由显著地震的动态图象寻找华北强震活动场所

STRONG SEISMIC ACTIVITY REGIONS IN NORTH CHINA FOUND BY DYNAMIC PATTERNS OF NOTABLE EARTHQUAKES

  • 摘要: 本文根据华北强震前,特别是1966年以来华北一些给定的强震前,沿时间先后顺序,由大到小、由近及远地回溯所得不同时段诸显著地震的空间分布图象的重心,与应用"黄金分割"所得的最优破裂点,两者结合以求得"动态应力椭圆"的办法来探讨了华北强震的活动场所。通过一些实例看来,有可能把这种办法应用到趋势预报中去,为未来强震的活动场所作出长期、中期或短期的半经验、半定量的估计提出有用的依据。本文认为形成这种图象的成因主要是地震条带在地震的整体活动时期能量释放具有一定规律的"动态平衡"的结果。

     

    Abstract: In this paper, the strong seismic activity regions during earthquake preparation and immediately before earthquake are studied by "dynamic stress ellipse" method which is derived from both the centres of gravity of spatial distribution patterns of notable earthquakes in defferent time stages before strong earthquakes in North China and optimum fracture points which are obtained by "golden section" method.Through some examples, it is considered that the "dynamic stress ellipse" method can be applied to tendency predict ion and it can provide a useful basis for semi experience and semi-quantitative long-term, mid-term and short-term estimation of future strong seismic activity regions.It is considered that the formation of such patterns is mainly the result of "lynam ic energy balance" of seismic block or seismic belt.
