purposes of characterizing explosive sources, it would be of assistance to have seismogram archives from explosions conducted in all regions including the Pacific, North Africa, and the United States (including the Aleutians).

The 2014 United States National Seismic Hazard Model
Petersen, Mark D.; Moschetti, Morgan P.; Powers, Peter; Mueller, Charles; Haller, Kathleen; Frankel, Arthur; Zeng, Yuehua; Rezaeian, Sanaz; Harmsen, Stephen; Boyd, Oliver; Field, Edward; Chen, Rui; Rukstales, Kenneth S.; Luco, Nicolas; Wheeler, Russell; Williams, Robert; Olsen, Anna H.
New seismic hazard maps have been developed for the conterminous United States using the latest data, models, and methods available for assessing earthquake hazard. The hazard models incorporate new information on earthquake rupture behavior observed in recent earthquakes; fault studies that use both geologic and geodetic strain rate data; earthquake catalogs through 2012 that include new assessments of locations and magnitudes; earthquake adaptive smoothing models that more fully account for the spatial clustering of earthquakes; and 22 ground motion models, some of which consider more than double the shaking data applied previously. Alternative input models account for larger earthquakes, more complicated ruptures, and more varied ground shaking estimates than assumed in earlier models. The ground motions, for levels applied in building codes, differ from the previous version by less than ±10% over 60% of the country, but can differ by ±50% in localized areas. The models are incorporated in insurance rates, risk assessments, and as input into the U.S. building code provisions for earthquake ground shaking.
The 2014 update to the National Seismic Hazard Model in California
Powers, Peter; Field, Edward H.
The 2014 update to the U. S. Geological Survey National Seismic Hazard Model in California introduces a new earthquake rate model and new ground motion models (GMMs) that give rise to numerous changes to seismic hazard throughout the state. The updated earthquake rate model is the third version of the Uniform California Earthquake Rupture Forecast (UCERF3), wherein the rates of all ruptures are determined via a self-consistent inverse methodology. This approach accommodates multifault ruptures and reduces the overprediction of moderate earthquake rates exhibited by the previous model (UCERF2). UCERF3 introduces new faults, changes to slip or moment rates on existing faults, and adaptively smoothed gridded seismicity source models, all of which contribute to significant changes in hazard. New GMMs increase ground motion near large strike-slip faults and reduce hazard over dip-slip faults. The addition of very large strike-slip ruptures and decreased reverse fault rupture rates in UCERF3 further enhances these effects.

Location Performance and Detection Threshold of the Spanish National Seismic Network
D'Alessandro, Antonino; Badal, José; D'Anna, Giuseppe; Papanastassiou, Dimitris; Baskoutas, Ioannis; Özel, Nurcan M.
Spain is a low-to-moderate seismicity area with relatively low seismic hazard. However, several strong shallow earthquakes have shaken the country causing casualties and extensive damage. Regional seismicity is monitored and surveyed by means of the Spanish National Seismic Network, maintenance and control of which are entrusted to the Instituto Geográfico Nacional. This array currently comprises 120 seismic stations distributed throughout Spanish territory (mainland and islands). Basically, we are interested in checking the noise conditions, reliability, and seismic detection capability of the Spanish network by analyzing the background noise level affecting the array stations, errors in hypocentral location, and detection threshold, which provides knowledge about network performance. It also enables testing of the suitability of the velocity model used in the routine process of earthquake location. To perform this study we use a method that relies on P and S wave travel times, which are computed by simulation of seismic rays from virtual seismic sources placed at the nodes of a regular grid covering the study area. Given the characteristics of the seismicity of Spain, we drew maps for M L magnitudes 2.0, 2.5, and 3.0, at a focal depth of 10 km and a confidence level 95 %. The results relate to the number of stations involved in the hypocentral location process, how these stations are distributed spatially, and the uncertainties of focal data (errors in origin time, longitude, latitude, and depth). To assess the extent to which principal seismogenic areas are well monitored by the network, we estimated the average error in the location of a seismic source from the semiaxes of the ellipsoid of confidence by calculating the radius of the equivalent sphere. Finally, the detection threshold was determined as the magnitude of the smallest seismic event detected at least by four stations. The northwest of the peninsula, the Pyrenees, especially the westernmost segment
Digital information management: a progress report on the National Digital Mammography Archive
Beckerman, Barbara G.; Schnall, Mitchell D.
Digital mammography creates very large images, which require new approaches to storage, retrieval, management, and security. The National Digital Mammography Archive (NDMA) project, funded by the National Library of Medicine (NLM), is developing a limited testbed that demonstrates the feasibility of a national breast imaging archive, with access to prior exams; patient information; computer aids for image processing, teaching, and testing tools; and security components to ensure confidentiality of patient information. There will be significant benefits to patients and clinicians in terms of accessible data with which to make a diagnosis and to researchers performing studies on breast cancer. Mammography was chosen for the project, because standards were already available for digital images, report formats, and structures. New standards have been created for communications protocols between devices, front- end portal and archive. NDMA is a distributed computing concept that provides for sharing and access across corporate entities. Privacy, auditing, and patient consent are all integrated into the system. Five sites, Universities of Pennsylvania, Chicago, North Carolina and Toronto, and BWXT Y12, are connected through high-speed networks to demonstrate functionality. We will review progress, including technical challenges, innovative research and development activities, standards and protocols being implemented, and potential benefits to healthcare systems.
Large-band seismic characterization of the INFN Gran Sasso National Laboratory
Acernese, F.; Canonico, R.; De Rosa, R.; Giordano, G.; Romano, R.; Barone, F.
In this paper we present the scientific data recorded by tunable mechanical monolithic horizontal seismometers located in the Gran Sasso National Laboratory of the INFN, within thermally insulating enclosures onto concrete slabs connected to the bedrock. The main goals of this long-term large-band measurements are for the seismic characterization of the site in the frequency band 10-6÷10Hz and the acquisition of all the relevant information for the optimization of the sensors.
Analysis of recently digitized continuous seismic data recorded during the March-May, 1980, eruption sequence at Mount St. Helens
Moran, S. C.; Malone, S. D.
The May 18, 1980, eruption of Mount St. Helens (MSH) was an historic event, both for society and for the field of volcanology. However, our knowledge of the eruption and the precursory period leading up it is limited by the fact that most of the data, particularly seismic recordings, were not kept due to severe limitations in the amount of digital data that could be handled and stored using 1980 computer technology. Because of these limitations, only about 900 digital event files have been available for seismic studies of the March-May seismic sequence out of a total of more than 4,000 events that were counted using paper records. Fortunately, data from a subset of stations were also recorded continuously on a series of 24 analog 14-track IRIG magnetic tapes. We have recently digitized these tapes and time-corrected and cataloged the resultant digital data streams, enabling more in-depth studies of the (almost) complete pre-eruption seismic sequence using modern digital processing techniques. Of the fifteen seismic stations operating near MSH for at least a part of the two months between March 20 and May 18, six stations have relatively complete analog recordings. These recordings have gaps of minutes to days because of radio noise, poor tape quality, or missing tapes. In addition, several other stations have partial records. All stations had short-period vertical-component sensors with very limited dynamic range and unknown response details. Nevertheless, because the stations were at a range of distances and were operated at a range of gains, a variety of earthquake sizes were recorded on scale by at least one station, and therefore a much more complete understanding of the evolution of event types, sizes and character should be achievable. In our preliminary analysis of this dataset we have found over 10,000 individual events as recorded on stations 35-40 km from MSH, spanning a recalculated coda-duration magnitude range of ~1.5 to 4.1, including many M < 3
A Deep-towed Digital Multichannel Seismic Streamer For Very High-resolution Studies Of Marine Subsurface Structures
Breitzke, M.; Bialas, J.; Inggas Working Group
A deep-towed digital multichannel seismic streamer and side scan sonar system has been developed to collect marine seismic data with a very high lateral in- and cross- line resolution particularly in regions of special interest for gas hydrate research. As marine seismic sources conventional air-, GI or waterguns will be shot close to the sea surface. A depressor of about 2 tons weight ensures the slightly buoyant deep-towed system to keep in depth. The streamer is a modular digital system which can be operated in water depths up to 6000 m. At this stage of development, it consists of a 50 m lead-in cable towed behind the side scan sonar fish and 26 single nodes for each channel. Each node houses a sin- gle hydrophone, low- and high-cut filter, preamplifier and 24-bit AD converter. Three special engineering nodes additionally include a pressure sensor and compass which provide information on the depth of the node and on its geographical position relative to the ship. Nodes are interchangeable and can arbitrarily be connected by cables of 1 or 6.5 m length. A minimum sample interval of 0.25 ms allows to use sufficiently high- frequency seismic sources to guarantee both a very high vertical and lateral resolution. Data are stored both underwater on a linux-based PC with 120 GB storage capacity installed in a pressure vessel mounted on the side scan sonar fish, and onboard on a PC running a data acquisition program and a DLT device. Data are transferred between underwater and onboard systems via telemetry controlled by a second linux-based PC onboard, using coaxial cable or fibre optic technology. The exact position of the side scan sonar fish is determined by the ultra-short base line (USBL) Posidonia system. It mainly consists of a hull-mounted acoustic unit (antenna) and a responder mounted on the side scan sonar fish. Additionally, the three engineering nodes measure the depth and heading of the streamer at three positions relative to the side scan sonar fish. All

These specifications include requirements and standards information about source data requirements, spatial reference system, distribution tiling schemes, horizontal resolution, vertical accuracy, digital elevation model surface treatment, georeferencing, data source and tile dates, distribution and supporting file formats, void areas, metadata, spatial metadata, and quality assurance and control.
UK National Data Centre archive of seismic recordings of (presumed) underground nuclear tests 1964-1996
Young, John; Peacock, Sheila
The year 1996 has particular significance for forensic seismologists. This was the year when the Comprehensive Test Ban Treaty (CTBT) was signed in September at the United Nations, setting an international norm against nuclear testing. Blacknest, as a long time seismic centre for research into detecting and identifying underground explosions using seismology, provided significant technical advice during the CTBT negotiations. Since 1962 seismic recordings of both presumed nuclear explosions and earthquakes from the four seismometer arrays Eskdalemuir, Scotland (EKA), Yellowknife, Canada (YKA), Gauribidanur, India (GBA), and Warramunga, Australia (WRA) have been copied, digitised, and saved. There was a possibility this archive would be lost. It was decided to process the records and catalogue them for distribution to other groups and institutions. This work continues at Blacknest but the archive is no longer under threat. In addition much of the archive of analogue tape recordings has been re-digitised with modern equipment, allowing sampling rates of 100 rather than 20 Hz.
SSHAC Level 1 Probabilistic Seismic Hazard Analysis for the Idaho National Laboratory
Payne, Suzette; Coppersmith, Ryan; Coppersmith, Kevin
A Probabilistic Seismic Hazard Analysis (PSHA) was completed for the Materials and Fuels Complex (MFC), Naval Reactors Facility (NRF), and the Advanced Test Reactor (ATR) at Idaho National Laboratory (INL) (Figure 1-1). The PSHA followed the approaches and procedures appropriate for a Study Level 1 provided in the guidance advanced by the Senior Seismic Hazard Analysis Committee (SSHAC) in U.S. Nuclear Regulatory Commission (NRC) NUREG/CR-6372 and NUREG-2117 (NRC, 1997; 2012a). The SSHAC Level 1 PSHAs for MFC and ATR were conducted as part of the Seismic Risk Assessment (SRA) project (INL Project number 31287) to develop and apply a new-riskmore » informed methodology, respectively. The SSHAC Level 1 PSHA was conducted for NRF to provide guidance on the potential use of a design margin above rock hazard levels. The SRA project is developing a new risk-informed methodology that will provide a systematic approach for evaluating the need for an update of an existing PSHA. The new methodology proposes criteria to be employed at specific analysis, decision, or comparison points in its evaluation process. The first four of seven criteria address changes in inputs and results of the PSHA and are given in U.S. Department of Energy (DOE) Standard, DOE-STD-1020-2012 (DOE, 2012a) and American National Standards Institute/American Nuclear Society (ANSI/ANS) 2.29 (ANS, 2008a). The last three criteria address evaluation of quantitative hazard and risk-focused information of an existing nuclear facility. The seven criteria and decision points are applied to Seismic Design Category (SDC) 3, 4, and 5, which are defined in American Society of Civil Engineers/Structural Engineers Institute (ASCE/SEI) 43-05 (ASCE, 2005). The application of the criteria and decision points could lead to an update or could determine that such update is not necessary.« less

Digitized analog boomer seismic-reflection data collected during U.S. Geological Survey cruises Erda 90-1_HC, Erda 90-1_PBP, and Erda 91-3 in Mississippi Sound, June 1990 and September 1991
Bosse, Stephen T.; Flocks, James G.; Forde, Arnell S.
The U.S. Geological Survey (USGS) Coastal and Marine Geology Program has actively collected geophysical and sedimentological data in the northern Gulf of Mexico for several decades, including shallow subsurface data in the form of high-resolution seismic-reflection profiles (HRSP). Prior to the mid-1990s most HRSP data were collected in analog format as paper rolls of continuous profiles up to 25 meters long. A large portion of this data resides in a single repository with minimal metadata. As part of the National Geological and Geophysical Data Preservation Program, scientists at the USGS St. Petersburg Coastal and Marine Science Center are converting the analog paper records to digital format using a large-format continuous scanner.This report, along with the accompanying USGS data release (Bosse and others, 2017), serves as an archive of seismic profiles with headers, converted Society of Exploration Geophysicists Y format (SEG-Y) files, navigation data, and geographic information system data files for digitized boomer seismic-reflection data collected from the Research Vessel (R/V) Erda during two cruises in 1990 and 1991. The Erda 90-1 geophysical cruise was conducted in two legs. The first leg included seismic data collected from the Hancock County region of the Mississippi Sound (Erda 90-1_HC) from June 4 to June 6, 1990. The second leg included seismic data collected from the Petit Bois Pass area of Mississippi Sound (Erda 90-1_PBP) from June 8 to June 9, 1990.

A Probabilistic Seismic Hazard Analysis (PSHA) was completed for the Materials and Fuels Complex (MFC), Advanced Test Reactor (ATR), and Naval Reactors Facility (NRF) at the Idaho National Laboratory (INL). The PSHA followed the approaches and procedures for Senior Seismic Hazard Analysis Committee (SSHAC) Level 1 study and included a Participatory Peer Review Panel (PPRP) to provide the confident technical basis and mean-centered estimates of the ground motions. A new risk-informed methodology for evaluating the need for an update of an existing PSHA was developed as part of the Seismic Risk Assessment (SRA) project. To develop and implement the newmore » methodology, the SRA project elected to perform two SSHAC Level 1 PSHAs. The first was for the Fuel Manufacturing Facility (FMF), which is classified as a Seismic Design Category (SDC) 3 nuclear facility. The second was for the ATR Complex, which has facilities classified as SDC-4. The new methodology requires defensible estimates of ground motion levels (mean and full distribution of uncertainty) for its criteria and evaluation process. The INL SSHAC Level 1 PSHA demonstrates the use of the PPRP, evaluation and integration through utilization of a small team with multiple roles and responsibilities (four team members and one specialty contractor), and the feasibility of a short duration schedule (10 months). Additionally, a SSHAC Level 1 PSHA was conducted for NRF to provide guidance on the potential use of a design margin above rock hazard levels for the Spent Fuel Handling Recapitalization Project (SFHP) process facility.« less

A fast topographic characterization of seismic station locations in Iran through integrated use of digital elevation models and GIS
Karimzadeh, Sadra; Miyajima, Masakatsu; Kamel, Batoul; Pessina, Vera
We present topographic slope positions of seismic stations within four independent networks (IGUT, IIEES, GSI, and BHRC) in Iran through integrated use of digital elevation models and GIS. Since topographic amplification factor (TAF) due to ground surface irregularity could be one of the reasons of earthquake wave amplification and unexpected damage of structures located on the top of ridges in many previous studies, the ridge stations in the study area are recognized using topographic position index (TPI) as a spatial-based scale-dependent approach that helps in classification of topographic positions. We also present the correlation between local topographic positions and V {/s 30} along with Voronoi tiles of two networks (IGUT and IIEES). The obtained results can be profitably used in seismology to establish homogeneous subnetworks based on Voronoi tiles with precise feedback and in the formulation of new ground motion prediction equations with respect to topographic position and topographic amplification factor.
Digital seismic-reflection data from western Rhode Island Sound, 1980
During 1980, the U.S. Geological Survey (USGS) conducted a seismic-reflection survey in western Rhode Island Sound aboard the Research Vessel Neecho. Data from this survey were recorded in analog form and archived at the USGS Woods Hole Science Center's Data Library. Due to recent interest in the geology of Rhode Island Sound and in an effort to make the data more readily accessible while preserving the original paper records, the seismic data from this cruise were scanned and converted to Tagged Image File Format (TIFF) images and SEG-Y data files. Navigation data were converted from U.S. Coast Guard Long Range Aids to Navigation (LORAN-C) time delays to latitudes and longitudes, which are available in Environmental Systems Research Institute, Inc. (ESRI) shapefile format and as eastings and northings in space-delimited text format.
Site characterization of the Romanian Seismic Network stations: a national initiative and its first preliminary results
Grecu, Bogdan; Zahria, Bogdan; Manea, Elena; Neagoe, Cristian; Borleanu, Felix; Diaconescu, Mihai; Constantinescu, Eduard; Bala, Andrei
The seismic activity in Romania is dominated by the intermediate-depth earthquakes occurring in Vrancea region, although weak to moderate crustal earthquakes are produced regularly in different areas of the country. The National Institute for Earth Physics (NIEP) built in the last years an impressive infrastructure for monitoring this activity, known as the Romanian Seismic Network (RSN). At present, RSN consists of 122 seismic stations, of which 70 have broadband velocity sensors and 42 short period sensors. One hundred and eleven stations out of 122 have accelerometer sensors collocated with velocity sensors and only 10 stations have only accelerometers. All the stations record continuously the ground motion and the data are transmitted in real-time to the Romanian National Data Center (RoNDC), in Magurele. Last year, NIEP has started a national project that addresses the characterization of all real-time seismic stations that constitute the RSN. We present here the steps that were undertaken and the preliminary results obtained since the beginning the project. The first two activities consisted of collecting all the existent technical and geological data, with emphasize on the latter. Then, we performed station noise investigations and analyses in order to characterize the noise level and estimate the resonances of the sites. The computed H/V ratios showed clear resonant peaks at different frequencies which correlate relatively well with the thickness of the sedimentary package beneath the stations. The polarization analysis of the H/V ratios indicates for some stations a strong directivity of the resonance peak which suggests possible topographic effects at the stations. At the same time, special attention was given to the estimation of the site amplification from earthquake data. The spectral ratios obtained from the analysis of more than 50 earthquakes with magnitudes (Mw) larger than 4.1 are characterized by similar resonance peaks as those obtained from
A Comparative Study on Seismic Analysis of Bangladesh National Building Code (BNBC) with Other Building Codes
Bari, Md. S.; Das, T.
Tectonic framework of Bangladesh and adjoining areas indicate that Bangladesh lies well within an active seismic zone. The after effect of earthquake is more severe in an underdeveloped and a densely populated country like ours than any other developed countries. Bangladesh National Building Code (BNBC) was first established in 1993 to provide guidelines for design and construction of new structure subject to earthquake ground motions in order to minimize the risk to life for all structures. A revision of BNBC 1993 is undergoing to make this up to date with other international building codes. This paper aims at the comparison of various provisions of seismic analysis as given in building codes of different countries. This comparison will give an idea regarding where our country stands when it comes to safety against earth quake. Primarily, various seismic parameters in BNBC 2010 (draft) have been studied and compared with that of BNBC 1993. Later, both 1993 and 2010 edition of BNBC codes have been compared graphically with building codes of other countries such as National Building Code of India 2005 (NBC-India 2005), American Society of Civil Engineering 7-05 (ASCE 7-05). The base shear/weight ratios have been plotted against the height of the building. The investigation in this paper reveals that BNBC 1993 has the least base shear among all the codes. Factored Base shear values of BNBC 2010 are found to have increased significantly than that of BNBC 1993 for low rise buildings (≤20 m) around the country than its predecessor. Despite revision of the code, BNBC 2010 (draft) still suggests less base shear values when compared to the Indian and American code. Therefore, this increase in factor of safety against the earthquake imposed by the proposed BNBC 2010 code by suggesting higher values of base shear is appreciable.
Site-specific probabilistic seismic hazard analyses for the Idaho National Engineering Laboratory. Volume 2: Appendices
The identification of seismic sources is often based on a combination of geologic and tectonic considerations and patterns of observed seismicity; hence, a historical earthquake catalogue is important. A historical catalogue of earthquakes of approximate magnitude (M) 2.5 and greater for the time period 1850 through 1992 was compiled for the INEL region. The primary data source used was the Decade of North American Geology (DNAG) catalogue for the time period from about 1800 through 1985 (Engdahl and Rinehart, 1988). A large number of felt earthquakes, especially prior to the 1970`s, which were below the threshold of completeness established inmore » the DNAG catalogue (Engdahl and Rinehart, 1991), were taken from the state catalogues compiled by Stover and colleagues at the National Earthquake Information Center (NEIC) and combined with the DNAG catalogue for the INEL region. The state catalogues were those of Idaho, Montana, Nevada, Utah, and Wyoming. NEIC`s Preliminary Determination of Epicenters (PDE) and the state catalogues compiled by the Oregon Department of Geology and Mineral Industries (DOGAMI), and the University of Nevada at Reno (UNR) were also used to supplement the pre-1986 time period. A few events reanalyzed by Jim Zollweg (Boise State University, written communication, 1994) were also modified in the catalogue. In the case of duplicate events, the DNAG entry was preferred over the Stover et al. entry for the period 1850 through 1985. A few events from Berg and Baker (1963) were also added to the catalogue. This information was and will be used in determining the seismic risk of buildings and facilities located at the Idaho National Engineering Laboratory.« less

Development of a National Digital Geospatial Data Framework
This proposal of a data framework to organize and enhance the activities of the geospatial data community to meet needs for basic themes of data was developed in response to a request in Executive Order 12906, Coordinating Geographic Data Acquisition and Access: The National Spatial Data Infrastructure (U.S. Executive Office of the President, 1994). The request stated: in consultation with State, local, and tribal governments and within 9 months of the date of this order, the FGDC shall submit a plan and schedule to OMB [U.S. Office of Management and Budget] for completing the initial implementation of a national digital geospatial data framework ("framework") by January 2000 and for establishing a process of ongoing data maintenance. The framework shall include geospatial data that are significant, in the determination of the FGDC, to a broad variety of users within any geographic area or nationwide. At a minimum, the plan shall address how the initial transportation, hydrology, and boundary elements of the framework might be completed by January 1998 in order to support the decennial census of 2000. The proposal was developed by representatives of local, regional, State, and Federal agencies under the auspices of the Federal Geographic Data Committee (FGDC). The individuals are listed in the appendix of this report. This Framework Working Group identified the purpose and goals for the framework; identified incentives for participation; defined the information content; developed preliminary technical, operational, and business contexts; specified the institutional roles needed; and developed a strategy for a phased implementation of the framework.Members of the working group presented the concepts of the framework for discussion at several national and regional public meetings. The draft of the report also was provided for public, written review. These discussions and reviews were the source of many improvements to the report.The FGDC approved the report for
Ground motion models used in the 2014 U.S. National Seismic Hazard Maps
Rezaeian, Sanaz; Petersen, Mark D.; Moschetti, Morgan P.
The National Seismic Hazard Maps (NSHMs) are an important component of seismic design regulations in the United States. This paper compares hazard using the new suite of ground motion models (GMMs) relative to hazard using the suite of GMMs applied in the previous version of the maps. The new source characterization models are used for both cases. A previous paper (Rezaeian et al. 2014) discussed the five NGA-West2 GMMs used for shallow crustal earthquakes in the Western United States (WUS), which are also summarized here. Our focus in this paper is on GMMs for earthquakes in stable continental regions in the Central and Eastern United States (CEUS), as well as subduction interface and deep intraslab earthquakes. We consider building code hazard levels for peak ground acceleration (PGA), 0.2-s, and 1.0-s spectral accelerations (SAs) on uniform firm-rock site conditions. The GMM modifications in the updated version of the maps created changes in hazard within 5% to 20% in WUS; decreases within 5% to 20% in CEUS; changes within 5% to 15% for subduction interface earthquakes; and changes involving decreases of up to 50% and increases of up to 30% for deep intraslab earthquakes for most U.S. sites. These modifications were combined with changes resulting from modifications in the source characterization models to obtain the new hazard maps.

The national seismic hazard maps for the conterminous United States have been updated to account for new methods, models, and data that have been obtained since the 2008 maps were released (Petersen and others, 2008). The input models are improved from those implemented in 2008 by using new ground motion models that have incorporated about twice as many earthquake strong ground shaking data and by incorporating many additional scientific studies that indicate broader ranges of earthquake source and ground motion models. These time-independent maps are shown for 2-percent and 10-percent probability of exceedance in 50 years for peak horizontal ground acceleration as well as 5-hertz and 1-hertz spectral accelerations with 5-percent damping on a uniform firm rock site condition (760 meters per second shear wave velocity in the upper 30 m, VS30). In this report, the 2014 updated maps are compared with the 2008 version of the maps and indicate changes of plus or minus 20 percent over wide areas, with larger changes locally, caused by the modifications to the seismic source and ground motion inputs.
Evaluation of potential surface rupture and review of current seismic hazards program at the Los Alamos National Laboratory. Final report
This report summarizes the authors review and evaluation of the existing seismic hazards program at Los Alamos National Laboratory (LANL). The report recommends that the original program be augmented with a probabilistic analysis of seismic hazards involving assignment of weighted probabilities of occurrence to all potential sources. This approach yields a more realistic evaluation of the likelihood of large earthquake occurrence particularly in regions where seismic sources may have recurrent intervals of several thousand years or more. The report reviews the locations and geomorphic expressions of identified fault lines along with the known displacements of these faults and last knowmore » occurrence of seismic activity. Faults are mapped and categorized into by their potential for actual movement. Based on geologic site characterization, recommendations are made for increased seismic monitoring; age-dating studies of faults and geomorphic features; increased use of remote sensing and aerial photography for surface mapping of faults; the development of a landslide susceptibility map; and to develop seismic design standards for all existing and proposed facilities at LANL.« less
Black Thunder Coal Mine and Los Alamos National Laboratory experimental study of seismic energy generated by large scale mine blasting
Martin, R.L.; Gross, D.; Pearson, D.C.
In an attempt to better understand the impact that large mining shots will have on verifying compliance with the international, worldwide, Comprehensive Test Ban Treaty (CTBT, no nuclear explosion tests), a series of seismic and videographic experiments has been conducted during the past two years at the Black Thunder Coal Mine. Personnel from the mine and Los Alamos National Laboratory have cooperated closely to design and perform experiments to produce results with mutual benefit to both organizations. This paper summarizes the activities, highlighting the unique results of each. Topics which were covered in these experiments include: (1) synthesis of seismic,more » videographic, acoustic, and computer modeling data to improve understanding of shot performance and phenomenology; (2) development of computer generated visualizations of observed blasting techniques; (3) documentation of azimuthal variations in radiation of seismic energy from overburden casting shots; (4) identification of, as yet unexplained, out of sequence, simultaneous detonation in some shots using seismic and videographic techniques; (5) comparison of local (0.1 to 15 kilometer range) and regional (100 to 2,000 kilometer range) seismic measurements leading to determine of the relationship between local and regional seismic amplitude to explosive yield for overburden cast, coal bulking and single fired explosions; and (6) determination of the types of mining shots triggering the prototype International Monitoring System for the CTBT.« less
2014 Update of the Pacific Northwest portion of the U.S. National Seismic Hazard Maps
Frankel, Arthur; Chen, Rui; Petersen, Mark; Moschetti, Morgan P.; Sherrod, Brian
Several aspects of the earthquake characterization were changed for the Pacific Northwest portion of the 2014 update of the national seismic hazard maps, reflecting recent scientific findings. New logic trees were developed for the recurrence parameters of M8-9 earthquakes on the Cascadia subduction zone (CSZ) and for the eastern edge of their rupture zones. These logic trees reflect recent findings of additional M8 CSZ earthquakes using offshore deposits of turbidity flows and onshore tsunami deposits and subsidence. These M8 earthquakes each rupture a portion of the CSZ and occur in the time periods between M9 earthquakes that have an average recurrence interval of about 500 years. The maximum magnitude was increased for deep intraslab earthquakes. An areal source zone to account for the possibility of deep earthquakes under western Oregon was expanded. The western portion of the Tacoma fault was added to the hazard maps.
Information system evolution at the French National Network of Seismic Survey (BCSF-RENASS)
Engels, F.; Grunberg, M.
The aging information system of the French National Network of Seismic Survey (BCSF-RENASS), located in Strasbourg (EOST), needed to be updated to satisfy new practices from Computer science world. The latter means to evolve our system at different levels : development method, datamining solutions, system administration. The new system had to provide more agility for incoming projects. The main difficulty was to maintain old system and the new one in parallel the time to validate new solutions with a restricted team. Solutions adopted here are coming from standards used by the seismological community and inspired by the state of the art of devops community. The new system is easier to maintain and take advantage of large community to find support. This poster introduces the new system and choosen solutions like Puppet, Fabric, MongoDB and FDSN Webservices.
The 2018 and 2020 Updates of the U.S. National Seismic Hazard Models
Petersen, M. D.
During 2018 the USGS will update the 2014 National Seismic Hazard Models by incorporating new seismicity models, ground motion models, site factors, fault inputs, and by improving weights to ground motion models using empirical and other data. We will update the earthquake catalog for the U.S. and introduce new rate models. Additional fault data will be used to improve rate estimates on active faults. New ground motion models (GMMs) and site factors for Vs30 have been released by the Pacific Earthquake Engineering Research Center (PEER) and we will consider these in assessing ground motions in craton and extended margin regions of the central and eastern U.S. The USGS will also include basin-depth terms for selected urban areas of the western United States to improve long-period shaking assessments using published depth estimates to 1.0 and 2.5 km/s shear wave velocities. We will produce hazard maps for input into the building codes that span a broad range of periods (0.1 to 5 s) and site classes (shear wave velocity from 2000 m/s to 200 m/s in the upper 30 m of the crust, Vs30). In the 2020 update we plan on including: a new national crustal model that defines basin depths required in the latest GMMs, new 3-D ground motion simulations for several urban areas, new magnitude-area equations, and new fault geodetic and geologic strain rate models. The USGS will also consider including new 3-D ground motion simulations for inclusion in these long-period maps. These new models are being evaluated and will be discussed at one or more regional and topical workshops held at the beginning of 2018.

Zare-Farashbandi, Firoozeh; Najafi, Nayere Sadat Soleimanzade; Atashpour, Bahare
Introduction: The important role of information and communication technologies and their influence on methods of storing, retrieving information in digital libraries, has not only changed the meanings behind classic library activates but has also created great changes in their services. However, it seems that not all digital libraries provide their users with similar services and only some of them are successful in fulfilling their role in digital environment. The Iranian National Medical library is among those that appear to come short compared to other digital libraries around the world. By knowing the different services provided by digital libraries worldwide, one can evaluate the services provided by Iranian National Medical library. The goal of this study is a comparison between Iranian National Medical library and digital libraries of selected countries. Materials and Methods: This is an applied study and uses descriptive – survey method. The statistical population is the digital libraries around the world which were actively providing library services between October and December 2011 and were selected by using the key word “Digital Library� in Google search engine. The data-gathering tool was direct access to the websites of these digital libraries. The statistical study is descriptive and Excel software was used for data analysis and plotting of the charts. Results: The findings showed that among the 33 digital libraries investigated worldwide, most of them provided Browse (87.87%), Search (84.84%), and Electronic information retrieval (57.57%) services. The “Help� in public services (48/48%) and “Interlibrary Loan� in traditional services (27/27%) had the highest frequency. The Iranian National Medical library provides more digital services compared to other libraries but has less classic and public services and has less than half of possible public services. Other than Iranian National Medical library, among the 33 libraries investigated

Time dependent data, time independent models: challenges of updating Australia's National Seismic Hazard Assessment
Griffin, J.; Clark, D.; Allen, T.; Ghasemi, H.; Leonard, M.
Standard probabilistic seismic hazard assessment (PSHA) simulates earthquake occurrence as a time-independent process. However paleoseismic studies in slowly deforming regions such as Australia show compelling evidence that large earthquakes on individual faults cluster within active periods, followed by long periods of quiescence. Therefore the instrumental earthquake catalog, which forms the basis of PSHA earthquake recurrence calculations, may only capture the state of the system over the period of the catalog. Together this means that data informing our PSHA may not be truly time-independent. This poses challenges in developing PSHAs for typical design probabilities (such as 10% in 50 years probability of exceedance): Is the present state observed through the instrumental catalog useful for estimating the next 50 years of earthquake hazard? Can paleo-earthquake data, that shows variations in earthquake frequency over time-scales of 10,000s of years or more, be robustly included in such PSHA models? Can a single PSHA logic tree be useful over a range of different probabilities of exceedance? In developing an updated PSHA for Australia, decadal-scale data based on instrumental earthquake catalogs (i.e. alternative area based source models and smoothed seismicity models) is integrated with paleo-earthquake data through inclusion of a fault source model. Use of time-dependent non-homogeneous Poisson models allows earthquake clustering to be modeled on fault sources with sufficient paleo-earthquake data. This study assesses the performance of alternative models by extracting decade-long segments of the instrumental catalog, developing earthquake probability models based on the remaining catalog, and testing performance against the extracted component of the catalog. Although this provides insights into model performance over the short-term, for longer timescales it is recognised that model choice is subject to considerable epistemic uncertainty. Therefore a formal
Tectonic geomorphology of the New Madrid seismic zone based on imaging of digital topographic data
Mayer, L.
Topographic analysis using digital elevation data of the New Madrid region focuses on topographic features that occur at several spatial scales and can be used to delineate distinct anomalies. In this region, topographic anomalies occur as domal or elongate uplifts and bowl-shaped depressions approximately 1--10 km in size, topographic lineaments, and differences in topographic blocking across 50 km long boundaries. In order to fully explain these topographic anomalies, tectonic processes may be required. Imaging is based on digital topographic data from USGS 30 arc-second, 3 arc-second, and 30 m resolutions. Imaging of these data uses standard imaging processing techniques tomore » examine topography within the contexts of geomorphological hypothesis testing. A good example is the use of thresholding to highlight areas of unusually high elevation given the hypothesis of fluvial landscape architecture. Thresholding delineates topographic features such as the Tiptonville dome which is strongly believed to be tectonic in origin. To determine the pattern of topographic blocking, defined as a pattern that topography assumes when constrained by active forces other than erosion alone, low frequency passing spatial convolutions are used as filters and the resulting data are sliced into blocks according to pseudoelevations that produce a stable block pattern. The resultant blocks are analyzed according to its structural pattern of block size and block orientation. This analysis suggests that a topographic boundary cuts across the Mississippi embayment from near the Newport pluton on the west, to the area south of Memphis on east.« less
California Fault Parameters for the National Seismic Hazard Maps and Working Group on California Earthquake Probabilities 2007
Wills, Chris J.; Weldon, Ray J.; Bryant, W.A.
This report describes development of fault parameters for the 2007 update of the National Seismic Hazard Maps and the Working Group on California Earthquake Probabilities (WGCEP, 2007). These reference parameters are contained within a database intended to be a source of values for use by scientists interested in producing either seismic hazard or deformation models to better understand the current seismic hazards in California. These parameters include descriptions of the geometry and rates of movements of faults throughout the state. These values are intended to provide a starting point for development of more sophisticated deformation models which include known rates of movement on faults as well as geodetic measurements of crustal movement and the rates of movements of the tectonic plates. The values will be used in developing the next generation of the time-independent National Seismic Hazard Maps, and the time-dependant seismic hazard calculations being developed for the WGCEP. Due to the multiple uses of this information, development of these parameters has been coordinated between USGS, CGS and SCEC. SCEC provided the database development and editing tools, in consultation with USGS, Golden. This database has been implemented in Oracle and supports electronic access (e.g., for on-the-fly access). A GUI-based application has also been developed to aid in populating the database.

Lawrence Livermore National Laboratory Site Seismic Safety Program: Summary of Findings
Savy, J B; Foxall, W
The Lawrence Livermore National Laboratory (LLNL) Site Seismic Safety Program was conceived in 1979 during the preparation of the site Draft Environmental Impact Statement. The impetus for the program came from the development of new methodologies and geologic data that affect assessments of geologic hazards at the LLNL site; it was designed to develop a new assessment of the seismic hazard to the LLNL site and LLNL employees. Secondarily, the program was also intended to provide the technical information needed to make ongoing decisions about design criteria for future construction at LLNL and about the adequacy of existing facilities. Thismore » assessment was intended to be of the highest technical quality and to make use of the most recent and accepted hazard assessment methodologies. The basic purposes and objectives of the current revision are similar to those of the previous studies. Although all the data and experience assembled in the previous studies were utilized to their fullest, the large quantity of new information and new methodologies led to the formation of a new team that includes LLNL staff and outside consultants from academia and private consulting firms. A peer-review panel composed of individuals from academia (A. Cornell, Stanford University), the Department of Energy (DOE; Jeff Kimball), and consulting (Kevin Coppersmith), provided review and guidance. This panel was involved from the beginning of the project in a ''participatory'' type of review. The Senior Seismic Hazard Analysis Committee (SSHAC, a committee sponsored by the U.S. Nuclear Regulatory Commission, DOE, and the Electric Power Research Institute) strongly recommends the use of participatory reviews, in which the reviewers follow the progress of a project from the beginning, rather than waiting until the end to provide comments (Budnitz et al., 1997). Following the requirements for probabilistic seismic hazard analysis (PSHA) stipulated in the DOE standard DOE-STD-1023-95, a

Newberry Seismic Deployment Fieldwork Report
Wang, J; Templeton, D C
This report summarizes the seismic deployment of Lawrence Livermore National Laboratory (LLNL) Geotech GS-13 short-period seismometers at the Newberry Enhanced Geothermal System (EGS) Demonstration site located in Central Oregon. This Department of Energy (DOE) demonstration project is managed by AltaRock Energy Inc. AltaRock Energy had previously deployed Geospace GS-11D geophones at the Newberry EGS Demonstration site, however the quality of the seismic data was somewhat low. The purpose of the LLNL deployment was to install more sensitive sensors which would record higher quality seismic data for use in future seismic studies, such as ambient noise correlation, matched field processing earthquakemore » detection studies, and general EGS microearthquake studies. For the LLNL deployment, seven three-component seismic stations were installed around the proposed AltaRock Energy stimulation well. The LLNL seismic sensors were connected to AltaRock Energy Gueralp CMG-DM24 digitizers, which are powered by AltaRock Energy solar panels and batteries. The deployment took four days in two phases. In phase I, the sites were identified, a cavity approximately 3 feet deep was dug and a flat concrete pad oriented to true North was made for each site. In phase II, we installed three single component GS-13 seismometers at each site, quality controlled the data to ensure that each station was recording data properly, and filled in each cavity with native soil.« less

Computation of dynamic seismic responses to viscous fluid of digitized three-dimensional Berea sandstones with a coupled finite-difference method.
Zhang, Yang; Toksöz, M Nafi
The seismic response of saturated porous rocks is studied numerically using microtomographic images of three-dimensional digitized Berea sandstones. A stress-strain calculation is employed to compute the velocities and attenuations of rock samples whose sizes are much smaller than the seismic wavelength of interest. To compensate for the contributions of small cracks lost in the imaging process to the total velocity and attenuation, a hybrid method is developed to recover the crack distribution, in which the differential effective medium theory, the Kuster-Toksöz model, and a modified squirt-flow model are utilized in a two-step Monte Carlo inversion. In the inversion, the velocities of P- and S-waves measured for the dry and water-saturated cases, and the measured attenuation of P-waves for different fluids are used. By using such a hybrid method, both the velocities of saturated porous rocks and the attenuations are predicted accurately when compared to laboratory data. The hybrid method is a practical way to model numerically the seismic properties of saturated porous rocks until very high resolution digital data are available. Cracks lost in the imaging process are critical for accurately predicting velocities and attenuations of saturated porous rocks.

Patton, John M.; Guy, Michelle R.; Benz, Harley M.; Buland, Raymond P.; Erickson, Brian K.; Kragness, David S.
This report provides an overview of the capabilities and design of Hydra, the global seismic monitoring and analysis system used for earthquake response and catalog production at the U.S. Geological Survey National Earthquake Information Center (NEIC). Hydra supports the NEIC’s worldwide earthquake monitoring mission in areas such as seismic event detection, seismic data insertion and storage, seismic data processing and analysis, and seismic data output.The Hydra system automatically identifies seismic phase arrival times and detects the occurrence of earthquakes in near-real time. The system integrates and inserts parametric and waveform seismic data into discrete events in a database for analysis. Hydra computes seismic event parameters, including locations, multiple magnitudes, moment tensors, and depth estimates. Hydra supports the NEIC’s 24/7 analyst staff with a suite of seismic analysis graphical user interfaces.In addition to the NEIC’s monitoring needs, the system supports the processing of aftershock and temporary deployment data, and supports the NEIC’s quality assurance procedures. The Hydra system continues to be developed to expand its seismic analysis and monitoring capabilities.

Tsunami hazard maps of spanish coast at national scale from seismic sources
Aniel-Quiroga, Ã�ñigo; González, Mauricio; Ã�lvarez-Gómez, José Antonio; GarcÃa, Pablo
Tsunamis are a moderately frequent phenomenon in the NEAM (North East Atlantic and Mediterranean) region, and consequently in Spain, as historic and recent events have affected this area. I.e., the 1755 earthquake and tsunami affected the Spanish Atlantic coasts of Huelva and Cadiz and the 2003 Boumerdés earthquake triggered a tsunami that reached Balearic island coast in less than 45 minutes. The risk in Spain is real and, its population and tourism rate makes it vulnerable to this kind of catastrophic events. The Indian Ocean tsunami in 2004 and the tsunami in Japan in 2011 launched the worldwide development and application of tsunami risk reduction measures that have been taken as a priority in this field. On November 20th 2015 the directive of the Spanish civil protection agency on planning under the emergency of tsunami was presented. As part of the Spanish National Security strategy, this document specifies the structure of the action plans at different levels: National, regional and local. In this sense, the first step is the proper evaluation of the tsunami hazard at National scale. This work deals with the assessment of the tsunami hazard in Spain, by means of numerical simulations, focused on the elaboration of tsunami hazard maps at National scale. To get this, following a deterministic approach, the seismic structures whose earthquakes could generate the worst tsunamis affecting the coast of Spain have been compiled and characterized. These worst sources have been propagated numerically along a reconstructed bathymetry, built from the best resolution available data. This high-resolution bathymetry was joined with a 25-m resolution DTM, to generate continuous offshore-onshore space, allowing the calculation of the flooded areas prompted by each selected source. The numerical model applied for the calculation of the tsunami propagations was COMCOT. The maps resulting from the numerical simulations show not only the tsunami amplitude at coastal areas but
High-resolution gravity and seismic-refraction surveys of the Smoke Tree Wash area, Joshua Tree National Park, California
Langenheim, Victoria E.; Rymer, Michael J.; Catchings, Rufus D.; Goldman, Mark R.; Watt, Janet T.; Powell, Robert E.; Matti, Jonathan C.
We describe high-resolution gravity and seismic refraction surveys acquired to determine the thickness of valley-fill deposits and to delineate geologic structures that might influence groundwater flow beneath the Smoke Tree Wash area in Joshua Tree National Park. These surveys identified a sedimentary basin that is fault-controlled. A profile across the Smoke Tree Wash fault zone reveals low gravity values and seismic velocities that coincide with a mapped strand of the Smoke Tree Wash fault. Modeling of the gravity data reveals a basin about 2–2.5 km long and 1 km wide that is roughly centered on this mapped strand, and bounded by inferred faults. According to the gravity model the deepest part of the basin is about 270 m, but this area coincides with low velocities that are not characteristic of typical basement complex rocks. Most likely, the density contrast assumed in the inversion is too high or the uncharacteristically low velocities represent highly fractured or weathered basement rocks, or both. A longer seismic profile extending onto basement outcrops would help differentiate which scenario is more accurate. The seismic velocities also determine the depth to water table along the profile to be about 40–60 m, consistent with water levels measured in water wells near the northern end of the profile.

Implementation of NGA-West2 ground motion models in the 2014 U.S. National Seismic Hazard Maps
Rezaeian, Sanaz; Petersen, Mark D.; Moschetti, Morgan P.; Powers, Peter; Harmsen, Stephen C.; Frankel, Arthur D.
The U.S. National Seismic Hazard Maps (NSHMs) have been an important component of seismic design regulations in the United States for the past several decades. These maps present earthquake ground shaking intensities at specified probabilities of being exceeded over a 50-year time period. The previous version of the NSHMs was developed in 2008; during 2012 and 2013, scientists at the U.S. Geological Survey have been updating the maps based on their assessment of the “best available science,� resulting in the 2014 NSHMs. The update includes modifications to the seismic source models and the ground motion models (GMMs) for sites across the conterminous United States. This paper focuses on updates in the Western United States (WUS) due to the use of new GMMs for shallow crustal earthquakes in active tectonic regions developed by the Next Generation Attenuation (NGA-West2) project. Individual GMMs, their weighted combination, and their impact on the hazard maps relative to 2008 are discussed. In general, the combined effects of lower medians and increased standard deviations in the new GMMs have caused only small changes, within 5–20%, in the probabilistic ground motions for most sites across the WUS compared to the 2008 NSHMs.

Contribution of seismic processing to put up the scaffolding for the 3-dimensional study of deep sedimentary basins: the fundaments of trans-national 3D modelling in the project GeoMol
Capar, Laure
Within the framework of the transnational project GeoMol geophysical and geological information on the entire Molasse Basin and on the Po Basin are gathered to build consistent cross-border 3D geological models based on borehole evidence and seismic data. Benefiting from important progress in seismic processing, these new models will provide some answers to various questions regarding the usage of subsurface resources, as there are geothermal energy, CO2 and gas storage, oil and gas production, and support decisions-making to national and local administrations as well as to industries. More than 28 000 km of 2D seismic lines are compiled reprocessed and harmonized. This work faces various problems like the vertical drop of more than 700 meters between West and East of the Molasse Basin and to al lesser extent in the Po Plain, the heterogeneities of the substratum, the large disparities between the period and parameters of seismic acquisition, and depending of their availability, the use of two types of seismic data, raw and processed seismic data. The main challenge is to harmonize all lines at the same reference level, amplitude and step of signal processing from France to Austria, spanning more than 1000 km, to avoid misfits at crossing points between seismic lines and artifacts at the country borders, facilitating the interpretation of the various geological layers in the Molasse Basin and Po Basin. A generalized stratigraphic column for the two basins is set up, representing all geological layers relevant to subsurface usage. This stratigraphy constitutes the harmonized framework for seismic reprocessing. In general, processed seismic data is available on paper at stack stage and the mandatory information to take these seismic lines to the final stage of processing, the migration step, are datum plane and replacement velocity. However several datum planes and replacement velocities were used during previous processing projects. Our processing sequence is to

Minimally invasive surgery for pedal digital deformity: an audit of complications using national benchmark indicators.
Gilheany, Mark; Baarini, Omar; Samaras, Dean
There is increasing global interest and performance of minimally invasive foot surgery (MIS) however, limited evidence is available in relation to complications associated with MIS for digital deformity correction. The aim of this prospective audit is to report the surgical and medical complications following MIS for digital deformity against standardised clinical indicators. A prospective clinical audit of 179 patients who underwent MIS to reduce simple and complex digital deformities was conducted between June 2011 and June 2013. All patients were followed up to a minimum of 12Â months post operatively. Data was collected according to a modified version of the Australian Council of Healthcare standards (ACHS) clinical indicator program. The audit was conducted in accordance with the National Research Ethics Service (NRES) guidelines on clinical audit. The surgical complications included 1 superficial infection (0.53%) and 2 under-corrected digits (0.67%), which required revision surgery. Two patients who underwent isolated complex digital corrections had pain due to delayed union (0.7%), which resolved by 6Â months post-op. No neurovascular compromise and no medical complications were encountered. The results compare favourably to rates reported in the literature for open reduction of digital deformity. This audit has illustrated that performing MIS to address simple and complex digital deformity results in low complication rates compared to published standards. MIS procedures were safely performed in a range of clinical settings, on varying degrees of digital deformity and on a wide range of ages and health profiles. Further studies investigating the effectiveness of these techniques are warranted and should evaluate long term patient reported outcome measures, as well as developing treatment algorithms to guide clinical decision making.
Digital Data Acquisition System for experiments with segmented detectors at National Superconducting Cyclotron Laboratory
Starosta, K.; Vaman, C.; Miller, D.; Voss, P.; Bazin, D.; Glasmacher, T.; Crawford, H.; Mantica, P.; Tan, H.; Hennig, W.; Walby, M.; Fallu-Labruyere, A.; Harris, J.; Breus, D.; Grudberg, P.; Warburton, W. K.
A 624-channel Digital Data Acquisition System capable of instrumenting the Segmented Germanium Array at National Superconducting Cyclotron Laboratory has been implemented using Pixie-16 Digital Gamma Finder modules by XIA LLC. The system opens an opportunity for determination of the first interaction position of a γ ray in a SeGA detector from implementation of γ-ray tracking. This will translate into a significantly improved determination of angle of emission, and in consequence much better Doppler corrections for experiments with fast beams. For stopped-beam experiments the system provides means for zero dead time measurements of rare decays, which occur on time scales of microseconds.

