| 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. |
