地震迁移始发区的前兆在地震预测中的意义

摘要

地震迁移可广义化为构造事件的迁移。快速构造事件为地震，次快速事件可形成前兆。假使在昔日震中迁移始发地区出现了前兆，则可作两个方案的预测：一个是在前兆出现地区附近可能发生地震；一个是在昔日地震迁移所至地区可能发生地震。后者是本文讨论的重点。文中列举了五个实例。%Earthquake migration may be generealized as a tectonic event migration.Quick tectonic event is earthquake,and the secondary quick tectonic event may form precusors.If some precusors appear in the starting region of the past earthquake migration,two predictions may be made:one is that an earthquake may be possible to occur around the place appearing preeusor,and the other,which is also the focus of this paper,is that an earth-quake may be possible to occur in the stopping region of the past earthquake migration.Five examples are presen-ted in the paper.
