1.前言笔者通过对大量地电资料的分析,发现深埋电极进行地电观测,能够排除表层干扰,突出地震异常。本文利用深埋电极的地电观测资料,总结了1983年菏泽5.9级地震前地电异常特征。2.菏泽5.9级地震前的地电异常菏泽5.9级地震前,震中周围300km范围内的地电异常反应是不同的(图1)。现分述 1. Preface The author through a large amount of geoelectric data analysis and found that the deep electrode for geoelectric observation, to exclude surface interference, highlighting the earthquake anomalies. In this paper, we use the geoelectric data of deep buried electrodes to summarize the geoelectric anomalies before the 1983 Heze M5.9 earthquake. 2. Geoelectric anomalies before the MS 5.9 Heze earthquake Before the MS 5.9 Heze earthquake, the anomalous geoelectric anomalies within 300 km around the epicenter were different (Figure 1). Now described
