【摘要】 武汉市岱山中学地电场观测站在以随州ML4.1地震和内乡ML4.7地震为代表的两次有感地震活动前,于2000年1月和4月测到两次地电场异常。地电场异常超前时间约17天。4月中旬的地电场异常场强、量级较大,与武昌地震台测到的内乡ML4.7地震的特殊的大量级地动位移具有一定的相关性。更多还原

【Abstract】 In January and April of 2000,two geoelectric anomalies were observed by Daishan middle school observation station in Wuhan before two moderate earthquakes——Suizhou earthquake(ML4.1) and Neixiang earthquake(ML4.7).The geoecletric field anomaly happened prior to 17 days of the earthquakes.The magnitude of the anomaly for Neixiang earthquake is comparatively bigger than the Suizhu earthquake,it may be related to the former inducing bigger ground displacement at Wuhan seismic station.更多还原
