The rock slide is due to extensive slope cut along the two prominent joint, are forming a wedge. As well as the percolation of water along joints further leads to the widening and resulted the detachment of blocks along the weak planes.

1.Removal of loose material from the slope surface. 2.The deep hillside lined ditches at toe of the hill slope should be cleaned.
Extensive slope cut and the prolonged percolation of water along the weak planes resulted the planar failure of rock, .
