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

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 26 earthquakes with M≥4.0 occurred in the mainland of China during August to October 2023 were obtained. The types of these focal mechanism solutions show 9 reverse faulting, 14 strike-slip faulting and 3 normal faulting.
