地震空间分布因子Zk及其在唐山地区的应用

根据空间距离方法,给出了地震空间分布因子Z_1的统计计算方法,并指出地震空间分布因子Z_1可以较好地判断地震空间分布类型。利用唐山地区的地震资料,对地震空间分布因子Z_1在地震预报中的实际应用进行了探讨,指出Z_1对中强地震具有一定的震兆反应能力。本文还就不同的序列处理方式及不同的震级下限对地震空间分布因子Z_1的影响,进行了深入的探讨。

STUDY ON SPATIAL FACTOR Z_k AND ITS APPLICATION TO TANGSHAN AREA

According to the spatial distance method of spatial points distribution, the calculating method of the spatial factor Zk was used in this paper to judge the type of the earthquake distribution. The Zk values can also be put into practice of earthquake prediction in Tangshan area. It shows that Zk values become higher and can last for several months before a moderate shock. Finally, the different handling methods on earthquake sequences and different low limits of magnitudes, as well as their influences on Zk values, have been discussed.
