本文讨论了板块边界地震,华北中强以上地震及其与邢台应力“窗口”效应的关系,认为,三者均反映了大范围区域动力的变化。这对地震预报是有一定意义的。 This paper discusses the relationship between plate boundary earthquake, moderate strong earthquakes in North China and its “window” effect with Xingtai stress. It is considered that all three reflect the dynamic changes in a large area. This is of some significance for earthquake prediction.
