Abstract: The study was conducted to determine the weight of factors influencing landslides through the algorithm Analytical Hierarchy Process (AHP). These factors were used as inputs for establishing a landslide susceptibility map based on the geographic information technologies (GIS) at A Luoi District, Thua Thien Hue province. Results of the study showed that landslide risk could be divided into five levels: very low risk of landslide covered 17,638.22 ha (14%), low risk areas accounted for 41,036.20 ha (34%), medium risk of landslide covered an area of 22,380.84 ha (18%), high risk area was 27,176.99 ha (22.19%), and very high risk area was about 14,231 ha (12%). The results of this study could be used to support the implementation of land use planning, which could help reduce adverse impact of landslides on people and property.Â
