| 摘 要： | 使用新疆地震台网地震观测资料，采用 MSDP 系统单纯型、Locsat、Hypo2000、hypoSAT 等4种定位软件和经典直观的中线法、石川法、交切法作图法及 BLOC86速度模型计算定位方法，对2010年1月18日19时35分呼图壁 ML 4．0地震分别定位。将各自确定的震源深度、震中参数进行对比分析，认为单纯型定位方法确定的震源深度太浅。

| Abstract: | Based on the seismologic observation data of Xinjiang Seismic Network,the ML 4.0 earthquake which was occurred in Hutubi at 19∶35 on January 18,2010,is located by using the locating software such as simplex algorithm location method of MSDP system,Locsat,Hypo2000,and HypoSAT.On the other hand,some classical location algorithm such as the midline method,Ishikawa Nori,intersection method,mapping method,and BLOC86 velocity model computing positioning method are also used at the same time.Through comparative analyze and discuss the focal depth and the parameters determined by the two ways,it can be concluded that the focal depth which is determined by using the simplex algorithm is too shallow. |
