通过分析庐江汤池1号井水氡观测资料影响因素、异常变化特征及异常对应的典型震例,研究水氡异常与地震活动的关系。分析认为,该井点映震效果较好,观测以来有近震前兆异常,特别是远大震震后效应明显,水氡映震具有一定的方向性,特别是对井点东南部地区有一定映震能力。 By analyzing the influencing factors, abnormal variation characteristics and typical earthquake cases corresponding to the observed data of water radon in Tangchi No. 1 well, the relationship between water radon anomalies and seismic activity is studied. The analysis shows that the well point has better anti-earthquakes and near-anomalous precursory anomalies since the observation, especially after the epicenter. The radon-bearing earthquake has a certain direction, especially for the southeastern part of the well Shock ability.
