10 years of Japan Earthquake Data with P and S phase onset time

This is an earthquake database prepared from the K-NET dataset with added P and S wave ground-truth information. It contains 22119 earthquake event records from 1538 earthquakes during the year 1997-to 2006 and its corresponding metadata extracted from https://www.kyoshin.bosai.go.jp/. The metadata and raw waveform data are stored in a bson file named header.bson and accelerogram.bson respectively.

Every accelerogram record contains header information regarding earthquake source parameters viz., location, magnitude, origin time, and depth. Some derived information e..g, sensor location, source to sensor-site distance, Peak Ground Acceleration ( tri-axial PGA) at the sensor site, duration of waveforms, and P, S phase arrival times are included in the database for multi-parameter analysis.
