摘要: 使用距1998年1月10日张北MS6.2地震300km范围内的内蒙古自治区前兆台网5口水井的地下水位资料,分析了地下水位趋势异常特征及张北MS6.2地震前后10天地下水位的微动态特征,表明在张北MS6.2地震前后地下水位确实存在着明显的异常反应。并用"八五"攻关水化、水位地震短临预报新方法分析研究了张北MS6.2地震前后水位群体异常的变化特征与张北地震的关系,对张北MS6.2地震做出了中期、短期、短临尺度的检验性预测,张北MS6.2地震的发震时间和本文的判断结果基本符合。指出内蒙古自治区前兆台网地下水位异常是1998年1月10日张北MS6.2地震的前兆反映。Abstract: This paper has analysed and studied the variational characteristics of groundwater level anomalies of Inner Mongolia precursory monitoring notwork within the range of 300 km around the epicenter of the Zhangbei MS6.2 earthquake occurred on January 10,1998.The result showed that there were certainly anomalies of groundwater level before and after the Zhangbei MS6.2 earthquake.By using the medium-short term and impeading earthuquake prediction methods of hydrochemistry and grou nd-water level,the relationship between the Zhangbei MS6.2 earthquake and the grouped hydrochemical anomalies has been analysed and studied.the testable forecaste in midium-short term for the Zhangbei MS6.2 earthquake was made.The occurrence time of the Zhangbei MS6.2 earthquake was in accordance with the judging result in this paper,and it is pointed out that the anomalies was a precursory reflection for the Zhangbei MS6.2 earthquake occurred on January 10,1998.
