摘要
通过对地震预测实践过程中成功和失败的震例总结 ,提炼出一套预报 6级以上强震的综合预测决策判据 :根据突变异常的数量和分布范围预测震级 ;根据突变异常的准同步涌现和某些外部触发因素预测发震时间 ;根据综合前兆异常相对集中区中地震活动性异常与前兆异常、宏观异常与微观异常配套出现来预测地震危险区。
Some successful and unsuccessful practices on the prediction of strong earthquakes( M s≥6) in south-western part of China are studied Based on these results of predictive practices, the comprehensive indexes for the predicting strong earthquakes( M s≥6) are summarized The indexes on the abnormal quantities and abnormal distribution position are able to determine the magnitude of a potential seismic event The quasi-synchronous emerge of abnormal items and some other triggering factors are able to determine the happening time of a potential seismic event If a lot of indexes of abnormal items appear focusing on a relative narrow area, this position may be the place of a potential seismic event
