摘要
利用CAP波形反演法、PTD方法、近震深度震相sPL测定、sPn与Pn震相走时法和远震深度震相法,对2020年1月19日新疆伽师M_(S)6.4地震震源深度进行精确测定。结果表明,5种方法测定的震源深度基本一致,该地震震源深度为17 km。伽师地震震源深度的准确测定可以为深入研究伽师震源区的发震构造和深部动力学环境提供参考依据。
Focal depth of Jiashi M_(S)6.4 earthquake in Xinjiang on January 19,2020 was accurately measured by using CAP waveform inversion method,PTD method,near earthquake depth phase sPL measurement,sPn and Pn phase travel time method and far earthquake depth phase method.The results show that the focal depth measured by these five methods is basically the same,and the focal depth is 17 km.The accurate focal depth determination can provide a reference basis for the in-depth study of the seismogenic structure and deep dynamic environment in Jiashi focal area.
