【摘要】 本文采用地震地质,地震活动性,区域应力场相结合的综合分析方法,来寻求近期地震危险区的静态标志。又以中小地震活动图象,局部应力场方向及初动符号矛盾比的变化,强地震的重复性等作为确定潜在源区的动态因素。根据地震活动强弱交替的客观规律,探讨了今后地震活动的总趋势。最后提出对河北省及其邻近地区5—10年危险区的看法。更多还原

【Abstract】 By adopting an analysis methodology of integrating the data of seismogeology, seismicity and regional stress field, the static indicators of earthquake-prone areas in the near future are explored in this paper. Further more, based upon the information of local stress field and the changes of contradictory ratio of first motion as well as recurrence of strong quakes, the dynamic factors of source areas are determined. And according to the laws governing the alternation of strong and moderate seismicities, a general trend of earthquake activities in future is studied. Finally, the seismic risk for Hebei Province and its adjacent areas in the coming 5-10 years is estimated.更多还原
