摘要
本文对唐山7.8级地震各前兆学科共189个测项的震后变化进行了归类统计与分析,讨论了震后变化的5种类型数量上的差异特征与后续地震的关系,分析了震后异常的分布特征与后续地震区及其地震活动异常的对应关系,认为利用前兆学科的震后变化的某些综合特征配合测震学进行震后趋势判断有实用价值.
In this paper, the statisties and analysis of the variations of 189 observed items after the Tangshan M7. 8 earthquake have been made, the relation between the differential characteristics of 5 kinds of variations in quantity after the earthquake and the follow - up earthquakes has been discussed, the corresponding relation between the distribution characteristics of anomalies after the earthquake and the follow-up seismic area and anomalous seismic activity has been analyzed. It is considered that using some comprehensive characteristics of the precursors after earthquake, coordinating seismomitry method, to make tendency prediction is of practical value.
