摘要
利用新疆喀什—乌恰地区记录的数字地震资料,用BLOC86程序初步定位,根据射线追踪原理,给出相对精细的P波速度模型。由此模型,用JHD联合震中定位方法对记到的小震进行精确定位,并对定位精度做初步分析。
Using the digital seismic data of Kashi-Wuqia area in Xinjiang, we used the BLOC86 program to locate preliminarily earthquakes. According to the ray tracing theory, we gave the relatively fine velocity model of P wave. Making use of the model, we used the joint hypocentral determination (JHD) method to locate refined small earthquakes. And we analyzed preliminarily the precision of the location.
