| Description | Regional broadband and short-period waveform datasets are collected to detect and relocate earthquakes during the 2022 M6.8 Luding, Sichuan earthquake sequence. Local broadband and strong-motion waveform datasets are collected to invert focal mechanism solutions of the mainshock and/or some aftershocks. Local seismic broadband waveforms with 50 Hz were cut from 5 s before detected P-wave arrivals to 10 s after detected P-wave arrivals. These waveforms were recorded by 54 seismic broadband and short-period stations within 200 km epicenter distances. The dataset for earthquake detection includes used waveforms in miniseed format and result plots in jpeg format. Regional seismic broadband event waveforms with 100 Hz were selected for regional Wphase Inversion of the M6.8 mainshock. The epicenter distances of waveforms in SAC format range from 3.0 to 6.0 deg. Local seismic broadband waveforms with 100 Hz recorded by stations with ∆ < 350 km were used. The event waveforms in SAC format are available. Near-field strong-motion waveforms with 200 Hz by 24 stations are collected to investigate the coseismic rupture history of the mainshock. The strong-motion waveforms start 30 s before the origin time of the mainshock, and last more than 100 s. The event waveform files in dat format are available. |
