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2023年11月1日—2024年2月29日发生在中国大陆地区的M≥4.0共62次地震震源机制解。结果显示逆断型45次,走滑型13次,正断型3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 62 earthquakes with M≥4.0 occurred in the mainland of China during November 2023 to February 2024 were obtained. The types of these focal mechanism solutions show 45 reverse faulting, 13 strike-slip faulting, 3 normal faulting and 1 odd earthquakes.
