摘　　要：2012年8月30日张家口M_L3.7地震前,怀来4井水汞出现明显高值变化,分析发现,该变化为张家口M_L3.7地震震兆信息,是一起典型的短临异常变化。Before August 30,2012 Zhangjiakou ML 3.7 earthquake,significant short-impending anomaly of water mercury appears at Huailai-4 well.In this paper,the whole process of the observation and analysis of the anomaly is described.The mechanism is briefly discussed,for improving earthquake prediction of this area.
