摘要
使用区域台网资料,采用CAP方法反演了 2023年12月18日甘肃省积石山6.2级地震的震源机制解,结果显示,该地震为逆冲型地震,与GCMT、GFZ和USGS的震源机制解基本一致.震源机制解节面Ⅱ的走向与积石山东缘断裂大致相同.
Abstract
The Cut-And-Paste(CAP)method is used to invert the focal mechanism solu-tion of the Ms6.2 earthquake that occurred on December 18,2023,in Jishishan,Gansu Province,using regional network data.The result demonstrates that the earthquake is of the thrust type,which is consistent with the solutions provided by the USGS,GFZ,GCMT.The strike of fault plane Ⅱ is in good agreement with the eastern margin fault of Jishishan.
