Abstract: This paper is based on the field investigation of the geological d isaster that caused by the 5. 12 W enchuan Earthquake in Q ingyang City and P ingliang City, Gansu Province. It is found that the earthquake-induced collapses and landslides are charcterized by sm all type and large number and arem ainly distributed at the of the edges ofmodern erosion ditch; The earthquake-induced landslides distributed in the tab leland surface, gentle slope hills and tableland of the valley, is consistentw ith the cave dw elling and the engineering construction. A lthough this earthquake has not caused large or
