在忻定盆地进行工作的基础上,认为本区活动断层以正断层为主。强震活动多集中发生在一定的活动构造带的某些地段,其往往是地质构造特殊部位。 根据活动构造的特殊部位并结合历史地震和现代地震的活动特征,在忻定盆地圈定出三个地震危险地段。即: 1、阳明堡——崞阳地震危险段; 2、忻州——石岭关地震危险段; 3、子干——播明地震危险段; On the basis of the work in Xinding basin, it is considered that the active faults in this area are mainly normal faults. The strong earthquakes mostly occur in certain areas of a certain active tectonic belt, which are often the special parts of the geological structure. According to the special parts of the active structure and combining the characteristics of the historical earthquakes and the activities of the modern earthquakes, three seismic risk lots are determined in the Xinding Basin. Namely: 1, Yangming Fort - Danang earthquake risk section; 2, Xinzhou - Shiling off the earthquake risk section; 3,
