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4月1日—6月30日发生在中国大陆地区的MS≥4.0共24次地震的震源机制解。结果显示逆断型5次，走滑型17次，正断型2次。Abstract: In this paper, the regional full waveform inversion of the broadband waveforms from China Seismic Network were conducted, and the focal mechanism solutions of the 24 earthquakes with MS≥4.0 in the mainland of China from April 1 to June 30, 2022 were obtained. The types of these focal mechanism solutions show 5 reverse faulting, 17 strike-slip faulting and 2 normal faulting.
