Discussion on the range of epicentral distance of Pdiff phase at Menglian Seismic Station
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.
