The rock slide occurred due to highly weathered and jointed nature of country rock in which prolonged infiltration of rainwater through joint planes and saturation of rock mass weakens the whole lithopackage resulting in failure.

1. Removal of rock fragments occurring at critical angle. 2. Construction of hill side road drainage. 3. Plantation of bamboo, vetiver on slope surface to prevent erosion.
1. Highly weathered, fragile and jointed nature of rock. 2. Saturation of rock mass and fracture planes leads to weathering and widening of joints resulting in failure.
