Determination of the focal mechanism solutions of the earthquakes with MS≥4.0 occurred in the mainland of China during April to June 2022

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.