The boomer plate is an acoustic energy source that consists of capacitors charged to a high voltage and discharged through a transducer in the water. The transducer is towed on a sled floating on the water surface and when discharged emits a short acoustic pulse, or shot, which propagates through the water, sediment column, or rock beneath. The acoustic energy is reflected at density boundaries (such as the seafloor, sediment, or rock layers beneath the
Earthquake Monitoring: SeisComp3 at the Swiss National Seismic Network
Clinton, J. F.; Diehl, T.; Cauzzi, C.; Kaestli, P.
The Swiss Seismological Service (SED) has an ongoing responsibility to improve the seismicity monitoring capability for Switzerland. This is a crucial issue for a country with low background seismicity but where a large M6+ earthquake is expected in the next decades. With over 30 stations with spacing of ~25km, the SED operates one of the densest broadband networks in the world, which is complimented by ~ 50 realtime strong motion stations. The strong motion network is expected to grow with an additional ~80 stations over the next few years. Furthermore, the backbone of the network is complemented by broadband data from surrounding countries and temporary sub-networks for local monitoring of microseismicity (e.g. at geothermal sites). The variety of seismic monitoring responsibilities as well as the anticipated densifications of our network demands highly flexible processing software. We are transitioning all software to the SeisComP3 (SC3) framework. SC3 is a fully featured automated real-time earthquake monitoring software developed by GeoForschungZentrum Potsdam in collaboration with commercial partner, gempa GmbH. It is in its core open source, and becoming a community standard software for earthquake detection and waveform processing for regional and global networks across the globe. SC3 was originally developed for regional and global rapid monitoring of potentially tsunamagenic earthquakes. In order to fulfill the requirements of a local network recording moderate seismicity, SED has tuned configurations and added several modules. In this contribution, we present our SC3 implementation strategy, focusing on the detection and identification of seismicity on different scales. We operate several parallel processing "pipelines" to detect and locate local, regional and global seismicity. Additional pipelines with lower detection thresholds can be defined to monitor seismicity within dense subnets of the network. To be consistent with existing processing
National Archive of Marine Seismic Surveys (NAMSS): A USGS-Boem Partnership to Provide Free and Easy Access to Previously Proprietary Seismic Reflection Data on the U.S. Outer Continental Shelf
Triezenberg, P. J.; Hart, P. E.; Childs, J. R.
The National Archive of Marine Seismic Surveys (NAMSS) was established by the USGS in 2004 in an effort to rescue marine seismic reflection profile data acquired largely by the oil exploration industry throughout the US outer continental shelf (OCS). It features a Web interface for easy on-line geographic search and download. The commercial value of these data had decreased significantly because of drilling moratoria and newer acquisition technology, and large quantities were at risk of disposal. But, the data still had tremendous value for scientific research and education purposes, and an effort was undertaken to ensure that the data were preserved and publicly available. More recently, the USGS and Bureau of Ocean Energy Management (BOEM) have developed a partnership to make similarly available a much larger quantity of 2D and 3D seismic data acquired by the U.S. government for assessment of resources in the OCS. Under Federal regulation, BOEM is required to publicly release all processed geophysical data, including seismic profiles, acquired under an exploration permit, purchased and retained by BOEM, no sooner than 25 years after issuance of the permit. Data acquired prior to 1989 are now eligible for release. Currently these data are distributed on CD or DVD, but data discovery can be tedious. Inclusion of these data within NAMSS vastly increases the amount of seismic data available for research purposes. A new NAMSS geographical interface provides easy and intuitive access to the data library. The interface utilizes OpenLayers, Mapnik, and the Django web framework. In addition, metadata capabilities have been greatly increased using a PostgresSQL/PostGIS database incorporating a community-developed ISO-compliant XML template. The NAMSS database currently contains 452 2D seismic surveys comprising 1,645,956 line km and nine 3D seismic surveys covering 9,385 square km. The 2D data holdings consist of stack, migrated and depth sections, most in SEG-Y format.
Seismicity of Afghanistan and vicinity
Dewey, James W.
This publication describes the seismicity of Afghanistan and vicinity and is intended for use in seismic hazard studies of that nation. Included are digital files with information on earthquakes that have been recorded in Afghanistan and vicinity through mid-December 2004. Chapter A provides an overview of the seismicity and tectonics of Afghanistan and defines the earthquake parameters included in the 'Summary Catalog' and the 'Summary of Macroseismic Effects.' Chapter B summarizes compilation of the 'Master Catalog' and 'Sub-Threshold Catalog' and documents their formats. The 'Summary Catalog' itself is presented as a comma-delimited ASCII file, the 'Summary of Macroseismic Effects' is presented as an html file, and the 'Master Catalog' and 'Sub-Threshold Catalog' are presented as flat ASCII files. Finally, this report includes as separate plates a digital image of a map of epicenters of earthquakes occurring since 1964 (Plate 1) and a representation of areas of damage or strong shaking from selected past earthquakes in Afghanistan and vicinity (Plate 2).
Digital Management and Curation of the National Rock and Ore Collections at NMNH, Smithsonian
Cottrell, E.; Andrews, B.; Sorensen, S. S.; Hale, L. J.
The National Museum of Natural History, Smithsonian Institution, is home to the world's largest curated rock collection. The collection houses 160,680 physical rock and ore specimen lots ("samples"), all of which already have a digital record that can be accessed by the public through a searchable web interface (http://collections.mnh.si.edu/search/ms/). In addition, there are 66 accessions pending that when catalogued will add approximately 60,000 specimen lots. NMNH's collections are digitally managed on the KE EMu° platform which has emerged as the premier system for managing collections in natural history museums worldwide. In 2010 the Smithsonian released an ambitious 5 year Digitization Strategic Plan. In Mineral Sciences, new digitization efforts in the next five years will focus on integrating various digital resources for volcanic specimens. EMu sample records will link to the corresponding records for physical eruption information housed within the database of Smithsonian's Global Volcanism Program (GVP). Linkages are also planned between our digital records and geochemical databases (like EarthChem or PetDB) maintained by third parties. We anticipate that these linkages will increase the use of NMNH collections as well as engender new scholarly directions for research. Another large project the museum is currently undertaking involves the integration of the functionality of in-house designed Transaction Management software with the EMu database. This will allow access to the details (borrower, quantity, date, and purpose) of all loans of a given specimen through its catalogue record. We hope this will enable cross-referencing and fertilization of research ideas while avoiding duplicate efforts. While these digitization efforts are critical, we propose that the greatest challenge to sample curation is not posed by digitization and that a global sample registry alone will not ensure that samples are available for reuse. We suggest instead that the ability
Using Seismic Refraction and Ground Penetrating Radar (GPR) to Characterize the Valley Fill in Beaver Meadows, Rocky Mountain National Park
Kramer, N.; Harry, D. L.; Wohl, E. E.
This study is one of the first to use near surface geophysical techniques to characterize the subsurface stratigraphy in a high alpine, low gradient valley with a past glacial history and to obtain a preliminary grasp on the impact of Holocene beaver activity. Approximately 1 km of seismic refraction data and 5 km of GPR data were collected in Beaver Meadows, Rocky Mountain National Park. An asymmetric wedge of sediment ranging in depth from 0-20 m transverse to the valley profile was identified using seismic refraction. Complementary analysis of the GPR data suggests that the valley fill can be subdivided into till deposited during the Pleistocene glaciations and alluvium deposited during the Holocene. Two main facies were identified in the GPR profiles through pattern recognition. Facie Fd, which consists of chaotic discontinuous reflectors with an abundance of diffractions, is interpreted to be glacial till. Facie Fc, which is a combination of packages of complex slightly continuous reflectors interfingered with continuous horizontal to subhorizontal reflectors, is interpreted to be post-glacial alluvium and includes overbank, pond and in-channel deposits. Fc consistently overlies Fd throughout the study area and is no more than 7 m thick in the middle of the valley. The thickness of Holocene sedimentation (<7 m) is much less than the total amount of valley fill identified in the seismic refraction survey (0-20 m). A subfacie of Fc, Fch, which has reflectors with long periods was identified within Fc and is interpreted to be ponded sediments. The spatial distribution of facie Fch, along with: slight topographical features resembling buried beaver dams, a high abundance of fine sediment including silts and clays, historical records of beavers, and the name "Beaver Meadows" all suggest that Holocene beaver activity played a large role in sediment accumulation at this site, despite the lack of surficial relict beaver dams containing wood.
Seismic Symphonies
Strinna, Elisa; Ferrari, Graziano
symbolize cosmic harmony. But here it is the earth, "nature", the ground beneath our feet that is moving. It speaks to us not of harmony, but of our fragility. For the oldest earthquakes considered, Seismic Symphonies drew on SISMOS archives, the INGV project for recovery, high resolution digital reproduction and distribution of the seismograms of earthquakes of the Euro-Mediterranean area from 1895 to 1984. After the first exposure to the Fondazione Bevilacqua La Masa in Venice, the organ was later exhibited in Taiwan, the Taipei Biennial, with seismograms provided from the Taiwanese Central Weather Bureau, and at the EACC Castello in Spain, with seismograms of Spanish earthquakes provided by the Instituto Geográfico Nacional.

Building a National Heritage Registry for the Sudan: the Friedrich W. Hinkel Archive Digitization Project
Lawrenz, S.
The Republic of the Sudan is home to outstanding and diverse cultural heritage ranging from Neolithic sites of human activity and settlement to historic sites of the 19th and 20th century. While certain phases of the Sudan's cultural heritage such as the period of Egyptian influence during the second and first millennium B.C. have been the focus of archaeological research since the 19th century, other aspects of the country's rich history have remained largely unknown locally and internationally due to a lack of documentation and registration of such sites. Since 2014, the German Archaeological Institute (DAI) has been engaged in an effort to support the creation of a national heritage registry in close cooperation with the National Corporation for Antiquities and Museums (NCAM) by digitizing the archive of German architect Friedrich W. Hinkel and engaging in capacity building measures focusing on analog and digital data curation. The archive contains structured information (photos, drawings, maps and assembled written documentation) regarding over 14,000 archaeological and historical sites in the Sudan using an alphanumeric coding system that allows for easy integration of data in a digital environment such as the DAI's IT infrastructure, the iDAI.world. As such the data assembled by Hinkel will serve as the basis of the national heritage registry currently in development.
Seismic-reflection investigations of the Texas Springs Syncline for ground water development, Death Valley National Park
Machette, Michael N.; Stephenson, W.J.; Williams, R.A.; Odum, J.K.; Worley, D.M.; Dart, R.L.
The U.S. Geological Survey has completed an integrated geologic and geophysical study of the Texas Springs syncline for the National Park Service with the intention of locating a new production water well near existing water-collection and distribution facilities. Subsurface information was required to determine which, if any, sites within the syncline would be favorable for a well. About 4.2 km (2.6 mi.) of high-resolution seismic-reflection data were collected across and along the Texas Springs syncline. Two of our three lines, designated DV-1 and DV-3, cross the syncline, whereas the third line (DV-2) runs parallel to the north-northwest-trending syncline axis.

Seismic databases of The Caucasus
Gunia, I.; Sokhadze, G.; Mikava, D.; Tvaradze, N.; Godoladze, T.
The Caucasus is one of the active segments of the Alpine-Himalayan collision belt. The region needs continues seismic monitoring systems for better understanding of tectonic processes going in the region. Seismic Monitoring Center of Georgia (Ilia State University) is operating the digital seismic network of the country and is also collecting and exchanging data with neighboring countries. The main focus of our study was to create seismic database which is well organized, easily reachable and is convenient for scientists to use. The seismological database includes the information about more than 100 000 earthquakes from the whole Caucasus. We have to mention that it includes data from analog and digital seismic networks. The first analog seismic station in Georgia was installed in 1899 in the Caucasus in Tbilisi city. The number of analog seismic stations was increasing during next decades and in 1980s about 100 analog stations were operated all over the region. From 1992 due to political and economical situation the number of stations has been decreased and in 2002 just two analog equipments was operated. New digital seismic network was developed in Georgia since 2003. The number of digital seismic stations was increasing and in current days there are more than 25 digital stations operating in the country. The database includes the detailed information about all equipments installed on seismic stations. Database is available online. That will make convenient interface for seismic data exchange data between Caucasus neighboring countries. It also makes easier both the seismic data processing and transferring them to the database and decreases the operator's mistakes during the routine work. The database was created using the followings: php, MySql, Javascript, Ajax, GMT, Gmap, Hypoinverse.
Seismicity and fluid geochemistry at Lassen Volcanic National Park, California: Evidence for two circulation cells in the hydrothermal system
Janik, Cathy J.; McLaren, Marcia K.
Seismic analysis and geochemical interpretations provide evidence that two separate hydrothermal cells circulate within the greater Lassen hydrothermal system. One cell originates south to SW of Lassen Peak and within the Brokeoff Volcano depression where it forms a reservoir of hot fluid (235-270 °C) that boils to feed steam to the high-temperature fumarolic areas, and has a plume of degassed reservoir liquid that flows southward to emerge at Growler and Morgan Hot Springs. The second cell originates SSE to SE of Lassen Peak and flows southeastward along inferred faults of the Walker Lane belt (WLB) where it forms a reservoir of hot fluid (220-240 °C) that boils beneath Devils Kitchen and Boiling Springs Lake, and has an outflow plume of degassed liquid that boils again beneath Terminal Geyser. Three distinct seismogenic zones (identified as the West, Middle, and East seismic clusters) occur at shallow depths (< 6 km) in Lassen Volcanic National Park, SW to SSE of Lassen Peak and adjacent to areas of high-temperature (≤ 161 °C) fumarolic activity (Sulphur Works, Pilot Pinnacle, Little Hot Springs Valley, and Bumpass Hell) and an area of cold, weak gas emissions (Cold Boiling Lake). The three zones are located within the inferred Rockland caldera in response to interactions between deeply circulating meteoric water and hot brittle rock that overlies residual magma associated with the Lassen Volcanic Center. Earthquake focal mechanisms and stress inversions indicate primarily N-S oriented normal faulting and E-W extension, with some oblique faulting and right lateral shear in the East cluster. The different focal mechanisms as well as spatial and temporal earthquake patterns for the East cluster indicate a greater influence by regional tectonics and inferred faults within the WLB. A fourth, deeper (5-10 km) seismogenic zone (the Devils Kitchen seismic cluster) occurs SE of the East cluster and trends NNW from Sifford Mountain toward the Devils Kitchen thermal

Digitally-Assisted Stone Carving of a Relief Sculpture for the Parliament Buildings National Historic Site of Canada
Hayes, J.; Fai, S.; Kretz, S.; Ouimet, C.; White, P.
The emerging field of digital fabrication is a process where three-dimensional datasets can be directly transferred to fabrication equipment to create models or even 1:1 building elements. In this paper, we will discuss the results of a collaboration between the Carleton Immersive Media Studio (CIMS), the Dominion Sculptor of Canada, and the Heritage Conservation Directorate (HCD) of Public Works and Government Services Canada (PWGSC), that utilizes digital fabrication technologies in the development of a digitally-assisted stone carving process. The collaboration couples the distinguished skill of the Dominion Sculptor with the latest digital acquisition and digital fabrication technologies for the reconstruction of a deteriorated stone bas-relief on the façade of the East Block building of the Parliament Buildings National Historic Site of Canada. The intention of the research is to establish a workflow of hybrid digital/analogue methodologies from acquisition through rehabilitation and ultimately to the fabrication of stone elements.
Digital analytical data from mineral resource assessments of national forest lands in Washington
Boleneus, D.E.; Chase, D.W.
Extensive reconnaissance assessments of the mineral resource potential of the Colville and Okanogan National Forests in northeastern Washington were conducted during 1979-1982 by a private consultant A.R. Grant, under contract with the U.S. Department of Agriculture, Forest Service. These forests occupy large parts of Pend Oreille, Stevens, Ferry, and Okanogan counties, and smaller parts of Whatcom, Skagit, and Chelan counties adjoining Okanogan County in the Cascades. Sampled terrain also included the Kaniksu National Forest in Pend Oreille County and one stream bed of the Kaniksu in adjacent Bonner County, Idaho. Two unpublished reports resulting from the assessments (Grant, 1982a,b) list a total of 3,927 analyses of gold, silver, copper, lead, zinc, molybdenum, tungsten, and uranium content of stream sediment and bedrock samples collected at widely dispersed sites in the three National Forests. This report makes this important body of work available in digital form on diskettes, to enhance manipulations with computer spreadsheets, geographic information systems (GIS), and digital spatial analyses. This will allow for utilization of data by modern day explorationists and by the general geodata user community.
50 years of Global Seismic Observations
Anderson, K. R.; Butler, R.; Berger, J.; Davis, P.; Derr, J.; Gee, L.; Hutt, C. R.; Leith, W. S.; Park, J. J.
Seismological recordings have been made on Earth for hundreds of years in some form or another, however, global monitoring of earthquakes only began in the 1890's when John Milne created 40 seismic observatories to measure the waves from these events. Shortly after the International Geophysical Year (IGY), a concerted effort was made to establish and maintain a more modern standardized seismic network on the global scale. In the early 1960's, the World-Wide Standardized Seismograph Network (WWSSN) was established through funding from the Advanced Research Projects Agency (ARPA) and was installed and maintained by the USGS's Albuquerque Seismological Laboratory (then a part of the US Coast and Geodetic Survey). This network of identical seismic instruments consisted of 120 stations in 60 countries. Although the network was motivated by nuclear test monitoring, the WWSSN facilitated numerous advances in observational seismology. From the IGY to the present, the network has been upgraded (High-Gain Long-Period Seismograph Network, Seismic Research Observatories, Digital WWSSN, Global Telemetered Seismograph Network, etc.) and expanded (International Deployment of Accelerometers, US National Seismic Network, China Digital Seismograph Network, Joint Seismic Project, etc.), bringing the modern day Global Seismographic Network (GSN) to a current state of approximately 150 stations. The GSN consists of state-of-the-art very broadband seismic transducers, continuous power and communications, and ancillary sensors including geodetic, geomagnetic, microbarographic, meteorological and other related instrumentation. Beyond the GSN, the system of global network observatories includes contributions from other international partners (e.g., GEOSCOPE, GEOFON, MEDNET, F-Net, CTBTO), forming an even larger backbone of permanent seismological observatories as a part of the International Federation of Digital Seismograph Networks. 50 years of seismic network operations have provided
Implementing Audio Digital Feedback Loop Using the National Instruments RIO System
Huang, G.; Byrd, J. M.
Development of system for high precision RF distribution and laser synchronization at Berkeley Lab has been ongoing for several years. Successful operation of these systems requires multiple audio bandwidth feedback loops running at relatively high gains. Stable operation of the feedback loops requires careful design of the feedback transfer function. To allow for flexible and compact implementation, we have developed digital feedback loops on the National Instruments Reconfigurable Input/Output (RIO) platform. This platform uses an FPGA and multiple I/Os that can provide eight parallel channels running different filters. We present the design and preliminary experimental results of this system.
Readiness for Delivering Digital Health at Scale: Lessons From a Longitudinal Qualitative Evaluation of a National Digital Health Innovation Program in the United Kingdom

Background Digital health has the potential to support care delivery for chronic illness. Despite positive evidence from localized implementations, new technologies have proven slow to become accepted, integrated, and routinized at scale. Objective The aim of our study was to examine barriers and facilitators to implementation of digital health at scale through the evaluation of a £37m national digital health program: ‟Delivering Assisted Living Lifestyles at Scale� (dallas) from 2012-2015. Methods The study was a longitudinal qualitative, multi-stakeholder, implementation study. The methods included interviews (n=125) with key implementers, focus groups with consumers and patients (n=7), project meetings (n=12), field work or observation in the communities (n=16), health professional survey responses (n=48), and cross program documentary evidence on implementation (n=215). We used a sociological theory called normalization process theory (NPT) and a longitudinal (3 years) qualitative framework analysis approach. This work did not study a single intervention or population. Instead, we evaluated the processes (of designing and delivering digital health), and our outcomes were the identified barriers and facilitators to delivering and mainstreaming services and products within the mixed sector digital health ecosystem. Results We identified three main levels of issues influencing readiness for digital health: macro (market, infrastructure, policy), meso (organizational), and micro (professional or public). Factors hindering implementation included: lack of information technology (IT) infrastructure, uncertainty around information governance, lack of incentives to prioritize interoperability, lack of precedence on accountability within the commercial sector, and a market perceived as difficult to navigate. Factors enabling implementation were: clinical endorsement, champions who promoted digital health, and public and professional willingness. Conclusions

Issues in testing the new national seismic hazard model for Italy
Stein, S.; Peresan, A.; Kossobokov, V. G.; Brooks, E. M.; Spencer, B. D.
It is important to bear in mind that we know little about how earthquake hazard maps actually describe the shaking that will actually occur in the future, and have no agreed way of assessing how well a map performed in the past, and, thus, whether one map performs better than another. Moreover, we should not forget that different maps can be useful for different end users, who may have different cost-and-benefit strategies. Thus, regardless of the specific tests we chose to use, the adopted testing approach should have several key features: We should assess map performance using all the available instrumental, paleo seismology, and historical intensity data. Instrumental data alone span a period much too short to capture the largest earthquakes - and thus strongest shaking - expected from most faults. We should investigate what causes systematic misfit, if any, between the longest record we have - historical intensity data available for the Italian territory from 217 B.C. to 2002 A.D. - and a given hazard map. We should compare how seismic hazard maps developed over time. How do the most recent maps for Italy compare to earlier ones? It is important to understand local divergences that show how the models are developing to the most recent one. The temporal succession of maps is important: we have to learn from previous errors. We should use the many different tests that have been proposed. All are worth trying, because different metrics of performance show different aspects of how a hazard map performs and can be used. We should compare other maps to the ones we are testing. Maps can be made using a wide variety of assumptions, which will lead to different predicted shaking. It is possible that maps derived by other approaches may perform better. Although Italian current codes are based on probabilistic maps, it is important from both a scientific and societal perspective to look at all options including deterministic scenario based ones.

Reprocessing Seismic Data - Using Wits Seismic Exploration Data to Image the Karoo Basin

During the heyday of seismic exploration of the Witwatersrand Basin, Anglo American's Gold Division acquired several thousand kilometres of Vibroseis reflection seismic data. These data, acquired from 1983-1994, were collected with the goal of finding extensions to the Witwatersrand Basin. In a prescient move, over 500 line kilometres were collected at 16 s two way travel time (TWT), extending to depths of 50 -70 km and have provided critical insight into the formation of the Kaapvaal Craton. In addition to these deep seismic lines, Anglo American acquired an extensive network of heretofore unpublished seismic lines that were collected at 6 sec TWT extending well beyond the known limits of the Witwatersrand Basin. The South African government as part of the national geophysical program in the late 1980s acquired six research reflection seismic lines in varied geological settings accruing another 700 km of data. Many of these data are now hosted at the University of the Witwatersrand's newly established Seismic Research Centre and represent unprecedented coverage and research opportunities. With recent global interest in shale gas, attention focused on the Karoo Basin in South Africa. Early exploration seismic data acquired by Soekor in the 1970s has been lost; however, digitized paper records indicate clear reflection targets. Here we examine one of the AngloGold seismic lines that was acquired in the middle of the Karoo Basin just south of Trompsburg extending to the southeast towards Molteno. This 150 km long line crosses the edge of the Kaapvaal Craton and shows clear reflectors throughout the Karoo Basin. These include the well-defined base of the Karoo and a number of dolerite sills within it. Nearby gas escape structures have been identified on surface and it is likely that several disruptions along this line are related to these or to dykes associated with the sills.

Angola Seismicity MAP
Neto, F. A. P.; Franca, G.
The purpose of this job was to study and document the Angola natural seismicity, establishment of the first database seismic data to facilitate consultation and search for information on seismic activity in the country. The study was conducted based on query reports produced by National Institute of Meteorology and Geophysics (INAMET) 1968 to 2014 with emphasis to the work presented by Moreira (1968), that defined six seismogenic zones from macro seismic data, with highlighting is Zone of Sá da Bandeira (Lubango)-Chibemba-Oncócua-Iona. This is the most important of Angola seismic zone, covering the epicentral Quihita and Iona regions, geologically characterized by transcontinental structure tectono-magmatic activation of the Mesozoic with the installation of a wide variety of intrusive rocks of ultrabasic-alkaline composition, basic and alkaline, kimberlites and carbonatites, strongly marked by intense tectonism, presenting with several faults and fractures (locally called corredor de Lucapa). The earthquake of May 9, 1948 reached intensity VI on the Mercalli-Sieberg scale (MCS) in the locality of Quihita, and seismic active of Iona January 15, 1964, the main shock hit the grade VI-VII. Although not having significant seismicity rate can not be neglected, the other five zone are: Cassongue-Ganda-Massano de Amorim; Lola-Quilengues-Caluquembe; Gago Coutinho-zone; Cuima-Cachingues-Cambândua; The Upper Zambezi zone. We also analyzed technical reports on the seismicity of the middle Kwanza produced by Hidroproekt (GAMEK) region as well as international seismic bulletins of the International Seismological Centre (ISC), United States Geological Survey (USGS), and these data served for instrumental location of the epicenters. All compiled information made possible the creation of the First datbase of seismic data for Angola, preparing the map of seismicity with the reconfirmation of the main seismic zones defined by Moreira (1968) and the identification of a new seismic
Geodesy- and geology-based slip-rate models for the Western United States (excluding California) national seismic hazard maps
Petersen, Mark D.; Zeng, Yuehua; Haller, Kathleen M.; McCaffrey, Robert; Hammond, William C.; Bird, Peter; Moschetti, Morgan; Shen, Zhengkang; Bormann, Jayne; Thatcher, Wayne
The 2014 National Seismic Hazard Maps for the conterminous United States incorporate additional uncertainty in fault slip-rate parameter that controls the earthquake-activity rates than was applied in previous versions of the hazard maps. This additional uncertainty is accounted for by new geodesy- and geology-based slip-rate models for the Western United States. Models that were considered include an updated geologic model based on expert opinion and four combined inversion models informed by both geologic and geodetic input. The two block models considered indicate significantly higher slip rates than the expert opinion and the two fault-based combined inversion models. For the hazard maps, we apply 20 percent weight with equal weighting for the two fault-based models. Off-fault geodetic-based models were not considered in this version of the maps. Resulting changes to the hazard maps are generally less than 0.05 g (acceleration of gravity). Future research will improve the maps and interpret differences between the new models.
The Digital Divide and Health Disparities in China: Evidence From a National Survey and Policy Implications.
Hong, Y Alicia; Zhou, Zi; Fang, Ya; Shi, Leiyu
The digital divide persists despite broad accessibility of mobile tools. The relationship between the digital divide and health disparities reflects social status in terms of access to resources and health outcomes; however, data on this relationship are limited from developing countries such as China. The aim of this study was to examine the current rates of access to mobile tools (Internet use and mobile phone ownership) among older Chinese individuals (aged ≥45 years), the predictors of access at individual and community levels, and the relationship between access to mobile tools and health outcomes. We drew cross-sectional data from a national representative survey, the China Health and Retirement Longitudinal Study (CHARLS), which focused on the older population (aged ≥45 years). We used two-level mixed logistic regression models, controlling for unobserved heterogeneity at the community and individual levels for data analysis. In addition to individual-level socioeconomic status (SES), we included community-level resources such as neighborhood amenities, health care facilities, and community organizations. Health outcomes were measured by self-reported health and absence of disability based on validated scales. Among the 18,215 participants, 6.51% had used the Internet in the past month, and 83% owned a mobile phone. In the multivariate models, Internet use was strongly associated with SES, rural or urban residence, neighborhood amenities, community resources, and geographic region. Mobile phone ownership was strongly associated with SES and rural/urban residence but not so much with neighborhood amenities and community resources. Internet use was a significant predictor of self-reported health status, and mobile phone ownership was significantly associated with having disability even after controlling for potential confounders at the individual and community levels. This study is one of the first to examine digital divide and its relationship with health

Out of a digital chrysalis: NIHNMF (pronounced nymph--the National Indigenous Health and New Media Forum).
Cattoni, Jan; Gamble, Lucinda; Gibson, Julie; Hunter, Ernest; Jones, Anita; Mitchell, Sarah; Pelham, Steven; Smith, Rakana; Travers, Helen
In conjunction with the Creating Futures conference, the inaugural meeting of the National Indigenous Health and New Media Forum (NIHNMF--pronounced as 'nymph') was held at the Tanks Gallery in Cairns, Queensland, Australia. This paper describes the background to this innovative meeting of media minds. It also explores an emerging vision for addressing Indigenous health disparities through digital inclusion to overcome the 'digital divide' between mainstream and Indigenous Australians that constrains the delivery of appropriate health promotion to this health priority population.
Digital Mapping and Environmental Characterization of National Wild and Scenic River Systems
McManamay, Ryan A; Bosnall, Peter; Hetrick, Shelaine L
Spatially accurate geospatial information is required to support decision-making regarding sustainable future hydropower development. Under a memorandum of understanding among several federal agencies, a pilot study was conducted to map a subset of National Wild and Scenic Rivers (WSRs) at a higher resolution and provide a consistent methodology for mapping WSRs across the United States and across agency jurisdictions. A subset of rivers (segments falling under the jurisdiction of the National Park Service) were mapped at a high resolution using the National Hydrography Dataset (NHD). The spatial extent and representation of river segments mapped at NHD scale were compared withmore » the prevailing geospatial coverage mapped at a coarser scale. Accurately digitized river segments were linked to environmental attribution datasets housed within the Oak Ridge National Laboratory s National Hydropower Asset Assessment Program database to characterize the environmental context of WSR segments. The results suggest that both the spatial scale of hydrography datasets and the adherence to written policy descriptions are critical to accurately mapping WSRs. The environmental characterization provided information to deduce generalized trends in either the uniqueness or the commonness of environmental variables associated with WSRs. Although WSRs occur in a wide range of human-modified landscapes, environmental data layers suggest that they provide habitats important to terrestrial and aquatic organisms and recreation important to humans. Ultimately, the research findings herein suggest that there is a need for accurate, consistent, mapping of the National WSRs across the agencies responsible for administering each river. Geospatial applications examining potential landscape and energy development require accurate sources of information, such as data layers that portray realistic spatial representations.« less
Key science issues in the central and eastern United States for the next version of the USGS National Seismic Hazard Maps
Peterson, M.D.; Mueller, C.S.
The USGS National Seismic Hazard Maps are updated about every six years by incorporating newly vetted science on earthquakes and ground motions. The 2008 hazard maps for the central and eastern United States region (CEUS) were updated by using revised New Madrid and Charleston source models, an updated seismicity catalog and an estimate of magnitude uncertainties, a distribution of maximum magnitudes, and several new ground-motion prediction equations. The new models resulted in significant ground-motion changes at 5 Hz and 1 Hz spectral acceleration with 5% damping compared to the 2002 version of the hazard maps. The 2008 maps have now been incorporated into the 2009 NEHRP Recommended Provisions, the 2010 ASCE-7 Standard, and the 2012 International Building Code. The USGS is now planning the next update of the seismic hazard maps, which will be provided to the code committees in December 2013. Science issues that will be considered for introduction into the CEUS maps include: 1) updated recurrence models for New Madrid sources, including new geodetic models and magnitude estimates; 2) new earthquake sources and techniques considered in the 2010 model developed by the nuclear industry; 3) new NGA-East ground-motion models (currently under development); and 4) updated earthquake catalogs. We will hold a regional workshop in late 2011 or early 2012 to discuss these and other issues that will affect the seismic hazard evaluation in the CEUS.
Vegetation mapping of Nowitna National Wildlife Reguge, Alaska using Landsat MSS digital data
Talbot, S. S.; Markon, Carl J.
A Landsat-derived vegetation map was prepared for Nowitna National Wildlife Refuge. The refuge lies within the middle boreal subzone of north central Alaska. Seven major vegetation classes and sixteen subclasses were recognized: forest (closed needleleaf, open needleleaf, needleleaf woodland, mixed, and broadleaf); broadleaf scrub (lowland, alluvial, subalpine); dwarf scrub (prostrate dwarf shrub tundra, dwarf shrub-graminoid tussock peatland); herbaceous (graminoid bog, marsh and meadow); scarcely vegetated areas (scarcely vegetated scree and floodplain); water (clear, turbid); and other areas (mountain shadow). The methodology employed a cluster-block technique. Sample areas were described based on a combination of helicopter-ground survey, aerial photointerpretation, and digital Landsat data. Major steps in the Landsat analysis involved preprocessing (geometric correction), derivation of statistical parameters for spectral classes, spectral class labeling of sample areas, preliminary classification of the entire study area using a maximum-likelihood algorithm, and final classification utilizing ancillary information such as digital elevation data. The final product is a 1:250,000-scale vegetation map representative of distinctive regional patterns and suitable for use in comprehensive conservation planning.

Talbot, Stephen S.; Markon, Carl J.
A Landsat-derived vegetation map was prepared for lnnoko National Wildlife Refuge. The refuge lies within the northern boreal subzone of northwestern central Alaska. Six major vegetation classes and 21 subclasses were recognized: forest (closed needleleaf, open needleleaf, needleleaf woodland, mixed, and broadleaf); broadleaf scrub (lowland, upland burn regeneration, subalpine); dwarf scrub (prostrate dwarf shrub tundra, erect dwarf shrub heath, dwarf shrub-graminoid peatland, dwarf shrub-graminoid tussock peatland, dwarf shrub raised bog with scattered trees, dwarf shrub-graminoid marsh); herbaceous (graminoid bog, graminoid marsh, graminoid tussock-dwarf shrub peatland); scarcely vegetated areas (scarcely vegetated scree and floodplain); and water (clear, sedimented). The methodology employed a cluster-block technique. Sample areas were described based on a combination of helicopter-ground survey, aerial photo-interpretation, and digital Landsat data. Major steps in the Landsat analysis involved preprocessing (geometric correction), derivation of statistical parameters for spectral classes, spectral class labeling of sample areas, preliminary classification of the entire study area using a maximum-likelihood algorithm, and final classification utilizing ancillary information such as digital elevation data.

Seismic Velocities and Thicknesses of Alluvial Deposits along Baker Creek in the Great Basin National Park, East-Central Nevada
Allander, Kip K.; Berger, David L.
To better understand how proposed large-scale water withdrawals in Snake Valley may affect the water resources and hydrologic processes in the Great Basin National Park, the National Park Service needs to have a better understanding of the relations between streamflow and groundwater flow through alluvium and karst topography of the Pole Canyon Limestone. Information that is critical to understanding these relations is the thickness of alluvial deposits that overlay the Pole Canyon Limestone. In mid-April 2009, the U.S. Geological Survey and National Park Service used seismic refraction along three profiles adjacent to Baker Creek to further refine understanding of the local geology. Two refractors and three distinct velocity layers were detected along two of the profiles and a single refractor and two distinct velocity layers were detected along a third profile. In the unsaturated alluvium, average velocity was 2,000 feet per second, thickness ranged from about 7 to 20 feet along two profiles downstream of the Narrows, and thickness was at least 100 feet along a single profile upstream of the Narrows. Saturated alluvium was only present downstream of the Narrows - average velocity was 4,400 feet per second, and thickness ranged from about 40 to 110 feet. The third layer probably represented Pole Canyon Limestone or Tertiary granitic rock units with an average velocity of 12,500 feet per second. Along the upstream and middle profiles (profiles 3 and 1, respectively), the depth to top of the third layer ranged from at least 60 to 110 feet below land surface and is most likely the Pole Canyon Limestone. The third layer at the farthest downstream profile (profile 2) may be a Tertiary granitic rock unit. Baker Creek is disconnected from the groundwater system along the upstream profile (profile 3) and streamflow losses infiltrate vertically downward to the Pole Canyon Limestone. Along the downstream and middle profiles (profiles 2 and 1, respectively), the presence of
A Near Real-Time Seismic Exploration and Monitoring (i.e., Ambient Seismic Noise Interferometry) Solution Based Upon a Novel "At the Edge" Approach that Leverages Commercially Available Digitizers, Embedded Systems, and an Open-Source Big Data Architecture
Sepulveda, F.; Thangraj, J. S.; Quiros, D.; Pulliam, J.; Queen, J. H.; Queen, M.; Iovenitti, J. L.
Seismic interferometry that makes use of ambient noise requires that cross-correlations of data recorded at two or more stations be stacked over a "long enough" time interval that off-axis sources cancel and the estimated inter-station Green's function converges to the actual function. However, the optimal length of the recording period depends on the characteristics of ambient noise at the site, which vary over time and are therefore not known before data acquisition. Data acquisition parameters cannot be planned in ways that will ensure success while minimizing cost and effort. Experiment durations are typically either too long or too short. Automated, in-field processing can provide inter-station Green's functions in near-real-time, allowing for the immediate evaluation of results and enabling operators to alter data acquisition parameters before demobilizing. We report on the design, system integration, and testing of a strategy for the automation of data acquisition, distribution, and processing of ambient noise using industry-standard, widely-available instrumentation (Reftek 130-01 digitizers and 4.5 Hz geophones). Our solution utilizes an inexpensive embedded system (Raspberry Pi 3), which is configured to acquire data from the Reftek and insert it into a big data store called Apache Cassandra. Cassandra distributes and maintains up-to-date copies of the data, through a WiFi network, as defined by tunable consistency levels and replication factors thus allowing for efficient multi-station computations. At regular intervals, data is extracted from Cassandra and is used to compute Green's functions for all receiver pairs. Results are reviewed and progress toward convergence can be assessed. We successfully tested a 20-node prototype of what we call the "Raspberry Pi-Enhanced Reftek" (RaPiER) array at the Soda Lake Geothermal Field in Nevada in June 2017. While intermittent problems with the WiFi network interfered with the real-time data delivery from some
Shallow 3-D vertical seismic profiling around a contaminant withdrawal well on the Lawrence Livermore National Laboratory Site
Rector, J.; Bainer, R.; Milligan, P.
One of the major problems associated with ground water contaminant remediation is well placement. Optimal-placement of wells requires an accurate knowledge of geologic structure and stratigraphy in the near surface sediments and rock (0 to 100 m). Without the development of remote imaging provided by geophysical techniques, the required spacing between treatment wells may be less than 2 m in order to be confident that all contaminant reservoirs had been remediated. One method for characterizing geologic structure and stratigraphy in the near surface is vertical seismic profiling (VSP), a technique often used on deep exploration wells to calibrate surface seismicmore » reflection data. For near-surface applications, VSP data can be acquired efficiently using an array of hydrophones lowered into a fluid-filled borehole (Milligan et al, 1997). In this paper we discuss the acquisition and processing of a 3-D VSP collected at a shallow remediation site located on the grounds of the Lawrence Livermore National Laboratory (LLNL) near Livermore, California. The site was used by the United States Navy as an air training base. At this time, initial releases of hazardous materials to the environment occurred in the form of solvents [volatile organic compounds (VOCs)] that were used for the cleaning of airplanes and their parts. Gasoline, diesel and other petroleum-based compounds are also known to have leaked into the ground. California Research and Development Company, a subsidy of Standard Oil, occupied the southeastern portion of the site from 1950 to 1954. The first releases of radioactive materials to the environment occurred at this time, with the beginning of testing of radioactive materials at the site. In 1952, LLNL acquired the site. Additional releases of VOCS, polychlorinated biphenyls (PCBs), metals, radionuclides (primarily tritium), gasoline and pesticides have occurred since. These releases were due to localized spills, landfills, surface impoundments
The performance of the stations of the Romanian seismic network in monitoring the local seismic activity
Ardeleanu, Luminita Angela; Neagoe, Cristian
The seismic survey of the territory of Romania is mainly performed by the national seismic network operated by the National Institute for Earth Physics of Bucharest. After successive developments and upgrades, the network consists at present of 123 permanent stations equipped with high quality digital instruments (Kinemetrics K2, Quantera Q330, Quantera Q330HR, PS6-24 and Basalt digitizers) - 102 real time and 20 off-line stations - which cover the whole territory of the country. All permanent stations are supplied with 3 component accelerometers (episenzor type), while the real time stations are in addition provided with broadband (CMG3ESP, CMG40T, KS2000, KS54000, KS2000, CMG3T, STS2) or short period (SH-1, S13, Mark l4c, Ranger, GS21, L22_VEL) velocity sensors. Several communication systems are currently used for the real time data transmission: an analog line in UHF band, a line through GPRS (General Packet Radio Service), a dedicated line through satellite, and a dedicated line provided by the Romanian Special Telecommunication Service. During the period January 1, 2006 - June 30, 2013, 5936 shallow depth seismic events - earthquakes and quarry blasts - with local magnitude ML ≥ 1.2 were localized on the Romanian territory, or in its immediate vicinity, using the records of the national seismic network; 1467 subcrustal earthquakes (depth ≥ 60 km) with magnitude ML ≥ 1.9 were also localized in the Vrancea region, at the bend of the Eastern Carpathians. The goal of the present study is to evaluate the individual contribution of the real time seismic stations to the monitoring of the local seismicity. The performance of each station is estimated by taking into consideration the fraction of events that are localised using the station records, compared to the total number of events of the catalogue, occurred during the time of station operation. Taking into account the nonuniform space distribution of earthquakes, the location of the site and the recovery

Lehman, Constance D; Arao, Robert F; Sprague, Brian L; Lee, Janie M; Buist, Diana S M; Kerlikowske, Karla; Henderson, Louise M; Onega, Tracy; Tosteson, Anna N A; Rauscher, Garth H; Miglioretti, Diana L
Purpose To establish performance benchmarks for modern screening digital mammography and assess performance trends over time in U.S. community practice. Materials and Methods This HIPAA-compliant, institutional review board-approved study measured the performance of digital screening mammography interpreted by 359 radiologists across 95 facilities in six Breast Cancer Surveillance Consortium (BCSC) registries. The study included 1 682 504 digital screening mammograms performed between 2007 and 2013 in 792 808 women. Performance measures were calculated according to the American College of Radiology Breast Imaging Reporting and Data System, 5th edition, and were compared with published benchmarks by the BCSC, the National Mammography Database, and performance recommendations by expert opinion. Benchmarks were derived from the distribution of performance metrics across radiologists and were presented as 50th (median), 10th, 25th, 75th, and 90th percentiles, with graphic presentations using smoothed curves. Results Mean screening performance measures were as follows: abnormal interpretation rate (AIR), 11.6 (95% confidence interval [CI]: 11.5, 11.6); cancers detected per 1000 screens, or cancer detection rate (CDR), 5.1 (95% CI: 5.0, 5.2); sensitivity, 86.9% (95% CI: 86.3%, 87.6%); specificity, 88.9% (95% CI: 88.8%, 88.9%); false-negative rate per 1000 screens, 0.8 (95% CI: 0.7, 0.8); positive predictive value (PPV) 1, 4.4% (95% CI: 4.3%, 4.5%); PPV2, 25.6% (95% CI: 25.1%, 26.1%); PPV3, 28.6% (95% CI: 28.0%, 29.3%); cancers stage 0 or 1, 76.9%; minimal cancers, 57.7%; and node-negative invasive cancers, 79.4%. Recommended CDRs were achieved by 92.1% of radiologists in community practice, and 97.1% achieved recommended ranges for sensitivity. Only 59.0% of radiologists achieved recommended AIRs, and only 63.0% achieved recommended levels of specificity. Conclusion The majority of radiologists in the BCSC surpass cancer detection recommendations for screening
National Performance Benchmarks for Modern Diagnostic Digital Mammography: Update from the Breast Cancer Surveillance Consortium.
Sprague, Brian L; Arao, Robert F; Miglioretti, Diana L; Henderson, Louise M; Buist, Diana S M; Onega, Tracy; Rauscher, Garth H; Lee, Janie M; Tosteson, Anna N A; Kerlikowske, Karla; Lehman, Constance D
Purpose To establish contemporary performance benchmarks for diagnostic digital mammography with use of recent data from the Breast Cancer Surveillance Consortium (BCSC). Materials and Methods Institutional review board approval was obtained for active or passive consenting processes or to obtain a waiver of consent to enroll participants, link data, and perform analyses. Data were obtained from six BCSC registries (418 radiologists, 92 radiology facilities). Mammogram indication and assessments were prospectively collected for women undergoing diagnostic digital mammography and linked with cancer diagnoses from state cancer registries. The study included 401 548 examinations conducted from 2007 to 2013 in 265 360 women. Results Overall diagnostic performance measures were as follows: cancer detection rate, 34.7 per 1000 (95% confidence interval [CI]: 34.1, 35.2); abnormal interpretation rate, 12.6% (95% CI: 12.5%, 12.7%); positive predictive value (PPV) of a biopsy recommendation (PPV 2 ), 27.5% (95% CI: 27.1%, 27.9%); PPV of biopsies performed (PPV 3 ), 30.4% (95% CI: 29.9%, 30.9%); false-negative rate, 4.8 per 1000 (95% CI: 4.6, 5.0); sensitivity, 87.8% (95% CI: 87.3%, 88.4%); and specificity, 90.5% (95% CI: 90.4%, 90.6%). Among cancers detected, 63.4% were stage 0 or 1 cancers, 45.6% were minimal cancers, the mean size of invasive cancers was 21.2 mm, and 69.6% of invasive cancers were node negative. Performance metrics varied widely across diagnostic indications, with cancer detection rate (64.5 per 1000) and abnormal interpretation rate (18.7%) highest for diagnostic mammograms obtained to evaluate a breast problem with a lump. Compared with performance during the screen-film mammography era, diagnostic digital performance showed increased abnormal interpretation and cancer detection rates and decreasing PPVs, with less than 70% of radiologists within acceptable ranges for PPV 2 and PPV 3 . Conclusion These performance measures can serve as national
Seismic Catalogue and Seismic Network in Haiti
Belizaire, D.; Benito, B.; Carreño, E.; Meneses, C.; Huerfano, V.; Polanco, E.; McCormack, D.
The destructive earthquake occurred on January 10, 2010 in Haiti, highlighted the lack of preparedness of the country to address seismic phenomena. At the moment of the earthquake, there was no seismic network operating in the country, and only a partial control of the past seismicity was possible, due to the absence of a national catalogue. After the 2010 earthquake, some advances began towards the installation of a national network and the elaboration of a seismic catalogue providing the necessary input for seismic Hazard Studies. This paper presents the state of the works carried out covering both aspects. First, a seismic catalogue has been built, compiling data of historical and instrumental events occurred in the Hispaniola Island and surroundings, in the frame of the SISMO-HAITI project, supported by the Technical University of Madrid (UPM) and Developed in cooperation with the Observatoire National de l'Environnement et de la Vulnérabilité of Haiti (ONEV). Data from different agencies all over the world were gathered, being relevant the role of the Dominican Republic and Puerto Rico seismological services which provides local data of their national networks. Almost 30000 events recorded in the area from 1551 till 2011 were compiled in a first catalogue, among them 7700 events with Mw ranges between 4.0 and 8.3. Since different magnitude scale were given by the different agencies (Ms, mb, MD, ML), this first catalogue was affected by important heterogeneity in the size parameter. Then it was homogenized to moment magnitude Mw using the empirical equations developed by Bonzoni et al (2011) for the eastern Caribbean. At present, this is the most exhaustive catalogue of the country, although it is difficult to assess its degree of completeness. Regarding the seismic network, 3 stations were installed just after the 2010 earthquake by the Canadian Government. The data were sent by telemetry thought the Canadian System CARINA. In 2012, the Spanish IGN together

Digital pathology access and usage in the UK: results from a national survey on behalf of the National Cancer Research Institute's CM-Path initiative.
Williams, Bethany Jill; Lee, Jessica; Oien, Karin A; Treanor, Darren
To canvass the UK pathology community to ascertain current levels of digital pathology usage in clinical and academic histopathology departments, and prevalent attitudes to digital pathology. A 15-item survey was circulated to National Health Service and academic pathology departments across the UK using the SurveyMonkey online survey tool. Responses were sought at a departmental or institutional level. Where possible, departmental heads were approached and asked to complete the survey, or forward it to the most relevant individual in their department. Data were collected over a 6-month period from February to July 2017. 41 institutes from across the UK responded to the survey. 60% (23/39) of institutions had access to a digital pathology scanner, and 60% (24/40) had access to a digital pathology workstation. The most popular applications of digital pathology in current use were undergraduate and postgraduate teaching, research and quality assurance. Investigating the deployment of digital pathology in their department was identified as a high or highest priority by 58.5% of institutions, with improvements in efficiency, turnaround times, reporting times and collaboration in their institution anticipated by the respondents. Access to funding for initial hardware, software and staff outlay, pathologist training and guidance from the Royal College of Pathologists were identified as factors that could enable respondent institutions to increase their digital pathology usage. Interest in digital pathology adoption in the UK is high, with usage likely to increase in the coming years. In light of this, pathologists are seeking more guidance on safe usage. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

Methods A 15-item survey was circulated to National Health Service and academic pathology departments across the UK using the SurveyMonkey online survey tool. Responses were sought at a departmental or institutional level. Where possible, departmental heads were approached and asked to complete the survey, or forward it to the most relevant individual in their department. Data were collected over a 6-month period from February to July 2017. Results 41 institutes from across the UK responded to the survey. 60% (23/39) of institutions had access to a digital pathology scanner, and 60% (24/40) had access to a digital pathology workstation. The most popular applications of digital pathology in current use were undergraduate and postgraduate teaching, research and quality assurance. Investigating the deployment of digital pathology in their department was identified as a high or highest priority by 58.5% of institutions, with improvements in efficiency, turnaround times, reporting times and collaboration in their institution anticipated by the respondents. Access to funding for initial hardware, software and staff outlay, pathologist training and guidance from the Royal College of Pathologists were identified as factors that could enable respondent institutions to increase their digital pathology usage. Conclusion Interest in digital pathology adoption in the UK is high, with usage likely to increase in the coming years. In light of this, pathologists are seeking more guidance on safe usage.

Change Detection via Cross-Borehole and VSP Seismic Surveys for the Source Physics Experiments (SPE) at the Nevada National Security Site (NNSS)
Knox, H. A.; Abbott, R. E.; Bonal, N. D.; Aldridge, D. F.; Preston, L. A.; Ober, C.
In support of the Source Physics Experiment (SPE) at the Nevada National Security Site (NNSS), we have conducted two cross-borehole seismic experiments in the Climax Stock. The first experiment was conducted prior to the third shot in this multi-detonation program using two available boreholes and the shot hole, while the second experiment was conducted after the shot using four of the available boreholes. The first study focused on developing a well-characterized 2D pre-explosion Vp model including two VSPs and a seismic refraction survey, as well as quantifying baseline waveform similarity at reoccupied sites. This was accomplished by recording both "sparker" and accelerated weight drop sources on a hydrophone string and surface geophones. In total more than 18,500 unique source-receiver pairs were acquired during this testing. In the second experiment, we reacquired aproximately 8,800 source-receiver pairs and performed a cross-line survey allowing for a 3D post-explosion Vp model. The data acquired from the reoccupied sites was processed using cross-correlation methods and change detection methodologies, including comparison of the tomographic images. The survey design and subsequent processing provided an opportunity to investigate seismic wave propagation through damaged rock. We also performed full waveform forward modelling for a granitic body hosting a perched aquifer.

