Geology and landslide potential using resistivity method in Paloh, Gua Musang, Kelantan

Research entitled geology of Kampung Paloh Tiga,the research was carried to fully understand the general geology of the research area.The main lithology at this area is Meta Mudstone,Andesite,Phyllite and Vitric Tuff. This geological mapping is conducted to update the geological map and study the general geology of study area. This part conductucted by interpreting the map such as land use map, stream map, terrain map and others. It helped the study of landslide at that area. This study also discusses the geomorphology, stratigraphy, structural geology, and historical geology of the study area. Kampung Paloh Tiga is located in Gua Musang district, which is positioned at the foot of Peninsular Malaysia's Main Range. The distribution of rocks found in the study area is igneous rock,sedimentary and metamorphic rock, according to research and data collection during mapping. To obtain a more accurate rock type, rock samples were collected and sent to a laboratory for petrographic analysis. The parameters that triggered the occurrence of landslide were identified.. In this research electrical resistivity method is used to analyses the subsurface and weathering grade that affect the landslide hazard. This geophysical method can review the structure and conditions under the surface. Besides, classified the grade of weathering which is a factor of landslide to occur. ArcGIS and Google Earth processed satellite-based geological mapping. . ArcMap's extension tool delineates landform units. Landform components were analyzed using geological maps. The research data were analyzed descriptively to characterize the subject area's geomorphology, landforms, and natural catastrophe risk. Next, electrical resistivity imaging is employed with parallel and perpendicular resistivity lines. The ABEM resistivity system measured subsurface earth's resistance. ABEM resistivity systems include Terameter LS, multifunctional cable, 40 jumper cables, 41 stainless-steel electrodes, a 12-volt battery, and a remote cable. Resistivity survey by Werner and Gradient. The result of apparent resistivity value that will be inversed using software to determine the true resistivity. Resistivity data then will be analyzed using Res2Dinv software.Results shows weak zones at each of the pseudosection that have the potential of landslide will occur which concluded that landslide is potentially happen in area that have swollen area that consist of water.
