华东地区地震综合前兆信息量及其映震能力分析

ANALYSIS OF EARTHQUAKE SYNTHETIC INFORMATION AND ITS EARTHQUAKE REFLECTING ABILITY IN EAST CHINA AREA

摘要: 收集并整理华东地区定点前兆观测资料共计72项,逐一计算并提取它们各自的地震前兆信息量,在此基础上,合成计算得到该地区地震综合前兆信息量时序曲线,分析并计算5.0级以上地震预测效能,给出华东地区地震短期综合预测指标和方法。

Abstract: In this study, 72 fixed precursor observation items in eastern China area are collected and processed.To each observation item, the earthquake information are calculated separately and combined into one earthquake synthetic information time series.By analyzing the predication efficacy of the time series to Ms≥5.0 earthquakes, this paper gives the short-term synthesis predication index and method to Ms≥5.0 earthquakes in eastern China.
