| The **GEED dataset v1.0** is a comprehensive global earthquake evaluation dataset integrating high-quality seismic observations from multiple international networks. It comprises **92,219 three-component records** (60 s each) from SCEDC (33,128), NCEDC (16,069), NOA (33,897), IPGP (1,688), and STEAD (7,437). Each waveform is extracted from 10 s before to 50 s after the Pg phase (60 s total) without preprocessing (no demeaning, detrending, or filtering). Data selection criteria include phase-picking methodology, magnitude, epicentral distance, sampling rate, and SNR. All waveforms are stored in **HDF5 format** consistent with STEAD, accompanied by a CSV metadata file containing **35 attributes** (station, event, and arrival time information) linked via the trace_name field. The **38,061 local earthquakes** (epicentral distance < 100 km, predominantly < 20 km) were recorded by **1,747 stations** worldwide, with focal depths mostly shallower than 20 km and magnitudes ranging from **M1 to M6** (M1-M2 events being the most numerous). |
