摘要
本文改进了时纬线差的分析方法,改善了残差异常与强震的相关关系,减少了虚报率。综合分析两种方法的异常,可对预测地震的远近大小提供更多信息。给出了1983年以来的时纬线差异常与全部5级以上地震的对应结果。最后讨论了可能的物理机制。
This paper could bring about an improvement of the analytic method for time-latitude residual. The correlation of residual anomalies with strong earthquakes has been made better, whth the result that false alarm rate has been reduced. When anomalies of two methods have been synthetically studied, it can provide a lot more informations about distance and magnitude for earthquake predication. Results of time-latitude residual anomalies corresponding to all shocks of more than 5 magnitude, since 1983 have been given too. Finally, possible physical mechanism has been discussed.
