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。
This paper has analysed and studied the variational characteristics of groundwat er level anomalies of Inner Mongolia precursory monitoring notwork within the ra nge of 300 km around the epicenter of the Zhangbei M S6.2 earthquake occurr ed on January 10,1998.The result showed that there were certainly anomalies of groundw ater level before and after the Zhangbei MS6.2 earthquake.By using the medium-sh ort term and impeading earthuquake prediction methods of hydrochemistry and grou nd-water level,the relationship between the Zhangbei M S6.2 earthquake and the gr ouped hydrochemical anomalies has been analysed and studied.the testable forecas te in midium-short term for the Zhangbei M S6.2 earthquake was made.The occ urrenc e time of the Zhangbei M S6.2 earthquake was in accordance with the judging resul t in this paper,and it is pointed out that the anomalies was a precursory reflec tion for the Zhangbei M S6.2 earthquake occurred on January 10,1998.
