Water level anomalies and seismic analysis of Tonghai Gaoda

摘要: 通过分析高大井2002年以来的资料,对多年来水位变化特征与观测井300km范围内发生的5.0级以上地震前的异常形态进行分析发现,高大井水位在震前表现出趋势和短临变化特征,水位动态异常与观测点周围300km范围的5.0级以上地震有较好的对应关系.Abstract: By analyzing the information of Gaoda well since2002,analyzing the water level variation over the years and the abnormal morphology before the M5 earthquake around the observation well within the range of 300km,we found that Gaoda water level shows trend and short term variation characteristics before the earthquake,and it has a good corresponding relationship between the dynamic anomaly in water level and the M5 earthquake around the observation well within the range of 300 km.
