Description

Some sediments (sandy soil and black soil layers) of head of the landslide block were investigated, which appeared by road construction. After landslide movement, sandy soil sediments filled on an irregular surface and black soil deposited continuously on a flat slope. These depositions increase the load and caused next landslide, which repeated several times. The IIIA slide block makes a synchronous development with advance toward an old stage of geographical cycle . A preventive policy of this landslide was planned on the base of interpretation of historic change of this landslide.