Impact of 3-D seismic data on the Nigerian National Petroleum Corporation/Chevron Nigeria Limited joint venture development drilling program
Quam, S.
The Nigerian National Petroleum Corporation/Chevron Nigeria Limited joint venture has been acquiring three-dimensional (3-D) seismic data over its concessions since 1984. To date, 1700 km[sup 2] have been recorded and processed at a cumulative cost of US $39 million. During 1991 - 1992, 20 development wells were drilled based directly on new 3-D seismic interpretations. These wells have added 148 million bbl of oil in new recoverable reserves, and to date have added 37,000 bbl/day to the joint venture's production. In addition, the 3-D interpretations have resulted in a sizable inventory of wells for future development drilling. The new 3-Dmore » interpretations provided more accurate pictures of fault patterns, fluid contacts, channel trends, stratigraphic continuity, and velocity/amplitude anomalies. In addition, the 3-D data were invaluable in designing low risk, directional well trajectories to tap relatively thin oil legs under large gas caps. Wells often were programmed to hit several objectives at their respective gas/oil contacts, resulting in maximized net oil sand pays and reducing the risk of gas production. In order to do this, directional [open quotes]sharpshooting,[close quotes] accurate depth conversion of the seismic time maps, was critical. By using the 3-D seismic, checkshot, and sonic data to develop a variable velocity space, well-top prognoses within 50 ft at depths of 6,000-10,000 ft were possible, and were key to the success of the program. As the joint venture acreage becomes more mature, development wells will be drilled for smaller numbers of stacked objectives, and sometimes for single sands. Highly accurate 3-D interpretations and depth conversions will become even more critical in order to tap thinner pay zones in a cost-effect manner.« less
Emergency seismic and CGPS networks: a first employment for the L'Aquila Mw 6.3 earthquake
Abruzzese, L.; Avallone, A.; Cecere, G.; Cattaneo, M.; Cardinale, V.; Castagnozzi, A.; Cogliano, R.; Criscuoli, F.; D'Agostino, N.; D'Ambrosio, C.; de Luca, G.; D'Anastasio, E.; Falco, L.; Flammia, V.; Migliari, F.; Minichiello, F.; Memmolo, A.; Monachesi, G.; Moschillo, R.; Pignone, M.; Pucillo, S.; Selvaggi, G.; Zarrilli, L.; Delladio, A.; Govoni, A.; Franceschi, D.; de Martin, M.; Moretti, M.
During the last 2 years, the Istituto Nazionale di Geofisica e Vulcanologia (INGV) developed an important real-time temporary seismic network infrastructure in order to densify the Italian National Seismic Network in epicentral areas thus enhancing the localization of the micro-seismicity after main earthquake events. This real-time temporary seismic network is constituted by various mobile and autonomous seismic stations that in group of three are telemetered to a Very Small Aperture Terminal (VSAT). This system uses a dedicated bandwidth on UHF, Wi-Fi and satellite frequency that allows the data flow in real-time at INGV centre in Rome (and Grottaminarda as backup center). The deployment of the seismic network is managed in a geographical information systems (GIS) by particular scenarios that visualizes, for the epicentral area, information about instrumental seismicity, seismic risk, macroseismic felts and territorial data. Starting from digital terrain model, the surface spatial analysis (Viewshed, Observer Point) allows the geographic arrangement of the stations and relative scenarios. The April, 6th, 2009 Mw 6.3 L'Aquila destructive earthquake represented the first real-case to test the entire emergency seismic network infrastructure. Less than 6 hours after the earthquake occurrence, a first accelerometer station was already sending data at INGV seismic monitoring headquarters. A total number of 9 seismic stations have been installed within 3 days after the earthquake. Furthermore, 5 permanent GPS stations have been installed in the epicentral area within 1 to 9 days after the main shock to detect the post-seismic deformation induced by the earthquake. We will show and describe the details of the Emergency Seismic Network infrastructure, and the first results from the collected data.
Program and plans of the U.S. Geological Survey for producing information needed in National Seismic hazards and risk assessment, fiscal years 1980-84
Hays, Walter W.
In accordance with the provisions of the Earthquake Hazards Reduction Act of 1977 (Public Law 95-124), the U.S. Geological Survey has developed comprehensive plans for producing information needed to assess seismic hazards and risk on a national scale in fiscal years 1980-84. These plans are based on a review of the needs of Federal Government agencies, State and local government agencies, engineers and scientists engaged in consulting and research, professional organizations and societies, model code groups, and others. The Earthquake Hazards Reduction Act provided an unprecedented opportunity for participation in a national program by representatives of State and local governments, business and industry, the design professions, and the research community. The USGS and the NSF (National Science Foundation) have major roles in the national program. The ultimate goal of the program is to reduce losses from earthquakes. Implementation of USGS research in the Earthquake Hazards Reduction Program requires the close coordination of responsibility between Federal, State and local governments. The projected research plan in national seismic hazards and risk for fiscal years 1980-84 will be accomplished by USGS and non-USGS scientists and engineers. The latter group will participate through grants and contracts. The research plan calls for (1) national maps based on existing methods, (2) improved definition of earthquake source zones nationwide, (3) development of improved methodology, (4) regional maps based on the improved methodology, and (5) post-earthquake investigations. Maps and reports designed to meet the needs, priorities, concerns, and recommendations of various user groups will be the products of this research and provide the technical basis for improved implementation.
Implementing a National Scottish Digital Health & Wellbeing Service at Scale: A Qualitative Study of Stakeholders' Views.
Agbakoba, Ruth; McGee-Lennon, Marilyn; Bouamrane, Matt-Mouley; Watson, Nicholas; Mair, Frances
Digital technologies are being used as part of international efforts to revolutionize healthcare in order to meet increasing demands such as the rising burden of chronic disease and ageing populations. In Scotland there is a government push towards a national service (Living It Up) as a single point of reference where citizens can access information, products and services to support their health and wellbeing. The aim of the study is to examine implementation issues including the challenges or facilitators which can help to sustain this intervention. We gathered data in three ways: a) participant observation to gain an understanding of LiU (N=16); b) in-depth interviews (N=21) with stakeholders involved in the process; and c) analysis of documentary evidence about the progress of the implementation (N=45). Barriers included the need to "work at risk" due to delays in financing, inadequate infrastructure and skill-set deficiencies, whilst facilitators included trusted relationships, champions and a push towards normalisation. The findings suggest that a Scottish ehealth service is achievable but identifies key considerations for future large scale initiatives.
Martian seismicity
Phillips, Roger J.; Grimm, Robert E.
The design and ultimate success of network seismology experiments on Mars depends on the present level of Martian seismicity. Volcanic and tectonic landforms observed from imaging experiments show that Mars must have been a seismically active planet in the past and there is no reason to discount the notion that Mars is seismically active today but at a lower level of activity. Models are explored for present day Mars seismicity. Depending on the sensitivity and geometry of a seismic network and the attenuation and scattering properties of the interior, it appears that a reasonable number of Martian seismic events would be detected over the period of a decade. The thermoelastic cooling mechanism as estimated is surely a lower bound, and a more refined estimate would take into account specifically the regional cooling of Tharsis and lead to a higher frequency of seismic events.
Modernization of the USGS Hawaiian Volcano Observatory Seismic Processing Infrastructure
Antolik, L.; Shiro, B.; Friberg, P. A.
The USGS Hawaiian Volcano Observatory (HVO) operates a Tier 1 Advanced National Seismic System (ANSS) seismic network to monitor, characterize, and report on volcanic and earthquake activity in the State of Hawaii. Upgrades at the observatory since 2009 have improved the digital telemetry network, computing resources, and seismic data processing with the adoption of the ANSS Quake Management System (AQMS) system. HVO aims to build on these efforts by further modernizing its seismic processing infrastructure and strengthen its ability to meet ANSS performance standards. Most notably, this will also allow HVO to support redundant systems, both onsite and offsite, in order to provide better continuity of operation during intermittent power and network outages. We are in the process of implementing a number of upgrades and improvements on HVO's seismic processing infrastructure, including: 1) Virtualization of AQMS physical servers; 2) Migration of server operating systems from Solaris to Linux; 3) Consolidation of AQMS real-time and post-processing services to a single server; 4) Upgrading database from Oracle 10 to Oracle 12; and 5) Upgrading to the latest Earthworm and AQMS software. These improvements will make server administration more efficient, minimize hardware resources required by AQMS, simplify the Oracle replication setup, and provide better integration with HVO's existing state of health monitoring tools and backup system. Ultimately, it will provide HVO with the latest and most secure software available while making the software easier to deploy and support.
Beyond pilotitis: taking digital health interventions to the national level in China and Uganda.
Huang, Fei; Blaschke, Sean; Lucas, Henry
Innovation theory has focused on the adoption of new products or services by individuals and their market-driven diffusion to the population at large. However, major health sector innovations typically emerge from negotiations between diverse stakeholders who compete to impose or at least prioritise their preferred version of that innovation. Thus, while many digital health interventions have succeeded in terms of adoption by a substantial number of providers and patients, they have generally failed to gain the level of acceptance required for their integration into national health systems that would promote sustainability and population-wide application. The area of innovation considered here relates to a growing number of success stories that have created considerable enthusiasm among donors, international agencies, and governments for the potential role of ICTs in transforming weak national health information systems in middle and low income countries. This article uses a case study approach to consider the assumptions, institutional as well as technical, underlying this enthusiasm and explores possible ways in which outcomes might be improved. Literature review and case study analysis. The two systems considered have had considerable success in terms of gaining and maintaining government support and addressing the concerns of providers without compromising their core elements. In Uganda, the system has flourished in spite of severe resource constraints, using a participatory approach that has encouraged a high level of community engagement. In China, concern with past failures generated the political will to build a high quality surveillance system, using the latest technology and drawing on a highly skilled human resource base. Both example stress the importance of recognising the political, social and historical context within which information systems have to function. Implementers need to focus as much on the perceptions, attitudes and needs of stakeholders
Seismic Ecology
Seleznev, V. S.; Soloviev, V. M.; Emanov, A. F.
The paper is devoted to researches of influence of seismic actions for industrial and civil buildings and people. The seismic actions bring influence directly on the people (vibration actions, force shocks at earthquakes) or indirectly through various build- ings and the constructions and can be strong (be felt by people) and weak (be fixed by sensing devices). The great number of work is devoted to influence of violent seismic actions (first of all of earthquakes) on people and various constructions. This work is devoted to study weak, but long seismic actions on various buildings and people. There is a need to take into account seismic oscillations, acting on the territory, at construction of various buildings on urbanized territories. Essential influence, except for violent earthquakes, man-caused seismic actions: the explosions, seismic noise, emitted by plant facilities and moving transport, radiation from high-rise buildings and constructions under action of a wind, etc. can exert. Materials on increase of man- caused seismicity in a number of regions in Russia, which earlier were not seismic, are presented in the paper. Along with maps of seismic microzoning maps to be built indicating a variation of amplitude spectra of seismic noise within day, months, years. The presence of an information about amplitudes and frequencies of oscillations from possible earthquakes and man-caused oscillations in concrete regions allows carry- ing out soundly designing and construction of industrial and civil housing projects. The construction of buildings even in not seismically dangerous regions, which have one from resonance frequencies coincident on magnitude to frequency of oscillations, emitted in this place by man-caused objects, can end in failure of these buildings and heaviest consequences for the people.

The improved broadband Real-Time Seismic Network in Romania
Neagoe, C.; Ionescu, C.
Starting with 2002 the National Institute for Earth Physics (NIEP) has developed its real-time digital seismic network. This network consists of 96 seismic stations of which 48 broad band and short period stations and two seismic arrays are transmitted in real-time. The real time seismic stations are equipped with Quanterra Q330 and K2 digitizers, broadband seismometers (STS2, CMG40T, CMG 3ESP, CMG3T) and strong motions sensors Kinemetrics episensors (+/- 2g). SeedLink and AntelopeTM (installed on MARMOT) program packages are used for real-time (RT) data acquisition and exchange. The communication from digital seismic stations to the National Data Center in Bucharest is assured by 5 providers (GPRS, VPN, satellite communication, radio lease line and internet), which will assure the back-up communications lines. The processing centre runs BRTT's AntelopeTM 4.10 data acquisition and processing software on 2 workstations for real-time processing and post processing. The Antelope Real-Time System is also providing automatic event detection, arrival picking, event location and magnitude calculation. It provides graphical display and reporting within near-real-time after a local or regional event occurred. Also at the data center was implemented a system to collect macroseismic information using the internet on which macro seismic intensity maps are generated. In the near future at the data center will be install Seiscomp 3 data acquisition processing software on a workstation. The software will run in parallel with Antelope software as a back-up. The present network will be expanded in the near future. In the first half of 2009 NIEP will install 8 additional broad band stations in Romanian territory, which also will be transmitted to the data center in real time. The Romanian Seismic Network is permanently exchanging real -time waveform data with IRIS, ORFEUS and different European countries through internet. In Romania, magnitude and location of an earthquake are now
Alaska Volcano Observatory Seismic Network Data Availability
Dixon, J. P.; Haney, M. M.; McNutt, S. R.; Power, J. A.; Prejean, S. G.; Searcy, C. K.; Stihler, S. D.; West, M. E.
The Alaska Volcano Observatory (AVO) established in 1988 as a cooperative program of the U.S. Geological Survey, the Geophysical Institute at the University of Alaska Fairbanks, and the Alaska Division of Geological and Geophysical Surveys, monitors active volcanoes in Alaska. Thirty-three volcanoes are currently monitored by a seismograph network consisting of 193 stations, of which 40 are three-component stations. The current state of AVO’s seismic network, and data processing and availability are summarized in the annual AVO seismological bulletin, Catalog of Earthquake Hypocenters at Alaska Volcanoes, published as a USGS Data Series (most recent at http://pubs.usgs.gov/ds/467). Despite a rich seismic data set for 12 VEI 2 or greater eruptions, and over 80,000 located earthquakes in the last 21 years, the volcanic seismicity in the Aleutian Arc remains understudied. Initially, AVO seismic data were only provided via a data supplement as part of the annual bulletin, or upon request. Over the last few years, AVO has made seismic data more available with the objective of increasing volcano seismic research on the Aleutian Arc. The complete AVO earthquake catalog data are now available through the annual AVO bulletin and have been submitted monthly to the on-line Advanced National Seismic System (ANSS) composite catalog since 2008. Segmented waveform data for all catalog earthquakes are available upon request and efforts are underway to make this archive web accessible as well. Continuous data were first archived using a tape backup, but the availability of low cost digital storage media made a waveform backup of continuous data a reality. Currently the continuous AVO waveform data can be found in several forms. Since late 2002, AVO has burned all continuous waveform data to DVDs, as well as storing these data in Antelope databases at the Geophysical Institute. Beginning in 2005, data have been available through a Winston Wave Server housed at the USGS in
ENVIRONMENTAL REVIEWS AND CASE STUDIES: Addressing the Public Outreach Responsibilities of the National Historic Preservation Act: Argonne National Laboratory’s Box Digital Display Platform
O’Rourke, Daniel J.; Weber, Cory C.; Richmond, Pamela D.
Federal agencies are made responsible for managing the historic properties under their jurisdiction by the National Historic Preservation Act of 1966, as amended. A component of this responsibility is to mitigate the effect of a federal undertaking on historic properties through mitigation often through documentation. Providing public access to this documentation has always been a challenge. To address the issue of public access to mitigation information, personnel from Argonne National Laboratory created the Box Digital Display Platform, a system for communicating information about historic properties to the public. The platform, developed for the US Army Dugway Proving Ground, uses shortmore » introductory videos to present a topic but can also incorporate photos, drawings, GIS information, and documents. The system operates from a small, self-contained computer that can be attached to any digital monitor via an HDMI cable. The system relies on web-based software that allows the information to be republished as a touch-screen device application or as a website. The system does not connect to the Internet, and this increases security and eliminates the software maintenance fees associated with websites. The platform is designed to incorporate the products of past documentation to make this information more accessible to the public; specifically those documentations developed using the Historic American Building Survey/ Historic American Engineering Record (HABS/HAER) standards. Argonne National Laboratory’s Box Digital Display Platform can assist federal agencies in complying with the requirements of the National Historic Preservation Act.

A digital model for planning water management at Benton Lake National Wildlife Refuge, west-central Montana
Nimick, David A.; McCarthy, Peter M.; Fields, Vanessa
Benton Lake National Wildlife Refuge is an important area for waterfowl production and migratory stopover in west-central Montana. Eight wetland units covering about 5,600 acres are the essential features of the refuge. Water availability for the wetland units can be uncertain owing to the large natural variations in precipitation and runoff and the high cost of pumping supplemental water. The U.S. Geological Survey, in cooperation with the U.S. Fish and Wildlife Service, has developed a digital model for planning water management. The model can simulate strategies for water transfers among the eight wetland units and account for variability in runoff and pumped water. This report describes this digital model, which uses a water-accounting spreadsheet to track inputs and outputs to each of the wetland units of Benton Lake National Wildlife Refuge. Inputs to the model include (1) monthly values for precipitation, pumped water, runoff, and evaporation; (2) water-level/capacity data for each wetland unit; and (3) the pan-evaporation coefficient. Outputs include monthly water volume and flooded surface area for each unit for as many as 5 consecutive years. The digital model was calibrated by comparing simulated and historical measured water volumes for specific test years.
The GEOSCOPE broadband seismic observatory
Douet, Vincent; Vallée, Martin; Zigone, Dimitri; Bonaimé, Sébastien; Stutzmann, Eléonore; Maggi, Alessia; Pardo, Constanza; Bernard, Armelle; Leroy, Nicolas; Pesqueira, Frédéric; Lévêque, Jean-Jacques; Thoré, Jean-Yves; Bes de Berc, Maxime; Sayadi, Jihane
The GEOSCOPE observatory has provided continuous broadband data to the scientific community for the past 34 years. The 31 operational GEOSCOPE stations are installed in 17 countries, across all continents and on islands throughout the oceans. They are equipped with three component very broadband seismometers (STS1, T240 or STS2) and 24 or 26 bit digitizers (Q330HR). Seismometers are installed with warpless base plates, which decrease long period noise on horizontal components by up to 15dB. All stations send data in real time to the IPGP data center, which transmits them automatically to other data centers (FDSN/IRIS-DMC and RESIF) and tsunami warning centers. In 2016, three stations are expected to be installed or re-installed: in Western China (WUS station), in Saint Pierre and Miquelon Island (off the East coast of Canada) and in Walis and Futuna (SouthWest Pacific Ocean). The waveform data are technically validated by IPGP (25 stations) or EOST (6 stations) in order to check their continuity and integrity. Scientific data validation is also performed by analyzing seismic noise level of the continuous data and by comparing real and synthetic earthquake waveforms (body waves). After these validations, data are archived by the IPGP data center in Paris. They are made available to the international scientific community through different interfaces (see details on http://geoscope.ipgp.fr). Data are duplicated at the FDSN/IRIS-DMC data center and a similar duplication at the French national data center RESIF will be operational in 2016. The GEOSCOPE broadband seismic observatory also provides near-real time information on global moderate-to-large seismicity (above magnitude 5.5-6) through the automated application of the SCARDEC method (Vallée et al., 2011). By using global data from the FDSN - in particular from GEOSCOPE and IRIS/USGS stations -, earthquake source parameters (depth, moment magnitude, focal mechanism, source time function) are determined about 45
Observations and modeling of seismic background noise
Peterson, Jon R.
The preparation of this report had two purposes. One was to present a catalog of seismic background noise spectra obtained from a worldwide network of seismograph stations. The other purpose was to refine and document models of seismic background noise that have been in use for several years. The second objective was, in fact, the principal reason that this study was initiated and influenced the procedures used in collecting and processing the data.With a single exception, all of the data used in this study were extracted from the digital data archive at the U.S. Geological Survey's Albuquerque Seismological Laboratory (ASL). This archive dates from 1972 when ASL first began deploying digital seismograph systems and collecting and distributing digital data under the sponsorship of the Defense Advanced Research Projects Agency (DARPA). There have been many changes and additions to the global seismograph networks during the past twenty years, but perhaps none as significant as the current deployment of very broadband seismographs by the U.S. Geological Survey (USGS) and the University of California San Diego (UCSD) under the scientific direction of the IRIS consortium. The new data acquisition systems have extended the bandwidth and resolution of seismic recording, and they utilize high-density recording media that permit the continuous recording of broadband data. The data improvements and continuous recording greatly benefit and simplify surveys of seismic background noise.Although there are many other sources of digital data, the ASL archive data were used almost exclusively because of accessibility and because the data systems and their calibration are well documented for the most part. Fortunately, the ASL archive contains high-quality data from other stations in addition to those deployed by the USGS. Included are data from UCSD IRIS/IDA stations, the Regional Seismic Test Network (RSTN) deployed by Sandia National Laboratories (SNL), and the TERRAscope network
Reassessment of the Seismicity and seismic hazards of Libya
Ben Suleman, A.; Elmeladi, A.
The tectonic evolution of Libya, located at the northern extreme of the African continent, has yielded a complex crustal structure that is composed of a series of basins and uplifts. The present day deformation of Libya is the result of the Eurasia-Africa continental collision. At the end of the year 2005, The Libyan National Seismological Network was established to monitor local, regional and teleseismic activities, as well as to provide high quality data for research projects both locally and on the regional and global scale. This study aims to discuss the seismicity of Libya by using the new data from the Libyan national seismological network and to focus on the seismic hazards. At first glance the seismic activity map shows dominant trends of seismicity with most of the seismic activity concentrated along the northern coastal areas. Four major seismic trends were quite noticeable. A first trend is a NW-SE direction coinciding with the eastern boarder of the Hun Graben. A second trend is also a NW-SE direction in the offshore area and might be a continuation of this trend. The other two trends were located in the western Gulf of Sirt and Cyrenaica platform. The rest of seismicity is diffuse either offshore or in land, with no good correlation with well-mapped faults. Detailed investigations of the Libyan seismicity indicates that the Libya has experienced earthquakes of varying magnitudes and that there is definitely a certain amount of seismic risk involved in engineering projects, particularly in the northern regions. Detailed investigation of the distribution of the Libyan earthquakes in space and time along with all other geological considerations suggested the classification of the country into four seismic zones with the Hun graben zone being the most seismically active zone.
A digital atlas of hydrocarbon accumulations within and adjacent to the National Petroleum Reserve - Alaska (NPRA)
Kumar, Naresh; Bird, Kenneth J.; Nelson, Philip H.; Grow, John A.; Evans, Kevin R.
The United States Geological Survey (USGS) has initiated a project to reassess the hydrocarbon potential of the NPRA. Although exploration for hydrocarbons in the NPRA was initiated in 1944, it has taken fifty years for the first commercial discovery to be made. That discovery, the Alpine field (projected recoverable reserves of 430 million barrels), was made in 1994 along the eastern boundary of the NPRA. This field produces from a formation heretofore considered to be mostly a source rock. The Alpine discovery made such a reassessment necessary. As part of this assessment, we have compiled stratigraphic, structural, petrophysical, and seismic data related to nineteen accumulations within and nearby the NPRA. The goal is to provide basic documentation and a set of analog accumulations for the new assessment. The first two displays of this atlas consist of a location map and a stratigraphic column showing the stratigraphic settings for the primary reservoir and source rocks for these accumulations. The third display is a table listing each accumulation and providing the hydrocarbon fluid type, reservoir, operator, status, and discovery well and date for each. Compilation of basic information for each individual accumulation follows these displays. A typical compilation includes a structurecontour map on or near the reservoir horizon, a log display of the discovery well with reservoir characteristics along with figures for recoverable volumes, and one or two seismic lines across or near the accumulation.
Updated Colombian Seismic Hazard Map
Eraso, J.; Arcila, M.; Romero, J.; Dimate, C.; Bermúdez, M. L.; Alvarado, C.
The Colombian seismic hazard map used by the National Building Code (NSR-98) in effect until 2009 was developed in 1996. Since then, the National Seismological Network of Colombia has improved in both coverage and technology providing fifteen years of additional seismic records. These improvements have allowed a better understanding of the regional geology and tectonics which in addition to the seismic activity in Colombia with destructive effects has motivated the interest and the need to develop a new seismic hazard assessment in this country. Taking advantage of new instrumental information sources such as new broad band stations of the National Seismological Network, new historical seismicity data, standardized global databases availability, and in general, of advances in models and techniques, a new Colombian seismic hazard map was developed. A PSHA model was applied. The use of the PSHA model is because it incorporates the effects of all seismic sources that may affect a particular site solving the uncertainties caused by the parameters and assumptions defined in this kind of studies. First, the seismic sources geometry and a complete and homogeneous seismic catalog were defined; the parameters of seismic rate of each one of the seismic sources occurrence were calculated establishing a national seismotectonic model. Several of attenuation-distance relationships were selected depending on the type of seismicity considered. The seismic hazard was estimated using the CRISIS2007 software created by the Engineering Institute of the Universidad Nacional Autónoma de México -UNAM (National Autonomous University of Mexico). A uniformly spaced grid each 0.1° was used to calculate the peak ground acceleration (PGA) and response spectral values at 0.1, 0.2, 0.3, 0.5, 0.75, 1, 1.5, 2, 2.5 and 3.0 seconds with return periods of 75, 225, 475, 975 and 2475 years. For each site, a uniform hazard spectrum and exceedance rate curves were calculated. With the results, it is
The use of digital imaging, video conferencing, and telepathology in histopathology: a national survey.
Dennis, T; Start, R D; Cross, S S
To undertake a large scale survey of histopathologists in the UK to determine the current infrastructure, training, and attitudes to digital pathology. A postal questionnaire was sent to 500 consultant histopathologists randomly selected from the membership of the Royal College of Pathologists in the UK. There was a response rate of 47%. Sixty four per cent of respondents had a digital camera mounted on their microscope, but only 12% had any sort of telepathology equipment. Thirty per cent used digital images in electronic presentations at meetings at least once a year and only 24% had ever used telepathology in a diagnostic situation. Fifty nine per cent had received no training in digital imaging. Fifty eight per cent felt that the medicolegal implications of duty of care were a barrier to its use. A large proportion of pathologists (69%) were interested in using video conferencing for remote attendance at multidisciplinary team meetings. There is a reasonable level of equipment and communications infrastructure among histopathologists in the UK but a very low level of training. There is resistance to the use of telepathology in the diagnostic context but enthusiasm for the use of video conferencing in multidisciplinary team meetings.

Conclusions: There is a reasonable level of equipment and communications infrastructure among histopathologists in the UK but a very low level of training. There is resistance to the use of telepathology in the diagnostic context but enthusiasm for the use of video conferencing in multidisciplinary team meetings. PMID:15735155

Geology of Point Reyes National Seashore and vicinity, California: a digital database
Clark, Jospeh C.; Brabb, Earl E.
This Open-File report is a digital geologic map database. This pamphlet serves to introduce and describe the digital data. There is no paper map included in the Open-File report. The report does include, however, a PostScript plot file containing an image of the geologic map sheet with explanation, as well as the accompanying text describing the geology of the area. For those interested in a paper plot of information contained in the database or in obtaining the PostScript plot files, please see the section entitled 'For Those Who Aren't Familiar With Digital Geologic Map Databases' below. This digital map database, compiled from previously published and unpublished data and new mapping by the authors, represents the general distribution of surficial deposits and rock units in Point Reyes and surrounding areas. Together with the accompanying text file (pr-geo.txt or pr-geo.ps), it provides current information on the stratigraphy and structural geology of the area covered. The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps limits the spatial resolution (scale) of the database to 1:48,000 or smaller.

Romanian Data Center: A modern way for seismic monitoring
Neagoe, Cristian; Marius Manea, Liviu; Ionescu, Constantin
The main seismic survey of Romania is performed by the National Institute for Earth Physics (NIEP) which operates a real-time digital seismic network. The NIEP real-time network currently consists of 102 stations and two seismic arrays equipped with different high quality digitizers (Kinemetrics K2, Quanterra Q330, Quanterra Q330HR, PS6-26, Basalt), broadband and short period seismometers (CMG3ESP, CMG40T, KS2000, KS54000, KS2000, CMG3T,STS2, SH-1, S13, Mark l4c, Ranger, gs21, Mark l22) and acceleration sensors (Episensor Kinemetrics). The data are transmitted at the National Data Center (NDC) and Eforie Nord (EFOR) Seismic Observatory. EFOR is the back-up for the NDC and also a monitoring center for the Black Sea tsunami events. NIEP is a data acquisition node for the seismic network of Moldova (FDSN code MD) composed of five seismic stations. NIEP has installed in the northern part of Bulgaria eight seismic stations equipped with broadband sensors and Episensors and nine accelerometers (Episensors) installed in nine districts along the Danube River. All the data are acquired at NIEP for Early Warning System and for primary estimation of the earthquake parameters. The real-time acquisition (RT) and data exchange is done by Antelope software and Seedlink (from Seiscomp3). The real-time data communication is ensured by different types of transmission: GPRS, satellite, radio, Internet and a dedicated line provided by a governmental network. For data processing and analysis at the two data centers Antelope 5.2 TM is being used running on 3 workstations: one from a CentOS platform and two on MacOS. Also a Seiscomp3 server stands as back-up for Antelope 5.2 Both acquisition and analysis of seismic data systems produce information about local and global parameters of earthquakes. In addition, Antelope is used for manual processing (event association, calculation of magnitude, creating a database, sending seismic bulletins, calculation of PGA and PGV, etc.), generating
Seismic seiches
McGarr, Arthur; Gupta, Harsh K.
Seismic seiche is a term first used by Kvale (1955) to discuss oscillations of lake levels in Norway and England caused by the Assam earthquake of August 15, 1950. This definition has since been generalized to apply to standing waves set up in closed, or partially closed, bodies of water including rivers, shipping channels, lakes, swimming pools and tanks due to the passage of seismic waves from an earthquake.
Global Seismicity: Three New Maps Compiled with Geographic Information Systems
Lowman, Paul D., Jr.; Montgomery, Brian C.
This paper presents three new maps of global seismicity compiled from NOAA digital data, covering the interval 1963-1998, with three different magnitude ranges (mb): greater than 3.5, less than 3.5, and all detectable magnitudes. A commercially available geographic information system (GIS) was used as the database manager. Epicenter locations were acquired from a CD-ROM supplied by the National Geophysical Data Center. A methodology is presented that can be followed by general users. The implications of the maps are discussed, including the limitations of conventional plate models, and the different tectonic behavior of continental vs. oceanic lithosphere. Several little-known areas of intraplate or passive margin seismicity are also discussed, possibly expressing horizontal compression generated by ridge push.
Applications of Digitized 3-D Position-Sensitive CdZnTe Spectrometers for National Security and Nuclear Nonproliferation
Streicher, Michael W.
A nuclear weapon detonation remains one of the gravest threats to the global community. Although the likelihood of a nuclear event remains small, the economic and political ramifications of an event are vast. The surest way to reduce the probability of an incident is to account for the special nuclear materials (SNM) which can be used to produce a nuclear weapon. Materials which can be used to manufacture a radiological dispersion device ("dirty bomb") must also be monitored. Rapidly-deployable, commercially-available, room-temperature imaging gamma-ray spectrometers are improving the ability of authorities to intelligently and quickly respond to threats. New electronics which digitally-sample the radiation-induced signals in CdZnTe detectors have expanded the capabilities of these sensors. This thesis explores national security applications where digital readout of CdZnTe detectors significantly enhances capabilities. Radioactive sources can be detected more quickly using digitally-sampled CdZnTe detector due to the improved energy resolution. The excellent energy resolution also improves the accuracy of measurements of uranium enrichment and allows users to measure plutonium grade. Small differences in the recorded gamma-ray energy spectrum can be used to estimate the effective atomic number and mass thickness of materials shielding SNM sources. Improved position resolution of gamma-ray interactions through digital readout allows high resolution gamma-ray images of SNM revealing information about the source configuration. CdZnTe sensors can detect the presence of neutrons, indirectly, through measurement of gamma rays released during capture of thermal neutrons by Cd-113 or inelastic scattering with any constituent nuclei. Fast neutrons, such as those released following fission, can be directly detected through elastic scattering interactions in the detector. Neutrons are a strong indicator of fissile material, and the background neutron rate is much lower than

High prevalence of self-reported symptoms of digital ischemia in elite male volleyball players in the Netherlands: a cross-sectional national survey.
van de Pol, Daan; Kuijer, P Paul F M; Langenhorst, Ton; Maas, Mario
In the past 3 years, 6 volleyball players with ischemic digits and small microemboli in the digital arteries of the dominant hand presented themselves in our hospital. These complaints were caused by an aneurysmatic dilation of the posterior circumflex humeral artery (PCHA) with distal occlusion and digital emboli in the isolateral limb. All were elite male volleyball players active in the national top league. Little is known about the exact symptoms associated with PCHA pathological lesions with digital emboli (PCHAP with DE) and its prevalence in elite volleyball players. If vascular injury can be identified at an early stage, thromboembolic complications and irreversible damage to the digits might be prevented. To assess the prevalence of symptoms that are consistent with digital ischemia and may be caused by PCHAP with DE in elite male volleyball players in the Netherlands. Cross-sectional study; Level of evidence, 3. A questionnaire survey was performed among elite volleyball players in the Dutch national top league and the Dutch beach volleyball team. The questionnaire was constructed using literature-based data on symptoms associated with PCHAP with DE, together with data retrieved from medical files. A total of 99 of the 107 athletes participated, with a response rate of 93%. The most frequently reported symptoms associated with PCHAP with DE were cold, blue, or pale digits in the dominant hand during or immediately after practice or competition. The prevalence of these symptoms ranged from 11% to 27%. The prevalence of cold digits during practice and competition was 27%. The prevalence of cold, blue, and pale digits during or immediately after practice and competition was 12%. An unexpectedly high percentage of elite volleyball players reported symptoms that are associated with PCHAP with DE in the dominant hand. Because these athletes are considered potentially at risk for developing critical digital ischemia, further analysis of the presence of digital

Mikhnevo: from seismic station no. 1 to a modern geophysical observatory
Adushkin, V. V.; Ovchinnikov, V. M.; Sanina, I. A.; Riznichenko, O. Yu.
The Mikhnevo seismic station was founded in accordance with directive no. 1134 RS of the Council of Ministers of the Soviet Union of February 6, 1954. The station, installed south of Moscow, began its operations on monitoring nuclear tests in the United States and England in 1954. For dozens of years this station was the leading experimental base for elaborating new technical solutions and methods for monitoring nuclear explosions, equipped with modern seismological instruments. At present, the focus of activities has been moved from military applications to fundamental geophysical research. The station preserves its leading position in seismological observations due to the development of national high-performance digital instruments and creation of the small-aperture seismic array, the only one in the central part of European Russia, which is capable of recording weak seismic events with M L ≥ 1.5 within a distance of 100 km.
Romanian Complex Data Center for Dense Seismic network
Neagoe, Cristian; Ionescu, Constantin; Marius Manea, Liviu
Since 2002 the National Institute for Earth Physics (NIEP) developed its own real-time digital seismic network: consisting of 96 seismic stations of which 35 are broadband sensors and 24 stations equipped with short period sensors and two arrays earthquakes that transmit data in real time at the National Data Center (NDC) and Eforie Nord (EFOR) Seismic Observatory. EFOR is the back-up for the NDC and also a monitoring center for Black Sea tsunamis. Seismic stations are equipped with Quanterra Q330 and K2 digitizers, broadband seismometers (STS2, CMG40T, CMG 3ESP, CMG3T) and acceleration sensors Episensor Kinemetrics (+ / - 2G). SeedLink who is a part of Seiscomp2.5 and Antelope are software packages used for acquisition in real time (RT) and for data exchange. Communication of digital seismic stations to the National Data Center in Bucharest and Seismic Observatory Eforie Nord is assured by 5 providers (GPRS, VPN, satellite radio and Internet communication). For acquisition and data processing at the two centers of reception and processing is used AntelopeTM 4.11 running on 2 workstations: one for real-time and other for offline processing and also a Seiscomp 3 server that works as back-up for Antelope 4.11 Both acquisition and analysis of seismic data systems produced information about local and global parameters of earthquakes, in addition Antelope is used for manual processing (association events, the calculation of magnitude, creating a database, sending seismic bulletins, calculation of PGA and PGV , etc.), generating ShakeMap products and interacts with global data centers. In order to make all this information easily available across the Web and also lay the grounds for a more modular and flexible development environment the National Data Center developed tools to enable centralizing of data from software such as Antelope which is using a dedicated database system ( Datascope, a database system based on text files ) to a more general-purpose database, My
Diffusion of the Digital Health Self-Tracking Movement in Canada: Results of a National Survey.
Paré, Guy; Leaver, Chad; Bourget, Claire
With the ever-increasing availability of mobile apps, consumer wearables, and smart medical devices, more and more individuals are self-tracking and managing their personal health data. The aim of this study was to investigate the diffusion of the digital self-tracking movement in Canada. It provides a comprehensive, yet detailed account of this phenomenon. It examines the profile of digital self-trackers, traditional self-trackers, and nontrackers, further investigating the primary motivations for self-tracking and reasons for nontracking; barriers to adoption of connected care technologies; users' appreciation of their self-tracking devices, including what they perceive to be the main benefits; factors that influence people's intention to continue using connected care technologies in the future; and the reasons for usage discontinuance. We conducted an online survey with a sample of 4109 Canadian adults, one of the largest ever. To ensure a representative sample, quota method was used (gender, age), following stratification by region. The maximum margin of error is estimated at 1.6%, 19 times out of 20. Our findings reveal that 66.20% (2720/4109) of our respondents regularly self-track one or more aspects of their health. About one in 4 respondents (1014/4109, 24.68%) currently owns a wearable or smart medical device, and 57.20% (580/1014) use their devices on a regular basis for self-tracking purposes. Digital self-trackers are typically young or mature adults, healthy, employed, university educated, with an annual family income of over $80,000 CAD. The most popular reported device is the fitness tracker or smartwatch that can capture a range of parameters. Currently, mobile apps and digital self-tracking devices are mainly used to monitor physical activity (856/1669, 51.13%), nutrition (545/1669, 32.65%), sleep patterns (482/1669, 28.88%) and, to a much lesser extent, cardiovascular and pulmonary biomarkers (215/1669, 12.88%), medication intake (126/1669, 7

Angola seismicity
Neto, Francisco António Pereira; França, George Sand; Condori, Cristobal; Sant'Anna Marotta, Giuliano; Chimpliganond, Cristiano Naibert
This work describes the development of the Angolan earthquake catalog and seismicity distribution in the Southwestern African Plate, in Angola. This region is one of the least seismically active, even for stable continental regions (SCRs) in the world. The maximum known earthquake had a magnitude of 6.0 Ms, while events with magnitudes of 4.5 have return period of about 10 years. Events with magnitude 5 and above occur with return period of about 20 years. Five seismic zones can be confirmed in Angola, within and along craton edges and in the sedimentary basins including offshore. Overall, the exposed cratonic regions tend to have more earthquakes compared to other regions such as sedimentary basins. Earthquakes tend to occur in Archaic rocks, especially inside preexisting weakness zones and in tectonic-magmatic reactivation zones of Mesozoic and Meso-Cenozoic, associated with the installation of a wide variety of intrusive rocks, strongly marked by intense tectonism. This fact can be explained by the models of preexisting weakness zones and stress concentration near intersecting structures. The Angolan passive margin is also a new region where seismic activity occurs. Although clear differences are found between different areas along the passive margin, in the middle near Porto Amboim city, seismic activity is more frequent compared with northwestern and southwestern regions.
Survey research with a random digit dial national mobile phone sample in Ghana: Methods and sample quality
Sefa, Eunice; Adimazoya, Edward Akolgo; Yartey, Emmanuel; Lenzi, Rachel; Tarpo, Cindy; Heward-Mills, Nii Lante; Lew, Katherine; Ampeh, Yvonne
Introduction Generating a nationally representative sample in low and middle income countries typically requires resource-intensive household level sampling with door-to-door data collection. High mobile phone penetration rates in developing countries provide new opportunities for alternative sampling and data collection methods, but there is limited information about response rates and sample biases in coverage and nonresponse using these methods. We utilized data from an interactive voice response, random-digit dial, national mobile phone survey in Ghana to calculate standardized response rates and assess representativeness of the obtained sample. Materials and methods The survey methodology was piloted in two rounds of data collection. The final survey included 18 demographic, media exposure, and health behavior questions. Call outcomes and response rates were calculated according to the American Association of Public Opinion Research guidelines. Sample characteristics, productivity, and costs per interview were calculated. Representativeness was assessed by comparing data to the Ghana Demographic and Health Survey and the National Population and Housing Census. Results The survey was fielded during a 27-day period in February-March 2017. There were 9,469 completed interviews and 3,547 partial interviews. Response, cooperation, refusal, and contact rates were 31%, 81%, 7%, and 39% respectively. Twenty-three calls were dialed to produce an eligible contact: nonresponse was substantial due to the automated calling system and dialing of many unassigned or non-working numbers. Younger, urban, better educated, and male respondents were overrepresented in the sample. Conclusions The innovative mobile phone data collection methodology yielded a large sample in a relatively short period. Response rates were comparable to other surveys, although substantial coverage bias resulted from fewer women, rural, and older residents completing the mobile phone survey in

Earthquake source imaging by high-resolution array analysis at regional distances: the 2010 M7 Haiti earthquake as seen by the Venezuela National Seismic Network
Meng, L.; Ampuero, J. P.; Rendon, H.
Back projection of teleseismic waves based on array processing has become a popular technique for earthquake source imaging,in particular to track the areas of the source that generate the strongest high frequency radiation. The technique has been previously applied to study the rupture process of the Sumatra earthquake and the supershear rupture of the Kunlun earthquakes. Here we attempt to image the Haiti earthquake using the data recorded by Venezuela National Seismic Network (VNSN). The network is composed of 22 broad-band stations with an East-West oriented geometry, and is located approximately 10 degrees away from Haiti in the perpendicular direction to the Enriquillo fault strike. This is the first opportunity to exploit the privileged position of the VNSN to study large earthquake ruptures in the Caribbean region. This is also a great opportunity to explore the back projection scheme of the crustal Pn phase at regional distances,which provides unique complementary insights to the teleseismic source inversions. The challenge in the analysis of the 2010 M7.0 Haiti earthquake is its very compact source region, possibly shorter than 30km, which is below the resolution limit of standard back projection techniques based on beamforming. Results of back projection analysis using the teleseismic USarray data reveal little details of the rupture process. To overcome the classical resolution limit we explored the Multiple Signal Classification method (MUSIC), a high-resolution array processing technique based on the signal-noise orthognality in the eigen space of the data covariance, which achieves both enhanced resolution and better ability to resolve closely spaced sources. We experiment with various synthetic earthquake scenarios to test the resolution. We find that MUSIC provides at least 3 times higher resolution than beamforming. We also study the inherent bias due to the interferences of coherent Green’s functions, which leads to a potential quantification
Induced Seismicity
Keranen, Katie M.; Weingarten, Matthew
The ability of fluid-generated subsurface stress changes to trigger earthquakes has long been recognized. However, the dramatic rise in the rate of human-induced earthquakes in the past decade has created abundant opportunities to study induced earthquakes and triggering processes. This review briefly summarizes early studies but focuses on results from induced earthquakes during the past 10 years related to fluid injection in petroleum fields. Study of these earthquakes has resulted in insights into physical processes and has identified knowledge gaps and future research directions. Induced earthquakes are challenging to identify using seismological methods, and faults and reefs strongly modulate spatial and temporal patterns of induced seismicity. However, the similarity of induced and natural seismicity provides an effective tool for studying earthquake processes. With continuing development of energy resources, increased interest in carbon sequestration, and construction of large dams, induced seismicity will continue to pose a hazard in coming years.
Modified-Symbol Digit Modalities Test for African Americans, Caribbean Black Americans and Non-Latino Whites: Nationally Representative Normative Data from the National Survey of American Life
González, Hector M.; Whitfield, Keith E.; West, Brady T.; Williams, David R.; Lichtenberg, Peter; Jackson, James S.
Normative neuropsychological data for U.S. racial/ethnic minorities is limited. Extant norms are based on small, regional groups that may not be nationally representative. The objectives of this study were to 1) provide norms for a modified Symbol Digit Modalities Test (M-SDMT) based on a nationally representative sample of African Americans, Caribbean Blacks and non-Latino Whites (NLW) living in areas with large populations of Blacks, and 2) determine significant correlates of M-SDMT performance. The M-SDMT was administered to a subset of respondents from the National Survey of American Life in standard, face-to-face interviews. M-SDMT performance was influenced by race/ethnicity, age, education, and gender. African Americans and NLW groups had similar M-SDMT performances, which differed from Caribbean Blacks. The Black ethnic differences in M-SDMT were not explained by the sociodemographic factors considered in this study. Unlike previous work, this study supports the consideration of Black ethnicity when evaluating Black neuropsychological test performance. PMID:17493782
Nowack, Robert L.; Li, Cuiping
The inversion of seismic travel-time data for radially varying media was initially investigated by Herglotz, Wiechert, and Bateman (the HWB method) in the early part of the 20th century [1]. Tomographic inversions for laterally varying media began in seismology starting in the 1970’s. This included early work by Aki, Christoffersson, and Husebye who developed an inversion technique for estimating lithospheric structure beneath a seismic array from distant earthquakes (the ACH method) [2]. Also, Alekseev and others in Russia performed early inversions of refraction data for laterally varying upper mantle structure [3]. Aki and Lee [4] developed an inversion technique using travel-time data from local earthquakes.
The National Institutes of Health Clinical Center Digital Imaging Network, Picture Archival and Communication System, and Radiology Information System.
Goldszal, A F; Brown, G K; McDonald, H J; Vucich, J J; Staab, E V
In this work, we describe the digital imaging network (DIN), picture archival and communication system (PACS), and radiology information system (RIS) currently being implemented at the Clinical Center, National Institutes of Health (NIH). These systems are presently in clinical operation. The DIN is a redundant meshed network designed to address gigabit density and expected high bandwidth requirements for image transfer and server aggregation. The PACS projected workload is 5.0 TB of new imaging data per year. Its architecture consists of a central, high-throughput Digital Imaging and Communications in Medicine (DICOM) data repository and distributed redundant array of inexpensive disks (RAID) servers employing fiber-channel technology for immediate delivery of imaging data. On demand distribution of images and reports to clinicians and researchers is accomplished via a clustered web server. The RIS follows a client-server model and provides tools to order exams, schedule resources, retrieve and review results, and generate management reports. The RIS-hospital information system (HIS) interfaces include admissions, discharges, and transfers (ATDs)/demographics, orders, appointment notifications, doctors update, and results.
Who Let the Dogs Out? Communicating First Nations Perspectives on a Canine Veterinary Intervention Through Digital Storytelling.
Schurer, Janna M; McKenzie, Christina; Okemow, Crystal; Viveros-Guzmán, Arcadio; Beatch, Heather; Jenkins, Emily J
Dog-related human injuries affect public safety and animal welfare, and occur more frequently in rural, remote, and Indigenous communities than in urban centres in Canada. Little work has been done to identify the perspectives of those people most heavily affected by this issue or to report successful dog management programs. This project was undertaken by veterinarians and public health workers with the goal of documenting First Nations perspectives on dogs, and educating other rural health workers about introducing animal management services to Indigenous communities. We recruited 10-14 residents and healthcare workers from three First Nations to take dog-related photos in their communities and participate in group interviews during the summer of 2014. Audiovisual data were synthesised into four digital stories exploring the following aspects of participant relationships with community dogs: (1) Spay/neuter clinics; (2) Role of the dog (past and present); (3) Human-animal bond; and (4) Healthy dogs as a part of healthy communities. These videos document changes in dog husbandry behaviour, new acceptance of spay/neuter, three-way knowledge transfer between residents, researchers, and policy makers, and an overall desire to sustain the positive outcomes of the pilot dog management project. This work highlights cultural beliefs and success strategies that might guide other programs providing veterinary services in First Nations communities.
A Conceptual Architecture for National Biosurveillance: Moving Beyond Situational Awareness to Enable Digital Detection of Emerging Threats
Velsko, Stephan; Bates, Thomas
Despite numerous calls for improvement, the U.S. biosurveillance enterprise remains a patchwork of uncoordinated systems that fail to take advantage of the rapid progress in information processing, communication, and analytics made in the past decade. By synthesizing components from the extensive biosurveillance literature, we propose a conceptual framework for a national biosurveillance architecture and provide suggestions for implementation. The framework differs from the current federal biosurveillance development pathway in that it is not focused on systems useful for “situational awareness,� but is instead focused on the long-term goal of having true warning capabilities. Therefore, a guiding design objective is themore » ability to digitally detect emerging threats that span jurisdictional boundaries, because attempting to solve the most challenging biosurveillance problem first provides the strongest foundation to meet simpler surveillance objectives. Core components of the vision are: (1) a whole-of-government approach to support currently disparate federal surveillance efforts that have a common data need, including those for food safety, vaccine and medical product safety, and infectious disease surveillance; (2) an information architecture that enables secure, national access to electronic health records, yet does not require that data be sent to a centralized location for surveillance analysis; (3) an inference architecture that leverages advances in ‘big data’ analytics and learning inference engines—a significant departure from the statistical process control paradigm that underpins nearly all current syndromic surveillance systems; and, (4) an organizational architecture with a governance model aimed at establishing national biosurveillance as a critical part of the U.S. national infrastructure. Although it will take many years to implement, and a national campaign of education and debate to acquire public buy-in for such a comprehensive

Core components of the vision are: (1) a whole-of-government approach to support currently disparate federal surveillance efforts that have a common data need, including those for food safety, vaccine and medical product safety, and infectious disease surveillance; (2) an information architecture that enables secure national access to electronic health records, yet does not require that data be sent to a centralized location for surveillance analysis; (3) an inference architecture that leverages advances in "big data" analytics and learning inference engines-a significant departure from the statistical process control paradigm that underpins nearly all current syndromic surveillance systems; and (4) an organizational architecture with a governance model aimed at establishing national biosurveillance as a critical part of the US national infrastructure. Although it will take many years to implement, and a national campaign of education and debate to acquire public buy-in for such a comprehensive system, the potential
Identifying the relevant features of the National Digital Cadastral Database (NDCDB) for spatial analysis by using the Delphi Technique
Halim, N. Z. A.; Sulaiman, S. A.; Talib, K.; Ng, E. G.
This paper explains the process carried out in identifying the relevant features of the National Digital Cadastral Database (NDCDB) for spatial analysis. The research was initially a part of a larger research exercise to identify the significance of NDCDB from the legal, technical, role and land-based analysis perspectives. The research methodology of applying the Delphi technique is substantially discussed in this paper. A heterogeneous panel of 14 experts was created to determine the importance of NDCDB from the technical relevance standpoint. Three statements describing the relevant features of NDCDB for spatial analysis were established after three rounds of consensus building. It highlighted the NDCDB’s characteristics such as its spatial accuracy, functions, and criteria as a facilitating tool for spatial analysis. By recognising the relevant features of NDCDB for spatial analysis in this study, practical application of NDCDB for various analysis and purpose can be widely implemented.
Seismic Tomography.
Anderson, Don L.; Dziewonski, Adam M.
Describes how seismic tomography is used to analyze the waves produced by earthquakes. The information obtained from the procedure can then be used to map the earth's mantle in three dimensions. The resulting maps are then studied to determine such information as the convective flow that propels the crustal plates. (JN)

