摘要
采用 2014 年 3 月至 2022 年 12 月孟连地震台测震资料,对震中距为 90°—175°的远震进行分析.分析结果表明,Pdiff震相在孟连地震台出现的震中距范围为92°—172°,计算得到的Pdiff震相走时函数与理论值基本吻合,表明其一致性较好.
Abstract
Based on the seismic data of Menglian Seismic Station from March 2014 to December 2022,the teleseismic events with epicentral distance from 90° to 175° are analyzed.The results show that the epicentral distance range of Pdiff phase at Menglian Seismic Station is from 92° to 172°,and the travel time function of Pdiff phase is basically consistent with the theoretical value.
