Abstract

     Among natural hazards, landslides happen frequently and severely impact local people and environment in slope areas. The research objective was to determine landslide susceptibility triggered by the various factors in the high slope area. Analytic Hierarchy Process (AHP) and GIS methods were used to predict the landslide susceptibility in the whole Mai Chau district. Three categories of landslide susceptibility were defined as low, moderate and high susceptibility. The area of high susceptibility was evaluated as a significant help for land users and decision makers in the research district to correct unsuitable land use types. The results will be verified by an investigation of actual landslide happened in the previous period of time to specify the accuracy of the prediction.
