四种地震定位方法的定位效果浅析

摘要

选取2008年以来内蒙古自治区、内蒙古测震台网速报范围内的所有地震事件，分别采用单纯型、LocSAT 、Hyposat、HYP2000地震定位方法进行重新定位。以定位结果中的发震时刻、震中位置、震源深度、震级残差为主要分析对比指标，与国家台网中心发布的正式速报结果进行对比，发现单纯型定位方法为区内速报地震的优选方法。%All the earthquakes in the range of Inner Mongolia Autonomous Region and rapid reported within Inner Mongolia seismic network since 2008 are selected for relocating by the simple ,LocSAT ,Hyposat ,HYP2000 method .The origin time ,epicenter loca‐tion ,focal depth and magnitude residual in the locating results are as the main indexes to compare with the formal reporting results issued by National Networks Center .The results show that the simple locating method is the optimization method for earthquake rapid report in the region .
