The affected area comprises of weak slope forming material (Thin insitu layer) and highly deformed rocks units. During incessant rainfall, the top thin insitu soil layer could not hold the weight of the overburden material (Bamboo, trees) and resulted in

Toe support for the affected slope through construction of strong RCC retaining wall with sufficient weep holes founded on sound substratum. Construction and proper maintenance of concrete road side drain.
Oversaturation of slope forming material and increase in local pore water pressure. Loose of toe support due to extensive slope cut along NH4. Weak lithology comprised of fragmented and highly jointed sandstone and friable shale
