该文指出了我国大陆某些地区之间强震的迁移规律,它有助于分析我国大陆地震活动高潮期是否开始,并可做某些地区的强震的趋势预报.1900年以来,我国大陆Ms≥7.0级地震的空间分布如图1.图中一区为喀什附近的地震密集区,二区为东北深震区,三区为海原达日、阿兰湖所包围的西北地区.这三个地区之间的强震具有一定的迁移规律.其中某些强震具有特殊的含义,由此来判别我国大陆地震活动高潮期是否开始.我们把这种预报方法简称为强震判别法.
This paper points out the regularity of strong earthquakes in some areas of our country and helps to analyze whether the upsurge of seismic activity in mainland China starts or not and to forecast the strong earthquakes in some areas. Since 1900, The spatial distribution of Ms≥7.0 earthquakes is shown in Fig. 1. The first zone is the seismic-intensive area near Kashi, the second zone is the deep earthquakes in northeastern China, the third zone is the northwestern area surrounded by Haidalangda and Alaranhu.These three Strong earthquakes between regions have certain migration rules, of which some strong earthquakes have special meanings, so as to judge whether the period of the high earthquakes in mainland China begins or not.
