高邮地震台地电阻率异常特征与地震关系研究

应用归一化月速率法研究了高邮地电台周围200km范围内发生的固镇5．0级、溧阳6．0级、射阳5．1级、常熟5．1级和台湾地区6．4～7．6级4次地震的地电阻率变化。结果显示，对于邻区的4次近震均在出现负异常后发生，而台湾远区地震均发生在正异常之后，笔者研究认为，高邮台地电阻率归一化月速率异常可能与该台特殊的地理位置和台址有关，该台地电阻率对200km范围内和特殊位置(台湾地区)中强以上地震具有较强的映震能力。

Study on the relation of ground resistivity anomalies in Gaoyou Seismostation with earthquakes

The variation of ground resistivity in Gaoyou Seismostation before Guzheng M5.0, Leiyang M6.0, Sheyang M5.1, Changshou M5.1 earthquake, which occurred within 200km around Gaoyou, and four earthquakes from M6.4 to M7.6 occurred in Taiwan area, is studied with normalized monthly rate method. The results show that the earthquakes in the neighboring region occurred behind the negative anomalies, while the earthquakes in Taiwan area occurred behind positive anomalies. It is concluded that the ground resistivity anomalies in Gaoyou seismostation may be relevant to its special location, and these anomalies ha,ve some capacity to reflect the moderate and strong earthquakes occurred within 200km range and some special positions (such as Taiwan area).
