Abstract: This research made a detailed assessment on influence scope and houses damage caused by Ⅵ, Ⅶ and Ⅷ intensity of the Datong-Yanggao earthquake (M_S6.1) in 1989 combined with statistical results about the extent of the village destruction of medium intensity earthquake disasters caused by M_S ≥ 4.5 earthquakes in the research area during 1949-2016 years. The assessment shows that brick-wood structure building has a certain anti-seismic performance, but it also exposed the defects that the overall vulnerability of rural housing lowered in the region and the vulnerability of rural resident population is still higher. The local government, the villagers should pay more attention to the construction of housing anti-seismic capacity, improve the overall anti-seismic performance of housing and enhance the awareness of earthquake fortification to reduce disaster losses.
