摘　　要：震源深度是地震定位的一个重要参数,通过利用sPn震相的特点分析2010年4月14日青海玉树7.1级地震及其余震,进而计算出该地震的震源深度。这种分析和测定方法简捷准确,能够得到较为精确的地震震源深度。The focal depth is an important parameter of earthquake location. Yushu Ms7.1 earthquake on April 14^th,2010 and its aftershocks are analyzed by taking advantage of sPn characteristics of seismic phase, and then calculated the depth of the earthquake. The analysis determination method is simple and accurate, and it can get more accurate earthquake focal depth.
