以模式识别方法提取南黄海地区中强地震前地震学综合异常信息

Abstraction of Seismological Synthetic Anomalies Information prior to Medium and Strong earthquake in Nanhuang Sea Region with Mode Recognition

以模式识别的 CORA— 3修改算法 ,使用历史有感地震和现代相应的地震资料 ,对南黄海地区中、强地震前地震学异常信息进行了尝试性提取 ,初步确定了其综合预报指标和规则。结果表明 ,该方法内符和外推检验效果较好 ,可试用于该区中。

Using historical sensible earthquake and modern earthquake information, the seismological synthetic anomalies information prior to medium and strong earthquake in Nanhuang Sea Regions is abstracted with modified CORA3 algorithm of mode recognition The prediction index and regulation are primarily determined The predicted result is credible, and may take it for medium term prediction of medium and strong earthquake
