The slide is due to the extensive slope cut for road construction. Weathering and widening of joint planes causing loosening of blocks. During rainfall, a local hydrostatic pressure developed, reduce the of shear strength of the SFM.

1.Clearing of weathered and potentially unstable material from the slope face. 2.Hillside lined ditches may be constructed and maintained regularly to prevent infiltration of excess water.
The slope modification initiated by road construction and the prolonged percolation of water along the weak planes resulted the planar failure of rock.
