2024年3—6月中国大陆地区M≥4.0地震震源机制解测定

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2024年3月1日—6月30日发生在中国大陆地区的M≥4.0共59次地震震源机制解。结果显示逆断型18次，走滑型33次，正断型7次，未知型1次。

Abstract: In this paper, the regional full waveform inversion using the broadband waveforms recorded by China Seismic Network were conducted, and the focal mechanism solutions of the 59 earthquakes with M≥4.0 occurred in the mainland of China during March to June 2024 were obtained. The types of these focal mechanism solutions show 18 reverse faulting, 33 strike-slip faulting, 7 normal faulting and 1 odd earthquakes.
