2022年2—3月中国大陆地区MS≥4.0地震震源机制解测定

Determination of the focal mechanism solutions of the earthquakes with MS≥4.0 occurred in the mainland of China during February to March 2022

    摘要
  • 摘要: 本文利用中国地震台网记录的宽频带波形资料，采用近震全波形反演方法得到2022年2月1日—3月31日发生在中国大陆地区的MS≥4.0共20次地震的震源机制解。结果显示逆断型5次，走滑型14次，未知型1次。

     

    Abstract: In this paper, the regional full waveform inversion of the broadband waveforms from China Seismic Network are conducted, and the focal mechanism solutions of the 20 earthquakes with MS≥4.0 in the mainland of China from February 1 to March 31, 2022 are obtained. The types of these focal mechanism solutions show 5 reverse faulting, 14 strike-slip faulting and 1 unknown earthquakes.
