摘要
本文利用电磁波观测台的实测资料,对宁蒗Ms5.1级、会泽Ms4.4级地震前电磁波异常信号特征、干扰排除、异常判别进行研究,分析了震前电磁波信号图象和异常时空特征,得出电磁波主信号异常出现在主震前20天左右的结论。
This paper presents study on the anomalous characteristics,disturbance exclu- sion and anomalous discrimination of the electromagnetic emission signals prior to Ninglang earthquake(Ms=5.1)and Huize earthquake(Ms=4.4)using the data of the electromagnetic observational sites,and analyzes the temporal-spatial charac- teristics of patterns and anomalies of electromagnetic signals prior to the earthquakes.It is concluded that the anomalies of main electromagnetic signals ap- pear some 20 days before main earthquakes.
