InSight Marsquake Catalog

Part of the Space Probe and Mission Datasets collection on Hugging Face.

Complete catalog of marsquakes detected by NASA InSight's SEIS seismometer on Mars, sourced from the IRIS Mars Event Service. Currently 2,715 seismic events.

Dataset description

NASA's InSight lander operated on Mars from November 2018 to December 2022, deploying the SEIS (Seismic Experiment for Interior Structure) seismometer — the first seismometer successfully placed on another planet. Over the course of the mission, SEIS detected over 1,300 marsquakes, revealing the internal structure of Mars for the first time.

This dataset contains the complete MQS catalog, including event times, locations (where determinable), magnitudes, and event type classifications ranging from low-frequency broadband events to super-high-frequency signals.

Schema

Column	Type	Description
event_id	string	MQS event identifier (e.g. "mqs2022wrzi")
event_time	datetime	Origin time of the seismic event (UTC)
latitude	float64	Event latitude on Mars (degrees, null if undetermined)
longitude	float64	Event longitude on Mars (degrees, null if undetermined)
depth_km	float64	Event depth in km (null if undetermined)
author	string	Author of the event origin
catalog	string	Source catalog identifier
contributor	string	Contributing agency
contributor_id	string	InSight sol-based event name (e.g. "S1415a")
mag_type	string	Magnitude type (MW, MbS, etc.)
magnitude	float64	Event magnitude
mag_author	string	Author of the magnitude estimate
event_location_name	string	Named region on Mars (e.g. "Elysium Southwest")
event_type	string	MQS event type classification (BROADBAND, LOW_FREQUENCY, etc.)
event_type_short	string	Short event type label (BB, LF, HF, VF, SF, 2.4Hz)

Quick stats

• 2,715 seismic events
• 672 with magnitude estimates
• 2,715 with location estimates
• 6 distinct event type classifications
• Date range: 2019-01-12 to 2022-11-19
• Strongest event: mqs2022isne (magnitude 4.6)

Usage

from datasets import load_dataset

ds = load_dataset("juliensimon/insight-marsquake-catalog", split="train")
df = ds.to_pandas()

# Events with known locations
located = df[df["latitude"].notna()]
print(f"{len(located):,} events with determined locations")

# Strongest marsquakes
strongest = df.nlargest(10, "magnitude")[["event_time", "magnitude", "event_type", "latitude", "longitude"]]

# Events by type
by_type = df["event_type"].value_counts()

# Events per year
df["year"] = df["event_time"].dt.year
by_year = df.groupby("year").size()
