Besides, the social and economic activities, especially in the construction of transportation projects also contribute significantly increased landslide phenomena. The main purpose of research aimed at partitioning the risk of landslides in Hoa Vang district, Da Nang city. The research results show that areas with high risk of landslides occupy in large area. In general, the slope of the terrain where the thickness of the weathering layer and slopes dominate cause of the process can easily occur landslides.
