Determination of focal mechanism solutions of the earthquakes with M≥4.0 occurred in the mainland of China during March to July 2023

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 30 earthquakes with M≥4.0 occurred in the mainland of China during March to July 2023 were obtained. The types of these focal mechanism solutions show 7 reverse faulting, 14 strike-slip faulting, 8 normal faulting and 1 odd earthquake.
