基于“十五”测震分析处理软件MSDP的多种地震定位方法

摘要

3 268 ML≥l. 0 earthquake events recorded by the Shanxi Seismic Network from 2001 to 2008 are selected for this study. Based on the "the tenth-five year plan" seismological analysis program MSDP, the comparative study on various location results which are obtained by the simplex, HYPO2000, LOCSAT, HYPOSAT methods is carried out. This study indicates that the location result by the simplix method is more stable and it should be the most ideal location method for events wherever they are in the network, at the boundary or out of the network.%选取山西地震台网2001-2008年M1≥1.0的3 268个地震事件数据,用“十五“测震分析处理软件MSDP的单纯型定位法、HYPO2000、LOCSAT、HYPO)SAT定位方法的定位结果进行对比,分析认为:单纯型定位法的定位结果相对稳定,是网内、网缘和网外最理想的定位方法.
