| 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 earthquake swarms from 1970 up to now in the North China region. It is shown that the migration and the stage by stage activity of earthquake swarms are obvious before Tangshan earthquake. The characteristics are preliminarily analyzed by using the theory of three dimensional rheological inclusion earthquake generating model. Predicted test of Zhangbei earthquake show that the migration and earthquake swarms should be applied to the medium tem prediction of strong earthquakes. |
