Landslide Susceptibility Mapping Using the Geographic Information System (GIS) Approach

Abstract

The purpose of this study is to generate a landslide susceptibility map using GIS approach (Analytical Hierarchy Process (AHP) method) at Temangan, Machang District in Kelantan. This study area was located at Temangan, Machang that covers an area of 25 km2. Seven (7) parameters that triggered the occurrence of landslide were determined such as lithology, aspect, landuse, slope, distance to road, distance to fault and distance to stream. The result of landslide susceptibility map shows three (3) susceptibility classes, low, moderate, and high). The higher the class value, the higher the landslide susceptibility whereas lower value means a lower susceptibility of landslide. Based on the result of Landslide Susceptibility Map, it can conclude that the study area consist of low susceptibility percentage and the probability to landslide occurrence is low
