摘要
以近 2 3年来湖北西部地区 ML≥ 4.0级地震前内符检验有一定震兆异常显示的 6项地震活动性参数作为指标 ,估计样本有震或无震类别 (1— 0 )的从属度 ,判定预报样本所属类别。根据模糊聚类分析方法对鄂西地区的地震进行综合预测研究 ,统计结果认为 :模糊聚类方法对鄂西地区 ML≥ 4.0级地震的预测具有一定的效能。
This paper estimates the subordinateness of the earthquake samples through the six items of active earthquake parameters,which are examined to have some efficient earthquake precursor anomaly from the earthquakes(M L≥4.0) occurring in the last 23 years in the west of Hubei province.Thus the samples are determined that they belong to seismic sort or nonseismic sort(1-0).According to the research on earthquake in the west part of Hubei by the method of fuzzy clustering analysis the statistical result proves that the method has certain efficiency for the prediction of middle earthquake in this area.