Digit ratio (2D:4D) and gender inequalities across nations.
Manning, John T; Fink, Bernhard; Trivers, Robert
Gender inequality varies across nations, where such inequality is defined as the disproportionate representation of one sex over the other in desirable social, economic, and biological roles (typically male over female). Thus in Norway, 40% of parliamentarians are women, in the USA 17%, and in Saudi Arabia 0%. Some of this variation is associated with economic prosperity but there is evidence that this cause and effect can go in either direction. Here we show that within a population the average ratio of index (2D) to ring (4D) finger lengths (2D:4D)-a proxy measure of the relative degree to which offspring is exposed in utero to testosterone versus estrogen-is correlated with measures of gender inequality between nations. We compared male and female 2D:4D ratios to female parliamentary representation, labor force participation, female education level, maternal mortality rates, and juvenile pregnancy rates per nation in a sample of 29 countries. We found those nations who showed higher than expected female fetal exposure to testosterone (low 2D:4D) and lower than expected male exposure to fetal testosterone (high 2D:4D) had higher rates of female parliamentary representation, and higher female labor force participation. In short, the more similar the two sexes were in 2D:4D, the more equal were the two sexes in parliamentary and labor force participation. The other variables were not as strongly correlated. We suggest that higher than expected fetal testosterone in females and lower fetal testosterone in males may lead to high female representation in the national labor force and in parliament.
Analysis of the seismicity in the region of Mirovo salt mine after 8 years monitoring
Dimitrova, Liliya; Solakov, Dimcho; Simeonova, Stela; Aleksandrova, Irena; Georgieva, Gergana
Mirovo salt deposit is situated in the NE part of Bulgaria and 5 kilometers away from the town of Provadiya. The mine is in operation since 1956. The salt is produced by dilution and extraction of the brine to the surface. A system of chambers-pillars is formed within the salt body as a result of the applied technology. The mine is situated in a seismically quiet part of the state. The region is characterized with complex geological structure and several faults. During the last 3 decades a large number of small and moderate earthquakes (M<4.5) are realized in the close vicinity of the salt deposit. Local seismological network (LSN) is deployed in the region to monitor the local seismicity. It consists of 6 three component digital stations. A real-time data transfer from LSN stations to National Data Center (in Sofia) is implemented using the VPN and MAN networks of the Bulgarian Telecommunication Company. Common processing and interpretation of the data from LSN and the national seismic network is performed. Real-time and interactive data processing are performed by the Seismic Network Data Processor (SNDP) software package. More than 700 earthquakes are registered by the LSN within 30km region around the mine during the 8 years monitoring. First we processed the data and compile a catalogue of the earthquakes occur within the studied region (30km around the salt mine). Spatial pattern of seismicity is analyzed. A large number of the seismic events occurred within the northern and north-western part of the salt body. Several earthquakes occurred in close vicinity of the mine. Concerning that the earthquakes could be tectonic and/or induced an attempt is made to find criteria to distinguish natural from induced seismicity. To characterize and distinguish the main processes active in the area we also made waveform and spectral analysis of a number of earthquakes.
Your fate is in your hands? Handedness, digit ratio (2D:4D), and selection to a national talent development system.
Baker, Joseph; Kungl, Ann-Marie; Pabst, Jan; Strauß, Bernd; Büsch, Dirk; Schorer, Jörg
Over the past decade a small evidence base has highlighted the potential importance of seemingly innocuous variables related to one's hands, such as hand dominance and the relative length of the second and fourth digits (2D:4D ratio), to success in sport. This study compared 2D:4D digit ratio and handedness among handball players selected to advance in a national talent development system with those not selected. Participants included 480 youth handball players (240 females and 240 males) being considered as part of the talent selection programme for the German Youth National team. Hand dominance and digit ratio were compared to age-matched control data using standard t-tests. There was a greater proportion of left-handers compared to the normal population in males but not in females. There was also a lower digit ratio in both females and males. However, there were no differences between those selected for the next stage of talent development and those not selected on either handedness or digit ratio. These results add support for general effects for both digit ratio and handedness in elite handball; however, these factors seem inadequate to explain talent selection decisions at this level.
Hospital information systems: experience at the fully digitized Seoul National University Bundang Hospital.
Yoo, Sooyoung; Hwang, Hee; Jheon, Sanghoon
The different levels of health information technology (IT) adoption and its integration into hospital workflow can affect the maximization of the benefits of using of health IT. We aimed at sharing our experiences and the journey to the successful adoption of health IT over 13 years at a tertiary university hospital in South Korea. The integrated system of comprehensive applications for direct care, support care, and smart care has been implemented with the latest IT and a rich user information platform, achieving the fully digitized hospital. The users experience design methodology, barcode and radio-frequency identification (RFID) technologies, smartphone and mobile technologies, and data analytics were integrated into hospital workflow. Applications for user-centered electronic medical record (EMR) and clinical decision support (CDS), closed loop medication administration (CLMA), mobile EMR and dashboard system for care coordination, clinical data warehouse (CDW) system, and patient engagement solutions were designed and developed to improve quality of care, work efficiency, and patient safety. We believe that comprehensive electronic health record systems and patient-centered smart hospital applications will go a long way in ensuring seamless patient care and experience.
Historical Seismicity of Central Panama
Camacho, E.
Central Panama lies in the Panama microplate, neighboring seismically active regions of Costa Rica and Colombia. This region, crossed by the Panama Canal, concentrates most of the population and economic activity of the Republic of Panama. Instrumental observation of earthquakes in Panama began on 1882 by the Compagnie Universelle du Canal Interocéanique de Panama and continued from 1904 to 1977 by the Panama Canal Company. From October 1997 to March 1998 the USGS deployed a temporary digital seismic network. Since 2003 this region is monitored by a digital seismic network operated by the Panama Canal Authority and I complemented by the broad band stations of the University of Panama seismic network. The seismicity in this region is very diffuse and the few events which are recorded have magnitudes less than 3.0. Historical archives and antique newspapers from Spain, Colombia, Panama and the United Sates have been searched looking for historical earthquake information which could provide a better estimate of the seismicity in this region. We find that Panama City has been shaken by two destructive earthquakes in historical times. One by a local fault (i.e. Pedro Miguel fault) on May 2, 1621 (I=Vlll MM), and a subduction event from the North Panama Deformed Belt (NPDB) on September 7, 1882 (I=Vll MM). To test these findings two earthquakes scenarios were generated, using SELENA, for Panama City Old Quarter. Panama City was rebuilt on January 21, 1673, on a rocky point facing the Pacific Ocean after the sack by pirate Morgan on January 28, 1671. The pattern of damage to calicanto (unreinforced colonial masonry) and wood structures for a crustal local event are higher than those for an event from the NPDB and seem to confirm that the city has not been shaken by a major local event since May 2, 1621 and a subduction event since September 7, 1882
Deploying digital health data to optimize influenza surveillance at national and local scales
Arab, Ali; Viboud, Cécile; Grenfell, Bryan T.; Bansal, Shweta
The surveillance of influenza activity is critical to early detection of epidemics and pandemics and the design of disease control strategies. Case reporting through a voluntary network of sentinel physicians is a commonly used method of passive surveillance for monitoring rates of influenza-like illness (ILI) worldwide. Despite its ubiquity, little attention has been given to the processes underlying the observation, collection, and spatial aggregation of sentinel surveillance data, and its subsequent effects on epidemiological understanding. We harnessed the high specificity of diagnosis codes in medical claims from a database that represented 2.5 billion visits from upwards of 120,000 United States healthcare providers each year. Among influenza seasons from 2002-2009 and the 2009 pandemic, we simulated limitations of sentinel surveillance systems such as low coverage and coarse spatial resolution, and performed Bayesian inference to probe the robustness of ecological inference and spatial prediction of disease burden. Our models suggest that a number of socio-environmental factors, in addition to local population interactions, state-specific health policies, as well as sampling effort may be responsible for the spatial patterns in U.S. sentinel ILI surveillance. In addition, we find that biases related to spatial aggregation were accentuated among areas with more heterogeneous disease risk, and sentinel systems designed with fixed reporting locations across seasons provided robust inference and prediction. With the growing availability of health-associated big data worldwide, our results suggest mechanisms for optimizing digital data streams to complement traditional surveillance in developed settings and enhance surveillance opportunities in developing countries.

Chua, Michael E; Lapitan, Marie Carmela M; Morales, Marcelino L; Roque, Aristotle Bernard Maniego; Domingo, John Kenneth
"Mag-paDRE" is a yearly prostate health public awareness program initiated by the Philippine Urological Association. This study aimed to describe the demographic and clinical data of the participants in the 2013 "Mag-paDRE" program and to identify factors that will further improve prostate health public awareness. A descriptive cross-sectional study undertaken to collect and assess the demographic data, International Prostate Symptom Score (IPSS) and digital rectal examination findings of the participants in the "Mag-paDRE" conducted in the 10 Philippine Board of Urology (PBU) different accredited training institutions. Descriptive statistics was used to report the proportion of Filipino men aged 40 or older who presented for their first prostate health evaluation. Clinical profile were reviewed and summarized. The study protocol was registered in the Clinicaltrial.gov under Identifier NCT01886547. A total of 925 participants from the 10 PBU accredited training institutions were assessed. Among the 10 training institutions the large tertiary government owned medical center had the highest number of participants and target participants recruited; while the private sectors owned tertiary hospitals have the highest proportion of target participants and cases. According to the predetermined definition of this study, 614 (66%) were considered the target population for the "Mag-paDRE" program. The mean age of the target participants was 58.9±9.9. Only 360 of 614 (59%) were new case, 118 (32.7%) had severe lower urinary tract symptoms (LUTS), 223 (62%) had moderate LUTS, 19 (5.3%) were asymptomatic but with hard prostates, palpable prostate nodules or prostate tenderness. The most bothersome symptoms were incomplete bladder emptying (30.2%), and frequency (22.9%). Overall, the 2013 "Mag-paDRE" among the 10 training institutions was effective in promoting prostate health awareness. A need to modify the preactivity information dissemination by these institutions can be

Archive of Digital Boomer Seismic Reflection Data Collected During USGS Field Activities 93LCA01 and 94LCA01 in Kingsley, Orange, and Lowry Lakes, Northeast Florida, 1993 and 1994
Calderon, Karynna; Dadisman, Shawn V.; Kindinger, Jack G.; Davis, Jeffrey B.; Flocks, James G.; Wiese, Dana S.
In August and September of 1993 and January of 1994, the U.S. Geological Survey, under a cooperative agreement with the St. Johns River Water Management District (SJRWMD), conducted geophysical surveys of Kingsley Lake, Orange Lake, and Lowry Lake in northeast Florida. This report serves as an archive of unprocessed digital boomer seismic reflection data, trackline maps, navigation files, GIS information, observer's logbook, Field Activity Collection System (FACS) logs, and formal FGDC metadata. A filtered and gained GIF image of each seismic profile is also provided. Refer to the Acronyms page for expansion of acronyms and abbreviations used in this report. The archived trace data are in standard Society of Exploration Geophysicists (SEG) SEG-Y format (Barry and others, 1975) and may be downloaded and processed with commercial or public domain software such as Seismic Unix (SU). Examples of SU processing scripts and in-house (USGS) software for viewing SEG-Y files (Zihlman, 1992) are also provided. The data archived here were collected under a cooperative agreement with the St. Johns River Water Management District as part of the USGS Lakes and Coastal Aquifers (LCA) Project. For further information about this study, refer to http://coastal.er.usgs.gov/stjohns, Kindinger and others (1994), and Kindinger and others (2000). The USGS Florida Integrated Science Center (FISC) - Coastal and Watershed Studies in St. Petersburg, Florida, assigns a unique identifier to each cruise or field activity. For example, 93LCA01 tells us the data were collected in 1993 for the Lakes and Coastal Aquifers (LCA) Project and the data were collected during the first field activity for that project in that calendar year. For a detailed description of the method used to assign the field activity ID, see http://walrus.wr.usgs.gov/infobank/programs/html/definition/activity.html.

Travel times of P and S from the global digital seismic networks: Implications for the relative variation of P and S velocity in the mantle
Bolton, H.; Masters, G.
We present new data sets of P and S arrival times which have been handpicked from long-period vertical and transverse component recordings of the various global seismic networks. Using events which occurred from 1976 to 1994 results in ???38,000 globally well-distributed measurements of teleseismic P and ???41,000 measurements of S. These data are particularly useful for looking at the relative variation of S and P velocities in the lower mantle. We describe both the measurement techniques and the gross characteristics of the data sets. The size of our data sets allows us to exploit the internal consistency of the data to identify outliers using a summary ray analysis. Since the polarity of each arrival is also known, we can construct fault plane solutions and J.or compare with polarities predicted by the Harvard centroid moment tensor solutions to further diagnose phase misidentification. This analysis results in ???5% of the data being identified as outliers. An analysis of variance indicates that the S residual travel times are dominated by the effects of three-dimensional structure but the P data have comparable contributions from noise and source mislocation effects. The summary ray analysis reveals the basic character of lower mantle structure, and there are large-scale patterns in both the S and P data sets that correlate quite well with each other. This analysis suggests that on average, d ln vS J.d. In vP is an increasing function of depth in the mantle going from a value of ???1.7 at the top of the lower mantle to an apparent value of 4 near the base of the mantle. This latter extreme value of R seems to result mainly from data which sample one region in the lowermost mantle under the central Pacific, where large positive S residuals are associated with very small P residuals. Such an anomaly cannot be thermal in origin. Copyright 2001 by the American Geophysical Union.
A filter circuit board for the Earthworm Seismic Data Acquisition System
Jensen, Edward Gray
The Earthworm system is a seismic network data acquisition and processing system used by the Northern California Seismic Network as well as many other seismic networks. The input to the system is comprised of many realtime electronic waveforms fed to a multi-channel digitizer on a PC platform. The digitizer consists of one or more National Instruments Corp. AMUX–64T multiplexer boards attached to an A/D converter board located in the computer. Originally, passive filters were installed on the multiplexers to eliminate electronic noise picked up in cabling. It was later discovered that a small amount of crosstalk occurred between successive channels in the digitizing sequence. Though small, this crosstalk will cause what appear to be small earthquake arrivals at the wrong time on some channels. This can result in erroneous calculation of earthquake arrival times, particularly by automated algorithms. To deal with this problem, an Earthworm filter board was developed to provide the needed filtering while eliminating crosstalk. This report describes the tests performed to find a suitable solution, and the design of the circuit board. Also included are all the details needed to build and install this board in an Earthworm system or any other system using the AMUX–64T board. Available below is the report in PDF format as well as an archive file containing the circuit board manufacturing information.
Structural Geology of the Northwestern Portion of Los Alamos National Laboratory, Rio Grande Rift, New Mexico: Implications for Seismic Surface Rupture Potential from TA-3 to TA-55
Jamie N. Gardner: Alexis Lavine; Giday WoldeGabriel; Donathon Krier
Los Alamos National Laboratory lies at the western boundary of the Rio Grande rift, a major tectonic feature of the North American Continent. Three major faults locally constitute the modem rift boundary, and each of these is potentially seismogenic. In this study we have gathered structural geologic data for the northwestern portion of Los Alamos National Laboratory through high-precision geologic mapping, conventional geologic mapping, stratigraphic studies, drilling, petrologic studies, and stereographic aerial photograph analyses. Our study area encompasses TA-55 and TA-3, where potential for seismic surface rupture is of interest, and is bounded on the north and south by themore » townsite of Los Alamos and Twomile Canyon, respectively. The study area includes parts of two of the potentially active rift boundary faults--the Pajarito and Rendija Canyon faults-that form a large graben that we name the Diamond Drive graben. The graben embraces the western part of the townsite of Los Alamos, and its southern end is in the TA-3 area where it is defined by east-southeast-trending cross faults. The cross faults are small, but they accommodate interactions between the two major fault zones and gentle tilting of structural blocks to the north into the graben. North of Los Alamos townsite, the Rendija Canyon fault is a large normal fault with about 120 feet of down-to-the-west displacement over the last 1.22 million years. South from Los Alamos townsite, the Rendija Canyon fault splays to the southwest into a broad zone of deformation. The zone of deformation is about 2,000 feet wide where it crosses Los Alamos Canyon and cuts through the Los Alamos County Landfill. Farther southwest, the fault zone is about 3,000 feet wide at the southeastern corner of TA-3 in upper Mortandad Canyon and about 5,000 feet wide in Twomile Canyon. Net down-to-the-west displacement across the entire fault zone over the last 1.22 million years decreases to the south as the fault zone
National electronic health records and the digital disruption of moral orders.
Garrety, Karin; McLoughlin, Ian; Wilson, Rob; Zelle, Gregor; Martin, Mike
The digitalisation of patient health data to provide national electronic health record systems (NEHRS) is a major objective of many governments. Proponents claim that NEHRS will streamline care, reduce mistakes and cut costs. However, building these systems has proved highly problematic. Using recent developments in Australia as an example, we argue that a hitherto unexamined source of difficulty concerns the way NEHRS disrupt the moral orders governing the production, ownership, use of and responsibility for health records. Policies that pursue digitalisation as a self-evident 'solution' to problems in healthcare without due regard to these disruptions risk alienating key stakeholders. We propose a more emergent approach to the development and implementation of NEHRS that supports moral re-ordering around rights and responsibilities appropriate to the intentions of those involved in healthcare relationships.

Reevaluation of the Seismicity and seismic hazards of Northeastern Libya
Ben Suleman, abdunnur; Aousetta, Fawzi
Libya, located at the northern margin of the African continent, underwent many episodes of orogenic activities. These episodes of orogenic activities affected and shaped the geological setting of the country. This study represents a detailed investigation that aims to focus on the seismicity and its implications on earthquake hazards of Northeastern Libya. At the end of year 2005 the Libyan National Seismological Network starts functioning with 15 stations. The Seismicity of the area under investigation was reevaluated using data recorded by the recently established network. The Al-Maraj earthquake occurred in May 22nd 2005was analyzed. This earthquake was located in a known seismically active area. This area was the sight of the well known 1963 earthquake that kills over 200 people. Earthquakes were plotted and resulting maps were interpreted and discussed. The level of seismic activity is higher in some areas, such as the city of Al-Maraj. The offshore areas north of Al-Maraj seem to have higher seismic activity. It is highly recommended that the recent earthquake activity is considered in the seismic hazard assessments for the northeastern part of Libya.
Romanian Educational Seismic Network Project
Tataru, Dragos; Ionescu, Constantin; Zaharia, Bogdan; Grecu, Bogdan; Tibu, Speranta; Popa, Mihaela; Borleanu, Felix; Toma, Dragos; Brisan, Nicoleta; Georgescu, Emil-Sever; Dobre, Daniela; Dragomir, Claudiu-Sorin
Romania is one of the most active seismic countries in Europe, with more than 500 earthquakes occurring every year. The seismic hazard of Romania is relatively high and thus understanding the earthquake phenomena and their effects at the earth surface represents an important step toward the education of population in earthquake affected regions of the country and aims to raise the awareness about the earthquake risk and possible mitigation actions. In this direction, the first national educational project in the field of seismology has recently started in Romania: the ROmanian EDUcational SEISmic NETwork (ROEDUSEIS-NET) project. It involves four partners: the National Institute for Earth Physics as coordinator, the National Institute for Research and Development in Construction, Urban Planning and Sustainable Spatial Development " URBAN - INCERC" Bucharest, the BabeÅŸ-Bolyai University (Faculty of Environmental Sciences and Engineering) and the software firm "BETA Software". The project has many educational, scientific and social goals. The main educational objectives are: training students and teachers in the analysis and interpretation of seismological data, preparing of several comprehensive educational materials, designing and testing didactic activities using informatics and web-oriented tools. The scientific objective is to introduce into schools the use of advanced instruments and experimental methods that are usually restricted to research laboratories, with the main product being the creation of an earthquake waveform archive. Thus a large amount of such data will be used by students and teachers for educational purposes. For the social objectives, the project represents an effective instrument for informing and creating an awareness of the seismic risk, for experimentation into the efficacy of scientific communication, and for an increase in the direct involvement of schools and the general public.

Digital soil mapping as a basis for climatically oriented agriculture a thematic on the territory of the national crop testing fields of the Republic of Tatarstan, Russia
Sahabiev, I. A.; Giniyatullin, K. G.; Ryazanov, S. S.
The concept of climate-optimized agriculture (COA) of the UN FAO implies the transformation of agriculture techniques in conditions of changing climate. It is important to implement a timely transition to the concept of COA and sustainable development of soil resources, accurate digital maps of spatial distribution of soils and soil properties are needed. Digital mapping of soil humus content was carried out on the territory of the national crop testing fields (NCTF) of the Republic of Tatarstan (Russian Federation) and the accuracy of the maps obtained was estimated.
On-line Data Transmission, as Part of the Seismic Evaluation Process in the Buildings Field
Sorin Dragomir, Claudiu; Dobre, Daniela; Craifaleanu, Iolanda; Georgescu, Emil-Sever
The thorough analytical modelling of seismic actions, of the structural system and of the foundation soil is essential for a proper dynamic analysis of a building. However, the validation of the used models should be made, whenever possible, with reference to results obtained from experimental investigations, building instrumentation and monitoring of vibrations generated by various seismic or non-seismic sources. In Romania, the permanent seismic instrumentation/monitoring of buildings is part of a special follow-up activity, performed in accordance with the P130/1999 code for the time monitoring of building behaviour and with the seismic design code, P100-2013. By using the state-of-the-art modern equipment (GeoSIG and Kinemetrics digital accelerographs) in the seismic network of the National Institute for Research and Development URBAN-INCERC, the instrumented buildings can be monitored remotely, with recorded data being sent to authorities or to research institutes in the field by a real-time data transmission system. The obtained records are processed, computing the Fourier amplitude spectra and the response spectra, and the modal parameters of buildings are determined. The paper presents some of the most important results of the institute in the field of building monitoring, focusing on the situation of some significant instrumented buildings located in different parts of the country. In addition, maps with data received from seismic stations after the occurrence of two recent Vrancea (Romania) earthquakes, showing the spatial distribution of ground accelerations, are presented, together with a comparative analysis, performed with reference to previous studies in the literature.
DEVELOPMENT OF LAND COVER AND TERRAIN DATA BASES FOR THE INNOKO NATIONAL WILDLIFE REFUGE, ALASKA, USING LANDSAT AND DIGITAL TERRAIN DATA.
Markon, Carl J.; Talbot, Stephen
Landsat-derived land cover maps and associated elevation, slope, and aspect class maps were produced for the Innoko National Wildlife Refuge (3,850,000 acres; 1,555,095 hectares) in northwestern Alaska. These maps and associated digital data products are being used by the U. S. Fish and Wildlife Service for wildlife management, research, and comprehensive conservation planning. Portions of two Landsat Multispectral Scanner (MSS) scenes and digital terrain data were used to produce 1:250,000 scale land cover and terrain maps. Prints of summer and winter Landsat MSS scenes were used to manually interpret broad physiographic strata. These strata were transferred to U. S. Geological Survey 1:250,000-scale topographic maps and digitized. Seven major land cover classes and 23 subclasses were identified. The major land cover classes include: forest, scrub, dwarf scrub and related types, herbaceous, scarcely vegetated areas, water, and shadow.
Historical seismicity
Dengler, L.
The North Coast region of California in the vicinity of Cape Mendocino is one of the state's most seismically active areas, accounting for 25 percent of seismic energy release in California during the last 50 years. the region is located in a geologically dynamic are surrounding the Mendocino triple junction where three of the Earth's tectonic plates join together ( see preceding article by Sam Clarke). In the historic past the North Coast has been affected by earthquakes occurring on the San Andreas fault system to the south, the Mendocino fault to the southwest, and intraplate earthquakes within both the Gorda and North American plates. More than sixty of these earthquakes have caused damage since the mid-1800's. Recent studies indicate that California's North Coast is also at risk with respect to very large earthquakes (magnitude >8) originating along the Cascadia subduction zone. Although the subduction zone has not generated great earthquakes in historic time, paleoseismic evidence suggests that such earthquakes have been generated by the subduction zone in the recent prehistoric past.Â
Summary of November 2010 meeting to evaluate turbidite data for constraining the recurrence parameters of great Cascadia earthquakes for the update of national seismic hazard maps
Frankel, Arthur D.
This report summarizes a meeting of geologists, marine sedimentologists, geophysicists, and seismologists that was held on November 18–19, 2010 at Oregon State University in Corvallis, Oregon. The overall goal of the meeting was to evaluate observations of turbidite deposits to provide constraints on the recurrence time and rupture extent of great Cascadia subduction zone (CSZ) earthquakes for the next update of the U.S. national seismic hazard maps (NSHM). The meeting was convened at Oregon State University because this is the major center for collecting and evaluating turbidite evidence of great Cascadia earthquakes by Chris Goldfinger and his colleagues. We especially wanted the participants to see some of the numerous deep sea cores this group has collected that contain the turbidite deposits. Great earthquakes on the CSZ pose a major tsunami, ground-shaking, and ground-failure hazard to the Pacific Northwest. Figure 1 shows a map of the Pacific Northwest with a model for the rupture zone of a moment magnitude Mw 9.0 earthquake on the CSZ and the ground shaking intensity (in ShakeMap format) expected from such an earthquake, based on empirical ground-motion prediction equations. The damaging effects of such an earthquake would occur over a wide swath of the Pacific Northwest and an accompanying tsunami would likely cause devastation along the Pacifc Northwest coast and possibly cause damage and loss of life in other areas of the Pacific. A magnitude 8 earthquake on the CSZ would cause damaging ground shaking and ground failure over a substantial area and could also generate a destructive tsunami. The recent tragic occurrence of the 2011 Mw 9.0 Tohoku-Oki, Japan, earthquake highlights the importance of having accurate estimates of the recurrence times and magnitudes of great earthquakes on subduction zones. For the U.S. national seismic hazard maps, estimating the hazard from the Cascadia subduction zone has been based on coastal paleoseismic evidence of great
Adding seismic broadband analysis to characterize Andean backarc seismicity in Argentina
Alvarado, P.; Giuliano, A.; Beck, S.; Zandt, G.
Characterization of the highly seismically active Andean backarc is crucial for assessment of earthquake hazards in western Argentina. Moderate-to-large crustal earthquakes have caused several deaths, damage and drastic economic consequences in Argentinean history. We have studied the Andean backarc crust between 30°S and 36°S using seismic broadband data available from a previous ("the CHARGE") IRIS-PASSCAL experiment. We collected more than 12 terabytes of continuous seismic data from 22 broadband instruments deployed across Chile and Argentina during 1.5 years. Using free software we modeled full regional broadband waveforms and obtained seismic moment tensor inversions of crustal earthquakes testing for the best focal depth for each event. We also mapped differences in the Andean backarc crustal structure and found a clear correlation with different types of crustal seismicity (i.e. focal depths, focal mechanisms, magnitudes and frequencies of occurrence) and previously mapped terrane boundaries. We now plan to use the same methodology to study other regions in Argentina using near-real time broadband data available from the national seismic (INPRES) network and global seismic networks operating in the region. We will re-design the national seismic network to optimize short-period and broadband seismic station coverage for different network purposes. This work is an international effort that involves researchers and students from universities and national government agencies with the goal of providing more information about earthquake hazards in western Argentina.
Digitization, Integration and Preservation of Technical and Historical Information: The Case of INTA, the National Institute for Aerospace Technique of Spain
Merida MartÃn, F.; Paz Otero, S.
During the last two years the INTA -- National Institute for Aerospace Technique -- library has been improving different areas related to the information management processes, such as those related to cataloguing, dissemination of technical information, centralization at the Library of all relevant documents and information applicable to scientific research within our organization, implementation of library web services, etc. As part of these processes of modernization of services that the INTA Library is carrying out, a project of digitization of both technical documentation and historical records of the Institute has been defined. The goal is to achieve the total digitization of technical documents and historical papers through the year 2006, and provide access for the resulting electronic collection to the Spanish aerospace community. For the development of the project a deep study of the state of the art in digitization and preservation matters has been conducted. That study covers the different aspects of such a project that could be experienced, such as the risk of data loss, the bandwidth needed to guarantee access to this huge quantity of electronic documentation, the fragility of the digital media, the rapid obsolescence of hardware and software, etc. Also the project is going to assume the new reality of documents that are not originating in paper format, but are digital-born, and how to integrate all the electronic documents in one system, fulfilling the same standards and using the same available technology.
Southern Appalachian Regional Seismic Network
Chiu, S.C.C.; Johnston, A.C.; Chiu, J.M.
The seismic activity in the southern Appalachian area was monitored by the Southern Appalachian Regional Seismic Network (SARSN) since late 1979 by the Center for Earthquake Research and Information (CERI) at Memphis State University. This network provides good spatial coverage for earthquake locations especially in east Tennessee. The level of activity concentrates more heavily in the Valley and Ridge province of eastern Tennessee, as opposed to the Blue Ridge or Inner Piedmont. The large majority of these events lie between New York - Alabama lineament and the Clingman/Ocoee lineament, magnetic anomalies produced by deep-seated basement structures. Therefore SARSN, even withmore » its wide station spacing, has been able to define the essential first-order seismological characteristics of the Southern Appalachian seismic zone. The focal depths of the southeastern U.S. earthquakes concentrate between 8 and 16 km, occurring principally beneath the Appalachian overthrust. In cross-sectional views, the average seismicity is shallower to the east beneath the Blue Ridge and Piedmont provinces and deeper to the west beneath the Valley and Ridge and the North American craton. Results of recent focal mechanism studies by using the CERI digital earthquake catalog between October, 1986 and December, 1991, indicate that the basement of the Valley and Ridge province is under a horizontal, NE-SW compressive stress. Right-lateral strike-slip faulting on nearly north-south fault planes is preferred because it agrees with the trend of the regional magnetic anomaly pattern.« less
Seismic Monitoring for the United Arab Emirates
Rodgers, A; Nakanishi, K
There is potential for earthquakes in the United Arab Emirates and in the Zagros mountains to cause structural damage and pose a threat to safety of people. Damaging effects from earthquakes can be mitigated by knowledge of the location and size of earthquakes, effects on construction, and monitoring these effects over time. Although a general idea of seismicity in the UAE may be determined with data from global seismic networks, these global networks do not have the sensitivity to record smaller seismic events and do not have the necessary accuracy to locate the events. A National Seismic Monitoring Observatory ismore » needed for the UAE that consists of a modern seismic network and a multidisciplinary staff that can analyze and interpret the data from the network. A seismic network is essential to locate earthquakes, determine event magnitudes, identify active faults and measure ground motions from earthquakes. Such a network can provide the data necessary for a reliable seismic hazard assessment in the UAE. The National Seismic Monitoring Observatory would ideally be situated at a university that would provide access to the wide range of disciplines needed in operating the network and providing expertise in analysis and interpretation.« less
LANL seismic screening method for existing buildings
Dickson, S.L.; Feller, K.C.; Fritz de la Orta, G.O.
The purpose of the Los Alamos National Laboratory (LANL) Seismic Screening Method is to provide a comprehensive, rational, and inexpensive method for evaluating the relative seismic integrity of a large building inventory using substantial life-safety as the minimum goal. The substantial life-safety goal is deemed to be satisfied if the extent of structural damage or nonstructural component damage does not pose a significant risk to human life. The screening is limited to Performance Category (PC) -0, -1, and -2 buildings and structures. Because of their higher performance objectives, PC-3 and PC-4 buildings automatically fail the LANL Seismic Screening Method andmore » will be subject to a more detailed seismic analysis. The Laboratory has also designated that PC-0, PC-1, and PC-2 unreinforced masonry bearing wall and masonry infill shear wall buildings fail the LANL Seismic Screening Method because of their historically poor seismic performance or complex behavior. These building types are also recommended for a more detailed seismic analysis. The results of the LANL Seismic Screening Method are expressed in terms of separate scores for potential configuration or physical hazards (Phase One) and calculated capacity/demand ratios (Phase Two). This two-phase method allows the user to quickly identify buildings that have adequate seismic characteristics and structural capacity and screen them out from further evaluation. The resulting scores also provide a ranking of those buildings found to be inadequate. Thus, buildings not passing the screening can be rationally prioritized for further evaluation. For the purpose of complying with Executive Order 12941, the buildings failing the LANL Seismic Screening Method are deemed to have seismic deficiencies, and cost estimates for mitigation must be prepared. Mitigation techniques and cost-estimate guidelines are not included in the LANL Seismic Screening Method.« less
Seismic sources
Green, M.A.; Cook, N.G.W.; McEvilly, T.V.; Majer, E.L.; Witherspoon, P.A.
Apparatus is described for placement in a borehole in the earth, which enables the generation of closely controlled seismic waves from the borehole. Pure torsional shear waves are generated by an apparatus which includes a stator element fixed to the borehole walls and a rotor element which is electrically driven to rapidly oscillate on the stator element to cause reaction forces transmitted through the borehole walls to the surrounding earth. Longitudinal shear waves are generated by an armature that is driven to rapidly oscillate along the axis of the borehole, to cause reaction forces transmitted to the surrounding earth. Pressure waves are generated by electrically driving pistons that press against opposite ends of a hydraulic reservoir that fills the borehole. High power is generated by energizing the elements for more than about one minute. 9 figs.
Mapping polar bear maternal denning habitat in the National Petroleum Reserve -- Alaska with an IfSAR digital terrain model
Durner, George M.; Simac, Kristin S.; Amstrup, Steven C.
The National Petroleum Reserve–Alaska (NPR-A) in northeastern Alaska provides winter maternal denning habitat for polar bears (Ursus maritimus) and also has high potential for recoverable hydrocarbons. Denning polar bears exposed to human activities may abandon their dens before their young are able to survive the severity of Arctic winter weather. To ensure that wintertime petroleum activities do not threaten polar bears, managers need to know the distribution of landscape features in which maternal dens are likely to occur. Here, we present a map of potential denning habitat within the NPR-A. We used a fine-grain digital elevation model derived from Interferometric Synthetic Aperture Radar (IfSAR) to generate a map of putative denning habitat. We then tested the map’s ability to identify polar bear denning habitat on the landscape. Our final map correctly identified 82% of denning habitat estimated to be within the NPR-A. Mapped denning habitat comprised 19.7 km2 (0.1% of the study area) and was widely dispersed. Though mapping denning habitat with IfSAR data was as effective as mapping with the photogrammetric methods used for other regions of the Alaskan Arctic coastal plain, the use of GIS to analyze IfSAR data allowed greater objectivity and flexibility with less manual labor. Analytical advantages and performance equivalent to that of manual cartographic methods suggest that the use of IfSAR data to identify polar bear maternal denning habitat is a better management tool in the NPR-A and wherever such data may be available.
Predictors of eHealth usage: insights on the digital divide from the Health Information National Trends Survey 2012.
Kontos, Emily; Blake, Kelly D; Chou, Wen-Ying Sylvia; Prestin, Abby
Recent eHealth developments have elevated the importance of assessing the extent to which technology has empowered patients and improved health, particularly among the most vulnerable populations. With noted disparities across racial and social groups in chronic health outcomes, such as cancer, obesity, and diabetes, it is essential that researchers examine any differences in the implementation, uptake, and impact of eHealth strategies across groups that bear a disproportionate burden of disease. The goal was to examine eHealth use by sociodemographic factors, such as race/ethnicity, socioeconomic status (SES), age, and sex. We drew data from National Cancer Institute's 2012 Health Information National Trends Survey (HINTS) (N=3959) which is publicly available online. We estimated multivariable logistic regression models to assess sociodemographic predictors of eHealth use among adult Internet users (N=2358) across 3 health communication domains (health care, health information-seeking, and user-generated content/sharing). Among online adults, we saw no evidence of a digital use divide by race/ethnicity. However, there were significant differences in use by SES, particularly for health care and health information-seeking items. Patients with lower levels of education had significantly lower odds of going online to look for a health care provider (high school or less: OR 0.50, 95% CI 0.33-0.76) using email or the Internet to communicate with a doctor (high school or less: OR 0.46, 95% CI 0.29-0.72), tracking their personal health information online (high school or less: OR 0.53, 95% CI 0.32-0.84), using a website to help track diet, weight, and physical activity (high school or less: OR 0.64, 95% CI 0.42-0.98; some college: OR 0.67, 95% CI 0.49-0.93), or downloading health information to a mobile device (some college: OR 0.54, 95% CI 0.33-0.89). Being female was a consistent predictor of eHealth use across health care and user-generated content/sharing domains
Seismicity, arrival time delays of the seismic phases and slowness characteristics study in Abu Dabbab area, Egypt
Sami, Mahmoud; Hassoup, Awad; Hosny, Ahmed; Mohamed, Gadelkarem A.
The temporal variations of seismicity from the Abu Dabbab area, 25 km west of the Red Sea coast, are collected from the Egyptian national seismic network (ENSN), which has magnified the detection capability in that area to ML < 1 earthquakes. These data show a sequence of the micro earthquake swarm during 2003-2011. This area has experienced larger shocks up to M = 6 during the 20th century and its seismicity is concentrated in a narrow spatial volume. We analyze the digital waveform data of about 1000 seismograms, recorded by portable network of 10 vertical component seismographs that are employed in a temporary survey experiment in the Abu Dabbab area in 2004, and the results indicate: firstly, there are similar waveform seismograms, which are classified into three groups. In each group a master event is identified. Then, the arrival time delays of the P and S phases (Δtp and Δts, respectively) are measured between the master event and its slave events. Δtp and Δts range between -0.01 and 0.02 s, respectively. These values are used to relocate the studied events. Secondly, the slowness vector (Δs) in 3-dimensional pattern, which is estimated using the genetic algorithms, is found Δsx = 0.0153, Δsy = 0.00093 and Δsz = 0.2086 s/km in the three spatial coordinates (X, Y and Z), respectively. These analyses demonstrate the inhomogeneities within the upper crust of the study area. Also, Δs shows little dependence of lateral distances and reasonably high slowness along the depth extent, which is consistent with the seismic velocity structure variations.
P-Cable: New High-Resolution 3D Seismic Acquisition Technology
Planke, Sverre; Berndt, Christian; Mienert, Jürgen; Bünz, Stefan; Eriksen, Frode N.; Eriksen, Ola K.
We have developed a new cost-efficient technology for acquisition of high-resolution 3D seismic data: the P-Cable system. This technology is very well suited for deep water exploration, site surveys, and studies of shallow gas and fluid migration associated with gas hydrates or leaking reservoirs. It delivers unparalleled 3D seismic images of subsurface sediment architectures. The P-Cable system consists of a seismic cable towed perpendicular to a vessel's steaming direction. This configuration allows us to image an up to 150 m wide swath of the sub-surface for each sail line. Conventional 3D seismic technology relies on several very long streamers (up to 10 km long streamers are common), large sources, and costly operations. In contrast, the P-Cable system is light-weight and fast to deploy from small vessels. Only a small source is required as the system is made for relatively shallow imaging, typically above the first water-bottom multiple. The P-Cable system is particularly useful for acquisition of small 3D cubes, 10-50 km2, in focus areas, rather than extensive mapping of large regions. The rapid deployment and recovery of the system makes it possible to acquire several small cubes (10 to 30 km2) with high-resolution (50-250 Hz) seismic data in during one cruise. The first development of the P-Cable system was a cooperative project achieved by Volcanic Basin Petroleum Research (VBPR), University of Tromsø, National Oceanography Centre, Southampton, and industry partners. Field trials using a 12-streamer system were conducted on sites with active fluid-leakage systems on the Norwegian-Barents-Svalbard margin, the Gulf of Cadiz, and the Mediterranean. The second phase of the development introduced digital streamers. The new P-Cable2 system also includes integrated tow and cross cables for power and data transmission and improved doors to spread the larger cross cable. This digital system has been successfully used during six cruises by the University of Troms
High-resolution digital elevation dataset for Crater Lake National Park and vicinity, Oregon, based on LiDAR survey of August-September 2010 and bathymetric survey of July 2000
Robinson, Joel E.
Crater Lake partially fills the caldera that formed approximately 7,700 years ago during the eruption of a 12,000-foot volcano known as Mount Mazama. The caldera-forming or climactic eruption of Mount Mazama devastated the surrounding landscape, left a thick deposit of pumice and ash in adjacent valleys, and spread a blanket of volcanic ash as far away as southern Canada. Because the Crater Lake region is potentially volcanically active, knowledge of past events is important to understanding hazards from future eruptions. Similarly, because the area is seismically active, documenting and evaluating geologic faults is critical to assessing hazards from earthquakes. As part of the American Recovery and Reinvestment Act (ARRA) of 2009, the U.S. Geological Survey was awarded funding for high-precision airborne LiDAR (Light Detection And Ranging) data collection at several volcanoes in the Cascade Range through the Oregon LiDAR Consortium, administered by the Oregon Department of Geology and Mineral Industries (DOGAMI). The Oregon LiDAR Consortium contracted with Watershed Sciences, Inc., to conduct the data collection surveys. Collaborating agencies participating with the Oregon LiDAR Consortium for data collection in the Crater Lake region include Crater Lake National Park (National Park Service) and the Federal Highway Administration. In the immediate vicinity of Crater Lake National Park, 798 square kilometers of LiDAR data were collected, providing a digital elevation dataset of the ground surface beneath forest cover with an average resolution of 1.6 laser returns/m2 and both vertical and horizontal accuracies of ±5 cm. The LiDAR data were mosaicked in this report with bathymetry of the lake floor of Crater Lake, collected in 2000 using high-resolution multibeam sonar in a collaborative effort between the U.S. Geological Survey, Crater Lake National Park, and the Center for Coastal and Ocean Mapping at the University of New Hampshire.

Seismic Characterization of EGS Reservoirs
Templeton, D. C.; Pyle, M. L.; Matzel, E.; Myers, S.; Johannesson, G.
To aid in the seismic characterization of Engineered Geothermal Systems (EGS), we enhance the traditional microearthquake detection and location methodologies at two EGS systems. We apply the Matched Field Processing (MFP) seismic imaging technique to detect new seismic events using known discrete microearthquake sources. Events identified using MFP are typically smaller magnitude events or events that occur within the coda of a larger event. Additionally, we apply a Bayesian multiple-event seismic location algorithm, called MicroBayesLoc, to estimate the 95% probability ellipsoids for events with high signal-to-noise ratios (SNR). Such probability ellipsoid information can provide evidence for determining if a seismic lineation could be real or simply within the anticipated error range. We apply this methodology to the Basel EGS data set and compare it to another EGS dataset. This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
Transition from film to digital mammography: impact for breast cancer screening through the national breast and cervical cancer early detection program.
van Ravesteyn, Nicolien T; van Lier, Lisanne; Schechter, Clyde B; Ekwueme, Donatus U; Royalty, Janet; Miller, Jacqueline W; Near, Aimee M; Cronin, Kathleen A; Heijnsdijk, Eveline A M; Mandelblatt, Jeanne S; de Koning, Harry J
The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides mammograms and diagnostic services for low-income, uninsured women aged 40-64 years. Mammography facilities within the NBCCEDP gradually shifted from plain-film to digital mammography. The purpose of this study is to assess the impact of replacing film with digital mammography on health effects (deaths averted, life-years gained [LYG]); costs (for screening and diagnostics); and number of women reached. NBCCEDP 2010 data and data representative of the program's target population were used in two established microsimulation models. Models simulated observed screening behavior including different screening intervals (annual, biennial, irregular) and starting ages (40, 50 years) for white, black, and Hispanic women. Model runs were performed in 2012. The models predicted 8.0-8.3 LYG per 1,000 film screens for black women, 5.9-7.5 for white women, and 4.0-4.5 for Hispanic women. For all race/ethnicity groups, digital mammography had more LYG than film mammography (2%-4%), but had higher costs (34%-35%). Assuming a fixed budget, 25%-26% fewer women could be served, resulting in 22%-24% fewer LYG if all mammograms were converted to digital. The loss in LYG could be reversed to an 8%-13% increase by only including biennial screening. Digital could result in slightly more LYG than film mammography. However, with a fixed budget, fewer women may be served with fewer LYG. Changes in the program, such as only including biennial screening, will increase LYG/screen and could offset the potential decrease in LYG when shifting to digital mammography.

Exploring Large-Scale Cross-Correlation for Teleseismic and Regional Seismic Event Characterization
Dodge, Doug; Walter, William; Myers, Steve; Ford, Sean; Harris, Dave; Ruppert, Stan; Buttler, Dave; Hauk, Terri
The decrease in costs of both digital storage space and computation power invites new methods of seismic data processing. At Lawrence Livermore National Laboratory(LLNL) we operate a growing research database of seismic events and waveforms for nuclear explosion monitoring and other applications. Currently the LLNL database contains several million events associated with tens of millions of waveforms at thousands of stations. We are making use of this database to explore the power of seismic waveform correlation to quantify signal similarities, to discover new events not in catalogs, and to more accurately locate events and identify source types. Building on the very efficient correlation methodologies of Harris and Dodge (2011) we computed the waveform correlation for event pairs in the LLNL database in two ways. First we performed entire waveform cross-correlation over seven distinct frequency bands. The correlation coefficient exceeds 0.6 for more than 40 million waveform pairs for several hundred thousand events at more than a thousand stations. These correlations reveal clusters of mining events and aftershock sequences, which can be used to readily identify and locate events. Second we determine relative pick times by correlating signals in time windows for distinct seismic phases. These correlated picks are then used to perform very high accuracy event relocations. We are examining the percentage of events that correlate as a function of magnitude and observing station distance in selected high seismicity regions. Combining these empirical results and those using synthetic data, we are working to quantify relationships between correlation and event pair separation (in epicenter and depth) as well as mechanism differences. Our exploration of these techniques on a large seismic database is in process and we will report on our findings in more detail at the meeting.

Seismic safety in conducting large-scale blasts
Mashukov, I. V.; Chaplygin, V. V.; Domanov, V. P.; Semin, A. A.; Klimkin, M. A.
In mining enterprises to prepare hard rocks for excavation a drilling and blasting method is used. With the approach of mining operations to settlements the negative effect of large-scale blasts increases. To assess the level of seismic impact of large-scale blasts the scientific staff of Siberian State Industrial University carried out expertise for coal mines and iron ore enterprises. Determination of the magnitude of surface seismic vibrations caused by mass explosions was performed using seismic receivers, an analog-digital converter with recording on a laptop. The registration results of surface seismic vibrations during production of more than 280 large-scale blasts at 17 mining enterprises in 22 settlements are presented. The maximum velocity values of the Earth’s surface vibrations are determined. The safety evaluation of seismic effect was carried out according to the permissible value of vibration velocity. For cases with exceedance of permissible values recommendations were developed to reduce the level of seismic impact.

Active seismic experiment
Kovach, R. L.; Watkins, J. S.; Talwani, P.
The Apollo 16 active seismic experiment (ASE) was designed to generate and monitor seismic waves for the study of the lunar near-surface structure. Several seismic energy sources are used: an astronaut-activated thumper device, a mortar package that contains rocket-launched grenades, and the impulse produced by the lunar module ascent. Analysis of some seismic signals recorded by the ASE has provided data concerning the near-surface structure at the Descartes landing site. Two compressional seismic velocities have so far been recognized in the seismic data. The deployment of the ASE is described, and the significant results obtained are discussed.

