The slide has occurred due to the slope disturbance for road construction in highly jointed chlorite schist and quartzite. Infiltration of rainwater along the weak planes and saturation of rock mass leads to weakening of rock and failure.

1. Removal of slide material from road and from slope surface which is occurring at critical angle. 2. Removal of protruded rock masses and trimming at crown scar. 3. Construction of retaining wall for toe support.
1. Toe cutting of hill slope for road construction. 2. Highly jointed nature of the country rock (chlorite schist and quartzite). 3. Infiltration of rainwater along the weak planes and saturation of rock mass.
