| 摘 要： | 选取2008—2014年内蒙古测震台网速报的内蒙古自治区内地震事件,对每一事件采用单纯型、LocSAT、HypoSAT、HYP2000定位方法进行重新定位,以定位结果中的定位残差大小为唯一判定指标,考察4种定位方法的适用性,对比发现,单纯型方法定位残差最小,可作为内蒙古自治区地震速报的有效定位方法。

| Abstract: | The events were selected from 2008 to 2014 in Inner Mongolia, and each event was relocated using simplex, LocSAT, HypoSAT and HYP2000 method. The residual sizes of locating results can be used as a sole determinant index. In order to investigate the applicability of four methods, the results are compared based on locating earthquakes. With the minimum residual error, the simplex method is the most effective method for the fast determination of earthquake parameters in Inner Mongolia. |
