Geology and landslide susceptibility mapping using geographic information system (GIS) at Kampung Sungai Terah, Gua Musang, Kelantan

Kampung Sungai Terah, Gua Musang Kelantan, in Peninsular Malaysia's Central Belt, hosted the study. The research area's latitude and longitude are 4 '55' 4.97" N and 4 '52' 20.14". This research updates the 1:25,000 geological map of the study region. Landslide susceptibility is an estimate of where landslide will occur. This research's geological mapping included fieldwork, rock sampling, analysing geological structures, and studying geomorphological characteristics and drainage patterns. Field observation included geomorphology drawing and drainage pattern GIS software created the geological and thematic maps from the data. This region is 25% urban, 50% mountainous, and 25% plain, at an elevation of 100-200m. The studied region contains rectangular and dendritic drainage patterns from Galas River tributaries. Fluvial and denudational landform origins are studied. This Middle Permian-Middle Triassic silt is from the Gua Musang Formation. This region has igneous, metamorphic, and sedimentary rock. The research region has quartz-rich granitoid, limestone, slate, and phyllite. Geomorphology, stratigraphy, structural geology, and historical geology of the studied region are examined. There are few types of rock found at the study area which is granite, phyllite, slate and limestone. Weightage Overlay Method (WOM) in ArcGIS software created the landslide susceptibility map using the landslide's characteristics. The susceptibility map revealed low, moderate, and high zones within 25km2 area. The research area's mountainous terrain made slope the biggest landslide threat. In conclusion, detecting landslide susceptibility improves research area knowledge of landslide processes and helps identify the most probable failure locations in landslide-prone areas.
