Geology and landslide susceptibility analysis in Kampung Renok Baru, Gua Musang, Kelantan.

This research was covered with 25km2 area which aligned along latitude 4°55’15.0” N, 4°57’55.0” N, longitude of 102° 1’45.15” E, 102° 4’25.30” E. This study was carried out due to there is only big scale research and less information regarding geomorphological and stratigraphy aspects in study area. Also, landslide susceptibility analysis was conducted because of previous research not providing detail factors affecting landslide susceptibility and the map of hazardous areas. The purpose of this research is to produce geological map of study area in the scale of 1:25000, to generate landslide susceptibility map of study area with the scale of 1:25,000 and to determine factors triggered landslide and mitigation step in study area. This research involves study of geomorphology, lithological, stratigraphy, historical geology and structural geology. Furthermore, this study was carried out using remote sensing, online interpretation with helped of secondary data, producing map and then analysis each map integrated with Geographic Information System (GIS). This study area made up of two main formation which are Telong formation and Merapoh Limestone that consist of pyroclastic unit, metasedimentary unit and limestone unit respectively. The parameters that triggered to occurrence of landslide were identified such as slope, aspect, lithology, land use, drainage density and distance from road. The landslide susceptibility map was generated using Weighted Overlay Method (WOM) in ArcGIS. The landslide susceptibility map was produced and showed three zones classes of landslide vulnerability area which are low, moderate and high zones, where study area covered with low susceptibility of landslide so the probability of landslide to occur is low. Besides, the external factors triggered to landslide phenomena were determined which are rainfall intensity and anthropogenic activities. As a conclusion, all the research objectives were achieved and this research leading to greater awareness on the landslide occurrence of study area.