Seismic hazard map of the western hemisphere
Shedlock, K.M.; Tanner, J.G.
Vulnerability to natural disasters increases with urbanization and development of associated support systems (reservoirs, power plants, etc.). Catastrophic earthquakes account for 60% of worldwide casualties associated with natural disasters. Economic damage from earthquakes is increasing, even in technologically advanced countries with some level of seismic zonation, as shown by the 1989 Loma Prieta, CA ($6 billion), 1994 Northridge, CA ($ 25 billion), and 1995 Kobe, Japan (> $ 100 billion) earthquakes. The growth of megacities in seismically active regions around the world often includes the construction of seismically unsafe buildings and infrastructures, due to an insufficient knowledge of existing seismic hazard. Minimization of the loss of life, property damage, and social and economic disruption due to earthquakes depends on reliable estimates of seismic hazard. National, state, and local governments, decision makers, engineers, planners, emergency response organizations, builders, universities, and the general public require seismic hazard estimates for land use planning, improved building design and construction (including adoption of building construction codes), emergency response preparedness plans, economic forecasts, housing and employment decisions, and many more types of risk mitigation. The seismic hazard map of the Americas is the concatenation of various national and regional maps, involving a suite of approaches. The combined maps and documentation provide a useful global seismic hazard framework and serve as a resource for any national or regional agency for further detailed studies applicable to their needs. This seismic hazard map depicts Peak Ground Acceleration (PGA) with a 10% chance of exceedance in 50 years for the western hemisphere. PGA, a short-period ground motion parameter that is proportional to force, is the most commonly mapped ground motion parameter because current building codes that include seismic provisions specify the
Predictors of eHealth Usage: Insights on The Digital Divide From the Health Information National Trends Survey 2012
Blake, Kelly D; Chou, Wen-Ying Sylvia; Prestin, Abby
Background Recent eHealth developments have elevated the importance of assessing the extent to which technology has empowered patients and improved health, particularly among the most vulnerable populations. With noted disparities across racial and social groups in chronic health outcomes, such as cancer, obesity, and diabetes, it is essential that researchers examine any differences in the implementation, uptake, and impact of eHealth strategies across groups that bear a disproportionate burden of disease. Objective The goal was to examine eHealth use by sociodemographic factors, such as race/ethnicity, socioeconomic status (SES), age, and sex. Methods We drew data from National Cancer Institute’s 2012 Health Information National Trends Survey (HINTS) (N=3959) which is publicly available online. We estimated multivariable logistic regression models to assess sociodemographic predictors of eHealth use among adult Internet users (N=2358) across 3 health communication domains (health care, health information–seeking, and user-generated content/sharing). Results Among online adults, we saw no evidence of a digital use divide by race/ethnicity. However, there were significant differences in use by SES, particularly for health care and health information–seeking items. Patients with lower levels of education had significantly lower odds of going online to look for a health care provider (high school or less: OR 0.50, 95% CI 0.33-0.76) using email or the Internet to communicate with a doctor (high school or less: OR 0.46, 95% CI 0.29-0.72), tracking their personal health information online (high school or less: OR 0.53, 95% CI 0.32-0.84), using a website to help track diet, weight, and physical activity (high school or less: OR 0.64, 95% CI 0.42-0.98; some college: OR 0.67, 95% CI 0.49-0.93), or downloading health information to a mobile device (some college: OR 0.54, 95% CI 0.33-0.89). Being female was a consistent predictor of eHealth use across health care and
Deep seismic sounding in northern Eurasia
Benz, H.M.; Unger, J.D.; Leith, W.S.; Mooney, W.D.; Solodilov, L.; Egorkin, A.V.; Ryaboy, V.Z.
For nearly 40 years, the former Soviet Union has carried out an extensive program of seismic studies of the Earth's crust and upper mantle, known as “Deep Seismic Sounding� or DSS [Piwinskii, 1979; Zverev and Kosminskaya, 1980; Egorkin and Pavlenkova, 1981; Egorkin and Chernyshov, 1983; Scheimer and Borg, 1985]. Beginning in 1939–1940 with a series of small-scale seismic experiments near Moscow, DSS profiling has broadened into a national multiinstitutional exploration effort that has completed almost 150,000 km of profiles covering all major geological provinces of northern Eurasia [Ryaboy, 1989].

population and territory); seismic risk in general; risk information and their sources; comparison between seismic risk and other natural hazards. Informative data include: Region, Province, Municipality of residence, Data compilation, Age, Sex, Place of Birth, Nationality, Marital status, Children, Level of education, Employment. The test allows to obtain the perception score for each factor: Hazard, Exposed value, Vulnerability. These scores can be put in relation with the scientific data relating to hazard, vulnerability and the exposed value. On January 2013 started a Survey in the Po Valley and Southern Apennines. The survey will be conducted via web using institutional sites of regions, provinces, municipalities, online newspapers to local spreading, etc. Preliminary data will be discussed. Improve our understanding of the perception of seismic risk would allow us to inform more effectively and to built better educational projects to mitigate risk.
CzechGeo/EPOS - Building a national data portal
Zednik, J.; Hejda, P.
CzechGeo/EPOS is the consortium of seven geoscience institutions in the Czech Republic (Institute of Geophysics AS CR Prague, Institute of Rock Structure and Mechanics AS CR Prague, Institute of Geonics AS CR Ostrava, Institute of Physics of the Earth, Masaryk University Brno, Faculty of Mathematics and Physics, Charles University Prague, Faculty of Science, Charles University Prague, and Research Institute of Geodesy, Cartography and Topography Zdiby). These institutions operate a distributed system of seismic, GPS, magnetic, gravimetric and geodynamic observatories. The operational and personal costs of CzechGeo/EPOS are mostly covered by the Ministry of education, sports and youth within the support of twelve large research infrastructures in the Czech Republic. Web pages of the project www.czechgeo.cz are being built as a data portal which should integrate all the data and services provided by the involved institutions and research infrastructures. Seismic portal offers selected portions of digital data from permanent, local and temporary seismic stations, locations of seismic events in the country and worldwide, daily seismograms from permanent observatories and local seismic network Webnet, seismic bulletins and catalogs, and macroseismic observations on the territory of the Czech Republic. Magnetic portal involves besides real-time magnetograms also recent state of geomagnetic activity and its forecast for the next day. GPS portal will provide preprocessed data from regional GPS stations. Building the national portal is closely related with the development of the Preparatory phase of the EPOS (European Plate Observing System) project.

Seismic hazard assessment of Syria using seismicity, DEM, slope, active tectonic and GIS
Ahmad, Raed; Adris, Ahmad; Singh, Ramesh
In the present work, we discuss the use of an integrated remote sensing and Geographical Information System (GIS) techniques for evaluation of seismic hazard areas in Syria. The present study is the first time effort to create seismic hazard map with the help of GIS. In the proposed approach, we have used Aster satellite data, digital elevation data (30 m resolution), earthquake data, and active tectonic maps. Many important factors for evaluation of seismic hazard were identified and corresponding thematic data layers (past earthquake epicenters, active faults, digital elevation model, and slope) were generated. A numerical rating scheme has been developed for spatial data analysis using GIS to identify ranking of parameters to be included in the evaluation of seismic hazard. The resulting earthquake potential map delineates the area into different relative susceptibility classes: high, moderate, low and very low. The potential earthquake map was validated by correlating the obtained different classes with the local probability that produced using conventional analysis of observed earthquakes. Using earthquake data of Syria and the peak ground acceleration (PGA) data is introduced to the model to develop final seismic hazard map based on Gutenberg-Richter (a and b values) parameters and using the concepts of local probability and recurrence time. The application of the proposed technique in Syrian region indicates that this method provides good estimate of seismic hazard map compared to those developed from traditional techniques (Deterministic (DSHA) and probabilistic seismic hazard (PSHA). For the first time we have used numerous parameters using remote sensing and GIS in preparation of seismic hazard map which is found to be very realistic.
Reducing Seismic Hazard and Building Capacity Through International Cooperation
Vergino, E. S.; Arakelyan, A.; Babayan, H.; Durgaryan, R.; Elashvili, M.; Godoladze, T.; Javakhishvili, Z.; Kalogeras, I.; Karakhanyan, A.; Martin, R. J.; Yetirmishli, G.
During the last 50 years, the Caucasus, Central Asia and the Caspian Sea regions have experienced several devastating earthquakes. While each country in the region has worked with its neighbors on small, ad-hoc projects to improve preparedness, deeply ingrained political and ethnic rivalries, and severely stressed economies have severely hindered sustained regional cooperation. Future damaging earthquakes are inevitable and without proper planning the negative impact on public safety, security, economics and stability in these regions will be devastating. We have, through twelve years of international scientific cooperation, focused on the development of an expanded skill base and infrastructure, through the installation of new, modern, digital seismic monitoring networks, building of historic databases, sharing seismic, geologic and geophysical data, conducting joint scientific investigations utilizing the new digital data and applying modern techniques, as well as the development of regional hazard models that the scientists of the region share with their governments and use to advise them on the best ways to mitigate the impact of a damaging earthquake. We have established specialized regional scientific task-force teams who can carry out seismological, geological and engineering studies in the epicentral zone, including the collection of new scientific data, for better understanding of seismic and geodynamic processes as well to provide emergency support in crisis and post-crisis situations in the Southern Caucasus countries. "Secrecy" in crisis and post-crisis situations in the former Soviet Union countries, as well as political instabilities, led to an absence of seismic risk reduction and prevention measures as well as little to no training of scientific-technical personnel who could take action in emergency situations. There were few opportunities for the development of a next generation of scientific experts, thus we have placed emphasis on the inclusion
Global Seismic Cross-Correlation Results: Characterizing Repeating Seismic Events
Vieceli, R.; Dodge, D. A.; Walter, W. R.
Increases in seismic instrument quality and coverage have led to increased knowledge of earthquakes, but have also revealed the complex and diverse nature of earthquake ruptures. Nonetheless, some earthquakes are sufficiently similar to each other that they produce correlated waveforms. Such repeating events have been used to investigate interplate coupling of subduction zones [e.g. Igarashi, 2010; Yu, 2013], study spatio-temporal changes in slip rate at plate boundaries [e.g. Igarashi et al., 2003], observe variations in seismic wave propagation velocities in the crust [e.g. Schaff and Beroza, 2004; Sawazaki et al., 2015], and assess inner core rotation [e.g. Yu, 2016]. The characterization of repeating events on a global scale remains a very challenging problem. An initial global seismic cross-correlation study used over 310 million waveforms from nearly 3.8 million events recorded between 1970 and 2013 to determine an initial look at global correlated seismicity [Dodge and Walter, 2015]. In this work, we analyze the spatial and temporal distribution of the most highly correlated event clusters or "multiplets" from the Dodge and Walter [2015] study. We examine how the distributions and characteristics of multiplets are effected by tectonic environment, source-station separation, and frequency band. Preliminary results suggest that the distribution of multiplets does not correspond to the tectonic environment in any obvious way, nor do they always coincide with the occurrence of large earthquakes. Future work will focus on clustering correlated pairs and working to reduce the bias introduced by non-uniform seismic station coverage and data availability. This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
Utah's Regional/Urban ANSS Seismic Network---Strategies and Tools for Quality Performance
Burlacu, R.; Arabasz, W. J.; Pankow, K. L.; Pechmann, J. C.; Drobeck, D. L.; Moeinvaziri, A.; Roberson, P. M.; Rusho, J. A.
The University of Utah's regional/urban seismic network (224 stations recorded: 39 broadband, 87 strong-motion, 98 short-period) has become a model for locally implementing the Advanced National Seismic System (ANSS) because of successes in integrating weak- and strong-motion recording and in developing an effective real-time earthquake information system. Early achievements included implementing ShakeMap, ShakeCast, point-to- multipoint digital telemetry, and an Earthworm Oracle database, as well as in-situ calibration of all broadband and strong-motion stations and submission of all data and metadata into the IRIS DMC. Regarding quality performance, our experience as a medium-size regional network affirms the fundamental importance of basics such as the following: for data acquisition, deliberate attention to high-quality field installations, signal quality, and computer operations; for operational efficiency, a consistent focus on professional project management and human resources; and for customer service, healthy partnerships---including constant interactions with emergency managers, engineers, public policy-makers, and other stakeholders as part of an effective state earthquake program. (Operational cost efficiencies almost invariably involve trade-offs between personnel costs and the quality of hardware and software.) Software tools that we currently rely on for quality performance include those developed by UUSS (e.g., SAC and shell scripts for estimating local magnitudes) and software developed by other organizations such as: USGS (Earthworm), University of Washington (interactive analysis software), ISTI (SeisNetWatch), and IRIS (PDCC, BUD tools). Although there are many pieces, there is little integration. One of the main challenges we face is the availability of a complete and coherent set of tools for automatic and post-processing to assist in achieving the goals/requirements set forth by ANSS. Taking our own network---and ANSS---to the next level
Advanced Seismic While Drilling System
Robert Radtke; John Fontenot; David Glowka
by TII. An APS Turbine Alternator powered the SeismicPULSER{trademark} to produce two Hz frequency peak signals repeated every 20 seconds. Since the ION Geophysical, Inc. (ION) seismic survey surface recording system was designed to detect a minimum downhole signal of three Hz, successful performance was confirmed with a 5.3 Hz recording with the pumps running. The two Hz signal generated by the sparker was modulated with the 3.3 Hz signal produced by the mud pumps to create an intense 5.3 Hz peak frequency signal. The low frequency sparker source is ultimately capable of generating selectable peak frequencies of 1 to 40 Hz with high-frequency spectra content to 10 kHz. The lower frequencies and, perhaps, low-frequency sweeps, are needed to achieve sufficient range and resolution for realtime imaging in deep (15,000 ft+), high-temperature (150 C) wells for (a) geosteering, (b) accurate seismic hole depth, (c) accurate pore pressure determinations ahead of the bit, (d) near wellbore diagnostics with a downhole receiver and wired drill pipe, and (e) reservoir model verification. Furthermore, the pressure of the sparker bubble will disintegrate rock resulting in an increased overall rates of penetration. Other applications for the SeismicPULSER{trademark} technology are to deploy a low-frequency source for greater range on a wireline for Reverse Vertical Seismic Profiling (RVSP) and Cross-Well Tomography. Commercialization of the technology is being undertaken by first contacting stakeholders to define the value proposition for rig site services utilizing SeismicPULSER{trademark} technologies. Stakeholders include national oil companies, independent oil companies, independents, service companies, and commercial investors. Service companies will introduce a new Drill Bit SWD service for deep HTHP wells. Collaboration will be encouraged between stakeholders in the form of joint industry projects to develop prototype tools and initial field trials. No barriers have been
OGS improvements in the year 2011 in running the Northeastern Italy Seismic Network
Bragato, P. L.; Pesaresi, D.; Saraò, A.; Di Bartolomeo, P.; Durı, G.
The Centro di Ricerche Sismologiche (CRS, Seismological Research Center) of the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS, Italian National Institute for Oceanography and Experimental Geophysics) in Udine (Italy) after the strong earthquake of magnitude M=6.4 occurred in 1976 in the Italian Friuli-Venezia Giulia region, started to operate the Northeastern Italy Seismic Network: it currently consists of 15 very sensitive broad band and 21 simpler short period seismic stations, all telemetered to and acquired in real time at the OGS-CRS data center in Udine. Real time data exchange agreements in place with other Italian, Slovenian, Austrian and Swiss seismological institutes lead to a total number of about 100 seismic stations acquired in real time, which makes the OGS the reference institute for seismic monitoring of Northeastern Italy. Since 2002 OGS-CRS is using the Antelope software suite on several workstations plus a SUN Cluster as the main tool for collecting, analyzing, archiving and exchanging seismic data, initially in the framework of the EU Interreg IIIA project "Trans-national seismological networks in the South-Eastern Alps". SeisComP is also used as a real time data exchange server tool. In order to improve the seismological monitoring of the Northeastern Italy area, at OGS-CRS we tuned existing programs and created ad hoc ones like: a customized web server named PickServer to manually relocate earthquakes, a script for automatic moment tensor determination, scripts for web publishing of earthquake parametric data, waveforms, state of health parameters and shaking maps, noise characterization by means of automatic spectra analysis, and last but not least scripts for email/SMS/fax alerting. The OGS-CRS Real Time Seismological website (RTS, http://rts.crs.inogs.it/) operative since several years was initially developed in the framework of the Italian DPC-INGV S3 Project: the RTS website shows classic earthquake locations
Archive of Digitized Analog Boomer Seismic Reflection Data Collected from Lake Pontchartrain, Louisiana, to Mobile Bay, Alabama, During Cruises Onboard the R/V ERDA-1, June and August 1992
Sanford, Jordan M.; Harrison, Arnell S.; Wiese, Dana S.; Flocks, James G.
In June and August of 1992, the U.S. Geological Survey (USGS) conducted geophysical surveys to investigate the shallow geologic framework from Lake Pontchartrain, Louisiana, to Mobile Bay, Alabama. This work was conducted onboard the Argonne National Laboratory's R/V ERDA-1 as part of the Mississippi/Alabama Pollution Project. This report is part of a series to digitally archive the legacy analog data collected from the Mississippi-Alabama SHelf (MASH). The MASH data rescue project is a cooperative effort by the USGS and the Minerals Management Service (MMS). A standardized naming convention was established to allow for better management of scanned trackline images within the MASH data rescue project. Each cruise received a unique field activity ID based on the year the data were collected, the first two digits of the survey vessel name, and the number of cruises made (to date) by that vessel that year (i.e. 92ER2 represents the second cruise made by the R/V ERDA-1 in 1992.) The new field activity IDs 92ER2 and 92ER4 presented in this report were originally referred to as ERDA 92-2 and ERDA 92-4 at the USGS in St. Petersburg, FL, and 92010 and 92037 at the USGS in Woods Hole, MA. A table showing the naming convention lineage for cruise IDs in the MASH data rescue series is included as a PDF. This report serves as an archive of high resolution scanned Tagged Image File Format (TIFF) and Graphics Interchange Format (GIF) images of the original boomer paper records, navigation files, trackline maps, Geographic Information System (GIS) files, cruise logs, and formal Federal Geographic Data Committee (FGDC) metadata for cruises 92ER2 and 92ER4. The boomer system uses an acoustic energy source called a plate, which consists of capacitors charged to a high voltage and discharged through a transducer in the water. The source is towed on a sled, at sea level, and when discharged emits a short acoustic pulse, or shot, which propagates through the water and sediment column
The Southern Kansas Seismic Network
Terra, F. M.
Historically aseismic Harper and Sumner counties in Southern Kansas experienced a dramatic increase in seismicity beginning in early 2014, coincident with the development of new oil production in the Mississippi Lime Play. In order to better understand the potential relationships between seismicity and oil development, the USGS installed a real-time telemetered seismic network in cooperation with the Kansas Geological Survey, the Kansas Corporation Commission, the Kansas Department of Health and Environment, Harper County, and the Oklahoma Geological Survey. The network began operation in March 2014 with an initial deployment of 5 NetQuakes accelerometers and by July 2014 had expanded to include 10 broadband sites. The network currently has 14 stations, all with accelerometers and 12 with broadband seismometers. The network has interstation spacing of 15 - 25 km and typical azimuthal gap of 80 for well-located events. Data are continuously streamed to IRIS at 200 samples per second from most sites. Earthquake locations are augmented with additional stations from the USGS National Network, Oklahoma Geological Survey Seismic Network, Kansas Seismic Monitoring Network and the Enid Oklahoma Network. Since the spring of 2014 over 7500 earthquakes have been identified with data from this network, 1400 of which have been manually timed and cataloged. Focal depths for earthquakes typically range between 2 and 7 km. The catalog is available at earthquake.usgs.gov/earthquakes/search/ under network code 'Ismpkansas'. The network recorded the largest known earthquake in Harper County, Mw 4.3, on October 2, 2014 and in Sumner County, Mw 4.9, on November 12, 2014. Recorded ground motions at the epicenter of the October earthquake were 0.70 g (PGA) and 12 cm/s (PGV). These high ground motion values agree with near-source recordings made by other USGS temporary deployments in the U. S. midcontinent, indicating a significant shaking hazard from such shallow, moderate
Digitized Database of Old Seismograms Recorder in Romania
Paulescu, Daniel; Rogozea, Maria; Popa, Mihaela; Radulian, Mircea
The aim of this paper is to describe a managing system for a unique Romanian database of historical seismograms and complementary documentation (metadata) and its dissemination and analysis procedure. For this study, 5188 historical seismograms recorded between 1903 and 1957 by the Romanian seismological observatories (Bucharest-Filaret, Focşani, Bacău, Vrincioaia, Câmpulung-Muscel, Iaşi) were used. In order to reconsider the historical instrumental data, the analog seismograms are converted to digital images and digital waveforms (digitization/ vectorialisation). First, we applied a careful scanning procedure of the seismograms and related material (seismic bulletins, station books, etc.). In a next step, the high resolution scanned seismograms will be processed to obtain the digital/numeric waveforms. We used a Colortrac Smartlf Cx40 scanner which provides images in TIFF or JPG format. For digitization the algorithm Teseo2 developed by the National Institute of Geophysics and Volcanology in Rome (Italy), within the framework of the SISMOS Project, will be used.
Tunnel Detection Using Seismic Methods
Miller, R.; Park, C. B.; Xia, J.; Ivanov, J.; Steeples, D. W.; Ryden, N.; Ballard, R. F.; Llopis, J. L.; Anderson, T. S.; Moran, M. L.; Ketcham, S. A.
Surface seismic methods have shown great promise for use in detecting clandestine tunnels in areas where unauthorized movement beneath secure boundaries have been or are a matter of concern for authorities. Unauthorized infiltration beneath national borders and into or out of secure facilities is possible at many sites by tunneling. Developments in acquisition, processing, and analysis techniques using multi-channel seismic imaging have opened the door to a vast number of near-surface applications including anomaly detection and delineation, specifically tunnels. Body waves have great potential based on modeling and very preliminary empirical studies trying to capitalize on diffracted energy. A primary limitation of all seismic energy is the natural attenuation of high-frequency energy by earth materials and the difficulty in transmitting a high- amplitude source pulse with a broad spectrum above 500 Hz into the earth. Surface waves have shown great potential since the development of multi-channel analysis methods (e.g., MASW). Both shear-wave velocity and backscatter energy from surface waves have been shown through modeling and empirical studies to have great promise in detecting the presence of anomalies, such as tunnels. Success in developing and evaluating various seismic approaches for detecting tunnels relies on investigations at known tunnel locations, in a variety of geologic settings, employing a wide range of seismic methods, and targeting a range of uniquely different tunnel geometries, characteristics, and host lithologies. Body-wave research at the Moffat tunnels in Winter Park, Colorado, provided well-defined diffraction-looking events that correlated with the subsurface location of the tunnel complex. Natural voids related to karst have been studied in Kansas, Oklahoma, Alabama, and Florida using shear-wave velocity imaging techniques based on the MASW approach. Manmade tunnels, culverts, and crawl spaces have been the target of multi-modal analysis
Korea Integrated Seismic System tool(KISStool) for seismic monitoring and data sharing at the local data center
Park, J.; Chi, H. C.; Lim, I.; Jeong, B.
The Korea Integrated Seismic System(KISS) is a back-bone seismic network which distributes seismic data to different organizations in near-real time at Korea. The association of earthquake monitoring institutes has shared their seismic data through the KISS from 2003. Local data centers operating remote several stations need to send their free field seismic data to NEMA(National Emergency Management Agency) by the law of countermeasure against earthquake hazard in Korea. It is very important the efficient tool for local data centers which want to rapidly detect local seismic intensity and to transfer seismic event information toward national wide data center including PGA, PGV, dominant frequency of P-wave, raw data, and etc. We developed the KISStool(Korea Integrated Seismic System tool) for easy and convenient operation seismic network in local data center. The KISStool has the function of monitoring real time waveforms by clicking station icon on the Google map and real time variation of PGA, PGV, and other data by opening the bar type monitoring section. If they use the KISStool, any local data center can transfer event information to NEMA(National Emergency Management Agency), KMA(Korea Meteorological Agency) or other institutes through the KISS using UDP or TCP/IP protocols. The KISStool is one of the most efficient methods to monitor and transfer earthquake event at local data center in Korea. KIGAM will support this KISStool not only to the member of the monitoring association but also local governments.
Preliminary seismic studies at Ceboruco Volcano
Escudero, C. R.; Nunez-Cornu, F. J.; Ochoa, J.; Robles, F. J.
Many societies and their economies endure the disastrous consequences of destructive volcanic eruptions. The Ceboruco stratovolcano is located at the west of the Mexican volcanic belt at 21.125o north, 76 km from the pacific coast and 2,280 meters above sea level. It has an eruptive recurrence of 200 years and its last activity was at 1875. This natural hazard could affect more than eight communities and important highways. Scientific knowledge constitutes the only way to avoid or at least to mitigate the negative effects of an eventual eruptive event, accordingly the main objective of this project is monitor and analyze the potential destructive effects of the Ceboruco volcano. Seismic studies began at 2003 with the deployment of one MARSlite station equipped LE3d (1Hz) sensor. Station that works until 2009 and allow us to identify and characterize the seismic activity associated to the volcano;. Since March 2012 we installed four seismic stations, each includes a digital acquisition system TAURUS of Nanometrix and a Lennartz 3D lite seismometer. Batteries are change and data collected monthly. We use the data to establish the average seismic activity rate; we also aim to corroborate previous studies that showed four families of seismic events; and to localize and make preliminary evaluations of the events.

Geomorphology and seismic risk
Panizza, Mario
The author analyses the contributions provided by geomorphology in studies suited to the assessment of seismic risk: this is defined as function of the seismic hazard, of the seismic susceptibility, and of the vulnerability. The geomorphological studies applicable to seismic risk assessment can be divided into two sectors: (a) morpho-neotectonic investigations conducted to identify active tectonic structures; (b) geomorphological and morphometric analyses aimed at identifying the particular situations that amplify or reduce seismic susceptibility. The morpho-neotectonic studies lead to the identification, selection and classification of the lineaments that can be linked with active tectonic structures. The most important geomorphological situations that can condition seismic susceptibility are: slope angle, debris, morphology, degradational slopes, paleo-landslides and underground cavities.
The New Italian Seismic Hazard Model
Marzocchi, W.; Meletti, C.; Albarello, D.; D'Amico, V.; Luzi, L.; Martinelli, F.; Pace, B.; Pignone, M.; Rovida, A.; Visini, F.
In 2015 the Seismic Hazard Center (Centro Pericolosità Sismica - CPS) of the National Institute of Geophysics and Volcanology was commissioned of coordinating the national scientific community with the aim to elaborate a new reference seismic hazard model, mainly finalized to the update of seismic code. The CPS designed a roadmap for releasing within three years a significantly renewed PSHA model, with regard both to the updated input elements and to the strategies to be followed. The main requirements of the model were discussed in meetings with the experts on earthquake engineering that then will participate to the revision of the building code. The activities were organized in 6 tasks: program coordination, input data, seismicity models, ground motion predictive equations (GMPEs), computation and rendering, testing. The input data task has been selecting the most updated information about seismicity (historical and instrumental), seismogenic faults, and deformation (both from seismicity and geodetic data). The seismicity models have been elaborating in terms of classic source areas, fault sources and gridded seismicity based on different approaches. The GMPEs task has selected the most recent models accounting for their tectonic suitability and forecasting performance. The testing phase has been planned to design statistical procedures to test with the available data the whole seismic hazard models, and single components such as the seismicity models and the GMPEs. In this talk we show some preliminary results, summarize the overall strategy for building the new Italian PSHA model, and discuss in detail important novelties that we put forward. Specifically, we adopt a new formal probabilistic framework to interpret the outcomes of the model and to test it meaningfully; this requires a proper definition and characterization of both aleatory variability and epistemic uncertainty that we accomplish through an ensemble modeling strategy. We use a weighting scheme
Seismicity of Cascade Volcanoes: Characterization and Comparison
Thelen, W. A.
Here we summarize and compare the seismicity around each of the Very High Threat Volcanoes of the Cascade Range of Washington, Oregon and California as defined by the National Volcanic Early Warning System (NVEWS) threat assessment (Ewert et al., 2005). Understanding the background seismic activity and processes controlling it is critical for assessing changes in seismicity and their implications for volcanic hazards. Comparing seismicity at different volcanic centers can help determine what critical factors or processes affect the observed seismic behavior. Of the ten Very High Threat Volcanoes in the Cascade Range, five volcanoes are consistently seismogenic when considering earthquakes within 10 km of the volcanic center or caldera edge (Mount Rainier, Mount St. Helens, Mount Hood, Newberry Caldera, Lassen Volcanic Center). Other Very High Threat volcanoes (South Sister, Mount Baker, Glacier Peak, Crater Lake and Mount Shasta) have comparatively low rates of seismicity and not enough recorded earthquakes to calculate catalog statistics. Using a swarm definition of 3 or more earthquakes occurring in a day with magnitudes above the largest of the network's magnitude of completenesses (M 0.9), we find that Lassen Volcanic Center is the "swarmiest" in terms of percent of seismicity occurring in swarms, followed by Mount Hood, Mount St. Helens and Rainier. The predominance of swarms at Mount Hood may be overstated, as much of the seismicity is occurring on surrounding crustal faults (Jones and Malone, 2005). Newberry Caldera has a relatively short record of seismicity since the permanent network was installed in 2011, however there have been no swarms detected as defined here. Future work will include developing discriminates for volcanic versus tectonic seismicity to better filter the seismic catalog and more precise binning of depths at some volcanoes so that we may better consider different processes.

Seismic Risk Perception compared with seismic Risk Factors
Crescimbene, Massimo; La Longa, Federica; Pessina, Vera; Pino, Nicola Alessandro; Peruzza, Laura
The communication of natural hazards and their consequences is one of the more relevant ethical issues faced by scientists. In the last years, social studies have provided evidence that risk communication is strongly influenced by the risk perception of people. In order to develop effective information and risk communication strategies, the perception of risks and the influencing factors should be known. A theory that offers an integrative approach to understanding and explaining risk perception is still missing. To explain risk perception, it is necessary to consider several perspectives: social, psychological and cultural perspectives and their interactions. This paper presents the results of the CATI survey on seismic risk perception in Italy, conducted by INGV researchers on funding by the DPC. We built a questionnaire to assess seismic risk perception, with a particular attention to compare hazard, vulnerability and exposure perception with the real data of the same factors. The Seismic Risk Perception Questionnaire (SRP-Q) is designed by semantic differential method, using opposite terms on a Likert scale to seven points. The questionnaire allows to obtain the scores of five risk indicators: Hazard, Exposure, Vulnerability, People and Community, Earthquake Phenomenon. The questionnaire was administered by telephone interview (C.A.T.I.) on a statistical sample at national level of over 4,000 people, in the period January -February 2015. Results show that risk perception seems be underestimated for all indicators considered. In particular scores of seismic Vulnerability factor are extremely low compared with house information data of the respondents. Other data collected by the questionnaire regard Earthquake information level, Sources of information, Earthquake occurrence with respect to other natural hazards, participation at risk reduction activities and level of involvement. Research on risk perception aims to aid risk analysis and policy-making by

Seismic activity in northeastern Brazill-new perspectives
Ferreira, J. M.; Do Nascimento, A. F.; Vilar, C. S.; Bezerra, F. H.; Assumpcao, M.; Berrocal, J.; Fuck, R. A.
Northeastern Brazil is the most seismic active region in the country. Some earthquakes with magnitude above 5.0 and intensity VII MM associated with swam-like seismic activity lasting for many years are a serious social concern. Since the 1980's macroseismic and instrumental surveys have been carried out in this region and they are an important data archive which allows the composition of a reliable catalogue of seismic activity for this region. Among the many scientific results it was possible to identify the main seismogenic areas, obtain reliable hypocentres and focal mechanisms. As a consequence, it was possible also to analyse the relationship between seismicity and geological features. It was also possible to determined maximum horizontal stress direction for the region. An important induced seismic activity case has also been reported in the area as being a classical example of pore pressure diffusion triggering mechanism. The majority of the results were obtained using analogic data. Recently, a new research project is being conducted and will allow us to provide a regional scale monitoring with 6 broad-band stations and a new portable six station digital seismic network equipped with short- period sensors. Thus, with the continuous seismic activity in the area we trust that the results of this project will increase the present knowledge of seismic activity in northeastern Brazil.
Digital signal processing and interpretation of full waveform sonic log for well BP-3-USGS, Great Sand Dunes National Park and Preserve, Alamosa County, Colorado
Burke, Lauri
Along the Great Sand Dunes National Park and Preserve boundary (fig. 1), 10 monitoring wells were drilled by the National Park Service in order to monitor water flow in an unconfined aquifer spanning the park boundary. Adjacent to the National Park Service monitoring well named Boundary Piezometer Well No. 3, or BP-3, the U.S. Geological Survey (USGS) drilled the BP-3-USGS well. This well was drilled from September 14 through 17, 2009, to a total depth of 99.4 meters (m) in order to acquire additional subsurface information. The BP-3-USGS well is located at lat 37 degrees 43'18.06' and long -105 degrees 43'39.30' at a surface elevation of 2,301 m. Approximately 23 m of core was recovered beginning at a depth of 18 m. Drill cuttings were also recovered. The wireline geophysical logs acquired in the well include natural gamma ray, borehole caliper, temperature, full waveform sonic, density, neutron, resistivity, and induction logs. The BP-3-USGS well is now plugged and abandoned. This report details the full waveform digital signal processing methodology and the formation compressional-wave velocities determined for the BP-3-USGS well. These velocity results are compared to several velocities that are commonly encountered in the subsurface. The density log is also discussed in context of these formation velocities.
Induced Seismicity Potential of Energy Technologies

Earthquakes attributable to human activities-``induced seismic events''-have received heightened public attention in the United States over the past several years. Upon request from the U.S. Congress and the Department of Energy, the National Research Council was asked to assemble a committee of experts to examine the scale, scope, and consequences of seismicity induced during fluid injection and withdrawal associated with geothermal energy development, oil and gas development, and carbon capture and storage (CCS). The committee's report, publicly released in June 2012, indicates that induced seismicity associated with fluid injection or withdrawal is caused in most cases by change in pore fluid pressure and/or change in stress in the subsurface in the presence of faults with specific properties and orientations and a critical state of stress in the rocks. The factor that appears to have the most direct consequence in regard to induced seismicity is the net fluid balance (total balance of fluid introduced into or removed from the subsurface). Energy technology projects that are designed to maintain a balance between the amount of fluid being injected and withdrawn, such as most oil and gas development projects, appear to produce fewer seismic events than projects that do not maintain fluid balance. Major findings from the study include: (1) as presently implemented, the process of hydraulic fracturing for shale gas recovery does not pose a high risk for inducing felt seismic events; (2) injection for disposal of waste water derived from energy technologies does pose some risk for induced seismicity, but very few events have been documented over the past several decades relative to the large number of disposal wells in operation; and (3) CCS, due to the large net volumes of injected fluids suggested for future large-scale carbon storage projects, may have potential for inducing larger seismic events.

Seismic activity monitoring in the Izvorul Muntelui dam region
Borleanu, Felix; Otilia Placinta, Anca; Popa, Mihaela; Adelin Moldovan, Iren; Popescu, Emilia
Earthquakes occurrences near the artificial water reservoirs are caused by stress variation due to the weight of water, weakness of fractures or faults and increasing of pore pressure in crustal rocks. In the present study we aim to investigate how Izvorul Muntelui dam, located in the Eastern Carpathians influences local seismicity. For this purpose we selected from the seismic bulletins computed within National Data Center of National Institute for Earth Physics, Romania, crustal events occurred between 984 and 2015 in a range of 0.3 deg around the artificial lake. Subsequently to improve the seismic monitoring of the region we applied a cross-correlation detector on the continuous recordings of Bicaz (BIZ) seismic stations. Besides the tectonic events we detected sources within this region that periodically generate artificial evens. We couldn't emphasize the existence of a direct correlation between the water level variations and natural seismicity of the investigated area.
Coherent Waves in Seismic Researches
Emanov, A.; Seleznev, V. S.
Development of digital processing algorithms of seismic wave fields for the purpose of useful event picking to study environment and other objects is the basis for the establishment of new seismic techniques. In the submitted paper a fundamental property of seismic wave field coherence is used. The authors extended conception of coherence types of observed wave fields and devised a technique of coherent component selection from observed wave field. Time coherence and space coherence are widely known. In this paper conception "parameter coherence" has been added. The parameter by which wave field is coherent can be the most manifold. The reason is that the wave field is a multivariate process described by a set of parameters. Coherence in the first place means independence of linear connection in wave field of parameter. In seismic wave fields, recorded in confined space, in building-blocks and stratified mediums time coherent standing waves are formed. In prospecting seismology at observation systems with multiple overlapping head waves are coherent by parallel correlation course or, in other words, by one measurement on generalized plane of observation system. For detail prospecting seismology at observation systems with multiple overlapping on basis of coherence property by one measurement of area algorithms have been developed, permitting seismic records to be converted to head wave time sections which have neither reflected nor other types of waves. Conversion in time section is executed on any specified observation base. Energy storage of head waves relative to noise on basis of multiplicity of observation system is realized within area of head wave recording. Conversion on base below the area of wave tracking is performed with lack of signal/noise ratio relative to maximum of this ratio, fit to observation system. Construction of head wave time section and dynamic plots a basis of automatic processing have been developed, similar to CDP procedure in method of
ULF radio monitoring network in a seismic area
Toader, Victorin; Moldovan, Iren-Adelina; Ionescu, Constantin; Marmureanu, Alexandru
ULF monitoring is a part of a multidisciplinary network (AeroSolSys) located in Vrancea (Curvature Carpathian Mountains). Four radio receivers (100 kHz - microwave) placed on faults in a high seismic area characterized by deep earthquakes detect fairly weak radio waves. The radio power is recorded in correlation with many other parameters related to near surface low atmosphere phenomena (seismicity, solar radiation, air ionization, electromagnetic activity, radon, CO2 concentration, atmospheric pressure, telluric currents, infrasound, seismo-acoustic emission, meteorological information). We follow variations in the earth's surface propagate radio waves avoiding reflection on ionosphere. For this reason the distance between stations is less than 60 km and the main source of emission is near (Bod broadcasting transmitter for long- and medium-wave radio, next to Brasov city). In the same time tectonic stress affects the radio propagation in air and it could generates ULF waves in ground (LAI coupling). To reduce the uncertainty is necessary to monitor a location for extended periods of time to outline local and seasonal fluctuations. Solar flares do not affect seismic activity but they produce disturbances in telecommunications networks and power grids. Our ULF monitoring correlated with two local magnetometers does not indicate this so far with our receivers. Our analysis was made during magnetic storms with Kp 7 and 8 according to NOAA satellites. To correlate the results we implemented an application that monitors the satellite EUTELSAT latency compared to WiMAX land communication in the same place. ULF band radio monitoring showed that our receiver is dependent on temperature and that it is necessary to introduce a band pass filter in data analysis. ULF data acquisition is performed by Kinemetrics and National Instruments digitizers with a sampling rate of 100 Hz in Miniseed format and then converted into text files with 1 Hz rate for analysis in very low
Topogrid Derived 10 Meter Resolution Digital Elevation Model of the Shenandoah National Park and Surrounding Region, Virginia
Chirico, Peter G.; Tanner, Seth D.
Explanation The purpose of developing a new 10m resolution DEM of the Shenandoah National Park Region was to more accurately depict geologic structure, surfical geology, and landforms of the Shenandoah National Park Region in preparation for automated landform classification. Previously, only a 30m resolution DEM was available through the National Elevation Dataset (NED). During production of the Shenandoah10m DEM of the Park the Geography Discipline of the USGS completed a revised 10m DEM to be included into the NED. However, different methodologies were used to produce the two similar DEMs. The ANUDEM algorithm was used to develop the Shenadoah DEM data. This algorithm allows for the inclusion of contours, streams, rivers, lake and water body polygons as well as spot height data to control the elevation model. A statistical analysis using over 800 National Geodetic Survey (NGS) first and second order vertical control points reveals that the Shenandoah10m DEM, produced as a part of the Appalachian Blue Ridge Landscape project, has a vertical accuracy of ?4.87 meters. The metadata for the 10m NED data reports a vertical accuracy of ?7m. A table listing the NGS control points, the elevation comparison, and the RMSE for the Shenandoah10m DEM is provided. The process of automated terrain classification involves developing statistical signatures from the DEM for each type of surficial deposit and landform type. The signature will be a measure of several characteristics derived from the elevation data including slope, aspect, planform curvature, and profile curvature. The quality of the DEM is of critical importance when extracting terrain signatures. The highest possible horizontal and vertical accuracy is required. The more accurate Shenandoah 10m DEM can now be analyzed and integrated with the geologic observations to yield statistical correlations between the two in the development of landform and surface geology mapping projects.

The most prominent geologic features of the Reserve are the spectacular rock spires that attracted visitors, beginning with commentary in the journals of travelers to California during the Gold Rush of 1849. The tectonic history is outlined, and descriptions of landscape processes, a newly discovered Quaternary fault, and features of the pinnacles are presented.
Using Seismic Interferometry to Investigate Seismic Swarms
Matzel, E.; Morency, C.; Templeton, D. C.
Seismicity provides a direct means of measuring the physical characteristics of active tectonic features such as fault zones. Hundreds of small earthquakes often occur along a fault during a seismic swarm. This seismicity helps define the tectonically active region. When processed using novel geophysical techniques, we can isolate the energy sensitive to the fault, itself. Here we focus on two methods of seismic interferometry, ambient noise correlation (ANC) and the virtual seismometer method (VSM). ANC is based on the observation that the Earth's background noise includes coherent energy, which can be recovered by observing over long time periods and allowing the incoherent energy to cancel out. The cross correlation of ambient noise between a pair of stations results in a waveform that is identical to the seismogram that would result if an impulsive source located at one of the stations was recorded at the other, the Green function (GF). The calculation of the GF is often stable after a few weeks of continuous data correlation, any perturbations to the GF after that point are directly related to changes in the subsurface and can be used for 4D monitoring.VSM is a style of seismic interferometry that provides fast, precise, high frequency estimates of the Green's function (GF) between earthquakes. VSM illuminates the subsurface precisely where the pressures are changing and has the potential to image the evolution of seismicity over time, including changes in the style of faulting. With hundreds of earthquakes, we can calculate thousands of waveforms. At the same time, VSM collapses the computational domain, often by 2-3 orders of magnitude. This allows us to do high frequency 3D modeling in the fault region. Using data from a swarm of earthquakes near the Salton Sea, we demonstrate the power of these techniques, illustrating our ability to scale from the far field, where sources are well separated, to the near field where their locations fall within each other

Does Digital Ad Exposure Influence Information-Seeking Behavior Online? Evidence From the 2012 Tips From Former Smokers National Tobacco Prevention Campaign.
Kim, Annice; Hansen, Heather; Duke, Jennifer; Davis, Kevin; Alexander, Robert; Rowland, Amy; Mitchko, Jane
Measuring the impact of online health campaigns is challenging. Ad click-through rates are traditionally used to measure campaign reach, but few Internet users ever click on ads. Alternatively, self-reported exposure to digital ads would be prone to recall bias. Furthermore, there may be latency effects whereby people do not click on ads when exposed but visit the promoted website or conduct campaign-related searches later. Online panels that unobtrusively collect panelists' Web behavior data and link ad exposure to website visits and searches can more reliably assess the impact of digital ad exposure. From March to June 2012, the Centers for Disease Control and Prevention aired the national Tips From Former Smokers (Tips 2012) media campaign designed to encourage current smokers to quit. Advertisements ran across media channels, and the digital ads directed users to the Tips 2012 campaign website. Our aim was to examine whether exposure to Tips 2012 digital ads influenced information-seeking behaviors online. ComScore mined its panelists' Web behavior data for unique codes that would indicate exposure to Tips 2012 ads, regardless of whether panelists clicked the ad or not. A total of 15,319 US adults were identified as having been exposed to a Tips 2012 campaign ad. An equal number of unexposed adults (N=15,319) were identified and matched on demographics and Internet use behavior to the exposed group. Panelists' Web behavior data were mined for up to 4 weeks after initial Tips 2012 ad exposure to determine whether they visited the Tips 2012 campaign website or other cessation-related websites (eg, nicotine replacement therapy site) or conducted searches for campaign-related topics (eg, quit smoking). The proportion of exposed adults visiting the Tips 2012 sites increased from 0.4% in Week 1 to 0.9% 4 weeks after ad exposure, and these rates were significantly higher than in the unexposed group (0.1% in Week 1 to 0.4% in Week 4, P<.001) across all weeks examined

R/V EWING seismic source array calibrations: 2003
Diebold, J.; Webb, S.; Tolstoy, M.; Rawson, M.; Holmes, C.; Bohnenstiehl, D.; Chapp, E.
In the Northern Gulf of Mexico, May, 2003, an NSF-funded effort was carried out to obtain calibrated measurements of the various airgun arrays deployed by R/V EWING during its seismic surveys. The motivations for this were several: to ground-truth the modeling upon which safety radii for marine mammal mitigation are established; to obtain broadband digitized signals which will accurately define the full spectral content of airgun signatures; to investigate the effects of seafloor interactions and their contribution to the acoustic noise levels from seismic sources. For this purpose, a digital, remotely telemetering spar buoy was designed and assembled; affording interactive control over the choice of two hydrophone channels, four fixed gain settings and four digitizing rates [6,250 - 50,000 Hz.] Three deployments were planned: a deep-water site, suitable for comparison of actual signals with modeled results; a shallow-water [25 - 50m] site where the effects of bottom interaction would be strongest; and a continental-slope site, which represents the favored habitat of many cetacean species. Methodology was developed which enabled the sequential discharge of four subarrays of 6, 10, 12 and 20 airguns. A separate run was made with two "GI" airguns, the favored high resolution survey source. An Incidental Harassment Authorization and a Biological Opinion, including an Incidental Take Statement were issued for the project by National Marine Fisheries, and a suite of marine mammal observation and mitigation procedures was followed. The deep and shallow water sites were occupied, and some 440 airgun signals were recorded. The slope site work was cancelled due to weather too poor for accurate marine mammal observation, but calibration was subsequently carried out with an exploration industry source vessel in a similar environment. Preliminary results indicate that the mitigation modeling is accurate, though somewhat conservative; that the radiated energy from airgun arrays
Seismic Wave Propagation
Wu, Xianyun; Wu, Ru-Shan
A seismic wave is a mechanical disturbance or energy packet that can propagate from point to point in the Earth. Seismic waves can be generated by a sudden release of energy such as an earthquake, volcanic eruption, or chemical explosion. There are several types of seismic waves, often classified as body waves, which propagate through the volume of the Earth, and surface waves, which travel along the surface of the Earth. Compressional and shear waves are the two main types of body wave and Rayleigh and Love waves are the most common forms of surface wave.
Using Antelope and Seiscomp in the framework of the Romanian Seismic Network
Marius Craiu, George; Craiu, Andreea; Marmureanu, Alexandru; Neagoe, Cristian
The National Institute for Earth Physics (NIEP) operates a real-time seismic network designed to monitor the seismic activity on the Romania territory, dominated by the Vrancea intermediate-depth (60-200 km) earthquakes. The NIEP real-time network currently consists of 102 stations and two seismic arrays equipped with different high quality digitizers (Kinemetrics K2, Quanterra Q330, Quanterra Q330HR, PS6-26, Basalt), broadband and short period seismometers (CMG3ESP, CMG40T, KS2000, KS54000, KS2000, CMG3T, STS2, SH-1, S13, Mark l4c, Ranger, Gs21, Mark 22) and acceleration sensors (Episensor Kinemetrics). The primary goal of the real-time seismic network is to provide earthquake parameters from more broad-band stations with a high dynamic range, for more rapid and accurate computation of the locations and magnitudes of earthquakes. The Seedlink and AntelopeTM program packages are completely automated Antelope seismological system is run at the Data Center in Măgurele. The Antelope data acquisition and processing software is running for real-time processing and post processing. The Antelope real-time system provides automatic event detection, arrival picking, event location, and magnitude calculation. It also provides graphical displays and automatic location within near real time after a local, regional or teleseismic event has occurred SeisComP 3 is another automated system that is run at the NIEP and which provides the following features: data acquisition, data quality control, real-time data exchange and processing, network status monitoring, issuing event alerts, waveform archiving and data distribution, automatic event detection and location, easy access to relevant information about stations, waveforms, and recent earthquakes. The main goal of this paper is to compare both of these data acquisitions systems in order to improve their detection capabilities, location accuracy, magnitude and depth determination and reduce the RMS and other location errors.
Method of migrating seismic records
Ober, Curtis C.; Romero, Louis A.; Ghiglia, Dennis C.
The present invention provides a method of migrating seismic records that retains the information in the seismic records and allows migration with significant reductions in computing cost. The present invention comprises phase encoding seismic records and combining the encoded seismic records before migration. Phase encoding can minimize the effect of unwanted cross terms while still allowing significant reductions in the cost to migrate a number of seismic records.
Seismic sequences in the Sombrero Seismic Zone
Pulliam, J.; Huerfano, V. A.; ten Brink, U.; von Hillebrandt, C.
The northeastern Caribbean, in the vicinity of Puerto Rico and the Virgin Islands, has a long and well-documented history of devastating earthquakes and tsunamis, including major events in 1670, 1787, 1867, 1916, 1918, and 1943. Recently, seismicity has been concentrated to the north and west of the British Virgin Islands, in the region referred to as the Sombrero Seismic Zone by the Puerto Rico Seismic Network (PRSN). In the combined seismicity catalog maintained by the PRSN, several hundred small to moderate magnitude events can be found in this region prior to 2006. However, beginning in 2006 and continuing to the present, the rate of seismicity in the Sombrero suddenly increased, and a new locus of activity developed to the east of the previous location. Accurate estimates of seismic hazard, and the tsunamigenic potential of seismic events, depend on an accurate and comprehensive understanding of how strain is being accommodated in this corner region. Are faults locked and accumulating strain for release in a major event? Or is strain being released via slip over a diffuse system of faults? A careful analysis of seismicity patterns in the Sombrero region has the potential to both identify faults and modes of failure, provided the aggregation scheme is tuned to properly identify related events. To this end, we experimented with a scheme to identify seismic sequences based on physical and temporal proximity, under the assumptions that (a) events occur on related fault systems as stress is refocused by immediately previous events and (b) such 'stress waves' die out with time, so that two events that occur on the same system within a relatively short time window can be said to have a similar 'trigger' in ways that two nearby events that occurred years apart cannot. Patterns that emerge from the identification, temporal sequence, and refined locations of such sequences of events carry information about stress accommodation that is obscured by large clouds of
Participation in the Apollo passive seismic experiment
Press, F.; Toksoez, M. N.; Dainty, A.
Computer programs which were written to read digital tapes containing lunar seismic data were studied. Interpreting very early parts of the lunar seismogram as seismic body-wave phases enabled the determination of the structure of the outer part of the moon in the Fra Mauro region. The crust in the Fra Mauro region is 60 to 65 km-thick, overlaying a high velocity mantle. The crust is further divided into an upper part, 25 km thick, apparently made of material similar to the surficial basalts, and a lower part of seemingly different composition, possibly an anorthositic gabbro. The generation of the exceedingly long reverberating wave-train observed in lunar seismogram was also studied. This is believed to be due to an intense scattering layer with very high quality coefficient overlying a more homogeneous elastic medium. Titles and abstracts of related published papers are included.

