摘要
分析了河南安阳测震台用 DC— 型电磁辐射异常监测仪记录的地震电磁辐射异常曲线的特征 ,指出 ,用异常幅度和异常持续时间相结合的方法可突出地震前兆异常 ,用震例说明 ,电磁异常对中强地震的短临预报有一定的意义。
The characters of the electromagnetic radiation anomalous curves recorded by DC—Ⅱ electromagnetic radiation anomaly monitor of Anyang seismic station in Henan were analyzed,suggested that the method combined the anomaly amplitude with the anomaly duration can protrude the earthquake precursor anomalies,and showed by the examples of earthquake that the electromagnetic radiation anomalies are significative of the short term and impending earthquake prediction for the medium strong earthquake.
