Landslides susceptibility mapping using the Geographic Information System (GIS) approach in Temangan, Machang Kelantan

Abstract

The purpose of this study is to generate a landslide susceptibility map using Analytical Hierarchy Process (AHP) method using GIS approach at Temangan, Machang District in Kelantan. This research site was encompassed a 25-squarekilometer region. Landslide occurrence was influenced by seven (7) parameters, including lithology, aspect, landuse, slope, distance to road, distance to fault, and distance to stream. The AHP approach was used to determine the weights of parameters and their classes. The landslide susceptibility map classified three (3) susceptibility grades (low, moderate, and high). The higher the class value, the greater the landslide susceptibility, whereas a lower number indicates a reduced landslide susceptibility. Based on the findings of the landslide susceptibility map, it is reasonable to conclude that the studied region has a low susceptibility percentage and a low likelihood of landslide occurrence.