Important supplementary information is included in two appendices: a survey of regional seismic networks and implementation strategies for revitalization of regional seismic networks.
Deepwater seismic acquisition technology
Caldwell, J.
Although truly new technology is not required for successful acquisition of seismic data in deep Gulf of Mexico waters, it is helpful to review some basic aspects of these seismic surveys. Additionally, such surveys are likely to see early use of some emerging new technology which can improve data quality. Because such items as depth imaging, borehole seismic, 4-D and marine 3-component recording were mentioned in the May 1996 issue of World Oil, they are not discussed again here. However, these technologies will also play some role in the deepwater seismic activities. What is covered in this paper are somemore » new considerations for: (1) longer data records needed in deeper water, (2) some pros and cons of very long steamer use, and (3) two new commercial systems for quantifying data quality.« less
Probabilistic Seismic Hazard Assessment for Iraq
Onur, Tuna; Gok, Rengin; Abdulnaby, Wathiq
Probabilistic Seismic Hazard Assessments (PSHA) form the basis for most contemporary seismic provisions in building codes around the world. The current building code of Iraq was published in 1997. An update to this edition is in the process of being released. However, there are no national PSHA studies in Iraq for the new building code to refer to for seismic loading in terms of spectral accelerations. As an interim solution, the new draft building code was considering to refer to PSHA results produced in the late 1990s as part of the Global Seismic Hazard Assessment Program (GSHAP; Giardini et al.,more » 1999). However these results are: a) more than 15 years outdated, b) PGA-based only, necessitating rough conversion factors to calculate spectral accelerations at 0.3s and 1.0s for seismic design, and c) at a probability level of 10% chance of exceedance in 50 years, not the 2% that the building code requires. Hence there is a pressing need for a new, updated PSHA for Iraq.« less
EnviroAtlas - Bird National Biodiversity Ecosystem Services Metrics by 12-digit HUC for the Conterminous United States
This dataset was produced by a joint effort of New Mexico State University (NMSU), the U.S. Environmental Protection Agency (EPA), and the U.S. Geological Survey (USGS) to support research and online mapping activities related to EnviroAtlas. Ecosystem services, i.e., services provided to humans from ecological systems, have become a key issue of this century in resource management, conservation planning, and environmental decision analysis. Mapping and quantifying ecosystem services have become strategic national interests for integrating ecology with economics to help understand the effects of human policies and actions and their subsequent impacts on both ecosystem function and human well-being. Some aspects of biodiversity are valued by humans in varied ways, and thus are important to include in any assessment that seeks to identify and quantify the benefits of ecosystems to humans. Some biodiversity metrics clearly reflect ecosystem services (e.g., abundance and diversity of harvestable species), whereas others may reflect indirect and difficult to quantify relationships to services (e.g., relevance of species diversity to ecosystem resilience, or cultural and aesthetic values). Wildlife habitat has been modeled at broad spatial scales and can be used to map a number of biodiversity metrics. We map 15 biodiversity metrics reflecting ecosystem services or other aspects of biodiversity for bird species. Metrics include all bird species richness, lists identif
Western Rainier Seismic Zone Airborne Laser Swath Mapping
Harding, David J.; Haugerud, Ralph A.; Johnson, Samuel Y.; Scott, Kevin M.; Weaver, Craig S.; Martinez, Diana M.; Zeigler, John C.; Latypov, Damir
Airborne laser swath mapping (ALSM) of the Puget Lowland conducted by TerraPoint LLC for the Purget Sound Lidar Concortium (PSLC), has been successful in revealing Holocene fault scarps and lendsliders hidden beneath the dense, temperate rain forest cover and in quantifying shoreline terrace uplift. Expanding the PSLC efforts, NASA-USGS collaboration is now focusing on topographic mapping of seismogenic zones adjacent to volcanois in the western Cascades range in order to assess the presence of active faulting and tectonic deformation, better define the extend of lahars and understand their flow processes, and characterize landslide occurrence. Mapping of the western Rainier zone (WRZ) was conducted by TerraPoint in late 2002, after leaf fall and before snow accumulation. The WRZ is a NNW-trending, approx. 30 km-long zone of seismicity west of Mount Rainier National Park. The Puget Lowland ALSM methods were modified to accommodate challenges posed by the steep, high relief terrian. The laser data, acquired with a density of approx. 2 pulses /sq m, was filtered to identify returns from the ground from which a bare Earth digital elevation model (DEM) was produced with a grid size of 1.8 m. The RMS elevation accuracy of the DEM in flat, unvegetated areas is approx. 10cm based on consistency between overlapping flight swaths and comparisons to ground control points. The resulting DEM substantially improves upon Shuttle Radar Topography Mission and USGS photogrammetric mapping. For example, the DEM defines the size and spatial distribution of flood erratics left by the Electron lahar and of megaclasts within the Round Pass lahar, important for characterizing the lahar hydraulics. A previously unknown lateral levee on the Round Pass lahar is also revealed. In addition, to illustrating geomorfic feature within the WRZ, future plans for laser mapping of the Saint Helens and Darrington seismic zones will be described.
Global Seismic Monitoring: Past, Present, and Future
Zoback, M.; Benz, H.; Oppenheimer, D.
Global seismological observations began in April 1889 when an earthquake in Tokyo, Japan was accurately recorded in Germany on two different horizontal pendulum instruments. However, modern global observational seismology really began 46 years ago when the 120-station World Wide Standard Seismograph Network was installed by the US to monitor underground nuclear tests and earthquakes using well-calibrated short- and long- period stations. At the same time rapid advances in computing technology enabled researchers to begin sophisticated analysis of the increasing amount of seismic data, which led to better understanding of earthquake source properties and their use in establishing plate tectonics. Today, global seismic networks are operated by German (Geophon), France (Geoscope), the United States (Global Seismograph Network) and the International Monitoring System. Presently, the Federation of Digital Seismograph Networks registers more than 1,000 broadband stations world-wide, a small percentage of the total number of digital seismic stations around the world. Following the devastating Kobe, Japan and Northridge, California earthquakes, Japan and the US have led the world in the integration of existing seismic sensor systems (weak and strong motion) into development of near-real-time, post-earthquake response products like ShakeMap, detailing the spatial distribution of strong shaking. Future challenges include expanding real-time integration of both seismic and geodetic sensor systems to produce early warning of strong shaking, rapid source determination, as well as near-realtime post- earthquake damage assessment. Seismic network data, hydro-acoustic arrays, deep water tide gauges, and satellite imagery of wave propagation should be integrated in real-time to provide input for hydrodynamic modeling yielding the distribution, timing and size of tsunamis runup--which would then be available instantly on the web, e.g. in a Google Earth format. Dense arrays of strong
Landscape unit based digital elevation model development for the freshwater wetlands within the Arthur C. Marshall Loxahatchee National Wildlife Refuge, Southeastern Florida
Xie, Zhixiao; Liu, Zhongwei; Jones, John W.; Higer, Aaron L.; Telis, Pamela A.
The hydrologic regime is a critical limiting factor in the delicate ecosystem of the greater Everglades freshwater wetlands in south Florida that has been severely altered by management activities in the past several decades. "Getting the water right" is regarded as the key to successful restoration of this unique wetland ecosystem. An essential component to represent and model its hydrologic regime, specifically water depth, is an accurate ground Digital Elevation Model (DEM). The Everglades Depth Estimation Network (EDEN) supplies important hydrologic data, and its products (including a ground DEM) have been well received by scientists and resource managers involved in Everglades restoration. This study improves the EDEN DEMs of the Loxahatchee National Wildlife Refuge, also known as Water Conservation Area 1 (WCA1), by adopting a landscape unit (LU) based interpolation approach. The study first filtered the input elevation data based on newly available vegetation data, and then created a separate geostatistical model (universal kriging) for each LU. The resultant DEMs have encouraging cross-validation and validation results, especially since the validation is based on an independent elevation dataset (derived by subtracting water depth measurements from EDEN water surface elevations). The DEM product of this study will directly benefit hydrologic and ecological studies as well as restoration efforts. The study will also be valuable for a broad range of wetland studies.
The Caucasus Seismic Network (CNET): Seismic Structure of the Greater and Lesser Caucasus
Sandvol, E. A.; Mackey, K. G.; Nabelek, J.; Yetermishli, G.; Godoladze, T.; Babayan, H.; Malovichko, A.
The Greater Caucasus are a portion of the Alpine-Himalayan mountain belt that has undergone rapid uplift in the past 5 million years, thus serving as a unique natural laboratory to study the early stages of orogenesis. Relatively lower resolution seismic velocity models of this region show contradictory lateral variability. Furthermore, recent waveform modeling of seismograms has clearly demonstrated the presence of deep earthquakes (with a maximum hypocentral depth of 175 km) below the Greater Caucasus. The region has been largely unexplored in terms of the detailed uppermost mantle and crustal seismic structure due in part to the disparate data sets that have not yet been merged as well as key portions being sparsely instrumented. We have established collaborative agreements across the region. Building on these agreements we recently deployed a major multi-national seismic array across the Greater Caucasus to address fundamental questions about the nature of continental deformation in this poorly understood region. Our seismic array has two components: (1) a grid of stations spanning the entire Caucasus and (2) two seismic transects consisting of stations spaced at distances of less than 10 km that cross the Greater Caucasus. In addition to the temporary stations, we are working to integrate data from the national networks to produce high resolution images of the seismic structure. Using data from over 106 new seismic stations in Azerbaijan, Armenia, Russia, and Georgia, we hope to gain a better understanding of the recent uplift ( 5 Ma) of the Greater Caucasus and the nature of seismogenic deformation in the region.
New Seismic Monitoring Station at Mohawk Ridge, Valles Caldera
Roberts, Peter Morse
Two new broadband digital seismic stations were installed in the Valles Caldera in 2011 and 2012. The first is located on the summit of Cerros del Abrigo (station code CDAB) and the second is located on the flanks of San Antonio Mountain (station code SAMT). Seismic monitoring stations in the caldera serve multiple purposes. These stations augment and expand the current coverage of the Los Alamos Seismic Network (LASN), which is operated to support seismic and volcanic hazards studies for LANL and northern New Mexico (Figure 1). They also provide unique continuous seismic data within the caldera that can bemore » used for scientific studies of the caldera’s substructure and detection of very small seismic signals that may indicate changes in the current and evolving state of remnant magma that is known to exist beneath the caldera. Since the installation of CDAB and SAMT, several very small earthquakes have already been detected near San Antonio Mountain just west of SAMT (Figure 2). These are the first events to be seen in that area. Caldera stations also improve the detection and epicenter determination quality for larger local earthquakes on the Pajarito Fault System east of the Preserve and the Nacimiento Uplift to the west. These larger earthquakes are a concern to LANL Seismic Hazards assessments and seismic monitoring of the Los Alamos region, including the VCNP, is a DOE requirement. Currently the next closest seismic stations to the caldera are on Pipeline Road (PPR) just west of Los Alamos, and Peralta Ridge (PER) south of the caldera. There is no station coverage near the resurgent dome, Redondo Peak, in the center of the caldera. Filling this “hole� is the highest priority for the next new LASN station. We propose to install this station in 2018 on Mohawk Ridge just east of Redondito, in the same area already occupied by other scientific installations, such as the MCON flux tower operated by UNM.« less
United States National seismograph network
Masse, R.P.; Filson, J.R.; Murphy, A.
The USGS National Earthquake Information Center (NEIC) has planned and is developing a broadband digital seismograph network for the United States. The network will consist of approximately 150 seismograph stations distributed across the contiguous 48 states and across Alaska, Hawaii, Puerto Rico and the Virgin Islands. Data transmission will be via two-way satellite telemetry from the network sites to a central recording facility at the NEIC in Golden, Colorado. The design goal for the network is the on-scale recording by at least five well-distributed stations of any seismic event of magnitude 2.5 or greater in all areas of the United States except possibly part of Alaska. All event data from the network will be distributed to the scientific community on compact disc with read-only memory (CD-ROM). ?? 1989.
Preliminary consideration on the seismic actions recorded during the 2016 Central Italy seismic sequence
Carlo Ponzo, Felice; Ditommaso, Rocco; Nigro, Antonella; Nigro, Domenico S.; Iacovino, Chiara
After the Mw 6.0 mainshock of August 24, 2016 at 03.36 a.m. (local time), with the epicenter located between the towns of Accumoli (province of Rieti), Amatrice (province of Rieti) and Arquata del Tronto (province of Ascoli Piceno), several activities were started in order to perform some preliminary evaluations on the characteristics of the recent seismic sequence in the areas affected by the earthquake. Ambient vibration acquisitions have been performed using two three-directional velocimetric synchronized stations, with a natural frequency equal to 0.5Hz and a digitizer resolution of equal to 24bit. The activities are continuing after the events of the seismic sequence of October 26 and October 30, 2016. In this paper, in order to compare recorded and code provision values in terms of peak (PGA, PGV and PGD), spectral and integral (Housner Intensity) seismic parameters, several preliminary analyses have been performed on accelerometric time-histories acquired by three near fault station of the RAN (Italian Accelerometric Network): Amatrice station (station code AMT), Norcia station (station code NRC) and Castelsantangelo sul Nera station (station code CNE). Several comparisons between the elastic response spectra derived from accelerometric recordings and the elastic demand spectra provided by the Italian seismic code (NTC 2008) have been performed. Preliminary results retrieved from these analyses highlight several apparent difference between experimental data and conventional code provision. Then, the ongoing seismic sequence appears compatible with the historical seismicity in terms of integral parameters, but not in terms of peak and spectral values. It seems appropriate to reconsider the necessity to revise the simplified design approach based on the conventional spectral values.

Assessing the seismic risk potential of South America
Jaiswal, Kishor; Petersen, Mark D.; Harmsen, Stephen; Smoczyk, Gregory M.
We present here a simplified approach to quantifying regional seismic risk. The seismic risk for a given region can be inferred in terms of average annual loss (AAL) that represents long-term value of earthquake losses in any one year caused from a long-term seismic hazard. The AAL are commonly measured in the form of earthquake shaking-induced deaths, direct economic impacts or indirect losses caused due to loss of functionality. In the context of South American subcontinent, the analysis makes use of readily available public data on seismicity, population exposure, and the hazard and vulnerability models for the region. The seismic hazard model was derived using available seismic catalogs, fault databases, and the hazard methodologies that are analogous to the U.S. Geological Survey’s national seismic hazard mapping process. The Prompt Assessment of Global Earthquakes for Response (PAGER) system’s direct empirical vulnerability functions in terms of fatality and economic impact were used for performing exposure and risk analyses. The broad findings presented and the risk maps produced herein are preliminary, yet they do offer important insights into the underlying zones of high and low seismic risks in the South American subcontinent. A more detailed analysis of risk may be warranted by engaging local experts, especially in some of the high risk zones identified through the present investigation.
OGS improvements in 2012 in running the Northeastern Italy Seismic Network: the Ferrara VBB borehole seismic station
Pesaresi, Damiano; Romanelli, Marco; Barnaba, Carla; Bragato, Pier Luigi; Durì, Giorgio
The Centro di Ricerche Sismologiche (CRS, Seismological Research Center) of the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS, Italian National Institute for Oceanography and Experimental Geophysics) in Udine (Italy) after the strong earthquake of magnitude M=6.4 occurred in 1976 in the Italian Friuli-Venezia Giulia region, started to operate the Northeastern Italy Seismic Network: it currently consists of 17 very sensitive broad band and 18 simpler short period seismic stations, all telemetered to and acquired in real time at the OGS-CRS data center in Udine. Real time data exchange agreements in place with other Italian, Slovenian, Austrian and Swiss seismological institutes lead to a total number of about 100 seismic stations acquired in real time, which makes the OGS the reference institute for seismic monitoring of Northeastern Italy. The southwestern edge of the OGS seismic network stands on the Po alluvial basin: earthquake localization and characterization in this area is affected by the presence of soft alluvial deposits. OGS ha already experience in running a local seismic network in high noise conditions making use of borehole installations in the case of the micro-seismicity monitoring of a local gas storage site for a private company. Following the ML=5.9 earthquake that struck the Emilia region around Ferrara in Northern Italy on May 20, 2012 at 02:03:53 UTC, a cooperation of Istituto Nazionale di Geofisica e Vulcanologia, OGS, the Comune di Ferrara and the University of Ferrara lead to the reinstallation of a previously existing very broad band (VBB) borehole seismic station in Ferrara. The aim of the OGS intervention was on one hand to extend its real time seismic monitoring capabilities toward South-West, including Ferrara and its surroundings, and on the other hand to evaluate the seismic response at the site. We will describe improvements in running the Northeastern Italy Seismic Network, including details of the Ferrara VBB
Toward uniform probabilistic seismic hazard assessments for Southeast Asia
Chan, C. H.; Wang, Y.; Shi, X.; Ornthammarath, T.; Warnitchai, P.; Kosuwan, S.; Thant, M.; Nguyen, P. H.; Nguyen, L. M.; Solidum, R., Jr.; Irsyam, M.; Hidayati, S.; Sieh, K.
Although most Southeast Asian countries have seismic hazard maps, various methodologies and quality result in appreciable mismatches at national boundaries. We aim to conduct a uniform assessment across the region by through standardized earthquake and fault databases, ground-shaking scenarios, and regional hazard maps. Our earthquake database contains earthquake parameters obtained from global and national seismic networks, harmonized by removal of duplicate events and the use of moment magnitude. Our active-fault database includes fault parameters from previous studies and from the databases implemented for national seismic hazard maps. Another crucial input for seismic hazard assessment is proper evaluation of ground-shaking attenuation. Since few ground-motion prediction equations (GMPEs) have used local observations from this region, we evaluated attenuation by comparison of instrumental observations and felt intensities for recent earthquakes with predicted ground shaking from published GMPEs. We then utilize the best-fitting GMPEs and site conditions into our seismic hazard assessments. Based on the database and proper GMPEs, we have constructed regional probabilistic seismic hazard maps. The assessment shows highest seismic hazard levels near those faults with high slip rates, including the Sagaing Fault in central Myanmar, the Sumatran Fault in Sumatra, the Palu-Koro, Matano and Lawanopo Faults in Sulawesi, and the Philippine Fault across several islands of the Philippines. In addition, our assessment demonstrates the important fact that regions with low earthquake probability may well have a higher aggregate probability of future earthquakes, since they encompass much larger areas than the areas of high probability. The significant irony then is that in areas of low to moderate probability, where building codes are usually to provide less seismic resilience, seismic risk is likely to be greater.

Bayesian identification of multiple seismic change points and varying seismic rates caused by induced seismicity
Montoya-Noguera, Silvana; Wang, Yu
The Central and Eastern United States (CEUS) has experienced an abnormal increase in seismic activity, which is believed to be related to anthropogenic activities. The U.S. Geological Survey has acknowledged this situation and developed the CEUS 2016 1 year seismic hazard model using the catalog of 2015 by assuming stationary seismicity in that period. However, due to the nonstationary nature of induced seismicity, it is essential to identify change points for accurate probabilistic seismic hazard analysis (PSHA). We present a Bayesian procedure to identify the most probable change points in seismicity and define their respective seismic rates. It uses prior distributions in agreement with conventional PSHA and updates them with recent data to identify seismicity changes. It can determine the change points in a regional scale and may incorporate different types of information in an objective manner. It is first successfully tested with simulated data, and then it is used to evaluate Oklahoma's regional seismicity.
Landslide seismic magnitude
Lin, C. H.; Jan, J. C.; Pu, H. C.; Tu, Y.; Chen, C. C.; Wu, Y. M.
Landslides have become one of the most deadly natural disasters on earth, not only due to a significant increase in extreme climate change caused by global warming, but also rapid economic development in topographic relief areas. How to detect landslides using a real-time system has become an important question for reducing possible landslide impacts on human society. However, traditional detection of landslides, either through direct surveys in the field or remote sensing images obtained via aircraft or satellites, is highly time consuming. Here we analyze very long period seismic signals (20-50 s) generated by large landslides such as Typhoon Morakot, which passed though Taiwan in August 2009. In addition to successfully locating 109 large landslides, we define landslide seismic magnitude based on an empirical formula: Lm = log � (A) + 0.55 log � (Δ) + 2.44, where A is the maximum displacement (μm) recorded at one seismic station and Δ is its distance (km) from the landslide. We conclude that both the location and seismic magnitude of large landslides can be rapidly estimated from broadband seismic networks for both academic and applied purposes, similar to earthquake monitoring. We suggest a real-time algorithm be set up for routine monitoring of landslides in places where they pose a frequent threat.
Distribution and arrest of vertical through-going joints in a seismic-scale carbonate platform exposure (Sorrento peninsula, Italy): insights from integrating field survey and digital outcrop model
Corradetti, A.; Tavani, S.; Parente, M.; Iannace, A.; Vinci, F.; Pirmez, C.; Torrieri, S.; Giorgioni, M.; Pignalosa, A.; Mazzoli, S.
Through-going joints cutting across beds are often invoked to match large-scale permeability patterns in tight carbonate reservoirs. However, despite the importance of these structures for fluid flow, only few field studies focused on the understanding and estimation of through-going joint dimensional parameters, including spacing and vertical extent in relation to stratigraphy. Recent improvements in the construction of digital models of outcrops can greatly help to overcome many logistic issues, favouring the evaluation of relationships between jointing and stratigraphy at the reservoir scale. In this study, we present the results obtained from integrating field measurements with a digital outcrop model of a carbonate platform reservoir analogue in the Sorrento peninsula (Italy). The outcrop consists of a nearly vertical cliff exposing a monocline of alternating gently-dipping shallow-water limestones and dolostones, crossed by several vertical joints of different size. This study allowed us to define how major through-going joints pass across thick beds (bed thickness > 30 cm), while they arrest against packages made of thinly stratified layers. In essence, through-going joints arrest on "weak" levels, consisting of thinly bedded layers interposed between packages made of thick beds, in the same manner as bed-confined joints arrest on less competent interlayers.

The monitoring systems in the Bed Tower and Spinal Cord Injury buildings combine sensing technologies with an on-site computer to capture and analyze seismic performance of buildings in near-real time.
Urban Seismic Hazard Mapping for Memphis, Shelby County, Tennessee
Gomberg, Joan
Earthquakes cannot be predicted, but scientists can forecast how strongly the ground is likely to shake as a result of an earthquake. Seismic hazard maps provide one way of conveying such forecasts. The U.S. Geological Survey (USGS), which produces seismic hazard maps for the Nation, is now engaged in developing more detailed maps for vulnerable urban areas. The first set of these maps is now available for Memphis, Tennessee.

Controllable seismic source
Gomez, Antonio; DeRego, Paul Jeffrey; Ferrell, Patrick Andrew; Thom, Robert Anthony; Trujillo, Joshua J.; Herridge, Brian
An apparatus for generating seismic waves includes a housing, a strike surface within the housing, and a hammer movably disposed within the housing. An actuator induces a striking motion in the hammer such that the hammer impacts the strike surface as part of the striking motion. The actuator is selectively adjustable to change characteristics of the striking motion and characteristics of seismic waves generated by the impact. The hammer may be modified to change the physical characteristics of the hammer, thereby changing characteristics of seismic waves generated by the hammer. The hammer may be disposed within a removable shock cavity, and the apparatus may include two hammers and two shock cavities positioned symmetrically about a center of the apparatus.

Construction and development of IGP DMC of China National Seismological Network
Zheng, X.; Zheng, J.; Lin, P.; Yao, Z.; Liang, J.
In 2003, CEA (China Earthquake Administration) commenced the construction of China Digital Seismological Observation Network. By the end of 2007, a new-generation digital seismological observation system had been established, which consists of 1 National Seismic Network, 32 regional seismic networks, 2 small-aperture seismic arrays, 6 volcano monitoring networks and 19 mobile seismic networks, as well as CENC (China Earthquake Network Center) DMC (Data Management Centre) and IGP (Institute of Geophysics) DMC. Since then, the seismological observation system of China has completely entered a digital time. For operational, data backup and data security considerations, the DMC at the Institute of Geophysics (IGP), CEA was established at the end of 2007. IGP DMC now receives and archives waveform data from more than 1000 permanent seismic stations around China in real-time. After the great Wenchuan and Yushu earthquakes, the real-time waveform data from 56 and 8 portable seismic stations deployed in the aftershock area are added to IGP DMC. The technical system of IGP DMC is designed to conduct data management, processing and service through the network of CEA. We developed and integrated a hardware system with high-performance servers, large-capacity disc arrays, tape library and other facilities, as well as software packages for real-time waveform data receiving, storage, quality control, processing and service. Considering the demands from researchers for large quantities of seismic event waveform data, IGP DMC adopts an innovative "user order" method to extract event waveform data. Users can specify seismic stations, epicenter distance and record length. In a short period of 3 years, IGP DMC has supplied about 350 Terabytes waveform data to over 200 researches of more than 40 academic institutions. According to incomplete statistics, over 40 papers have been published in professional journals, in which 30 papers were indexed by SCI. Now, IGP DMC has become an
Quake warnings, seismic culture
Allen, Richard M.; Cochran, Elizabeth S.; Huggins, Tom; Miles, Scott; Otegui, Diego
Since 1990, nearly one million people have died from the impacts of earthquakes. Reducing those impacts requires building a local seismic culture in which residents are aware of earthquake risks and value efforts to mitigate harm. Such efforts include earthquake early warning (EEW) systems that provide seconds to minutes notice of pending shaking. Recent events in Mexico provide an opportunity to assess performance and perception of an EEW system and highlight areas for further improvement. We have learned that EEW systems, even imperfect ones, can help people prepare for earthquakes and build local seismic culture, both beneficial in reducing earthquake-related losses.
Induced Seismicity Monitoring System
Taylor, S. R.; Jarpe, S.; Harben, P.
There are many seismological aspects associated with monitoring of permanent storage of carbon dioxide (CO2) in geologic formations. Many of these include monitoring underground gas migration through detailed tomographic studies of rock properties, integrity of the cap rock and micro seismicity with time. These types of studies require expensive deployments of surface and borehole sensors in the vicinity of the CO2 injection wells. Another problem that may exist in CO2 sequestration fields is the potential for damaging induced seismicity associated with fluid injection into the geologic reservoir. Seismic hazard monitoring in CO2 sequestration fields requires a seismic network over a spatially larger region possibly having stations in remote settings. Expensive observatory-grade seismic systems are not necessary for seismic hazard deployments or small-scale tomographic studies. Hazard monitoring requires accurate location of induced seismicity to magnitude levels only slightly less than that which can be felt at the surface (e.g. magnitude 1), and the frequencies of interest for tomographic analysis are ~1 Hz and greater. We have developed a seismo/acoustic smart sensor system that can achieve the goals necessary for induced seismicity monitoring in CO2 sequestration fields. The unit is inexpensive, lightweight, easy to deploy, can operate remotely under harsh conditions and features 9 channels of recording (currently 3C 4.5 Hz geophone, MEMS accelerometer and microphone). An on-board processor allows for satellite transmission of parameter data to a processing center. Continuous or event-detected data is kept on two removable flash SD cards of up to 64+ Gbytes each. If available, data can be transmitted via cell phone modem or picked up via site visits. Low-power consumption allows for autonomous operation using only a 10 watt solar panel and a gel-cell battery. The system has been successfully tested for long-term (> 6 months) remote operations over a wide range

Archive of Digitized Analog Boomer Seismic Reflection Data Collected from the Mississippi-Alabama-Florida Shelf During Cruises Onboard the R/V Kit Jones, June 1990 and July 1991
In June of 1990 and July of 1991, the U.S. Geological Survey (USGS) conducted geophysical surveys to investigate the shallow geologic framework of the Mississippi-Alabama-Florida shelf in the northern Gulf of Mexico, from Mississippi Sound to the Florida Panhandle. Work was done onboard the Mississippi Mineral Resources Institute R/V Kit Jones as part of a project to study coastal erosion and offshore sand resources. This report is part of a series to digitally archive the legacy analog data collected from the Mississippi-Alabama SHelf (MASH). The MASH data rescue project is a cooperative effort by the USGS and the Minerals Management Service (MMS). This report serves as an archive of high-resolution scanned Tagged Image File Format (TIFF) and Graphics Interchange Format (GIF) images of the original boomer paper records, navigation files, trackline maps, Geographic Information System (GIS) files, cruise logs, and formal Federal Geographic Data Committee (FGDC) metadata.

Puerto Rico Strong Motion Seismic Network
Huerta-Lopez, C. I.; MartÃnez-Cruzado, J. A.; MartÃnez-Pagan, J.; Santana-Torres, E. X.; Torres-O, D. M.
The Puerto Rico Strong Motion Seismic Network is currently in charge of the operation of: (i) free-field (ff) strong motion stations, (ii) instrumented structures (STR) (Dams, Bridges, Buildings), and (iii) the data acquisition/monitoring and analysis of earthquakes considered strong from the point of view of their intensity and magnitude. All these instruments are deployed in the Puerto Rico Island (PRI), US-, and British-Virgin Islands (BVI), and Dominican Republic (DR). The Puerto Rico Island and the Caribbean region have high potential to be affected by earthquakes that could be catastrophic for the area. The Puerto Rico Strong Motion Seismic Network (actually Puerto Rico Strong Motion Program, PRSMP) has grown since 1970's from 7 ff strong motion stations and one instrumented building with analog accelerographs to 111 ff strong motion stations and 16 instrumented buildings with digital accelerographs: PRI: 88 ff, 16 STR., DR: 13 ff, BVI: 5 ff, 2 STR collecting data via IP (internet), DU (telephone), and stand alone stations The current stage of the PRSMP seismic network, the analysis of moderate earthquakes that were recorded and/or occurred on the island, results of the intensity distribution of selected earthquakes, as well as results of dynamic parameter identification of some of the instrumented structures are here presented.
Back to the Future: Long-Term Seismic Archives Revisited
Waldhauser, F.; Schaff, D. P.
Archives of digital seismic data recorded by seismometer networks around the world have grown tremendously over the last several decades helped by the deployment of seismic stations and their continued operation within the framework of monitoring seismic activity. These archives typically consist of waveforms of seismic events and associated parametric data such as phase arrival time picks and the location of hypocenters. Catalogs of earthquake locations are fundamental data in seismology, and even in the Earth sciences in general. Yet, these locations have notoriously low spatial resolution because of errors in both the picks and the models commonly used to locate events one at a time. This limits their potential to address fundamental questions concerning the physics of earthquakes, the structure and composition of the Earth's interior, and the seismic hazards associated with active faults. We report on the comprehensive use of modern waveform cross-correlation based methodologies for high- resolution earthquake location - as applied to regional and global long-term seismic databases. By simultaneous re-analysis of two decades of the digital seismic archive of Northern California, reducing pick errors via cross-correlation and model errors via double-differencing, we achieve up to three orders of magnitude resolution improvement over existing hypocenter locations. The relocated events image networks of discrete faults at seismogenic depths across various tectonic settings that until now have been hidden in location uncertainties. Similar location improvements are obtained for earthquakes recorded at global networks by re- processing 40 years of parametric data from the ISC and corresponding waveforms archived at IRIS. Since our methods are scaleable and run on inexpensive Beowulf clusters, periodic re-analysis of entire archives may thus become a routine procedure to continuously improve resolution in existing catalogs. We demonstrate the role of seismic archives
Local magnitude calibration of the Hellenic Unified Seismic Network
Scordilis, E. M.; Kementzetzidou, D.; Papazachos, B. C.
A new relation is proposed for accurate determination of local magnitudes in Greece. This relation is based on a large number of synthetic Wood-Anderson (SWA) seismograms corresponding to 782 regional shallow earthquakes which occurred during the period 2007-2013 and recorded by 98 digital broad-band stations. These stations are installed and operated by the following: (a) the National Observatory of Athens (HL), (b) the Department of Geophysics of the Aristotle University of Thessaloniki (HT), (c) the Seismological Laboratory of the University of Athens (HA), and (d) the Seismological Laboratory of the Patras University (HP). The seismological networks of the above institutions constitute the recently (2004) established Hellenic Unified Seismic Network (HUSN). These records are used to calculate a refined geometrical spreading factor and an anelastic attenuation coefficient, representative for Greece and surrounding areas, proper for accurate calculation of local magnitudes in this region. Individual station corrections depending on the crustal structure variations in their vicinity and possible inconsistencies in instruments responses are also considered in order to further ameliorate magnitude estimation accuracy. Comparison of such calculated local magnitudes with corresponding original moment magnitudes, based on an independent dataset, revealed that these magnitude scales are equivalent for a wide range of values.
Updating Hawaii Seismicity Catalogs with Systematic Relocations and Subspace Detectors
Okubo, P.; Benz, H.; Matoza, R. S.; Thelen, W. A.
We continue the systematic relocation of seismicity recorded in Hawai`i by the United States Geological Survey's (USGS) Hawaiian Volcano Observatory (HVO), with interests in adding to the products derived from the relocated seismicity catalogs published by Matoza et al., (2013, 2014). Another goal of this effort is updating the systematically relocated HVO catalog since 2009, when earthquake cataloging at HVO was migrated to the USGS Advanced National Seismic System Quake Management Software (AQMS) systems. To complement the relocation analyses of the catalogs generated from traditional STA/LTA event-triggered and analyst-reviewed approaches, we are also experimenting with subspace detection of events at Kilauea as a means to augment AQMS procedures for cataloging seismicity to lower magnitudes and during episodes of elevated volcanic activity. Our earlier catalog relocations have demonstrated the ability to define correlated or repeating families of earthquakes and provide more detailed definition of seismogenic structures, as well as the capability for improved automatic identification of diverse volcanic seismic sources. Subspace detectors have been successfully applied to cataloging seismicity in situations of low seismic signal-to-noise and have significantly increased catalog sensitivity to lower magnitude thresholds. We anticipate similar improvements using event subspace detections and cataloging of volcanic seismicity that include improved discrimination among not only evolving earthquake sequences but also diverse volcanic seismic source processes.

Canadian Seismicity Catalogue - Western Canada
Mulder, T.
The first seismograph station in western Canada was installed in Victoria, BC, in 1898, under the Meteorological Service of Canada. By 1940, seismograph installations in Canada were amalgamated under the Dominion Observatory. The first short-period instruments were installed in western Canada in the early 1950's. The first digital instruments were installed in the mid-1970's. To date there are now 54 digital stations in western Canada that are routinely used in analysis as well as 2 paper-record stations. Detection ability has increased significantly over the past 20 years. Magnitude thresholds for locations vary over space and time reflecting seismicity levels, station distribution, and staffing levels. Currently the magnitude thresholds are (these do not necessarily equate to completeness levels): M=2.5-3.0 for western Canada; M=2.0 in the St Elias Mountains, YT, the northern Coast Mountains, BC, most of southern BC, and southwestern Alberta; M=1.0-1.5 in the Queen Charlotte Islands, southern Coast Mountains, and northern Vancouver Island; M=0.7-0.8 in southern Vancouver Island and the adjacent mainland. Events have been located with a variety of location programs over the years. A number of velocity models have been in use over time, currently resulting in a generic model for all of western Canada, and a model each for offshore, the Queen Charlotte Islands, and Vancouver Island. Recently purchased Antelope software will allow improved ability to maintain and possibly extend current magnitude thresholds as much of the daily analyst housekeeping tasks are decreased. Recent additions to the catalogue are regular computation of P-nodal and moment tensor solutions.
IMS Seismic and Infrasound Stations Instrumental Challenges
Starovoit, Y. O.; Dricker, I. G.; Marty, J.
The IMS seismic network is a set of monitoring facilities including 50 primary stations and 120 auxiliary stations. Besides the difference in the mode of data transmission to the IDC, technical specifications for seismographic equipment to be installed at both types of stations are essentially the same. The IMS infrasound network comprises 60 facilities with the requirement of continuous data transmission to IDC. The objective of this presentation is to report instrumental challenges associated with both seismic and infrasound technologies. In context of specifications for IMS seismic stations it was stressed that verification seismology is concerned with searching of reliable methods of signal detections at high frequencies. In the meantime MS/mb screening criteria between earthquakes and explosions relies on reliable detection of surface waves. The IMS seismic requirements for instrumental noise and operational range of data logger are defined as certain dB level below minimum background within the required frequency band from 0.02 to 16Hz. The type of sensors response is requested to be flat either in velocity or acceleration. The compliance with IMS specifications may thus introduce a challenging task when low-noise conditions have been recorded at the site. It means that as a station noise PSD approaches the NLNM it requires a high sensitive sensor to be connected to a quiet digitizer which may cause a quick system clip and waste of the available dynamic range. The experience has shown that hybrid frequency response of seismic sensors where combination of flat to velocity and flat to acceleration portions of the sensor frequency response may provide an optimal solution for utilization of the dynamic range and low digitizer noise floor. Vast efforts are also being undertaken and results achieved in the infrasound technology to standardize and optimize the response of the Wind-Noise Reduction System within the IMS infrasound passband from 0.02-4Hz and to deploy

Seismic Imaging of the Source Physics Experiment Site with the Large-N Seismic Array
Chen, T.; Snelson, C. M.; Mellors, R. J.
The Source Physics Experiment (SPE) consists of a series of chemical explosions at the Nevada National Security Site. The goal of SPE is to understand seismic wave generation and propagation from these explosions. To achieve this goal, we need an accurate geophysical model of the SPE site. A Large-N seismic array that was deployed at the SPE site during one of the chemical explosions (SPE-5) helps us construct high-resolution local geophysical model. The Large-N seismic array consists of 996 geophones, and covers an area of approximately 2 × 2.5 km. The array is located in the northern end of the Yucca Flat basin, at a transition from Climax Stock (granite) to Yucca Flat (alluvium). In addition to the SPE-5 explosion, the Large-N array also recorded 53 weight drops. Using the Large-N seismic array recordings, we perform body wave and surface wave velocity analysis, and obtain 3D seismic imaging of the SPE site for the top crust of approximately 1 km. The imaging results show clear variation of geophysical parameter with local geological structures, including heterogeneous weathering layer and various rock types. The results of this work are being incorporated in the larger 3D modeling effort of the SPE program to validate the predictive models developed for the site.
Deployment of the Oklahoma borehole seismic experiment
Harben, P.E.; Rock, D.W.
This paper discusses the Oklahoma borehole seismic experiment, currently in operation, set up by members of the Lawrence Livermore National Laboratory Treaty Verification Program and the Oklahoma Geophysical Observatory to determine deep-borehole seismic characteristics in geology typical of large regions in the Soviet Union. We evaluated and logged an existing 772-m deep borehole on the Observatory site by running caliper, cement bonding, casing inspection, and hole-deviation logs. Two Teledyne Geotech borehole-clamping seismometers were placed at various depths and spacings in the deep borehole. Currently, they are deployed at 727 and 730 m. A Teledyne Geotech shallow-borehole seismometer was mounted inmore » a 4.5-m hole, one meter from the deep borehole. The seismometers' system coherency were tested and found to be excellent to 35 Hz. We have recorded seismic noise, quarry blasts, regional earthquakes and teleseisms in the present configuration. We will begin a study of seismic noise and attenuation as a function of depth in the near future. 7 refs., 18 figs.« less
Seismic noise level variation in South Korea
Sheen, D.; Shin, J.
The variations of seismic background noise in South Korea have been investigated by means of power spectral analysis. The Korea Institute of Geoscience and Mineral Resources (KIGAM) and the Korea Meteorological Administation (KMA) have national wide seismic networks in South Korea, and, in the end of 2007, there are 30 broadband stations which have been operating for more than a year. In this study, we have estimated the power spectral density of seismic noise for 30 broadband stations from 2005 to 2007. Since we estimate PSDs from a large dataset of continuous waveform in this study, a robust PSD estimate of McNamara and Buland (2004) is used. In the frequency range 1-5 Hz, the diurnal variations of noise are observed at most of stations, which are especially larger at coastal stations and at insular than at inland. Some stations shows daily difference of diurnal variations, which represents that cultural activities contribute to the noise level of a station. The variation of number of triggered stations, however, shows that cultural noise has little influence on the detection capability of seismic network in South Korea. Seasonal variations are observed well in the range 0.1-0.5 Hz, while much less found in the frequency range 1-5 Hz. We observed that strong peaks in the range 0.1-0.5 Hz occur at the summer when Pacific typhoons are close to the Korean Peninsula.
Ambient seismic wave field
NISHIDA, Kiwamu
The ambient seismic wave field, also known as ambient noise, is excited by oceanic gravity waves primarily. This can be categorized as seismic hum (1–20 mHz), primary microseisms (0.02–0.1 Hz), and secondary microseisms (0.1–1 Hz). Below 20 mHz, pressure fluctuations of ocean infragravity waves reach the abyssal floor. Topographic coupling between seismic waves and ocean infragravity waves at the abyssal floor can explain the observed shear traction sources. Below 5 mHz, atmospheric disturbances may also contribute to this excitation. Excitation of primary microseisms can be attributed to topographic coupling between ocean swell and seismic waves on subtle undulation of continental shelves. Excitation of secondary microseisms can be attributed to non-linear forcing by standing ocean swell at the sea surface in both pelagic and coastal regions. Recent developments in source location based on body-wave microseisms enable us to estimate forcing quantitatively. For a comprehensive understanding, we must consider the solid Earth, the ocean, and the atmosphere as a coupled system. PMID:28769015

