2022年10月—2023年2月中国大陆地区<i<M</i<≥4.0地震震源机制解测定

Determination of focal mechanism solutions of the earthquakes with <i<M</i<≥4.0 occurred in the mainland of China during October 2022 to February 2023

  • 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10月1日—2023年2月28日发生在中国大陆地区的<i<M</i<≥4.0共46次地震的震源机制解以及2023年1月30日新疆沙雅<i<M</i<6.1地震的矩心位置和矩心偏移时间。结果显示逆断型15次,走滑型15次,正断型14次,未知型2次。

     

    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 46 earthquakes with <i<M</i<≥4.0 occurred in the mainland of China from October 2022 to February 2023 were obtained. The centroid location and time shift of the <i<M</i<6.1 Shaya, Xinjiang earthquake were determinated by a grid search in the horizontal plane. The types of these focal mechanism solutions show 15 reverse faulting, 15 strike-slip faulting, 14 normal faulting and 2 odd earthquakes.
