The slide has occurred due to weak SFM comprised of highly weathered and jointed country rock with soil. During rainfall, oversaturation of SFM leads to increase in pore water pressure which reduced the shear strength and resulted to slope failure.

1. Removal of loose rock blocks at crown and failed material on the road. 2. Construction of toe support retaining wall along the affected road stretch. 3. Provision of hill side road drainage.
1. The SFM predominantly comprised of highly weathered and jointed rock with soil. 2. During rainfall, increase pore water pressure in the overburden material due to oversaturation reduced the shear strength and resulted to slope failure
