The affected area is composed of friable siltstone and splintery shale. Also the slope is drained by heavy surface runoff during torrential rains. Due to the porous nature of the lithology and the overburden materials (insitu soil), there is extensive pe

Gully erosion of the poor slope forming material (fragmented and deformed shale, siltstone) is the primary cause of the landslide. Therefore, controlling the surface runoff along the affected slopes is very important.
