摘要
通过对1966年以来的华北地区地震活动期强震前的前性兆系列研究,得出华北地区在现今活动期内有统一的地壳应力场作用的结论。
The area of North China is one of the active earthquake areas in the east part of our country. In the area seismic activities are strong and the intervals between active periods are comparatively longer. The article relates the research work on the precursory earthquake series of strong quakes in the area within the present period since 1966 and comes to a conclusion that there is an unified crustal stress field acting in the present seismic period of the North China area.
