Abstract. As a result of dearth of relevant information about Landslides Susceptibility in Nigeria, the monitoring and assessment appears intractable. Hence, the study developed a Remote Sensing approach to mapping landslides susceptibility, landuse and landcover analysis in Jos South LGA, Plateau State, Nigeria. Field Observation, SPOT 5 2009 and 2012, ASTER DEM 2009, Geological Map 2006, Topographical Map 1966 were used to map Landslide Susceptibility and Landuse /Lancover Analysis in the study area. Geospatial Analytical Operations employed using ArcGIS 10.3 and Erdas Imagine 2014 include Spatial Modeling, Vectorization, Pre-lineament Extraction, Image Processing among others. Result showed that 72.38% of the study area is underlain by granitic rocks. The landuse/cover types delineated for the study area include floodplain (29.27%), farmland (23.96%), sparsely vegetated land (15.43%), built up area (13.65%), vegetated outcrop (8.48%), light vegetation (5.37%), thick vegetation (2.39%), water body (0.58%), plantation (0.50%) and mining pond (0.37%). Landslide Susceptibility Analysis also revealed that 87% of the study area is relatively at low to very low risk of landslide event. While only 13% of the study area is at high to very high risk of landslide event. The study revealed that the susceptibility of landslide event is very low in the study area. However, possible landslide event in the hot spots could be pronounced and could destabilize the natural and man-made environmental systems of the study area.
