Gua Musang is one of the districts in the south of Kelantan. Over the years, land use and development grows rapidly in this karst topography which led to significant changes in landform and geomorphology. The changes worried to bring hazard to the enviromnent. Geohazard assessment can showed the level of hazard presents in the area. For this purpose, potential limestone geohazard map are prepared. The geohazard map was classified into zones and was the spatial prediction of potential limestone geohazard. The main objectives of the study is to produce an updated geological map of Gua Musang, Kelantan with the scale of 1:25,000. Not only that, the study also to analyse the potential surface and subsurface limestone features that may contribute to geohazard. Also to produce potential limestone geohazard assessment map of Gua Musang, Kelantan by using Geographical Information System(GIS). The landslide hazard evaluation factor(LHEF) rating scheme have been used to prepare the potential landslide geohazard zonation map of the study area. The preparation of the potential geohazard map involved summing the weighted values for six inherent causative factors for limestone instability which are lithology, rainfall, drainage density, land use, relative relief and slope morphometry. The results of the analysis were validated in the GuaMusang Town area from the field mapping in the study area. The resulting potential limestone geohazard map shows that in Gua Musang Town, the highest hazard zone present is moderate potential hazard which located in the Batu Neng area. Even so, there are area inGuaMusang Town shows hazard characteristic that could developed potential limestone geohazard in the future based on the field mapping. From the study, the results can be used for hazard prevention and land-use plarming.
