摘要
通过学习前兆综合信息提取软件的使用方法及其在华北地区中的应用,收集并整理黑龙江地区定点前兆观测资料共计14项,逐一计算并提取地震前兆信息量,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M 4.0以上地震预测效能,给出黑龙江地区地震短期综合预测指标和方法。
Through learning the using method of precursor comprehensive information extraction software, and its application in North China, the fixed point observed precursor data of 14 items in Heilongiiang region are collected and sorted. Their earthquake precursor information is calculated and extracted one by one. Based on this, the comprehensive temporal curve of earthquake precursor information of this region is calculated. The prediction efficiency for earthquake with M≥.0 is analyzed and calculated. The earthquake short-term integrated prediction indexes and methods are given.
