摘    要:在单项地震前兆异常判据和预报指标分析的基础上 ,构建了单项异常指数计算公式 ,进而定义了综合异常指数 ,用于提取多种地震前兆异常的综合群体特征。作为算例计算了新疆北天山乌苏地区 8种地震学参数的综合异常指数 ,结果表明两组地震前综合异常指数均出现了明显的高值异常变化过程。

关 键 词:地震预报  前兆异常  综合异常指数

Abstract:In order to describe the comprehensive group characteristics of many kinds of earthquake precursor anomalies, a comprehensive anomaly index is defined through constructing a formula calculating single anomaly index on the basis of the analysis of single earthquake precursor anomaly criteria and prediction index. And it was applied to the computation of the comprehensive anomaly index of eight kinds of seismological parameters in the Wusu area in North Tianshan, Xinjiang. The result indicates that the comprehensive anomaly index showed obvious varying process of high-value anomaly before two groups of earthquakes.
Keywords:Earthquake prediction  Precursor anomaly  Comprehensive anomaly index