Lunar seismicity and tectonics
Lammlein, D. R.
Results are presented for an analysis of all moonquake data obtained by the Apollo seismic stations during the period from November 1969 to May 1974 and a preliminary analysis of critical data obtained in the interval from May 1974 to May 1975. More accurate locations are found for previously located moonquakes, and additional sources are located. Consideration is given to the sources of natural seismic signals, lunar seismic activity, moonquake periodicities, tidal periodicities in moonquake activity, hypocentral locations and occurrence characteristics of deep and shallow moonquakes, lunar tidal control over moonquakes, lunar tectonism, the locations of moonquake belts, and the dynamics of the lunar interior. It is concluded that: (1) moonquakes are distributed in several major belts of global extent that coincide with regions of the youngest and most intense volcanic and tectonic activity; (2) lunar tides control both the small quakes occurring at great depth and the larger quakes occurring near the surface; (3) the moon has a much thicker lithosphere than earth; (4) a single tectonic mechanism may account for all lunar seismic activity; and (5) lunar tidal stresses are an efficient triggering mechanism for moonquakes.
High Voltage Seismic Generator
Bogacz, Adrian; Pala, Damian; Knafel, Marcin
This contribution describes the preliminary result of annual cooperation of three student research groups from AGH UST in Krakow, Poland. The aim of this cooperation was to develop and construct a high voltage seismic wave generator. Constructed device uses a high-energy electrical discharge to generate seismic wave in ground. This type of device can be applied in several different methods of seismic measurement, but because of its limited power it is mainly dedicated for engineering geophysics. The source operates on a basic physical principles. The energy is stored in capacitor bank, which is charged by two stage low to high voltage converter. Stored energy is then released in very short time through high voltage thyristor in spark gap. The whole appliance is powered from li-ion battery and controlled by ATmega microcontroller. It is possible to construct larger and more powerful device. In this contribution the structure of device with technical specifications is resented. As a part of the investigation the prototype was built and series of experiments conducted. System parameter was measured, on this basis specification of elements for the final device were chosen. First stage of the project was successful. It was possible to efficiently generate seismic waves with constructed device. Then the field test was conducted. Spark gap wasplaced in shallowborehole(0.5 m) filled with salt water. Geophones were placed on the ground in straight line. The comparison of signal registered with hammer source and sparker source was made. The results of the test measurements are presented and discussed. Analysis of the collected data shows that characteristic of generated seismic signal is very promising, thus confirms possibility of practical application of the new high voltage generator. The biggest advantage of presented device after signal characteristics is its size which is 0.5 x 0.25 x 0.2 m and weight approximately 7 kg. This features with small li-ion battery makes
Background noise model development for seismic stations of KMA
Jeon, Youngsoo
The background noise recorded at seismometer is exist at any seismic signal due to the natural phenomena of the medium which the signal passed through. Reducing the seismic noise is very important to improve the data quality in seismic studies. But, the most important aspect of reducing seismic noise is to find the appropriate place before installing the seismometer. For this reason, NIMR(National Institution of Meteorological Researches) starts to develop a model of standard background noise for the broadband seismic stations of the KMA(Korea Meteorological Administration) using a continuous data set obtained from 13 broadband stations during the period of 2007 and 2008. We also developed the model using short period seismic data from 10 stations at the year of 2009. The method of Mcmara and Buland(2004) is applied to analyse background noise of Korean Peninsula. The fact that borehole seismometer records show low noise level at frequency range greater than 1 Hz compared with that of records at the surface indicate that the cultural noise of inland Korean Peninsula should be considered to process the seismic data set. Reducing Double Frequency peak also should be regarded because the Korean Peninsula surrounded by the seas from eastern, western and southern part. The development of KMA background model shows that the Peterson model(1993) is not applicable to fit the background noise signal generated from Korean Peninsula.
Seismic Noise Characterization in the Northern Mississippi Embayment
Wiley, S.; Deshon, H. R.; Boyd, O. S.
We present a study of seismic noise sources present within the northern Mississippi embayment near the New Madrid Seismic Zone (NMSZ). The northern embayment contains up to 1 km of unconsolidated coastal plain sediments overlying bedrock, making it an inherently noisy environment for seismic stations. The area is known to display high levels of cultural noise caused by agricultural activity, passing cars, trains, etc. We characterize continuous broadband seismic noise data recorded for the months of March through June 2009 at six stations operated by the Cooperative New Madrid Seismic Network. We looked at a single horizontal component of data during nighttime hours, defined as 6:15PM to 5:45AM Central Standard Time, which we determined to be the lowest amplitude period of noise for the region. Hourly median amplitudes were compared to daily average wind speeds downloaded from the National Oceanic and Atmospheric Administration. We find a correlation between time periods of increased noise and days with high wind speeds, suggesting that wind is likely a prevalent source of seismic noise in the area. The effects of wind on seismic recordings may result from wind induced tree root movement which causes ground motion to be recorded at the vaults located ~3m below ground. Automated studies utilizing the local network or the EarthScope Transportable Array, scheduled to arrive in the area in 2010-11, should expect to encounter wind induced noise fluctuations and must account for this in their analysis.
Archive of Digitized Analog Boomer and Minisparker Seismic Reflection Data Collected from the Alabama-Mississippi-Louisiana Shelf During Cruises Onboard the R/V Carancahua and R/V Gyre, April and July, 1981
In April and July of 1981, the U.S. Geological Survey (USGS) conducted geophysical surveys to investigate the shallow geologic framework of the Alabama-Mississippi-Louisiana Shelf in the northern Gulf of Mexico. Work was conducted onboard the Texas A&M University R/V Carancahua and the R/V Gyre to develop a geologic understanding of the study area and to locate potential hazards related to offshore oil and gas production. While the R/V Carancahua only collected boomer data, the R/V Gyre used a 400-Joule minisparker, 3.5-kilohertz (kHz) subbottom profiler, 12-kHz precision depth recorder, and two air guns. The authors selected the minisparker data set because, unlike with the boomer data, it provided the most complete record. This report is part of a series to digitally archive the legacy analog data collected from the Mississippi-Alabama SHelf (MASH). The MASH data rescue project is a cooperative effort by the USGS and the Minerals Management Service (MMS). This report serves as an archive of high-resolution scanned Tagged Image File Format (TIFF) and Graphics Interchange Format (GIF) images of the original boomer and minisparker paper records, navigation files, trackline maps, Geographic Information System (GIS) files, cruise logs, and formal Federal Geographic Data Committee (FGDC) metadata.
Understanding the Digital Gap Among US Adults With Disability: Cross-Sectional Analysis of the Health Information National Trends Survey 2013.
Kim, Eun Ji; Yuan, Yiyang; Liebschutz, Jane; Cabral, Howard; Kazis, Lewis
Disabilities affect more than 1 in 5 US adults, and those with disabilities face multiple barriers in accessing health care. A digital gap, defined as the disparity caused by differences in the ability to use advanced technologies, is assumed to be prevalent among individuals with disabilities. This study examined the associations between disability and use of information technology (IT) in obtaining health information and between trust factors and IT use. We hypothesized that compared to US adults without disabilities, those with disabilities are less likely to refer to the internet for health information, more likely to refer to a health care provider to obtain health information, and less likely to use IT to exchange medical information with a provider. Additionally, we hypothesized that trust factors, such as trust toward health information source and willingness to exchange health information, are associated with IT use. The primary database was the 2013 Health Information National Trends Survey 4 Cycle 3 (N=3185). Disability status, the primary study covariate, was based on 6 questions that encompassed a wide spectrum of conditions, including impairments in mobility, cognition, independent living, vision, hearing, and self-care. Study covariates included sociodemographic factors, respondents' trust toward the internet and provider as information sources, and willingness to exchange medical information via IT with providers. Study outcomes were the use of the internet as the primary health information source, use of health care providers as the primary health information source, and use of IT to exchange medical information with providers. We conducted multivariate logistic regressions to examine the association between disability and study outcomes controlling for study covariates. Multiple imputations with fully conditional specification were used to impute missing values. We found presence of any disability was associated with decreased odds (adjusted odds
A permanent seismic station beneath the Ocean Bottom
Harris, David; Cessaro, Robert K.; Duennebier, Fred K.; Byrne, David A.
The Hawaii Institute of Geophysics began development of the Ocean Subbottom Seisometer (OSS) system in 1978, and OSS systems were installed in four locations between 1979 and 1982. The OSS system is a permanent, deep ocean borehole seismic recording system composed of a borehole sensor package (tool), an electromechanical cable, recorder package, and recovery system. Installed near the bottom of a borehole (drilled by the D/V Glomar Challenger), the tool contains three orthogonal, 4.5-Hz geophones, two orthogonal tilt meters; and a temperature sensor. Signals from these sensors are multiplexed, digitized (with a floating point technique), and telemetered through approximately 10 km of electromechanical cable to a recorder package located near the ocean bottom. Electrical power for the tool is supplied from the recorder package. The digital seismic signals are demultiplexed, converted back to analog form, processed through an automatic gain control (AGC) circuit, and recorded along with a time code on magnetic tape cassettes in the recorder package. Data may be recorded continuously for up to two months in the self-contained recorder package. Data may also be recorded in real time (digital formal) during the installation and subsequent recorder package servicing. The recorder package is connected to a submerged recovery buoy by a length of bouyant polypropylene rope. The anchor on the recovery buoy is released by activating either of the acoustical command releases. The polypropylene rope may also be seized with a grappling hook to effect recovery. The recorder package may be repeatedly serviced as long as the tool remains functional A wide range of data has been recovered from the OSS system. Recovered analog records include signals from natural seismic sources such as earthquakes (teleseismic and local), man-made seismic sources such as refraction seismic shooting (explosives and air cannons), and nuclear tests. Lengthy continuous recording has permitted analysis
Evaluation of seismic design spectrum based on UHS implementing fourth-generation seismic hazard maps of Canada
Ahmed, Ali; Hasan, Rafiq; Pekau, Oscar A.
Two recent developments have come into the forefront with reference to updating the seismic design provisions for codes: (1) publication of new seismic hazard maps for Canada by the Geological Survey of Canada, and (2) emergence of the concept of new spectral format outdating the conventional standardized spectral format. The fourth -generation seismic hazard maps are based on enriched seismic data, enhanced knowledge of regional seismicity and improved seismic hazard modeling techniques. Therefore, the new maps are more accurate and need to incorporate into the Canadian Highway Bridge Design Code (CHBDC) for its next edition similar to its building counterpart National Building Code of Canada (NBCC). In fact, the code writers expressed similar intentions with comments in the commentary of CHBCD 2006. During the process of updating codes, NBCC, and AASHTO Guide Specifications for LRFD Seismic Bridge Design, American Association of State Highway and Transportation Officials, Washington (2009) lowered the probability level from 10 to 2% and 10 to 5%, respectively. This study has brought five sets of hazard maps corresponding to 2%, 5% and 10% probability of exceedance in 50 years developed by the GSC under investigation. To have a sound statistical inference, 389 Canadian cities are selected. This study shows the implications of the changes of new hazard maps on the design process (i.e., extent of magnification or reduction of the design forces).
Digital Imaging is the computer processed numerical representation of physical images. Enhancement of images results in easier interpretation. Quantitative digital image analysis by Perceptive Scientific Instruments, locates objects within an image and measures them to extract quantitative information. Applications are CAT scanners, radiography, microscopy in medicine as well as various industrial and manufacturing uses. The PSICOM 327 performs all digital image analysis functions. It is based on Jet Propulsion Laboratory technology, is accurate and cost efficient.
Sobotka, Werner K.
Digital printing is described as a tool to replace conventional printing machines completely. Still this goal was not reached until now with any of the digital printing technologies to be described in the paper. Productivity and costs are still the main parameters and are not really solved until now. Quality in digital printing is no problem anymore. Definition of digital printing is to transfer digital datas directly on the paper surface. This step can be carried out directly or with the use of an intermediate image carrier. Keywords in digital printing are: computer- to-press; erasable image carrier; image carrier with memory. Digital printing is also the logical development of the new digital area as it is pointed out in Nicholas Negropotes book 'Being Digital' and also the answer to networking and Internet technologies. Creating images text and color in one country and publishing the datas in another country or continent is the main advantage. Printing on demand another big advantage and last but not least personalization the last big advantage. Costs and being able to coop with this new world of prepress technology is the biggest disadvantage. Therefore the very optimistic growth rates for the next few years are really nonexistent. The development of complete new markets is too slow and the replacing of old markets is too small.
Probabilistic Seismic Hazard Analysis for Georgia
Tsereteli, N. S.; Varazanashvili, O.; Sharia, T.; Arabidze, V.; Tibaldi, A.; Bonali, F. L. L.; Russo, E.; Pasquaré Mariotto, F.
Nowadays, seismic hazard studies are developed in terms of the calculation of Peak Ground Acceleration (PGA), Spectral Acceleration (SA), Peak Ground Velocity (PGV) and other recorded parameters. In the frame of EMME project PSH were calculated for Georgia using GMPE based on selection criteria. In the frame of Project N 216758 (supported by Shota Rustaveli National Science Foundation (SRNF)) PSH maps were estimated using hybrid- empirical ground motion prediction equation developed for Georgia. Due to the paucity of seismically recorded information, in this work we focused our research on a more robust dataset related to macroseismic data,and attempted to calculate the probabilistic seismic hazard directly in terms of macroseismicintensity. For this reason, we started calculating new intensity prediction equations (IPEs)for Georgia taking into account different sets, belonging to the same new database, as well as distances from the seismic source.With respect to the seismic source, in order to improve the quality of the results, we have also hypothesized the size of faults from empirical relations, and calculated new IPEs also by considering Joyner-Boore and rupture distances in addition to epicentral and hypocentral distances. Finally, site conditions have been included as variables for IPEs calculation Regarding the database, we used a brand new revised set of macroseismic data and instrumental records for the significant earthquakes that struck Georgia between 1900 and 2002.Particularly, a large amount of research and documents related to macroseismic effects of individual earthquakes, stored in the archives of the Institute of Geophysics, were used as sources for the new macroseismic data. The latter are reported in the Medvedev-Sponheuer-Karnikmacroseismic scale (MSK64). For each earthquake the magnitude, the focal depth and the epicenter location are also reported. An online version of the database, with therelated metadata,has been produced for the 69
Digital modeling of radioactive and chemical waste transport in the aquifer underlying the Snake River Plain at the National Reactor Testing Station, Idaho
Robertson, J.B.
Industrial and low-level radioactive liquid wastes at the National Reactor Testing Station (NRTS) in Idaho have been disposed to the Snake River Plain aquifer since 1952. Monitoring studies have indicated that tritium and chloride have dispersed over a 15-square mile (39-square kilometer) area of the aquifer in low but detectable concentrations and have only migrated as far as 5 miles (8 kilometers) downgradient from discharge points. The movement of cationic waste solutes, particularly 90Sr and 137Cs, has been significantly retarded due to sorption phenomena, principally ion exchange. 137Cs has shown no detectable migration in the aquifer and 90Sr has migrated only about 1.5 miles (2 kilometers) from the Idaho Chemical Processing Plant (ICPP) discharge well, and is detectable over an area of only 1.5 square miles ( 4 square kilometers) of the aquifer. Digital modeling techniques have been applied successfully to the analysis of the complex waste-transport system by utilizing numerical solution of the coupled equations of groundwater motion and mass transport. The model includes the effects of convective transport, flow divergence, two-dimensional hydraulic dispersion, radioactive decay, and reversible linear sorption. The hydraulic phase of the model uses the iterative, alternating direction, implicit finite-difference scheme to solve the groundwater flow equations, while the waste-transport phase uses a modified method of characteristics to solve the solute transport equations simulated by the model. The modeling results indicate that hydraulic dispersion (especially transverse) is a much more significant influence than previously suggested by earlier studies. The model has been used to estimate future waste migration patterns for varied assumed hydrological and waste conditions up through the year 2000. The hydraulic effects of recharge from the Big Lost River have an important (but not predominant) influence on the simulated future migration patterns. For the
Small Arrays for Seismic Intruder Detections: A Simulation Based Experiment
Pitarka, A.
Seismic sensors such as geophones and fiber optic have been increasingly recognized as promising technologies for intelligence surveillance, including intruder detection and perimeter defense systems. Geophone arrays have the capability to provide cost effective intruder detection in protecting assets with large perimeters. A seismic intruder detection system uses one or multiple arrays of geophones design to record seismic signals from footsteps and ground vehicles. Using a series of real-time signal processing algorithms the system detects, classify and monitors the intruder's movement. We have carried out numerical experiments to demonstrate the capability of a seismic array to detect moving targets that generate seismic signals. The seismic source is modeled as a vertical force acting on the ground that generates continuous impulsive seismic signals with different predominant frequencies. Frequency-wave number analysis of the synthetic array data was used to demonstrate the array's capability at accurately determining intruder's movement direction. The performance of the array was also analyzed in detecting two or more objects moving at the same time. One of the drawbacks of using a single array system is its inefficiency at detecting seismic signals deflected by large underground objects. We will show simulation results of the effect of an underground concrete block at shielding the seismic signal coming from an intruder. Based on simulations we found that multiple small arrays can greatly improve the system's detection capability in the presence of underground structures. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344
ANZA Seismic Network- From Monitoring to Science
Vernon, F.; Eakin, J.; Martynov, V.; Newman, R.; Offield, G.; Hindley, A.; Astiz, L.
The ANZA Seismic Network (http:eqinfo.ucsd.edu) utilizes broadband and strong motion sensors with 24-bit dataloggers combined with real-time telemetry to monitor local and regional seismicity in southernmost California. The ANZA network provides real-time data to the IRIS DMC, California Integrated Seismic Network (CISN), other regional networks, and the Advanced National Seismic System (ANSS), in addition to providing near real-time information and monitoring to the greater San Diego community. Twelve high dynamic range broadband and strong motion sensors adjacent to the San Jacinto Fault zone contribute data for earthquake source studies and continue the monitoring of the seismic activity of the San Jacinto fault initiated 24 years ago. Five additional stations are located in the San Diego region with one more station on San Clemente Island. The ANZA network uses the advance wireless networking capabilities of the NSF High Performance Wireless Research and Education Network (http:hpwren.ucsd.edu) to provide the communication infrastructure for the real-time telemetry of Anza seismic stations. The ANZA network uses the Antelope data acquisition software. The combination of high quality hardware, communications, and software allow for an annual network uptime in excess of 99.5% with a median annual station real-time data return rate of 99.3%. Approximately 90,000 events, dominantly local sources but including regional and teleseismic events, comprise the ANZA network waveform database. All waveform data and event data are managed using the Datascope relational database. The ANZA network data has been used in a variety of scientific research including detailed structure of the San Jacinto Fault Zone, earthquake source physics, spatial and temporal studies of aftershocks, array studies of teleseismic body waves, and array studies on the source of microseisms. To augment the location, detection, and high frequency observations of the seismic source spectrum from local
Seismic local site effects characterization in the Andarax River Valley (SE Spain) from ambient seismic noise
Carmona, Enrique; GarcÃa-Jerez, Antonio; Luzón, Francisco; Sánchez-Martos, Francisco; Sánchez-Sesma, Francisco J.; Piña, José
This work is focused on the characterization of seismic local effects in the Low Andarax River Valley (SE Spain). The Low Andarax River valley is located in an active seismic region, with the higher seismic hazard values in Spain. The landform is composed mainly by sedimentary materials which increase its seismic hazard due to the amplification of the seismic inputs and spectral resonances. We study seismic local effects in the Low Andarax River by analyzing the Horizontal-to-Vertical Spectral Ratio (HVSR) of ambient noise records. The noise data were recorded during two field campaigns in 2012 and 2013. There have been a total of 374 noise measurements with 15 and 30 minutes duration. The acquisition was performed with a Digital Broadband Seismometer Guralp CMG-6TD. The distance between measurements was about 200 meters, covering an area around 40 km2. There have been 6 significant peak frequencies between 0.3 Hz and 5 Hz. It was possible to find interesting areas with similar spectral peaks that coincide with zones with similar microgravimetric anomalies at the alluvial valley. It is also observed a decrease in the frequency peaks from West to East suggesting increased sediment layer. We also compute the soil models at those sites where geotechnical information is available, assuming that the seismic noise is diffuse. We invert the HVSR for these places using horizontally layered models and in the imaginary part the Green functions at the source. It is observed that the S wave velocity inverted models are consistent with the known geotechnical information obtained from drilled boreholes. We identify the elastodynamic properties of the limestone-dolomite materials with a formation of phyllites and quartzite that form the basement of the depression, and those properties of the Miocene and Pliocene detrital deposits (marls, sandy silts, sands and conglomerates) that fill the valley. These results together with the observed resonant frequencies along the Andarax
The California Integrated Seismic Network
Hellweg, M.; Given, D.; Hauksson, E.; Neuhauser, D.; Oppenheimer, D.; Shakal, A.
The mission of the California Integrated Seismic Network (CISN) is to operate a reliable, modern system to monitor earthquakes throughout the state; to generate and distribute information in real-time for emergency response, for the benefit of public safety, and for loss mitigation; and to collect and archive data for seismological and earthquake engineering research. To meet these needs, the CISN operates data processing and archiving centers, as well as more than 3000 seismic stations. Furthermore, the CISN is actively developing and enhancing its infrastructure, including its automated processing and archival systems. The CISN integrates seismic and strong motion networks operated by the University of California Berkeley (UCB), the California Institute of Technology (Caltech), and the United States Geological Survey (USGS) offices in Menlo Park and Pasadena, as well as the USGS National Strong Motion Program (NSMP), and the California Geological Survey (CGS). The CISN operates two earthquake management centers (the NCEMC and SCEMC) where statewide, real-time earthquake monitoring takes place, and an engineering data center (EDC) for processing strong motion data and making it available in near real-time to the engineering community. These centers employ redundant hardware to minimize disruptions to the earthquake detection and processing systems. At the same time, dual feeds of data from a subset of broadband and strong motion stations are telemetered in real- time directly to both the NCEMC and the SCEMC to ensure the availability of statewide data in the event of a catastrophic failure at one of these two centers. The CISN uses a backbone T1 ring (with automatic backup over the internet) to interconnect the centers and the California Office of Emergency Services. The T1 ring enables real-time exchange of selected waveforms, derived ground motion data, phase arrivals, earthquake parameters, and ShakeMaps. With the goal of operating similar and redundant
Seismic detection of tornadoes
Tatom, F. B.
Tornadoes represent the most violent of all forms of atmospheric storms, each year resulting in hundreds of millions of dollars in property damage and approximately one hundred fatalities. In recent years, considerable success has been achieved in detecting tornadic storms by means of Doppler radar. However, radar systems cannot determine when a tornado is actually in contact with the ground, expect possibly at extremely close range. At the present time, human observation is the only truly reliable way of knowing that a tornado is actually on the ground. However, considerable evidence exists indicating that a tornado in contact with the ground produces a significant seismic signal. If such signals are generated, the seismic detection and warning of an imminent tornado can become a distinct possibility.Â
Digital Elevation Models
The Earth Science Information Center (ESIC) distributes digital cartographic/geographic data files produced by the U.S. Geological Survey (USGS) as part of the National Mapping Program. Digital cartographic data files may be grouped into four basic types. The first of these, called a Digital Line Graph (DLG), is the line map information in digital form. These data files include information on base data categories, such as transportation, hypsography, hydrography, and boundaries. The second type, called a Digital Elevation Model (DEM), consists of a sampled array of elevations for a number of ground positions at regularly spaced intervals. The third type is Land Use and Land Cover digital data which provides information on nine major classes of land use such as urban, agricultural, or forest as well as associated map data such as political units and Federal land ownership. The fourth type, the Geographic Names Information System, provides primary information for all known places, features, and areas in the United States identified by a proper name.
Mobile seismic exploration
Dräbenstedt, A., E-mail: a.draebenstedt@polytec.de, E-mail: rembe@iei.tu-clausthal.de, E-mail: ulrich.polom@liag-hannover.de; Seyfried, V.; Cao, X.
Laser-Doppler-Vibrometry (LDV) is an established technique to measure vibrations in technical systems with picometer vibration-amplitude resolution. Especially good sensitivity and resolution can be achieved at an infrared wavelength of 1550 nm. High-resolution vibration measurements are possible over more than 100 m distance. This advancement of the LDV technique enables new applications. The detection of seismic waves is an application which has not been investigated so far because seismic waves outside laboratory scales are usually analyzed at low frequencies between approximately 1 Hz and 250 Hz and require velocity resolutions in the range below 1 nm/s/√Hz. Thermal displacements and air turbulence have critical influences to LDVmore » measurements at this low-frequency range leading to noise levels of several 100 nm/√Hz. Commonly seismic waves are measured with highly sensitive inertial sensors (geophones or Micro Electro-Mechanical Sensors (MEMS)). Approaching a laser geophone based on LDV technique is the topic of this paper. We have assembled an actively vibration-isolated optical table in a minivan which provides a hole in its underbody. The laser-beam of an infrared LDV assembled on the optical table impinges the ground below the car through the hole. A reference geophone has detected remaining vibrations on the table. We present the results from the first successful experimental demonstration of contactless detection of seismic waves from a movable vehicle with a LDV as laser geophone.« less

Birth of the Program for Array Seismic Studies of the Continental Lithosphere (PASSCAL)
James, D. E.; Sacks, I. S.
As recently as 1984 institutions doing portable seismology depended upon their own complement of instruments, almost all designed and built in-house, and all of limited recording capability and flexibility. No data standards existed. Around 1980 the National Research Council (NRC) of the National Academy of Sciences (NAS), with National Science Foundation (NSF) support, empanelled a committee to study a major new initiative in Seismic Studies of the Continental Lithosphere (SSCL). The SSCL report in 1983 recommended that substantial numbers (1000 or more) of new generation digital seismographs be acquired for 3-D high resolution imaging of the continental lithosphere. Recommendations of the SSCL committee dovetailed with other NRC/NAS and NSF reports that highlighted imaging of the continental lithosphere as an area of highest priority. For the first time in the history of portable seismology the question asked was "What do seismologists need to do the job right?" A grassroots effort was undertaken to define instrumentation and data standards for a powerful new set of modern seismic research tools to serve the national seismological community. In the spring and fall of 1983 NSF and IASPEI sponsored workshops were convened to develop specifications for the design of a new generation of portable instrumentation. PASSCAL was the outgrowth of these seminal studies and workshops. The first step toward the formal formation of PASSCAL began with an ad-hoc organizing committee, comprised largely of the members of the NAS lithospheric seismology panel, convened by the authors at Carnegie Institution in Washington in November 1983. From that meeting emerged plans and promises of NSF support for an open organizational meeting to be held in January 1984, in Madison, Wisconsin. By the end of the two-day Madison meeting PASSCAL and an official consortium of seismological institutions for portable seismology were realities. Shortly after, PASSCAL merged with the complementary
Seismic hazard in the Intermountain West
Haller, Kathleen; Moschetti, Morgan P.; Mueller, Charles; Rezaeian, Sanaz; Petersen, Mark D.; Zeng, Yuehua
The 2014 national seismic-hazard model for the conterminous United States incorporates new scientific results and important model adjustments. The current model includes updates to the historical catalog, which is spatially smoothed using both fixed-length and adaptive-length smoothing kernels. Fault-source characterization improved by adding faults, revising rates of activity, and incorporating new results from combined inversions of geologic and geodetic data. The update also includes a new suite of published ground motion models. Changes in probabilistic ground motion are generally less than 10% in most of the Intermountain West compared to the prior assessment, and ground-motion hazard in four Intermountain West cities illustrates the range and magnitude of change in the region. Seismic hazard at reference sites in Boise and Reno increased as much as 10%, whereas hazard in Salt Lake City decreased 5–6%. The largest change was in Las Vegas, where hazard increased 32–35%.
Seismicity in South Carolina
Shedlock, K.M.
The largest historical earthquake in South Carolina, and in the southeastern US, occurred in the Coastal Plain province, probably northwest of Charleston, in 1886. Locations for aftershocks associated with this earthquake, estimated using intensities based on newspaper accounts, defined a northwest trending zone about 250 km long that was at least 100 km wide in the Coastal Plain but widened to a northeast trending zone in the Piedmont. The subsequent historical and instrumentally recorded seismicity in South Carolina images the 1886 aftershock zone. Instrumentally recorded seismicity in the Coastal Plain province occurs in 3 seismic zones or clusters: Middleton Place-Summervile (MPSSZ), Adams Run (ARC), and Bowman (BSZ). Approximately 68% of the Coastal Plain earthquakes occur in the MPSSZ, a north trending zone about 22 km long and 12 km wide, lying about 20 km northwest of Charleston. The hypocenters of MPSSZ earthquakes range in depth from near the surface to almost 12 km. Thrust, strike-slip, and some normal faulting are indicated by the fault plane solutions for Coastal Plain earthquakes. The maximum horizontal compressive stress, inferred from the P-axes of the fault plane solutions, is oriented NE-SW in the shallow crust (<9 km deep) but appears to be diffusely E-W between 9 to 12 km deep. -from Author

Digital data from the Great Sand Dunes airborne gravity gradient survey, south-central Colorado
Drenth, B.J.; Abraham, J.D.; Grauch, V.J.S.; Labson, V.F.; Hodges, G.
This report contains digital data and supporting explanatory files describing data types, data formats, and survey procedures for a high-resolution airborne gravity gradient (AGG) survey at Great Sand Dunes National Park, Alamosa and Saguache Counties, south-central Colorado. In the San Luis Valley, the Great Sand Dunes survey covers a large part of Great Sand Dunes National Park and Preserve. The data described were collected from a high-resolution AGG survey flown in February 2012, by Fugro Airborne Surveys Corp., on contract to the U.S. Geological Survey. Scientific objectives of the AGG survey are to investigate the subsurface structural framework that may influence groundwater hydrology and seismic hazards, and to investigate AGG methods and resolution using different flight specifications. Funding was provided by an airborne geophysics training program of the U.S. Department of Defense's Task Force for Business & Stability Operations.
The SISIFO project: Seismic Safety at High Schools
Peruzza, Laura; Barnaba, Carla; Bragato, Pier Luigi; Dusi, Alberto; Grimaz, Stefano; Malisan, Petra; Saraò, Angela; Mucciarelli, Marco
For many years, the Italian scientific community has faced the problem of the reduction of earthquake risk using innovative educational techniques. Recent earthquakes in Italy and around the world have clearly demonstrated that seismic codes alone are not able to guarantee an effective mitigation of risk. After the tragic events of San Giuliano di Puglia (2002), where an earthquake killed 26 school children, special attention was paid in Italy to the seismic safety of schools, but mainly with respect to structural aspects. Little attention has been devoted to the possible and even significant damage to non-structural elements (collapse of ceilings, tipping of cabinets and shelving, obstruction of escape routes, etc..). Students and teachers trained on these aspects may lead to a very effective preventive vigilance. Since 2002, the project EDURISK (www.edurisk.it) proposed educational tools and training programs for schools, at primary and middle levels. More recently, a nationwide campaign aimed to adults (www.iononrischio.it) was launched with the extensive support of civil protection volounteers. There was a gap for high schools, and Project SISIFO was designed to fill this void and in particular for those schools with technical/scientific curricula. SISIFO (https://sites.google.com/site/ogssisifo/) is a multidisciplinary initiative, aimed at the diffusion of scientific culture for achieving seismic safety in schools, replicable and can be structured in training the next several years. The students, helped by their teachers and by experts from scientific institutions, followed a course on specialized training on earthquake safety. The trial began in North-East Italy, with a combination of hands-on activities for the measurement of earthquakes with low-cost instruments and lectures with experts in various disciplines, accompanied by specifically designed teaching materials, both on paper and digital format. We intend to raise teachers and students knowledge of the
Seismic Imager Space Telescope
Sidick, Erkin; Coste, Keith; Cunningham, J.; Sievers,Michael W.; Agnes, Gregory S.; Polanco, Otto R.; Green, Joseph J.; Cameron, Bruce A.; Redding, David C.; Avouac, Jean Philippe;
A concept has been developed for a geostationary seismic imager (GSI), a space telescope in geostationary orbit above the Pacific coast of the Americas that would provide movies of many large earthquakes occurring in the area from Southern Chile to Southern Alaska. The GSI movies would cover a field of view as long as 300 km, at a spatial resolution of 3 to 15 m and a temporal resolution of 1 to 2 Hz, which is sufficient for accurate measurement of surface displacements and photometric changes induced by seismic waves. Computer processing of the movie images would exploit these dynamic changes to accurately measure the rapidly evolving surface waves and surface ruptures as they happen. These measurements would provide key information to advance the understanding of the mechanisms governing earthquake ruptures, and the propagation and arrest of damaging seismic waves. GSI operational strategy is to react to earthquakes detected by ground seismometers, slewing the satellite to point at the epicenters of earthquakes above a certain magnitude. Some of these earthquakes will be foreshocks of larger earthquakes; these will be observed, as the spacecraft would have been pointed in the right direction. This strategy was tested against the historical record for the Pacific coast of the Americas, from 1973 until the present. Based on the seismicity recorded during this time period, a GSI mission with a lifetime of 10 years could have been in position to observe at least 13 (22 on average) earthquakes of magnitude larger than 6, and at least one (2 on average) earthquake of magnitude larger than 7. A GSI would provide data unprecedented in its extent and temporal and spatial resolution. It would provide this data for some of the world's most seismically active regions, and do so better and at a lower cost than could be done with ground-based instrumentation. A GSI would revolutionize the understanding of earthquake dynamics, perhaps leading ultimately to effective warning
NSR&D Program Fiscal Year (FY) 2015 Call for Proposals Mitigation of Seismic Risk at Nuclear Facilities using Seismic Isolation
Coleman, Justin
Seismic isolation (SI) has the potential to drastically reduce seismic response of structures, systems, or components (SSCs) and therefore the risk associated with large seismic events (large seismic event could be defined as the design basis earthquake (DBE) and/or the beyond design basis earthquake (BDBE) depending on the site location). This would correspond to a potential increase in nuclear safety by minimizing the structural response and thus minimizing the risk of material release during large seismic events that have uncertainty associated with their magnitude and frequency. The national consensus standard America Society of Civil Engineers (ASCE) Standard 4, Seismic Analysismore » of Safety Related Nuclear Structures recently incorporated language and commentary for seismically isolating a large light water reactor or similar large nuclear structure. Some potential benefits of SI are: 1) substantially decoupling the SSC from the earthquake hazard thus decreasing risk of material release during large earthquakes, 2) cost savings for the facility and/or equipment, and 3) applicability to both nuclear (current and next generation) and high hazard non-nuclear facilities. Issue: To date no one has evaluated how the benefit of seismic risk reduction reduces cost to construct a nuclear facility. Objective: Use seismic probabilistic risk assessment (SPRA) to evaluate the reduction in seismic risk and estimate potential cost savings of seismic isolation of a generic nuclear facility. This project would leverage ongoing Idaho National Laboratory (INL) activities that are developing advanced (SPRA) methods using Nonlinear Soil-Structure Interaction (NLSSI) analysis. Technical Approach: The proposed study is intended to obtain an estimate on the reduction in seismic risk and construction cost that might be achieved by seismically isolating a nuclear facility. The nuclear facility is a representative pressurized water reactor building nuclear power plant (NPP
Seismic hazard estimation of northern Iran using smoothed seismicity
Khoshnevis, Naeem; Taborda, Ricardo; Azizzadeh-Roodpish, Shima; Cramer, Chris H.
This article presents a seismic hazard assessment for northern Iran, where a smoothed seismicity approach has been used in combination with an updated seismic catalog and a ground motion prediction equation recently found to yield good fit with data. We evaluate the hazard over a geographical area including the seismic zones of Azerbaijan, the Alborz Mountain Range, and Kopeh-Dagh, as well as parts of other neighboring seismic zones that fall within our region of interest. In the chosen approach, seismic events are not assigned to specific faults but assumed to be potential seismogenic sources distributed within regular grid cells. After performing the corresponding magnitude conversions, we decluster both historical and instrumental seismicity catalogs to obtain earthquake rates based on the number of events within each cell, and smooth the results to account for the uncertainty in the spatial distribution of future earthquakes. Seismicity parameters are computed for each seismic zone separately, and for the entire region of interest as a single uniform seismotectonic region. In the analysis, we consider uncertainties in the ground motion prediction equation, the seismicity parameters, and combine the resulting models using a logic tree. The results are presented in terms of expected peak ground acceleration (PGA) maps and hazard curves at selected locations, considering exceedance probabilities of 2 and 10% in 50 years for rock site conditions. According to our results, the highest levels of hazard are observed west of the North Tabriz and east of the North Alborz faults, where expected PGA values are between about 0.5 and 1 g for 10 and 2% probability of exceedance in 50 years, respectively. We analyze our results in light of similar estimates available in the literature and offer our perspective on the differences observed. We find our results to be helpful in understanding seismic hazard for northern Iran, but recognize that additional efforts are necessary to

Comment on "How can seismic hazard around the New Madrid seismic zone be similar to that in California?" by Arthur Frankel
Wang, Z.; Shi, B.; Kiefer, J.D.
PSHA is the method used most to assess seismic hazards for input into various aspects of public and financial policy. For example, PSHA was used by the U.S. Geological Survey to develop the National Seismic Hazard Maps (Frankel et al., 1996, 2002). These maps are the basis for many national, state, and local seismic safety regulations and design standards, such as the NEHRP Recommended Provisions for Seismic Regulations for New Buildings and Other Structures, the International Building Code, and the International Residential Code. Adoption and implementation of these regulations and design standards would have significant impacts on many communities in the New Madrid area, including Memphis, Tennessee and Paducah, Kentucky. Although "mitigating risks to society from earthquakes involves economic and policy issues" (Stein, 2004), seismic hazard assessment is the basis. Seismologists should provide the best information on seismic hazards and communicate them to users and policy makers. There is a lack of effort in communicating the uncertainties in seismic hazard assessment in the central U.S., however. Use of 10%, 5%, and 2% PE in 50 years causes confusion in communicating seismic hazard assessment. It would be easy to discuss and understand the design ground motions if the true meaning of the ground motion derived from PSHA were presented, i.e., the ground motion with the estimated uncertainty or the associated confidence level.
Multichannel seismic-reflection profiles collected in 1979 aboard M/V Seismic Explorer on the western Florida shelf
Ball, M.M.; Soderberg, N.K.
In August 1979, the U.S. Geological Survey (USGS) aboard the M/V SEISMIC EXPLORER of Seismic Explorations International (SEI), ran 17 lines (1,270 km) of multichannel, seismic-reflection profiles on the western Florida Shelf. The main features of the SEI system were (1) a digital recorder with an instantaneous-floating-point-gain constant of 24 dB, (2) a 64-channel hydrophone streamer, 3,200 m long, and (3) a 21-airgun array that had a total volume of 2,000 in and a pressure of 2,000 psi. Sampling interval was array to the center of the farthest phone group was 3,338 m and to the nearest phone group, 188 m. Shot points were 5O m apart to obtain a 32-fold stack. Navigation was by an integrated satellite/Loran/doppler-sonar system.The SEI data were processed by Geophysical Data Processing Center, Inc. of Houston, Texas. Processing procedures were standard with the following exceptions: (1) a deringing deconvolution that had a 128-ms operator length was done prior to stacking. (2) a time-variant predictive deconvolution that had a filter operator length of 100 ms and automatic picking of the second zero-crossing was applied after stacking to further suppress multiple energy. (3) Velocity analyses were performed every 3 km, using a technique that included the determination and consideration of both the amount and direction of apparent dip. (4) Automatic gain ranging using a 750-ms window was applied pre- and post-stack. ( 5) Lines affected by sea floor's angle of slope were deconvolved again before stacking and time-variant filter parameters were adjusted to follow the sea-floor geometry.The data taken with the 3,200-m streamer and 2,000 in3 airgun array, aboard M/V SEISMIC EXPLORER (Arabic numerals) are vastly superior to those obtained by R/V GYRE using a much smaller streamer and source (Roman numerals). The former consistently show coherent primary events from within the units underlying the Mesozoic section on the western Florida Shelf, while the latter tend to do
Validating induced seismicity forecast models—Induced Seismicity Test Bench
Király-Proag, Eszter; Zechar, J. Douglas; Gischig, Valentin; Wiemer, Stefan; Karvounis, Dimitrios; Doetsch, Joseph
Induced earthquakes often accompany fluid injection, and the seismic hazard they pose threatens various underground engineering projects. Models to monitor and control induced seismic hazard with traffic light systems should be probabilistic, forward-looking, and updated as new data arrive. In this study, we propose an Induced Seismicity Test Bench to test and rank such models; this test bench can be used for model development, model selection, and ensemble model building. We apply the test bench to data from the Basel 2006 and Soultz-sous-Forêts 2004 geothermal stimulation projects, and we assess forecasts from two models: Shapiro and Smoothed Seismicity (SaSS) and Hydraulics and Seismics (HySei). These models incorporate a different mix of physics-based elements and stochastic representation of the induced sequences. Our results show that neither model is fully superior to the other. Generally, HySei forecasts the seismicity rate better after shut-in but is only mediocre at forecasting the spatial distribution. On the other hand, SaSS forecasts the spatial distribution better and gives better seismicity rate estimates before shut-in. The shut-in phase is a difficult moment for both models in both reservoirs: the models tend to underpredict the seismicity rate around, and shortly after, shut-in.
The Virtual Seismic Atlas Project: sharing the interpretation of seismic data
Butler, R.; Mortimer, E.; McCaffrey, B.; Stuart, G.; Sizer, M.; Clayton, S.
Through the activities of academic research programs, national institutions and corporations, especially oil and gas companies, there is a substantial volume of seismic reflection data. Although the majority is proprietary and confidential, there are significant volumes of data that are potentially within the public domain and available for research. Yet the community is poorly connected to these data and consequently geological and other research using seismic reflection data is limited to very few groups of researchers. This is about to change. The Virtual Seismic Atlas (VSA) is generating an independent, free-to-use, community based internet resource that captures and shares the geological interpretation of seismic data globally. Images and associated documents are explicitly indexed using not only existing survey and geographical data but also on the geology they portray. By using "Guided Navigation" to search, discover and retrieve images, users are exposed to arrays of geological analogues that provide novel insights and opportunities for research and education. The VSA goes live, with evolving content and functionality, through 2008. There are opportunities for designed integration with other global data programs in the earth sciences.
Accelerating Harmonization in Digital Health.
Moore, Carolyn; Werner, Laurie; BenDor, Amanda Puckett; Bailey, Mike; Khan, Nighat
Digital tools play an important role in supporting front-line health workers who deliver primary care. This paper explores the current state of efforts undertaken to move away from single-purpose applications of digital health towards integrated systems and solutions that align with national strategies. Through examples from health information systems, data and health worker training, this paper demonstrates how governments and stakeholders are working to integrate digital health services. We emphasize three factors as crucial for this integration: development and implementation of national digital health strategies; technical interoperability and collaborative approaches to ensure that digital health has an impact on the primary care level. Consolidation of technologies will enable an integrated, scaleable approach to the use of digital health to support health workers. As this edition explores a paradigm shift towards harmonization in primary healthcare systems, this paper explores complementary efforts undertaken to move away from single-purpose applications of digital health towards integrated systems and solutions that align with national strategies. It describes a paradigm shift towards integrated and interoperable systems that respond to health workers' needs in training, data and health information; and calls for the consolidation and integration of digital health tools and approaches across health areas, functions and levels of the health system. It then considers the critical factors that must be in place to support this paradigm shift. This paper aims not only to describe steps taken to move from fractured pilots to effective systems, but to propose a new perspective focused on consolidation and collaboration guided by national digital health strategies.
Seismic vibration source
Dowler, W. L.; Varsi, G.; Yang, L. C. (Inventor)
A system for vibrating the earth in a location where seismic mapping is to take place is described. A relatively shallow hole formed in the earth, such as a hole 10 feet deep, placing a solid propellant in the hole, sealing a portion of the hole above the solid propellant with a device that can rapidly open and close to allow a repeatedly interrupted escape of gas. The propellant is ignited so that high pressure gas is created which escapes in pulses to vibrate the earth.
Seismic risk assessment for road in Indonesia
Toyfur, Mona Foralisa; Pribadi, Krishna S.
Road networks in Indonesia consist of 446,000 km of national, provincial and local roads as well as toll highways. Indonesia is one of countries that exposed to various natural hazards, such as earthquakes, floods, landslides, etc. Within the Indonesian archipelago, several global tectonic plates interact, such as the Indo-Australian, Pacific, Eurasian, resulting in a complex geological setting, characterized by the existence of seismically active faults and subduction zones and a chain of more than one hundred active volcanoes. Roads in Indonesia are vital infrastructure needed for people and goods movement, thus supporting community life and economic activities, including promoting regional economic development. Road damages and losses due to earthquakes have not been studied widely, whereas road disruption caused enormous economic damage. The aim of this research is to develop a method to analyse risk caused by seismic hazard to roads. The seismic risk level of road segment is defined using an earthquake risk index, adopting the method of Earthquake Disaster Risk Index model developed by Davidson (1997). Using this method, road segments' risk level can be defined and compared, and road risk map can be developed as a tool for prioritizing risk mitigation programs for road networks in Indonesia.
Next Generation Polar Seismic Instrumentation Challenges
Parker, T.; Beaudoin, B. C.; Gridley, J.; Anderson, K. R.
Polar region logistics are the limiting factor for deploying deep field seismic arrays. The IRIS PASSCAL Instrument Center, in collaboration with UNAVCO, designed and deployed several systems that address some of the logistical constraints of polar deployments. However, continued logistics' pressures coupled with increasingly ambitious science projects require further reducing the logistics required for deploying both summer and over winter stations. Our focus is to reduce station power requirements and bulk, thereby minimizing the time and effort required to deploy these arrays. We will reduce the weight of the battery bank by incorporating the most applicable new high energy-density battery technology. Using these batteries will require a completely new power management system along with an appropriate smart enclosure. The other aspect will be to integrate the digitizing system with the sensor. Both of these technologies should reduce the install time and shipping volume plus weight while reducing some instrument costs. We will also continue work on an effective Iridium telemetry solution for automated data return. The costs and limitations of polar deep-field science easily justifies a specialized development effort but pays off doubly in that we will continue to leverage the advancements in reduced logistics and increased performance for the benefit of low-latitude seismic research.
Software of Seismic Proportions Promotes Enjoyable Learning
While working for NASA, Jack Sculley and Terry Brooks had a revelation. They wanted to find a novel and unique way to present the scientific principles of NASA research to the public, so as to not only enlighten, but entertain. Suddenly, their revelation morphed into something even grander. "Why stop at NASA?" they asked themselves. With this thought, Sculley and Brooks left NASA and set out to convey voluminous scientific findings from different organizations in the form of digital, interactive media that would enhance the exploration and adventure interests of people of all ages. Sculley, a former researcher at Ames Research Center, the Jet Propulsion Laboratory (JPL), and Apple, Inc. s and LucasFilm Ltd. s multimedia labs, and Brooks, a former public information officer at JPL and an Emmy award-winning documentary film producer, founded Seismic Entertainment in 1989 to communicate their "edutainment" ideas. The two acknowledge that NASA has provided much of the inspiration and content for Seismic Entertainment over the past decade and a half. Additionally, Sculley s experience as a virtual reality and Mars specialist and Brooks s experience creating NASA public access programs were significant to the San Francisco-based company s success. Its most recent project, "Inside NASA," provides virtual tours of NASA s field centers and allows for a comprehensive focus on the broad range of NASA programs for the benefit of the general public
Historical seismometry database project: A comprehensive relational database for historical seismic records
Bono, Andrea
The recovery and preservation of the patrimony made of the instrumental registrations regarding the historical earthquakes is with no doubt a subject of great interest. This attention, besides being purely historical, must necessarily be also scientific. In fact, the availability of a great amount of parametric information on the seismic activity in a given area is a doubtless help to the seismologic researcher's activities. In this article the project of the Sismos group of the National Institute of Geophysics and Volcanology of Rome new database is presented. In the structure of the new scheme the matured experience of five years of activity is summarized. We consider it useful for those who are approaching to "recovery and reprocess" computer based facilities. In the past years several attempts on Italian seismicity have followed each other. It has almost never been real databases. Some of them have had positive success because they were well considered and organized. In others it was limited in supplying lists of events with their relative hypocentral standards. What makes this project more interesting compared to the previous work is the completeness and the generality of the managed information. For example, it will be possible to view the hypocentral information regarding a given historical earthquake; it will be possible to research the seismograms in raster, digital or digitalized format, the information on times of arrival of the phases in the various stations, the instrumental standards and so on. The relational modern logic on which the archive is based, allows the carrying out of all these operations with little effort. The database described below will completely substitute Sismos' current data bank. Some of the organizational principles of this work are similar to those that inspire the database for the real-time monitoring of the seismicity in use in the principal offices of international research.

The Crustal Structure and Seismicity of Eastern Venezuela
Schmitz, M.; Martins, A.; Sobiesiak, M.; Alvarado, L.; Vasquez, R.
Eastern Venezuela is characterized by a moderate to high seismicity, evidenced recently by the 1997 Cariaco earthquake located on the El Pilar Fault, a right lateral strike slip fault which marks the plate boundary between the Caribbean and South-American plates in this region. Recently, the seismic activity seems to migrate towards the zone of subduction of the Lesser Antilles in the northeast, where a mb 6.0 earthquake occurred in October 2000 at 120 km of depth. Periodical changes in the seismic activity are related to the interaction of the stress fields of the strike-slip and the subduction regimes. The seismic activity decreases rapidly towards to the south with some disperse events on the northern edge of the Guayana Shield, related to the Guri fault system. The crustal models used in the region are derived from the information generated by the national seismological network since 1982 and by microseismicity studies in northeastern Venezuela, coinciding in a crustal thickness of about 35 km in depth. Results of seismic refraction measurements for the region were obtained during field campains in 1998 (ECOGUAY) for the Guayana Shield and the Cariaco sedimentary basin and in 2001 (ECCO) for the Oriental Basin. The total crustal thickness decreases from about 45 km on the northern edge of the Guayana Shield to some 36 km close to El Tigre in the center of the Oriental Basin. The average crustal velocity decreases in the same sense from 6.5 to 5.8 km/s. In the Cariaco sedimentary basin a young sedimentary cover of 1 km thickness with a seismic velocity of 2 km/s was derived. Towards the northern limit of the South-American plate, no deep seismic refraction data are available up to now. The improvement of the crustal models used in that region would constitute a step forward in the analysis of the seismic hazard. Seismic refraction studies funded by CONICIT S1-97002996 and S1-2000000685 projects and PDVSA (additional drilling and blasting), recording equipment
Seismic and Tectonic Regionalization of the State of Michoacan.
Vazquez Rosas, R.; Aguirre, J.; Garduño-Monroy, V. H.; Ramirez-Guzman, L.
In Mexico it is a country with seismically active regions, mainly the zones that are next to the pacific where the zone of subduction is located, in this work we focus on the state of Michoacán, since this has not been completely studied in the last 30 years after the earthquake in Michoacán in 1985. The first most important step is to know the region which are the most seismic zones within the state and one way is to carry out the regionalization of Michoacán identifying the sources of earthquakes as well as where occur more frequently.If we could know each of the factors that influence seismicity and describe every point of the terrain, every rupture, every rock, etc., then we could describe in an analytical way the seismic process and predict the occurrence of earthquakes such as eclipses. Unfortunately the number of parameters is so enormous that we cannot arrive at an exact description; however, we can take advantage of statistical properties to evaluate probabilities, even in the case of small systems such as a particular seismic zone.In this paper, epicenter data were collected from 1970 to 2014, and with them a statistical study was carried out and the epicenter data plotted using data reported by the National Seismological Service and the IRIS catalog as well as some data from the Institute of engineering UNAM. Where earthquakes of equal and greater than M = 4 were used. Graphing these in function with the depth and with that it was graficaron and was made an overlapping the faults of the state and with that it was divided in 4 seismic zones in function of the faults and the localized seismicity.Zone A. is located within the Michoacán Block set of faults, as well as part of the subduction zone on the coast of the state. Seismicity in this area is high. Zone B-1.

Probabilistic seismic hazard zonation for the Cuban building code update
Garcia, J.; Llanes-Buron, C.
A probabilistic seismic hazard assessment has been performed in response to a revision and update of the Cuban building code (NC-46-99) for earthquake-resistant building construction. The hazard assessment have been done according to the standard probabilistic approach (Cornell, 1968) and importing the procedures adopted by other nations dealing with the problem of revising and updating theirs national building codes. Problems of earthquake catalogue treatment, attenuation of peak and spectral ground acceleration, as well as seismic source definition have been rigorously analyzed and a logic-tree approach was used to represent the inevitable uncertainties encountered through the whole seismic hazard estimation process. The seismic zonation proposed here, is formed by a map where it is reflected the behaviour of the spectral acceleration values for short (0.2 seconds) and large (1.0 seconds) periods on rock conditions with a 1642 -year return period, which being considered as maximum credible earthquake (ASCE 07-05). In addition, other three design levels are proposed (severe earthquake: with a 808 -year return period, ordinary earthquake: with a 475 -year return period and minimum earthquake: with a 225 -year return period). The seismic zonation proposed here fulfils the international standards (IBC-ICC) as well as the world tendencies in this thematic.
Advances in Rotational Seismic Measurements
Pierson, Robert; Laughlin, Darren; Brune, Robert
Rotational motion is increasingly understood to be a significant part of seismic wave motion. Rotations can be important in earthquake strong motion and in Induced Seismicity Monitoring. Rotational seismic data can also enable shear selectivity and improve wavefield sampling for vertical geophones in 3D surveys, among other applications. However, sensor technology has been a limiting factor to date. The US Department of Energy (DOE) and Applied Technology Associates (ATA) are funding a multi-year project that is now entering Phase 2 to develop and deploy a new generation of rotational sensors for validation of rotational seismic applications. Initial focus is onmore » induced seismicity monitoring, particularly for Enhanced Geothermal Systems (EGS) with fracturing. The sensors employ Magnetohydrodynamic (MHD) principles with broadband response, improved noise floors, robustness, and repeatability. This paper presents a summary of Phase 1 results and Phase 2 status.« less
Quantifying the similarity of seismic polarizations
Jones, Joshua P.; Eaton, David W.; Caffagni, Enrico
Assessing the similarities of seismic attributes can help identify tremor, low signal-to-noise (S/N) signals and converted or reflected phases, in addition to diagnosing site noise and sensor misalignment in arrays. Polarization analysis is a widely accepted method for studying the orientation and directional characteristics of seismic phases via computed attributes, but similarity is ordinarily discussed using qualitative comparisons with reference values or known seismic sources. Here we introduce a technique for quantitative polarization similarity that uses weighted histograms computed in short, overlapping time windows, drawing on methods adapted from the image processing and computer vision literature. Our method accounts for ambiguity in azimuth and incidence angle and variations in S/N ratio. Measuring polarization similarity allows easy identification of site noise and sensor misalignment and can help identify coherent noise and emergent or low S/N phase arrivals. Dissimilar azimuths during phase arrivals indicate misaligned horizontal components, dissimilar incidence angles during phase arrivals indicate misaligned vertical components and dissimilar linear polarization may indicate a secondary noise source. Using records of the Mw = 8.3 Sea of Okhotsk earthquake, from Canadian National Seismic Network broad-band sensors in British Columbia and Yukon Territory, Canada, and a vertical borehole array at Hoadley gas field, central Alberta, Canada, we demonstrate that our method is robust to station spacing. Discrete wavelet analysis extends polarization similarity to the time-frequency domain in a straightforward way. Time-frequency polarization similarities of borehole data suggest that a coherent noise source may have persisted above 8 Hz several months after peak resource extraction from a `flowback' type hydraulic fracture.

Seismic event classification system
Dowla, F.U.; Jarpe, S.P.; Maurer, W.
In the computer interpretation of seismic data, the critical first step is to identify the general class of an unknown event. For example, the classification might be: teleseismic, regional, local, vehicular, or noise. Self-organizing neural networks (SONNs) can be used for classifying such events. Both Kohonen and Adaptive Resonance Theory (ART) SONNs are useful for this purpose. Given the detection of a seismic event and the corresponding signal, computation is made of: the time-frequency distribution, its binary representation, and finally a shift-invariant representation, which is the magnitude of the two-dimensional Fourier transform (2-D FFT) of the binary time-frequency distribution. This pre-processed input is fed into the SONNs. These neural networks are able to group events that look similar. The ART SONN has an advantage in classifying the event because the types of cluster groups do not need to be pre-defined. The results from the SONNs together with an expert seismologist's classification are then used to derive event classification probabilities. 21 figures.

Community Seismic Network (CSN)
Clayton, R. W.; Heaton, T. H.; Kohler, M. D.; Chandy, M.; Krause, A.
In collaboration with computer science and earthquake engineering, we are developing a dense network of low-cost accelerometers that send their data via the Internet to a cloud-based center. The goal is to make block-by-block measurements of ground shaking in urban areas, which will provide emergency response information in the case of large earthquakes, and an unprecedented high-frequency seismic array to study structure and the earthquake process with moderate shaking. When deployed in high-rise buildings they can be used to monitor the state of health of the structure. The sensors are capable of a resolution of approximately 80 micro-g, connect via USB ports to desktop computers, and cost about $100 each. The network will adapt to its environment by using network-wide machine learning to adjust the picking sensitivity. We are also looking into using other motion sensing devices such as cell phones. For a pilot project, we plan to deploy more than 1000 sensors in the greater Pasadena area. The system is easily adaptable to other seismically vulnerable urban areas.
Seismic moulin tremor
Roeoesli, Claudia; Walter, Fabian; Ampuero, Jean-Paul; Kissling, Edi
Through glacial moulins, meltwater is routed from the glacier surface to its base. Moulins are a main feature feeding subglacial drainage systems and thus influencing basal motion and ice dynamics, but their geometry remains poorly known. Here we show that analysis of the seismic wavefield generated by water falling into a moulin can help constrain its geometry. We present modeling results of hour-long seimic tremors emitted from a vertical moulin shaft, observed with a seismometer array installed at the surface of the Greenland Ice Sheet. The tremor was triggered when the moulin water level exceeded a certain height, which we associate with the threshold for the waterfall to hit directly the surface of the moulin water column. The amplitude of the tremor signal changed over each tremor episode, in close relation to the amount of inflowing water. The tremor spectrum features multiple prominent peaks, whose characteristic frequencies are distributed like the resonant modes of a semiopen organ pipe and were found to depend on the moulin water level, consistent with a source composed of resonant tube waves (water pressure waves coupled to elastic deformation of the moulin walls) along the water-filled moulin pipe. Analysis of surface particle motions lends further support to this interpretation. The seismic wavefield was modeled as a superposition of sustained wave radiation by pressure sources on the side walls and at the bottom of the moulin. The former was found to dominate the wave field at close distance and the latter at large distance to the moulin.

