摘要: 通过对华北地区1970年以来震群活动的分析表明,唐山地震前的震群活动显示出一定的迁移性和阶段性。应用流变介质包体孕震模型的理论进行了初步力学分析。张北地震的预测检验表明,震群活动的迁移性与阶段性对强震的中期预测具有一定指导意义。

Abstract: In this paper, we studied the earthquakes warms from 1970 up to now in the No rth China region. It is shown that the migration and the stage-by-stage activ ity of earthquake swarms are obvio us befo re Tang shanea rthquake. The characteri sticsare preliminary lyanalyzed by using the theory of th ree-dimensional rheological inclusion earthquake generating model. Predicted test of Zhangbei ear thquake show that the migration and earthquake swarms should be applied to the medium-tem prediction of strong earthquakes.

Key words: Earthquake swarm, Stage-by-stage characteristics, Tangshan earthquake, Zhangbei earthquake
