The geological study of Kampung Belahat in Jeli, Kelantan, Malaysia, which is located close to the Thai border in northeastern Peninsular Malaysia, is the main subject of this research. The Jeli district, which spans an area of roughly 2,552 square kilometers, has three different geomorphological types: low, hills, and mountainous. Kampung Belahat is surrounded by a mix of flat, hilly, and mountainous terrain due to the area’s height range of 80m to 900m. The goal of the study is to update Kampung Belahat’s geological map, with a particular emphasis on geomorphology, lithology, and structural geology and to determine the landslide susceptibility of study area. Comprehensive geological data was gathered by laboratory work, sampling, and traversing during the geological mapping process. The area’s lithology consists of high-grade metamorphic rock types and intrusive igneous rock, with granite and gneiss being the main rock types. The granite rock shows signs of metamorphic processes, including 33% biotite, 46% quartz, 11% alkali feldspar, and 10% plagioclase. Gneiss rock, on the other hand, has flattened minerals as a result of metamorphism; it contains 13% alkali feldspar, 35% quartz, and 52% biotite. Granite was the primary geological structure observed, combined with visible quartz veins and joint and fault structures. The study took into account five factors: aspect, drainage density, lithology, slope, and land use. The Weightage Overlay Method (WOM) was used to process the data. The study area is categorized into three risk levels on the resulting landslide susceptibility map: low (5%), moderate (30%), and high (65%). This knowledge is essential for putting safety precautions in place, reducing potential harm during future development in the area, and reducing the likelihood of landslides.
