摘要:
2014 年2 月12 日新疆维吾尔自治区于田县发生MS7. 3 地震,随后又发生了一系列余震。本文采用测定震源深度的确定性方法计算了于田MS7. 3 地震序列的深度,震相数据来自于中国地震台网中心编目数据库,并结合使用了新疆数字地震台网记录的地震波形原始资料。

Abstract:
An MS7. 3 earthquake happened on February 12,2014 in Yutian county,Xinjiang Uygur Autonomous Region,which was followed by a series of aftershocks. It is very important work to determine the depth of seismic sequence timely. Accurate determination of the focal depths of the foreshock,main shock and aftershock sequence can provide more information about fault structure,source process,crust and mantle structure,the motion of the plates and a series of problems. The paper uses a deterministic method for determination of earthquake depth to measure the depths of Yutian MS7. 3 seismic sequence in Xinjiang. The original phases data are adopted from the catalog database of China Earthquake Networks Center,combined with seismic wave records from the Digital Seismic Network Center,Earthquake Administration of Xinjiang Uygur Autonomous Region.
Key words:  Focal depth  Crustal velocity mode  l Seismic sequence  PTD method
