【摘要】 采用震源深度测定的确定性方法（PTD）和震源机制CAP反演法，对2019年11月30日河南淅川丹江口水库发生的M_L 4.2地震进行分析，重新计算了此次地震的震源深度。结果表明，2种方法所得到的震源深度基本一致，均约为7.0 km，与中国地震台网中心统一编目结果（7.1 km）相差不大，此结果可能表明地震监测台网相对较好的情况下，用不同方法测得的震源深度相差不大。更多还原

【Abstract】 In this study,we used the PTD method,the CAP method to analyze the M_L 4.2 earthquake occurring on November 30,2019 around the Danjiangkou reservoir,Xichuan,Nanyang.The focal depth of the earthquake was calculated and the result of the two methods were in accordance with the depth of 7.0 km,which is no different than the depth (7.1 km) of the unified cataloging results of the CENC.The results indicate that when the earthquake monitoring network is relatively good,the depths measured by different methods are not much different.更多还原
