2022年7—9月中国大陆地区M≥4.0地震震源机制解测定

Determination of focal mechanism solutions of the earthquakes with M4.0 occurred in the mainland of China during July to September 2022

  • 摘要: 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2022年7月1日—9月30日发生在中国大陆地区的M≥4.0共18次地震的震源机制解以及2022年9月5日四川泸定M6.8地震的矩心位置和矩心偏移时间。结果显示逆断型6次,走滑型7次,正断型4次,未知型1次。

     

    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 18 earthquakes with M≥4.0 in the mainland of China from July 1 to September 30, 2022 were obtained. The centroid location and time shift of the M6.8 Luding, Sichuan earthquake were determinated by a grid search in the horizontal plane. The types of these focal mechanism solutions show 6 reverse faulting, 7 strike-slip faulting, 4 normal faulting and 1 unknown earthquakes.
