A Preliminary Study on a Seismotectonic Model for the Active Faults in the Xining Urban Area
摘要
Abstract
On the basis of the Xining active urban fault survey, we studied the relationship between the active urban fault and fold deformation. The result of this research shows that the Hnangshuihe fault and the NW-striking fault on the northern bank of the Huangshuibe River are tensional faults on top of an anticline, the Nanchuanhe fault is a transverse tear fault resulting from differential folding on two sides of the fault, the east bank of the Beichuanhe River fault is a compressional fault developed on the core or climb of a syncline. By balance profile analysis of fold deformation and inversion of gravity anomaly data, we obtained the depth of the detachment plane and established the seismotectonic model of the Xining urban area. Based on the seismotectonic model, we analyzed the earthquake potential of the active urban fault.关键词
