2023年甘肃积石山6.2级地震震源位置测定

Determination of the source location of the 2023 Jishishan M6.2 earthquake in Gansu Province

  • 摘要: 基于地震P波到时,利用模拟退火法对积石山6.2级地震震源位置进行了测定,同时采用样本集合统计分析方法对测定结果的可靠性进行了定量评价。结果显示:积石山6.2级地震震源位置为(35.750°N,102.833°E),深度为12.0 km,在95%置信水平下,震源位置参数解的置信区间为(35.748°~35.753°N,102.830°~102.836°E),深度为6.8~16.9 km。

     

    Abstract: Based on the P-phase arrival time, we determined the source location of the Jishishan M6.2 earthquake with simulated annealing (SA) method, and quantitatively evaluated the reliability of the results using sample set statistical analysis method. The results show that the source location of the Jishishan M6.2 earthquake is (35.750°N, 102.833°E), at a depth of 12.0 km. At a 95% confidence level, the confidence interval for the parameter solution of the source location is (35.748°~35.753°N, 102.830°~102.936°E), at a depth of 6.8~16.9 km.
