| Abstract: | An MS7.4 earthquake struck west China in Maduo county, Guoluo prefecture, Qinghai province on May 22, 2021, at 2:04 Beijing time (18:04 UTC on May 21, 2021), which broke the quiet period of Chinese mainland for 1382 days without earthquakes of magnitude 7 or higher. The analysis of the seismic data sequence would play an important role in the in-depth study of the Maduo earthquake and the Bayan Har block. The Institute of Geophysics, China Earthquake Administration (CEA), compiled observation data recorded through 57 broadband seismometers within 500 km of the earthquake epicenter and intended to share for further researches in earthquake science community. The shared dataset included waveforms of the event and its sequence with magnitudes of 3.0 or higher that occurred between May 22–31, 2021 with a sampling rate of 100 sps along with the continuous waveforms of 20 Hz and 100 Hz. Additionally, the seismic instrument response files also were shared. The event and continuous waveform records could be downloaded by submitting a request through the web platform of the Earthquake Science Data Center of the Institute of Geophysics, CEA (www.esdc.ac.cn). |
