The slide has occurred due to the development of local hydrostatic pressure and reduction of shear strength on over-saturation of weak overburden material due to incessant rainfall and rill erosion.

1. Provision of hill side road drains. 2. Removal of loose material occurring at critical angle. 3. Planation of fast-growing grass to reduce the soil erosion. 4. Construction of retaining wall for toe support.
1. Slope forming material comprises of rock boulders of parent rock intermixed with soil. 2. Loss of cohesion and saturation of overburden resulting in increase of pore pressure during rainfall. 3. Rill erosion on the affected slope.
