【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300 km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300 km范围的5.0级以上地震有较好的对应关系.更多还原

【Abstract】 By analyzing the information of Gaoda well since 2002,analyzing the water level variation over the years and the abnormal morphology before the M≥5 earthquake around the observation well within the range of 300 km,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 M≥5 earthquake around the observation well within the range of 300 km.更多还原
