| 摘 要： | 分析了东郭井自2008年1月观测以来出现的水位与水温成组异常及其与周围中等地震活动的关系,研究结果显示:异常与地震有较好的对应关系,其异常的基本特征是水位阶降与水温缓升的形态配套,异常的幅度与震级大小有一定关系,异常持续的时间与井震距有一定的关系,还讨论了异常的机理。

| Abstract: | The relationship between groundwater level and groundwater temperature bunching anomalies of Dongguo well and moderate earthquakes activity in surrounding area are analyzed in this paper. The result indicates that the essential characteristic of the anomalies is the synchrony of the step drawdown of the groundwater and the slow rising of the groundwater temperature, and there is corresponding relation be- tween the anomalies and the earthquakes. The amplitude of the anomalies is related to the magnitude of the earthquakes; the lasting time of the anomalies is related to distance between the well and the epicenter. In addition, the mechanism of the anomalies is discussed. |
