摘要
识别地下水动态地震前兆异常,必须根据观测井地质及水文地质条件,分析地下水的多年动态特征,影响水位的干扰因素及异常变化与地震活动的关系。本文通过上述分析,认为大同6.1级地震前,河北省地下水网中万全、雄县、完县三口井存在水位异常变化。
In recognizing seismic precursory anomaly of groundwater regime, we must analyze the characteristics of groundwater regime in many years, disturbering factors on water level and the relationship between the anomalous variation and seismic activity based on geological and hydrogeological condition of observational wells. In this papar, throuth above analysis, it is considered that there were anamalous variations in water lever in three wells at Wanquan, Xongxian and Wanxian of the groundwater observational network of Hebei provnce prior to the Datong 6.1 earthquake.
