The rock slide has triggered due to adverse condition of rock mass consists of highly jointed and fractured chlorite schist, prolonged infiltration of rainwater through joint planes and saturation of rock mass weakens the rock mass resulting in failure.

1. Trimming of crown scar. 2. Removal of slided material from retaining wall and slope face occurring at critical angle. 3. Provision for hill side drainage.
1. Steep hill slope. 2. Highly weathered and jointed nature of country rock i.e. chlorite schist. 3. Rill erosion on the affected slope face. 4. Infiltration of rainwater through joint planes and saturation of rock mass.
