Analytical Hierarchy Process Method for Mapping Landslide Susceptibility to an Area along the E-W Highway (Gerik-Jeli), Malaysia

In this study, the Analytical Hierarchy Process (AHP) method was used to produce a landslide susceptibility map for an area located in the central northern part of Peninsular Malaysia. The study was carried out using remote sensing data, field surveys, historical data and Geographic Information System (GIS) tool. Eleven factors that influence the occurrence of landslide were chosen for this study: Slope gradient, slope aspect, curvature, distance from road, drainage density, lithology, foliation dip, topographic/bedding relationship, lineament density, soil and rainfall. The Landslide Susceptibility Index (LSI) was computed from the combined weighed thematic maps of factors based on the assigned weights and ratings given by the AHP method. The AHP results were verified with existing landslide locations, which yielded the accuracy rate of 80.97%. Hence the landslide susceptibility map generated with the AHP method is useful for preventing or minimizing possible landslides and could be adopted in the proper planning for land use and construction in the future.
