摘要
地震活动图像的Ａ（最大前震）、Ｂ（第二大前震）两点的连线与主震位置有明显的关系，用此判断未来主震的震中范围，其效果颇好，再加其它资料的配合，使判断精度提高。此方法的资料自检符合率，陆地达９２％。震例检验的效果也较好。
There is significant relation between main shock locatiion and the linked line be-tween maximum foreshock location(point A)and secondry(point B).The judging ac-curacy will be raised with the additional other data. The rate of data check for themethod is 92%in mainlaud China,actual earthquake check is also satisfactory.
