摘要
根据中国、塔吉克双方地震资料，研究帕米尔地区深震震相特征及震源定位。结果表明：区内深震震相有明显的区域特征，由新疆境内的数台资料，可以识别深震震相；用直达波来模拟深震源地震Ｐ、Ｓ波的传播是可行的，试算震例说明，在一定的震中距范围内（△＜８°），精度完全符合使用要求；帕米尔地区速度模型，经过反复分析测算，及几十次震例计算验证，可以推广使用。
Based on the seismic data from Tajikistan and China,the characteristics of deep seismic phase and hypocentral localization in Pamir region are analyzed. It is indicated that the deep seismic phase has remarkable regional features, which can be identified by the data fromseveral stations in Xinjiang. It's available to simulate the P,S waves of deep focus earth quakes by direct body wave. After estimation,it is got to know that in a certain epicentral distance (△<8°), it fitted actual requirement in precision. Therefore,the velocity model for Pamir region is of wide usage through much estimation and more times of cases verification.
