Geology and landslide susceptibility assessment in South Of Aring 6, Gua Musang, Kelantan

The research is entitled “Geology and Landslide Susceptibility Assessment in South of Aring 6, Gua Musang, Kelantan”. This study is focused on the landslide hazard assessment using Geographic Information System (GIS) application. The study area is bounded between coordinates 4º 53’0” N to 4º53’30” N of latitude to 102º 21’30” E to 102º 24’30” E of longitude. The objectives of this research are to produce a geological map of the study area in the scale of 1: 25000 which is covered 25 km2 of the study area. The factor that triggered landslide susceptibility of the study area is analysed through this research. This research also involved the study of geomorphology, lithostratigraphy, structural geology and historical geology. All the data of these study are obtained from secondary data such as research on previous research, satellite imagery, Google Earth, and aerial photograph. In order to produce landslide susceptibility map, the method of Weighted Linear Combination (WLC) is used in this research. Eight parameters are chosen as landslide causative factors and the landslide susceptibility zonation map is generated from GIS application. The rainfall intensity is a factor that triggered the occurrence of landslide in the study area. From the analysis and interpretation of landslide, there is three classes of landslide zonation such as low, medium and high zones. The slope is the most influence hazard because of the hilly area in the study area. The increase value of the lineament density and drainage density also influenced the landslide occurrences in the study area.
