呼和浩特区内活动断层的超低频电磁波探测研究
|
摘要
呼和浩特地区发育多条活动断层,属地震高烈度带。对研究区内的活动断层采用超低频电磁探测方法,通过对探测数据进行高精度处理、图像精细解译,初步厘定呼和浩特市新华广场断裂、小黑河断裂和大黑河断裂3条主要活动断层的位置、断距、性质、活动性,为呼和浩特市城市规划、防震减灾等工作提供重要依据。大黑河断裂最大断距与最小断距相差为110m,小黑河断裂最大断距与最小断距相差为60m,新华广场断裂最大断距与最小断距相差为64m,判定大黑河断裂在新近纪末的活动性最大。
Hohhot region is the high intensity earthquake zone due to the growth of a number of active faults.The ultra-low frequency electromagnetic detection method is used to study active faults in the region,through high-precision processing of detecting data and precise image interpretation.By using the above technology,the location,the displacement,the nature and the activity of the main three faults are clarified to serve for the urban planning,earthquake disaster prevention and mitigation in Hohhot.The difference between the maximum and minimum displacement of Dahei River fault is 110 m,which are 60 m of Xiaohei River fault and 64 m of Xinhua Square fault.These data show that the Dahei River fault is the most active fault at the end of Neogene period.
