摘    要:本文对华北16次中强以上地震前多兆短临异常进行了分析,归纳出短临异常的综合变化特征。依据短临异常的综合特征,提出在中期异常背景上孕震过程由中期向短期过渡的两个定量化综合标志。研究了孕震后期在观测到较多数量短临异常情况下,能否发布5级以上地震预报意见的预报指标。作为本文结果的检验,计算了8次地震丧的综合标志和预报指标。本研究工作在短临预报中具有一定的实用价值。

关 键 词:短临异常 综合标志 预报指志 地震

Abstract:In this paper the features of comprehensive variation of the short-term and impending anomlies are induced based on analysis of various short-term and impending anomlies befor 16 moderate strong esrthquakes in North China. The authors proposed two quantitative comprehensive marks of seismogenic process transited from the medium-term to the short-term on basis of the comprehensive feature of the short-term and impending anomlies; at same time authors studied that if it can issue comprehensive prediction indices of M>5.0 earthquakes based on quite a few observed short -term and impending anomalies.Finally,the authors examined the comprehensive marks and indices before 8 earthquakes. The result has practical significance in the short-term and impending prediction.
Keywords:comprehensive mark  prediction index  seismogenic process
