根据１９００年以来的地震活动资料，从整体活动的观点出发，对３０多ａ的地震活动演变特点研究后，认为１９６６年到１９７６年华北地区发生的４次Ｍｓ≥７．０地震是一组时间相随有序、空间成带有节而且相互关连的一个大系统的整体链式大活动。并由此而提出了对今后地震活动的粗浅看法，认为由邢台、渤海、海城、唐山４大地震围限的主活动区在今后一个相当长的时期内难于重复同级大地震，而且受影响所及的山西地震带、华北块体北缘的阴山—燕山等地的一些“衍射活动”也将随大区的演变逐渐成为华北的常态活动，今后Ｍｓ６．０左右的地震活动将被视为本区的高峰活动 According to the seismic activity data since 1900, from the viewpoint of the whole activity, after studying the evolution characteristics of more than 30 years of seismic activity, it is considered that the four Ms≥7.0 earthquakes occurred in North China from 1966 to 1976 are a set of time In a systematic and orderly manner, the space becomes a large, systematic, chain-like activity with connections and connections. From this, we put forward a superficial view on the future seismic activity. It is considered that it is difficult for the main active area surrounded by the four large earthquakes in Xingtai, Bohai, Haicheng and Tangshan to repeat the same-magnitude earthquakes in a long period in the future. Some “diffraction activities” in the Shanxi Seismic Belt affected by this project and the Yinshan-Yanshan Block in the northern margin of the North China Block will also gradually become normal activities in North China with the evolution of the major areas. In the future, the seismic activity around Ms6.0 will be regarded as For the region’s peak activities