An Interactive Program on Digitizing Historical Seismograms
Xu, Y.; Xu, T.
Retrieving information from historical seismograms is of great importance since they are considered the unique sources that provide quantitative information of historical earthquakes. Modern techniques of seismology require digital forms of seismograms that are essentially a sequence of time-amplitude pairs. However, the historical seismograms, after scanned into computers, are two dimensional arrays. Each element of the arrays contains the grayscale value or RGB value of the corresponding pixel. The problem of digitizing historical seismograms, referred to as converting historical seismograms to digital seismograms, can be formulated as an inverse problem that generating sequences of time-amplitude pairs from a two dimension arrays. This problem has infinite solutions. The algorithm for automatic digitization of historical seismogram presented considers several features of seismograms, including continuity, smoothness of the seismic traces as the prior information, and assumes that the amplitude is a single-valued function of time. An interactive program based on the algorithm is also presented. The program is developed using Matlab GUI and has both automatic and manual modality digitization. Users can easily switch between them, and try different combinations to get the optimal results. Several examples are given to illustrate the results of digitizing seismograms using the program, including a photographic record and a wide-angle reflection/refraction seismogram. Digitized result of the program (redrawn using Golden Software Surfer for high resolution image). (a) shows the result of automatic digitization, and (b) is the result after manual correction.
Seismic gradiometry using ambient seismic noise in an anisotropic Earth
de Ridder, S. A. L.; Curtis, A.
We introduce a wavefield gradiometry technique to estimate both isotropic and anisotropic local medium characteristics from short recordings of seismic signals by inverting a wave equation. The method exploits the information in the spatial gradients of a seismic wavefield that are calculated using dense deployments of seismic arrays. The application of the method uses the surface wave energy in the ambient seismic field. To estimate isotropic and anisotropic medium properties we invert an elliptically anisotropic wave equation. The spatial derivatives of the recorded wavefield are evaluated by calculating finite differences over nearby recordings, which introduces a systematic anisotropic error. A two-step approach corrects this error: finite difference stencils are first calibrated, then the output of the wave-equation inversion is corrected using the linearized impulse response to the inverted velocity anomaly. We test the procedure on ambient seismic noise recorded in a large and dense ocean bottom cable array installed over Ekofisk field. The estimated azimuthal anisotropy forms a circular geometry around the production-induced subsidence bowl. This conforms with results from studies employing controlled sources, and with interferometry correlating long records of seismic noise. Yet in this example, the results were obtained using only a few minutes of ambient seismic noise.
OGS improvements in 2012 in running the North-eastern Italy Seismic Network: the Ferrara VBB borehole seismic station
Pesaresi, D.; Romanelli, M.; Barnaba, C.; Bragato, P. L.; Durì, G.
The Centro di Ricerche Sismologiche (CRS, Seismological Research Centre) of the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS, Italian National Institute for Oceanography and Experimental Geophysics) in Udine (Italy) after the strong earthquake of magnitude M=6.4 occurred in 1976 in the Italian Friuli-Venezia Giulia region, started to operate the North-eastern Italy Seismic Network: it currently consists of 17 very sensitive broad band and 18 simpler short period seismic stations, all telemetered to and acquired in real time at the OGS-CRS data centre in Udine. Real time data exchange agreements in place with other Italian, Slovenian, Austrian and Swiss seismological institutes lead to a total number of about 100 seismic stations acquired in real time, which makes the OGS the reference institute for seismic monitoring of North-eastern Italy. The south-western edge of the OGS seismic network (Fig. 1) stands on the Po alluvial basin: earthquake localization and characterization in this area is affected by the presence of soft alluvial deposits. OGS ha already experience in running a local seismic network in high noise conditions making use of borehole installations in the case of the micro-seismicity monitoring of a local gas storage site for a private company. Following the ML = 5.9 earthquake that struck the Emilia region around Ferrara in Northern Italy on 20 May 2012 at 02:03:53 UTC, a cooperation of Istituto Nazionale di Geofisica e Vulcanologia, OGS, the Comune di Ferrara and the University of Ferrara lead to the reinstallation of a previously existing very broad band (VBB) borehole seismic station in Ferrara. The aim of the OGS intervention was on one hand to extend its real time seismic monitoring capabilities toward South-West, including Ferrara and its surroundings, and on the other hand to evaluate the seismic response at the site. We will describe improvements in running the North-eastern Italy Seismic Network, including details of
Continuous, Large-Scale Processing of Seismic Archives for High-Resolution Monitoring of Seismic Activity and Seismogenic Properties
Archives of digital seismic data recorded by seismometer networks around the world have grown tremendously over the last several decades helped by the deployment of seismic stations and their continued operation within the framework of monitoring earthquake activity and verification of the Nuclear Test-Ban Treaty. We show results from our continuing effort in developing efficient waveform cross-correlation and double-difference analysis methods for the large-scale processing of regional and global seismic archives to improve existing earthquake parameter estimates, detect seismic events with magnitudes below current detection thresholds, and improve real-time monitoring procedures. We demonstrate the performance of these algorithms as applied to the 28-year long seismic archive of the Northern California Seismic Network. The tools enable the computation of periodic updates of a high-resolution earthquake catalog of currently over 500,000 earthquakes using simultaneous double-difference inversions, achieving up to three orders of magnitude resolution improvement over existing hypocenter locations. This catalog, together with associated metadata, form the underlying relational database for a real-time double-difference scheme, DDRT, which rapidly computes high-precision correlation times and hypocenter locations of new events with respect to the background archive (http://ddrt.ldeo.columbia.edu). The DDRT system facilitates near-real-time seismicity analysis, including the ability to search at an unprecedented resolution for spatio-temporal changes in seismogenic properties. In areas with continuously recording stations, we show that a detector built around a scaled cross-correlation function can lower the detection threshold by one magnitude unit compared to the STA/LTA based detector employed at the network. This leads to increased event density, which in turn pushes the resolution capability of our location algorithms. On a global scale, we are currently building

measured and derived VLF parameters are compared with VLF observations several weeks before an earthquake (e.g. L'Aquila, Italy, April 6, 2009) and with co- and post-seismic phenomena.

Induced Seismicity: Balancing the Scientific Process With the Need for Rapid Communication of Evolving Seismic Hazards
Cochran, E. S.; Ellsworth, W. L.; Llenos, A. L.; Rubinstein, J. L.
studies changed the public discourse from providing primary information about the on-going earthquake sequences to how to mitigate the hazard associated with wastewater injection. And, scientific studies are now focused on how to include the impact of induced events within the National Seismic Hazard Maps (e.g. Peterson et al., 2014).
Application of a time probabilistic approach to seismic landslide hazard estimates in Iran
Rajabi, A. M.; Del Gaudio, V.; Capolongo, D.; Khamehchiyan, M.; Mahdavifar, M. R.
the slope critical acceleration (Ac)x for which a prefixed probability exists that seismic shaking would result in a Dn value equal to a threshold x whose exceedence would cause landslide triggering. The obtained ac values represent the minimum slope resistance required to keep the probability of seismic-landslide triggering within the prefixed value. In particular we calculated the spatial distribution of (Ac)x for x thresholds of 10 and 2 cm in order to represent triggering conditions for coherent slides (e.g., slumps, block slides, slow earth flows) and disrupted slides (e.g., rock falls, rock slides, rock avalanches), respectively. Then we produced a probabilistic national map that shows the spatial distribution of (Ac)10 and (Ac)2, for a 10% probability of exceedence in 50 year, which is a significant level of hazard equal to that commonly used for building codes. The spatial distribution of the calculated (Ac)xvalues can be compared with the in situ actual ac values of specific slopes to estimate whether these slopes have a significant probability of failing under seismic action in the future. As example of possible application of this kind of time probabilistic map to hazard estimates, we compared the values obtained for the Manjil region with a GIS map providing spatial distribution of estimated ac values in the same region. The spatial distribution of slopes characterized by ac < (Ac)10 was then compared with the spatial distribution of the major landslides of coherent type triggered by the Manjil earthquake. This comparison provides indications on potential, problems and limits of the experimented approach for the study area. References Cornell, C.A., 1968: Engineering seismic risk analysis, Bull. Seism.

New Observations of Seismic Group Velocities in the Western Solomon Islands from Cross-Correlation of Ambient Seismic Noise
Ku, C. S.; You, S. H.; Kuo, Y. T.; Huang, B. S.; Wu, Y. M.; Chen, Y. G.; Taylor, F. W.
A MW 8.1 earthquake occurred on 1 April 2007 in the western Solomon Islands. Following this event, a damaging tsunami was induced and hit the Island Gizo where the capital city of Western Province of Solomon Islands located. Several buildings of this city were destroyed and several peoples lost their lives during this earthquake. However, during this earthquake, no near source seismic instrument has been installed in this region. The seismic evaluations for the aftershock sequence, the possible earthquake early warning and tsunami warning were unavailable. For the purpose of knowing more detailed information about seismic activity in this region, we have installed 9 seismic stations (with Trillium 120PA broadband seismometer and Q330S 24bit digitizer) around the rupture zone of the 2007 earthquake since September of 2009. Within a decade, it has been demonstrated both theoretically and experimentally that the Green's function or impulse response between two seismic stations can be retrieved from the cross-correlation of ambient noise. In this study, 6 stations' observations which are more complete during 2011/10 ~ 2012/12 period, were selected for the purpose of the cross-correlation analysis of ambient seismic noise. The group velocities at period 2-20 seconds of 15 station-pairs were extracted by using multiple filter technique (MFT) method. The analyzed results of this study presented significant results of group velocities with higher frequency contents than other studies (20-60 seconds in usually cases) and opened new opportunities to study the shallow crustal structure of the western Solomon Islands.
GSAC - Generic Seismic Application Computing
Herrmann, R. B.; Ammon, C. J.; Koper, K. D.
With the success of the IRIS data management center, the use of large data sets in seismological research has become common. Such data sets, and especially the significantly larger data sets expected from EarthScope, present challenges for analysis with existing tools developed over the last 30 years. For much of the community, the primary format for data analysis is the Seismic Analysis Code (SAC) format developed by Lawrence Livermore National Laboratory. Although somewhat restrictive in meta-data storage, the simplicity and stability of the format has established it as an important component of seismological research. Tools for working with SAC files fall into two categories - custom research quality processing codes and shared display - processing tools such as SAC2000, MatSeis,etc., which were developed primarily for the needs of individual seismic research groups. While the current graphics display and platform dependence of SAC2000 may be resolved if the source code is released, the code complexity and the lack of large-data set analysis or even introductory tutorials could preclude code improvements and development of expertise in its use. We believe that there is a place for new, especially open source, tools. The GSAC effort is an approach that focuses on ease of use, computational speed, transportability, rapid addition of new features and openness so that new and advanced students, researchers and instructors can quickly browse and process large data sets. We highlight several approaches toward data processing under this model. gsac - part of the Computer Programs in Seismology 3.30 distribution has much of the functionality of SAC2000 and works on UNIX/LINUX/MacOS-X/Windows (CYGWIN). This is completely programmed in C from scratch, is small, fast, and easy to maintain and extend. It is command line based and is easily included within shell processing scripts. PySAC is a set of Python functions that allow easy access to SAC files and enable efficient
Opto-mechanical lab-on-fibre seismic sensors detected the Norcia earthquake.
Pisco, Marco; Bruno, Francesco Antonio; Galluzzo, Danilo; Nardone, Lucia; Gruca, Grzegorz; Rijnveld, Niek; Bianco, Francesca; Cutolo, Antonello; Cusano, Andrea
We have designed and developed lab-on-fibre seismic sensors containing a micro-opto-mechanical cavity on the fibre tip. The mechanical cavity is designed as a double cantilever suspended on the fibre end facet and connected to a proof mass to tune its response. Ground acceleration leads to displacement of the cavity length, which in turn can be remotely detected using an interferometric interrogation technique. After the sensors characterization, an experimental validation was conducted at the Italian National Institute of Geophysics and Volcanology (INGV), which is responsible for seismic surveillance over the Italian country. The fabricated sensors have been continuously used for long periods to demonstrate their effectiveness as seismic accelerometer sensors. During the tests, fibre optic seismic accelerometers clearly detected the seismic sequence that culminated in the severe Mw6.5 Norcia earthquake that struck central Italy on October 30, 2016. The seismic data provided by the optical sensors were analysed by specialists at the INGV. The wave traces were compared with state-of-the-art traditional sensors typically incorporated into the INGV seismic networks. The comparison verifies the high fidelity of the optical sensors in seismic wave detection, indicating their suitability for a novel class of seismic sensors to be employed in practical scenarios.
Seismic Analysis Capability in NASTRAN
Butler, T. G.; Strang, R. F.
Seismic analysis is a technique which pertains to loading described in terms of boundary accelerations. Earthquake shocks to buildings is the type of excitation which usually comes to mind when one hears the word seismic, but this technique also applied to a broad class of acceleration excitations which are applied at the base of a structure such as vibration shaker testing or shocks to machinery foundations. Four different solution paths are available in NASTRAN for seismic analysis. They are: Direct Seismic Frequency Response, Direct Seismic Transient Response, Modal Seismic Frequency Response, and Modal Seismic Transient Response. This capability, at present, is invoked not as separate rigid formats, but as pre-packaged ALTER packets to existing RIGID Formats 8, 9, 11, and 12. These ALTER packets are included with the delivery of the NASTRAN program and are stored on the computer as a library of callable utilities. The user calls one of these utilities and merges it into the Executive Control Section of the data deck to perform any of the four options are invoked by setting parameter values in the bulk data.
Spatial and temporal variation of seismic velocity during earthquakes and volcanic eruptions in western Japan: Insight into mechanism for seismic velocity variation
Tsuji, T.; Ikeda, T.; Nimiya, H.
We report spatio-temporal variations of seismic velocity around the seismogenic faults in western Japan. We mainly focus on the seismic velocity variation during (1) the 2016 Off-Mie earthquake in the Nankai subduction zone (Mw5.8) and (2) the 2016 Kumamoto earthquake in Kyushu Island (Mw7.0). We applied seismic interferometry and surface wave analysis to the ambient noise data recorded by Hi-net and DONET seismometers of National Research Institute for Earth Science and Disaster Resilience (NIED). Seismic velocity near the rupture faults and volcano decreased during the earthquake. For example, we observed velocity reduction around the seismogenic Futagawa-Hinagu fault system and Mt Aso in the 2016 Kumamoto earthquake. We also identified velocity increase after the eruptions of Mt Aso. During the 2016 Off-Mie earthquake, we observed seismic velocity variation in the Nankai accretionary prism. After the earthquakes, the seismic velocity gradually returned to the pre-earthquake value. The velocity recovering process (healing process) is caused by several mechanisms, such as pore pressure reduction, strain change, and crack sealing. By showing the velocity variations obtained at different geologic settings (volcano, seismogenic fault, unconsolidated sediment), we discuss the mechanism of seismic velocity variation as well as the post-seismic fault healing process.
Seismic risk assessment of Navarre (Northern Spain)
Gaspar-Escribano, J. M.; Rivas-Medina, A.; GarcÃa RodrÃguez, M. J.; Benito, B.; Tsige, M.; MartÃnez-DÃaz, J. J.; Murphy, P.
The RISNA project, financed by the Emergency Agency of Navarre (Northern Spain), aims at assessing the seismic risk of the entire region. The final goal of the project is the definition of emergency plans for future earthquakes. With this purpose, four main topics are covered: seismic hazard characterization, geotechnical classification, vulnerability assessment and damage estimation to structures and exposed population. A geographic information system is used to integrate, analyze and represent all information colleted in the different phases of the study. Expected ground motions on rock conditions with a 90% probability of non-exceedance in an exposure time of 50 years are determined following a Probabilistic Seismic Hazard Assessment (PSHA) methodology that includes a logic tree with different ground motion and source zoning models. As the region under study is located in the boundary between Spain and France, an effort is required to collect and homogenise seismological data from different national and regional agencies. A new homogenised seismic catalogue, merging data from Spanish, French, Catalonian and international agencies and establishing correlations between different magnitude scales, is developed. In addition, a new seismic zoning model focused on the study area is proposed. Results show that the highest ground motions on rock conditions are expected in the northeastern part of the region, decreasing southwards. Seismic hazard can be expressed as low-to-moderate. A geotechnical classification of the entire region is developed based on surface geology, available borehole data and morphotectonic constraints. Frequency-dependent amplification factors, consistent with code values, are proposed. The northern and southern parts of the region are characterized by stiff and soft soils respectively, being the softest soils located along river valleys. Seismic hazard maps including soil effects are obtained by applying these factors to the seismic hazard maps
Next generation seismic fragility curves for California bridges incorporating the evolution in seismic design philosophy
Ramanathan, Karthik Narayan
Quantitative and qualitative assessment of the seismic risk to highway bridges is crucial in pre-earthquake planning, and post-earthquake response of transportation systems. Such assessments provide valuable knowledge about a number of principal effects of earthquakes such as traffic disruption of the overall highway system, impact on the regions’ economy and post-earthquake response and recovery, and more recently serve as measures to quantify resilience. Unlike previous work, this study captures unique bridge design attributes specific to California bridge classes along with their evolution over three significant design eras, separated by the historic 1971 San Fernando and 1989 Loma Prieta earthquakes (these events affected changes in bridge seismic design philosophy). This research developed next-generation fragility curves for four multispan concrete bridge classes by synthesizing new knowledge and emerging modeling capabilities, and by closely coordinating new and ongoing national research initiatives with expertise from bridge designers. A multi-phase framework was developed for generating fragility curves, which provides decision makers with essential tools for emergency response, design, planning, policy support, and maximizing investments in bridge retrofit. This framework encompasses generational changes in bridge design and construction details. Parameterized high-fidelity three-dimensional nonlinear analytical models are developed for the portfolios of bridge classes within different design eras. These models incorporate a wide range of geometric and material uncertainties, and their responses are characterized under seismic loadings. Fragility curves were then developed considering the vulnerability of multiple components and thereby help to quantify the performance of highway bridge networks and to study the impact of seismic design principles on the performance within a bridge class. This not only leads to the development of fragility relations
Seismic hazard assessment: Issues and alternatives
Wang, Z.
Seismic hazard and risk are two very important concepts in engineering design and other policy considerations. Although seismic hazard and risk have often been used inter-changeably, they are fundamentally different. Furthermore, seismic risk is more important in engineering design and other policy considerations. Seismic hazard assessment is an effort by earth scientists to quantify seismic hazard and its associated uncertainty in time and space and to provide seismic hazard estimates for seismic risk assessment and other applications. Although seismic hazard assessment is more a scientific issue, it deserves special attention because of its significant implication to society. Two approaches, probabilistic seismic hazard analysis (PSHA) and deterministic seismic hazard analysis (DSHA), are commonly used for seismic hazard assessment. Although PSHA has been pro-claimed as the best approach for seismic hazard assessment, it is scientifically flawed (i.e., the physics and mathematics that PSHA is based on are not valid). Use of PSHA could lead to either unsafe or overly conservative engineering design or public policy, each of which has dire consequences to society. On the other hand, DSHA is a viable approach for seismic hazard assessment even though it has been labeled as unreliable. The biggest drawback of DSHA is that the temporal characteristics (i.e., earthquake frequency of occurrence and the associated uncertainty) are often neglected. An alternative, seismic hazard analysis (SHA), utilizes earthquake science and statistics directly and provides a seismic hazard estimate that can be readily used for seismic risk assessment and other applications. ?? 2010 Springer Basel AG.
Downhole hydraulic seismic generator
Gregory, Danny L.; Hardee, Harry C.; Smallwood, David O.
A downhole hydraulic seismic generator system for transmitting energy wave vibrations into earth strata surrounding a borehole. The system contains an elongated, unitary housing operably connected to a well head aboveground by support and electrical cabling, and contains clamping apparatus for selectively clamping the housing to the walls of the borehole. The system further comprises a hydraulic oscillator containing a double-actuating piston whose movement is controlled by an electro-servovalve regulating a high pressure hydraulic fluid flow into and out of upper and lower chambers surrounding the piston. The spent hydraulic fluid from the hydraulic oscillator is stored and pumped back into the system to provide high pressure fluid for conducting another run at the same, or a different location within the borehole.
Seismic instrumentation of buildings
Çelebi, Mehmet
The purpose of this report is to provide information on how and why we deploy seismic instruments in and around building structures. The recorded response data from buildings and other instrumented structures can be and are being primarily used to facilitate necessary studies to improve building codes and therefore reduce losses of life and property during damaging earthquakes. Other uses of such data can be in emergency response situations in large urban environments. The report discusses typical instrumentation schemes, existing instrumentation programs, the steps generally followed in instrumenting a structure, selection and type of instruments, installation and maintenance requirements and data retrieval and processing issues. In addition, a summary section on how recorded response data have been utilized is included. The benefits from instrumentation of structural systems are discussed.
Artificial seismic acceleration
Felzer, Karen R.; Page, Morgan T.; Michael, Andrew J.
In their 2013 paper, Bouchon, Durand, Marsan, Karabulut, 3 and Schmittbuhl (BDMKS) claim to see significant accelerating seismicity before M 6.5 interplate mainshocks, but not before intraplate mainshocks, reflecting a preparatory process before large events. We concur with the finding of BDMKS that their interplate dataset has significantly more fore- shocks than their intraplate dataset; however, we disagree that the foreshocks are predictive of large events in particular. Acceleration in stacked foreshock sequences has been seen before and has been explained by the cascade model, in which earthquakes occasionally trigger aftershocks larger than themselves4. In this model, the time lags between the smaller mainshocks and larger aftershocks follow the inverse power law common to all aftershock sequences, creating an apparent acceleration when stacked (see Supplementary Information).

System One, a digital radiography system, incorporates a reusable image medium (RIM) which retains an image. No film is needed; the RIM is read with a laser scanner, and the information is used to produce a digital image on an image processor. The image is stored on an optical disc. System allows the radiologist to "dial away" unwanted images to compare views on three screens. It is compatible with existing equipment and cost efficient. It was commercialized by a Stanford researcher from energy selective technology developed under a NASA grant.
Transdimensional Seismic Tomography
Bodin, T.; Sambridge, M.
In seismic imaging the degree of model complexity is usually determined by manually tuning damping parameters within a fixed parameterization chosen in advance. Here we present an alternative methodology for seismic travel time tomography where the model complexity is controlled automatically by the data. In particular we use a variable parametrization consisting of Voronoi cells with mobile geometry, shape and number, all treated as unknowns in the inversion. The reversible jump algorithm is used to sample the transdimensional model space within a Bayesian framework which avoids global damping procedures and the need to tune regularisation parameters. The method is an ensemble inference approach, as many potential solutions are generated with variable numbers of cells. Information is extracted from the ensemble as a whole by performing Monte Carlo integration to produce the expected Earth model. The ensemble of models can also be used to produce velocity uncertainty estimates and experiments with synthetic data suggest they represent actual uncertainty surprisingly well. In a transdimensional approach, the level of data uncertainty directly determines the model complexity needed to satisfy the data. Intriguingly, the Bayesian formulation can be extended to the case where data uncertainty is also uncertain. Experiments show that it is possible to recover data noise estimate while at the same time controlling model complexity in an automated fashion. The method is tested on synthetic data in a 2-D application and compared with a more standard matrix based inversion scheme. The method has also been applied to real data obtained from cross correlation of ambient noise where little is known about the size of the errors associated with the travel times. As an example, a tomographic image of Rayleigh wave group velocity for the Australian continent is constructed for 5s data together with uncertainty estimates.
Seismic efficiency of meteor airbursts
Svetsov, V. V.; Artemieva, N. A.; Shuvalov, V. V.
We present the results of numerical simulation for impacts of relatively small asteroids and ice bodies of 30-100 m in size, decelerated in the atmosphere and exploding before they reach the surface, but still producing seismic effects due to the impact wave reaching the surface. The calculated magnitudes fall within the range of 4 to 6, and average seismic efficiency of these events is 2.5 × 10-5. The results obtained allow the seismic hazard from impacts of cosmic bodies to be estimated.
The seismic traffic footprint: Tracking trains, aircraft, and cars seismically
Riahi, Nima; Gerstoft, Peter
Although naturally occurring vibrations have proven useful to probe the subsurface, the vibrations caused by traffic have not been explored much. Such data, however, are less sensitive to weather and low visibility compared to some common out-of-road traffic sensing systems. We study traffic-generated seismic noise measured by an array of 5200 geophones that covered a 7 × 10 km area in Long Beach (California, USA) with a receiver spacing of 100 m. This allows us to look into urban vibrations below the resolution of a typical city block. The spatiotemporal structure of the anthropogenic seismic noise intensity reveals the Blue Line Metro train activity, departing and landing aircraft in Long Beach Airport and their acceleration, and gives clues about traffic movement along the I-405 highway at night. As low-cost, stand-alone seismic sensors are becoming more common, these findings indicate that seismic data may be useful for traffic monitoring.
Expected Seismicity and the Seismic Noise Environment of Europa
Panning, Mark P.; Stähler, Simon C.; Huang, Hsin-Hua; Vance, Steven D.; Kedar, Sharon; Tsai, Victor C.; Pike, William T.; Lorenz, Ralph D.
Seismic data will be a vital geophysical constraint on internal structure of Europa if we land instruments on the surface. Quantifying expected seismic activity on Europa both in terms of large, recognizable signals and ambient background noise is important for understanding dynamics of the moon, as well as interpretation of potential future data. Seismic energy sources will likely include cracking in the ice shell and turbulent motion in the oceans. We define a range of models of seismic activity in Europa's ice shell by assuming each model follows a Gutenberg-Richter relationship with varying parameters. A range of cumulative seismic moment release between 1016 and 1018 Nm/yr is defined by scaling tidal dissipation energy to tectonic events on the Earth's moon. Random catalogs are generated and used to create synthetic continuous noise records through numerical wave propagation in thermodynamically self-consistent models of the interior structure of Europa. Spectral characteristics of the noise are calculated by determining probabilistic power spectral densities of the synthetic records. While the range of seismicity models predicts noise levels that vary by 80 dB, we show that most noise estimates are below the self-noise floor of high-frequency geophones but may be recorded by more sensitive instruments. The largest expected signals exceed background noise by ˜50 dB. Noise records may allow for constraints on interior structure through autocorrelation. Models of seismic noise generated by pressure variations at the base of the ice shell due to turbulent motions in the subsurface ocean may also generate observable seismic noise.
Progressive Seismic Failure, Seismic Gap, and Great Seismic Risk across the Densely Populated North China Basin
Yin, A.; Yu, X.; Shen, Z.
Although the seismically active North China basin has the most complete written records of pre-instrumentation earthquakes in the world, this information has not been fully utilized for assessing potential earthquake hazards of this densely populated region that hosts ~200 million people. In this study, we use the historical records to document the earthquake migration pattern and the existence of a 180-km seismic gap along the 600-km long right-slip Tangshan-Hejian-Cixian (THC) fault zone that cuts across the North China basin. The newly recognized seismic gap, which is centered at Tianjin with a population of 11 million people and ~120 km from Beijing (22 million people) and Tangshan (7 million people), has not been ruptured in the past 1000 years by M≥6 earthquakes. The seismic migration pattern in the past millennium suggests that the epicenters of major earthquakes have shifted towards this seismic gap along the THC fault, which implies that the 180- km gap could be the site of the next great earthquake with M≈7.6 if it is ruptured by a single event. Alternatively, the seismic gap may be explained by aseismic creeping or seismic strain transfer between active faults.

Alaska Seismic Network Upgrade and Expansion
Sandru, J. M.; Hansen, R. A.; Estes, S. A.; Fowler, M.
AEIC (Alaska Earthquake Information Center) has begun the task of upgrading the older regional seismic monitoring sites that have been in place for a number of years. Many of the original sites (some dating to the 1960's) are still single component analog technology. This was a very reasonable and ultra low power reliable system for its day. However with the advanced needs of today's research community, AEIC has begun upgrading to Broadband and Strong Motion Seismometers, 24 bit digitizers and high-speed two-way communications, while still trying to maintain the utmost reliability and maintaining low power consumption. Many sites have been upgraded or will be upgraded from single component to triaxial broad bands and triaxial accerometers. This provided much greater dynamic range over the older antiquated technology. The challenge is compounded by rapidly changing digital technology. Digitizersand data communications based on analog phone lines utilizing 9600 baud modems and RS232 are becoming increasingly difficult to maintain and increasingly expensive compared to current methods that use Ethernet, TCP/IP and UDP connections. Gaining a reliable Internet connection can be as easy as calling up an ISP and having a DSL connection installed or may require installing our own satellite uplink, where other options don't exist. LANs are accomplished with a variety of communications devices such as spread spectrum 900 MHz radios or VHF radios for long troublesome shots. WANs are accomplished with a much wider variety of equipment. Traditional analog phone lines are being used in some instances, however 56K lines are much more desirable. Cellular data links have become a convenient option in semiurban environments where digital cellular coverage is available. Alaska is slightly behind the curve on cellular technology due to its low population density and vast unpopulated areas but has emerged into this new technology in the last few years.

Non-seismic tsunamis: filling the forecast gap
Moore, C. W.; Titov, V. V.; Spillane, M. C.
Earthquakes are the generation mechanism in over 85% of tsunamis. However, non-seismic tsunamis, including those generated by meteorological events, landslides, volcanoes, and asteroid impacts, can inundate significant area and have a large far-field effect. The current National Oceanographic and Atmospheric Administration (NOAA) tsunami forecast system falls short in detecting these phenomena. This study attempts to classify the range of effects possible from these non-seismic threats, and to investigate detection methods appropriate for use in a forecast system. Typical observation platforms are assessed, including DART bottom pressure recorders and tide gauges. Other detection paths include atmospheric pressure anomaly algorithms for detecting meteotsunamis and the early identification of asteroids large enough to produce a regional hazard. Real-time assessment of observations for forecast use can provide guidance to mitigate the effects of a non-seismic tsunami.

Pole tide triggering of seismicity
Gorshkov, V.
The influence of the pole tide (PT) on intensity of seismic process is searched on base of Harvard Centroid-moment tensors catalogue (CMT). The normal and shear stresses excited by PT were calculated for each earthquake (EQ) from CMT (32.3 thousands of EQ events after for- and aftershock declustering). There was revealed that there are two maxima of PT influence on weak (less 5.5 magnitudes) thrust-slip EQ near the both extrema (min and max) of shear stress. This influence has 95 % level of statistical significance by Schuster and χ^2 criteria and could explain the 0.6-year periodicity in seismic intensity spectrum. The PT influence on seismicity becomes negligible when PT variations decrease up to 100~mas. This could explain 6-7 years periodicity in seismic intensity spectrum.
Description and Preliminary Testing of the CDSN Seismic Sensor Systems
Peterson, Jon; Tilgner, Edwin E.
INTRODUCTION The China Digital Seismograph Network (CDSN) is being designed and installed to provide the People's Republic of China with the facilities needed to create a national digital database for earthquake research. The CDSN, which is being developed jointly by the PRC State Seismological Bureau and the U.S. Geological Survey, will consist initially of nine digitally-recording seismograph stations, a data management system to be used for compiling network-day tapes, and a depot maintenance center. Data produced by the network will be shared with research scientists throughout the world. A national seismograph network must be designed to support a variety of research objectives. From this standpoint, the choices and tradeoffs involved in specifying signal bandwidth, resolution, and dynamic range are the most important decisions in system design. As in the case of the CDSN, these decisions are made during the selection and design of the seismic sensor system and encoder components. The purpose of this report is to describe the CDSN sensor systems, their important signal characteristics, and the results of preliminary tests that have been performed on the instruments. Four overlapping data bands will be recorded at each station: short period (SP), broadband (BB), long period (LP), and very long period (VLP). Amplitude response curves are illustrated in Figure I. Vertical and horizontal components will be recorded for each data band. The SP and LP channels will be recorded with sufficient sensitivities to resolve earth background noise at seismically quiet sites. The BB channels will have a lower sensitivity and are intended for broadband recording of moderate-to-large body-wave signals and for increasing the effective amplitude range in the short- and long-period bands. The VLP channel does not provide additional spectral coverage at long periods; its purpose is to make use of on-site filtration and decimation to reduce post processing requirements for VLP
Accessing seismic data through geological interpretation: Challenges and solutions
Butler, R. W.; Clayton, S.; McCaffrey, B.
Between them, the world's research programs, national institutions and corporations, especially oil and gas companies, have acquired substantial volumes of seismic reflection data. Although the vast majority are proprietary and confidential, significant data are released and available for research, including those in public data libraries. The challenge now is to maximise use of these data, by providing routes to seismic not simply on the basis of acquisition or processing attributes but via the geology they image. The Virtual Seismic Atlas (VSA: www.seismicatlas.org) meets this challenge by providing an independent, free-to-use community based internet resource that captures and shares the geological interpretation of seismic data globally. Images and associated documents are explicitly indexed by extensive metadata trees, using not only existing survey and geographical data but also the geology they portray. The solution uses a Documentum database interrogated through Endeca Guided Navigation, to search, discover and retrieve images. The VSA allows users to compare contrasting interpretations of clean data thereby exploring the ranges of uncertainty in the geometric interpretation of subsurface structure. The metadata structures can be used to link reports and published research together with other data types such as wells. And the VSA can link to existing data libraries. Searches can take different paths, revealing arrays of geological analogues, new datasets while providing entirely novel insights and genuine surprises. This can then drive new creative opportunities for research and training, and expose the contents of seismic data libraries to the world.
Seismic Characterization of the Newberry and Cooper Basin EGS Sites
Templeton, D. C.; Wang, J.; Goebel, M.; Johannesson, G.; Myers, S. C.; Harris, D.; Cladouhos, T. T.
To aid in the seismic characterization of Engineered Geothermal Systems (EGS), we enhance traditional microearthquake detection and location methodologies at two EGS systems: the Newberry EGS site and the Habanero EGS site in the Cooper Basin of South Australia. We apply the Matched Field Processing (MFP) seismic imaging technique to detect new seismic events using known discrete microearthquake sources. Events identified using MFP typically have smaller magnitudes or occur within the coda of a larger event. Additionally, we apply a Bayesian multiple-event location algorithm, called MicroBayesLoc, to estimate the 95% probability ellipsoids for events with high signal-to-noise ratios (SNR). Such probability ellipsoid information can provide evidence for determining if a seismic lineation is real, or simply within the anticipated error range. At the Newberry EGS site, 235 events were reported in the original catalog. MFP identified 164 additional events (an increase of over 70% more events). For the relocated events in the Newberry catalog, we can distinguish two distinct seismic swarms that fall outside of one another's 95% probability error ellipsoids.This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.

Ambient seismic noise monitoring of the Super-Sauze landslide from a very dense temporary seismic array
Chtouki, Toufik; Vergne, Jerome; Provost, Floriane; Malet, Jean-Philippe; Burtin, Arnaud; Hibert, Clément
The Super-Sauze landslide is located on the southern part of the Barcelonnette Basin (French Alps) and has developed in a soft clay-shale environment. It is one of the four sites continuously monitored through a wide variety of geophysical and hydro-geological techniques in the framework of the OMIV French national landslide observatory. From early June to mid-July 2016, a temporary dense seismic array has been installed in the most active part of the landslide and at its surroundings. 50 different sites with an average inter-station distance of 50m have been instrumented with 150 miniaturized and autonomous seismic stations (Zland nodes), allowing a continuous record of the seismic signal at frequencies higher than 0.2Hz over an almost regular grid. Concurrently, a Ground-Based InSAR device allowed for a precise and continuous monitoring of the surface deformation. Overall, this experiment is intended to better characterize the spatio-temporal evolution of the deformation processes related to various type of forcing. We analyze the continuous records of ambient seismic noise recorded by the dense array. Using power spectral densities, we characterize the various types of natural and anthropogenic seismic sources, including the effect of water turbulence and bedload transport in the small nearby torrents. We also compute the correlation of the ambient diffuse seismic noise in various frequency bands for the 2448 station pairs to recover the empirical Green functions between them. The temporal evolution of the coda part of these noise correlation functions allows monitoring and localizing shear wave velocity variations in the sliding mass. Here we present some preliminary results of this analysis and compare the seismic variations to meteorological data and surface deformation.
Older people and digital disengagement: a fourth digital divide?
Olphert, Wendy; Damodaran, Leela
Digital technologies are becoming more pervasive in all areas of society. Enabling everyone to have access and capability to use the Internet and associated digital technologies, summed up in the term 'digital inclusion', is seen to have wide-ranging benefits to the individual, to the economy and to society. For older people, being digitally included can help them to maintain their independence, social connectedness and sense of worth in the face of declining health or limited capabilities, as well as also offering new opportunities to improve their quality of life. At present however, access to the technology and to the benefits is not equally distributed either between or within nations, and older people tend to be on the 'wrong' side of what is termed the 'digital divide'. Governments globally are developing strategies to promote digital inclusion and indeed Internet uptake is increasing steadily, including amongst older people. However, such strategies have focussed on getting people online, and there appears to be an assumption that once someone is online they will remain 'digitally engaged'. In fact statistics show that some users give up using the Internet, and there is emerging evidence that older people are more vulnerable to the factors which can lead to this outcome. The authors see this phenomenon as a potential but largely unrecognised 'fourth digital divide' which has serious implications for social inclusion. The objectives of this article are (a) to raise awareness of the phenomenon of digital disengagement by considering some of the emerging evidence, (b) to explore some of the potential implications of not recognising and therefore not addressing the needs of the digitally disengaged older population, and (c) to reveal the prevailing gap in knowledge which future research should address.

Visualization of volumetric seismic data
Spickermann, Dela; Böttinger, Michael; Ashfaq Ahmed, Khawar; Gajewski, Dirk
Mostly driven by demands of high quality subsurface imaging, highly specialized tools and methods have been developed to support the processing, visualization and interpretation of seismic data. 3D seismic data acquisition and 4D time-lapse seismic monitoring are well-established techniques in academia and industry, producing large amounts of data to be processed, visualized and interpreted. In this context, interactive 3D visualization methods proved to be valuable for the analysis of 3D seismic data cubes - especially for sedimentary environments with continuous horizons. In crystalline and hard rock environments, where hydraulic stimulation techniques may be applied to produce geothermal energy, interpretation of the seismic data is a more challenging problem. Instead of continuous reflection horizons, the imaging targets are often steep dipping faults, causing a lot of diffractions. Without further preprocessing these geological structures are often hidden behind the noise in the data. In this PICO presentation we will present a workflow consisting of data processing steps, which enhance the signal-to-noise ratio, followed by a visualization step based on the use the commercially available general purpose 3D visualization system Avizo. Specifically, we have used Avizo Earth, an extension to Avizo, which supports the import of seismic data in SEG-Y format and offers easy access to state-of-the-art 3D visualization methods at interactive frame rates, even for large seismic data cubes. In seismic interpretation using visualization, interactivity is a key requirement for understanding complex 3D structures. In order to enable an easy communication of the insights gained during the interactive visualization process, animations of the visualized data were created which support the spatial understanding of the data.

Generalized model of seismic pulse
Rabinovich, E. V.; Filipenko, N. Y.; Shefel, G. S.
The paper presents data on a pulse model, suitable for generalizing models of known seismic pulses. It is shown that for each of the known models it is possible to obtain a very accurate quadratic approximation using the proposed model. For example, the fragment of a real seismic trace is approximated by a pulses set formed on the basis of the proposed model, with a high accuracy.
Seismic risk perception in Italy
Crescimbene, Massimo; La Longa, Federica; Camassi, Romano; Pino, Nicola Alessandro; Peruzza, Laura
Risk perception is a fundamental element in the definition and the adoption of preventive counter-measures. In order to develop effective information and risk communication strategies, the perception of risks and the influencing factors should be known. This paper presents results of a survey on seismic risk perception in Italy conducted from January 2013 to present . The research design combines a psychometric and a cultural theoretic approach. More than 7,000 on-line tests have been compiled. The data collected show that in Italy seismic risk perception is strongly underestimated; 86 on 100 Italian citizens, living in the most dangerous zone (namely Zone 1), do not have a correct perception of seismic hazard. From these observations we deem that extremely urgent measures are required in Italy to reach an effective way to communicate seismic risk. Finally, the research presents a comparison between groups on seismic risk perception: a group involved in campaigns of information and education on seismic risk and a control group.
Quantifying the seismicity on Taiwan
Wu, Yi-Hsuan; Chen, Chien-Chih; Turcotte, Donald L.; Rundle, John B.
We quantify the seismicity on the island of Taiwan using the frequency-magnitude statistics of earthquakes since 1900. A break in Gutenberg-Richter scaling for large earthquakes in global seismicity has been observed, this break is also observed in our Taiwan study. The seismic data from the Central Weather Bureau Seismic Network are in good agreement with the Gutenberg-Richter relation taking b ≈ 1 when M < 7. For large earthquakes, M ≥ 7, the seismic data fit Gutenberg-Richter scaling with b ≈ 1.5. If the Gutenberg-Richter scaling for M < 7 earthquakes is extrapolated to larger earthquakes, we would expect a M > 8 earthquake in the study region about every 25 yr. However, our analysis shows a lower frequency of occurrence of large earthquakes so that the expected frequency of M > 8 earthquakes is about 200 yr. The level of seismicity for smaller earthquakes on Taiwan is about 12 times greater than in Southern California and the possibility of a M ≈ 9 earthquake north or south of Taiwan cannot be ruled out. In light of the Fukushima, Japan nuclear disaster, we also discuss the implications of our study for the three operating nuclear power plants on the coast of Taiwan.
Advances through collaboration: sharing seismic reflection data via the Antarctic Seismic Data Library System for Cooperative Research (SDLS)
Wardell, N.; Childs, J. R.; Cooper, A. K.
The Antarctic Seismic Data Library System for Cooperative Research (SDLS) has served for the past 16 years under the auspices of the Antarctic Treaty (ATCM Recommendation XVI-12) as a role model for collaboration and equitable sharing of Antarctic multichannel seismic reflection (MCS) data for geoscience studies. During this period, collaboration in MCS studies has advanced deciphering the seismic stratigraphy and structure of Antarctica’s continental margin more rapidly than previously. MCS data compilations provided the geologic framework for scientific drilling at several Antarctic locations and for high-resolution seismic and sampling studies to decipher Cenozoic depositional paleoenvironments. The SDLS successes come from cooperation of National Antarctic Programs and individual investigators in “on-time� submissions of their MCS data. Most do, but some do not. The SDLS community has an International Polar Year (IPY) goal of all overdue MCS data being sent to the SDLS by end of IPY. The community science objective is to compile all Antarctic MCS data to derive a unified seismic stratigraphy for the continental margin – a stratigraphy to be used with drilling data to derive Cenozoic circum-Antarctic paleobathymetry maps and local-to-regional scale paleoenvironmental histories.
Improving the Detectability of the Catalan Seismic Network for Local Seismic Activity Monitoring
Jara, Jose Antonio; Frontera, Tà nit; Batlló, Josep; Goula, Xavier
The seismic survey of the territory of Catalonia is mainly performed by the regional seismic network operated by the Cartographic and Geologic Institute of Catalonia (ICGC). After successive deployments and upgrades, the current network consists of 16 permanent stations equipped with 3 component broadband seismometers (STS2, STS2.5, CMG3ESP and CMG3T), 24 bits digitizers (Nanometrics Trident) and VSAT telemetry. Data are continuously sent in real-time via Hispasat 1D satellite to the ICGC datacenter in Barcelona. Additionally, data from other 10 stations of neighboring areas (Spain, France and Andorra) are continuously received since 2011 via Internet or VSAT, contributing both to detect and to locate events affecting the region. More than 300 local events with Ml ≥ 0.7 have been yearly detected and located in the region. Nevertheless, small magnitude earthquakes, especially those located in the south and south-west of Catalonia may still go undetected by the automatic detection system (DAS), based on Earthworm (USGS). Thus, in order to improve the detection and characterization of these missed events, one or two new stations should be installed. Before making the decision about where to install these new stations, the performance of each existing station is evaluated taking into account the fraction of detected events using the station records, compared to the total number of events in the catalogue, occurred during the station operation time from January 1, 2011 to December 31, 2014. These evaluations allow us to build an Event Detection Probability Map (EDPM), a required tool to simulate EDPMs resulting from different network topology scenarios depending on where these new stations are sited, and becoming essential for the decision-making process to increase and optimize the event detection probability of the seismic network.
Noise analysis of the seismic system employed in the northern and southern California seismic nets
Eaton, J.P.
The seismic networks have been designed and operated to support recording on Develocorders (less than 40db dynamic range) and analog magnetic tape (about 50 db dynamic range). The principal analysis of the records has been based on Develocorder films; and background earth noise levels have been adjusted to be about 1 to 2 mm p-p on the film readers. Since the traces are separated by only 10 to 12 mm on the reader screen, they become hopelessly tangled when signal amplitudes on several adjacent traces exceed 10 to 20 mm p-p. Thus, the background noise level is hardly more than 20 db below the level of largest readable signals. The situation is somewhat better on tape playbacks, but the high level of background noise set to accomodate processing from film records effectively limits the range of maximum-signal to background-earth-noise on high gain channels to a little more than 30 db. Introduction of the PDP 11/44 seismic data acquisition system has increased the potential dynamic range of recorded network signals to more than 60 db. To make use of this increased dynamic range we must evaluate the characteristics and performance of the seismic system. In particular, we must determine whether the electronic noise in the system is or can be made sufficiently low so that background earth noise levels can be lowered significantly to take advantage of the increased dynamic range of the digital recording system. To come to grips with the complex problem of system noise, we have carried out a number of measurements and experiments to evaluate critical components of the system as well as to determine the noise characteristics of the system as a whole.
Digital geologic map and database of the Chesapeake and Ohio Canal National Historical Park and Potomac River corridor, District of Columbia, Virginia, Maryland, and West Virginia
Southworth, C. Scott; Brezinski, David K.; Orndorff, Randall C.; Chirico, Peter G.; Lagueux, Kerry M.
The Chesapeake and Ohio (CO) Canal National Historical Park is unique in that it is the only land within the National Park system that crosses 5 physiographic provinces along a major river. From Georgetown, District of Columbia (D.C.) to Cumberland, Maryland (Md.), the CO Canal provides an opportunity to examine the geologic history of the central Appalachian region and how the canal contributed to the development of this area. The geologic map data covers the 184.5-mile long park in a 2-mile wide corridor centered on the Potomac River
Seismic signature of crustal magma and fluid from deep seismic sounding data across Tengchong volcanic area
Bai, Z. M.; Zhang, Z. Z.; Wang, C. Y.; Klemperer, S. L.
. There are typical tectonic and deep origin mechanisms for the moderate-strong earthquakes nearby SP Tuantian, and precaution should be added on this area in case of the potential earthquake. Our fusion image also clearly revealed that there exist two remarkable positions on the Moho discontinuity through which the heat from the upper mantle was transmitted upward, and this is attributed to the widely distributed hot material within the crust and upper mantle.

Digital hum filtering
Knapp, R.W.; Anderson, N.L.
Data may be overprinted by a steady-state cyclical noise (hum). Steady-state indicates that the noise is invariant with time; its attributes, frequency, amplitude, and phase, do not change with time. Hum recorded on seismic data usually is powerline noise and associated higher harmonics; leakage from full-waveform rectified cathodic protection devices that contain the odd higher harmonics of powerline frequencies; or vibrational noise from mechanical devices. The fundamental frequency of powerline hum may be removed during data acquisition with the use of notch filters. Unfortunately, notch filters do not discriminate signal and noise, attenuating both. They also distort adjacent frequencies by phase shifting. Finally, they attenuate only the fundamental mode of the powerline noise; higher harmonics and frequencies other than that of powerlines are not removed. Digital notch filters, applied during processing, have many of the same problems as analog filters applied in the field. The method described here removes hum of a particular frequency. Hum attributes are measured by discrete Fourier analysis, and the hum is canceled from the data by subtraction. Errors are slight and the result of the presence of (random) noise in the window or asynchrony of the hum and data sampling. Error is minimized by increasing window size or by resampling to a finer interval. Errors affect the degree of hum attenuation, not the signal. The residual is steady-state hum of the same frequency. ?? 1994.

3DNES Brings Your Nostalgia to the Third Dimension
Recently, a company named Geod Studio released an experimental 3D NES emulator, aptly named 3DNES. The emulator adds depth to sprites and...
By Casp · Mar 12, 2016
Sprites, pixel art, and 2D games are a thing of the past, much like landlines, newspapers, and chivalry. In this age of hyper-realism, games of simple design are few and far in between, and they are primarily used as gimmicks. With good reason, too; the games of old just look foolish in comparison to the titans of today. Go ahead, fire up your NES and relish how archaic it all looks. Sure, at the time it pushed the limits of the gaming market, but now it just looks silly. That, however, is where Geod Studio comes in with the 3DNES to make your obsolete graphics look fashionable again. Your nostalgia lives another day free from the cold, dead hands of impending reality.
3DNES is an NES emulator that converts all of your favourite titles into 3D, as the name implies. The emulator uses an algorithm to add depth to sprites and background images, and it does a little more than simply stretch the sprites onto another axis, as circles are converted into spheres. It appears to separate images from the background renders, which looks relatively clunky with the NES-style graphics. Although this functions well enough for more simply-designed games, such as Super Mario Bros., more complex games don't fare as well. Since anyone can use the emulator if they have a ROM ready to go and Firefox (yes, the emulator only works on Firefox), I decided to try this for a spin.
Since I heard Super Mario Bros. is the best-looking game on this emulator, I decided to see how well this worked. Considering the backgrounds are simple and are clearly separated from the interactive objects in the worlds, it was quite clear what Geod Studio had in mind with this project, but it is obviously still a work in progress. Some polygons wouldn't fully render and Mario occasionally had half-a-face. Sometimes enemies wouldn't render at all, and I would be killed by what appeared to be nothing. Sounds and music were occasionally bit-crushed (accidentally, I'm pretty sure) or they were distorted to a point where they sounded like they belonged in a poorly-assembled MLG montage parody. Some objects appear to be stretched out and are in focus at the forefront of each frame, but backgrounds occasionally seem to exhibit some kind of motion blur. The algorithm was not very kind to a lot of these sprites.
Obviously, this project is nowhere near finished, and Geod Studio hopes to improve the functionality of games on this platform through subsequent beta releases. Trần Vũ Trúc of Geod Studio has plans to give each individual game the ability to be heavily personalized by its players, although this is definitely very far away. If all goes according to Geod's plans, then this beta will be the only release through this WebGL Unity Player platform, and all future releases will be available in an executable format.
Although the 3DNES is nowhere near the update your nostalgia so desperately needs, it's definitely a start. It appears that Geod has very ambitious plans for this emulator, and if they continue as planned, this project should be nothing short of revolutionary. The games look terrible, there is no arguing that, but they do function as they're supposed to. Maybe with a little more money and a little more time, the 3DNES will begin a trend of emulators that successfully imitate the inherent nostalgia that comes with playing your favourite NES game, while also providing a contemporary twist to hold the experience together. For now, though, it's in a sad, shriveled state, and it's probably best if you just wait for further news.
My writing sucks.

Nintendo Announces New Hardware Concept and Mobile Gaming Plans
By Sparfire · Mar 17, 2015
Nintendo's president Satoru Iwata just confirmed the development of a new next-generation hardware concept, currently named "The NX." At the same event he also revealed a partnership with a major Japanese mobile games company, DeNA. This means that Mario, Zelda and all your favorites finally might show up in mobile games soon. However, the president was very clear on the fact that no current games will be ported over, as they are not designed for mobile at all. New games based on all Nintendo's IP's are available for DeNA to create new original games from, that will suit the mobile gaming more than a direct port could. Nintendo will also be making their own games for mobile, presented on the market through their new partner.
"As proof that Nintendo maintains strong enthusiasm for the dedicated game system business, let me confirm that Nintendo is currently developing a dedicated game platform with a brand-new concept under the development codename 'NX.' It is too early to elaborate on the details of this project, but we hope to share more information with you next year."
Now, they are not specifying much here, whether or not this hardware is a console or something else remains to be seen. But as seen in the graphic below, it is pictured next to the Wii-U and the 3DS, which hints towards a console of some sorts, but that is of course nothing but unfounded speculation.
Iwata also stated that a new service will be launching this fall, intended to connect Nintendo to their users regardless of platform, and replace the recently discontinued Club Nintendo. This service will be made in cooperation with DeNA, according to the announcement.
"Nintendo, together with DeNA, will jointly develop a new membership service which encompasses the existing Nintendo 3DS and Wii U systems, the new hardware system with a brand-new concept, NX, and smart devices and PCs, and Nintendo will be the primary party to operate this new membership service."
What do you think the "NX" might be? More importantly, what would you like it to be? Or are you maybe more excited to play Mario on your phone? Share your thoughts with the community!

Landline (Pre-Recorded Audio Player)
By Rainbow Rowell, Rebecca Lowman (Read by)
July 2014 Indie Next List
“Georgie McCool's professional dreams are coming true and she couldn't be happier, except that it means the slow implosion of her marriage is about to speed up. Georgie's husband, Neal, and their kids leave for Christmas while Georgie stays behind to work on her new TV show and she is left alone with memories of when things were better. Those memories almost become reality when she discovers that her mother's landline can connect her with Neal in 1998, before he proposed. Landline is an incredibly emotional, honest, and often hilarious look at a marriage on the brink and the choices that must be made when dreams aren't enough.”
