摘要
对1998年1月10日河北张北6.2级地震前后,内蒙古井网的兴和、三号地、丰镇、凉城井地下水位观测值的变化与地震的关系进行了分析,认为这次地震前的地下水位异常具幅度大(达3.5m左右)、持续时间长(达2.5a)、先震中后外围逐渐出现等特征
An analysis for the relationship between the groundwater level change of the well network of Inner Mongolia (Xinghe well,Sanhaodi well,Fengzhen well,Liangcheng well)and the earthquake before Ms6 2 Zhangbei earthquake on January 10 ,1998 was made.The analysis suggested that there are features of the large amplitude of groundwater level anomaly,the long duration and occurrence in the epicenter before the earthquake.
