The debris slide has occurred due to slope disturbance for road construction. The development of local hydrostatic pressure and reduction of shear strength on over-saturation of weak overburden material due to incessant rainfall.

1.Clearing of weathered and potentially unstable material from the slope face. 2. Hillside lined ditches may be constructed and maintained regularly to prevent runoff infiltration. 3. Plantation of deep-rooted local plant at the slope surface.
Extensive slope cut and the prolonged percolation of water along the weak planes resulted the planar failure of rock.
