The slide has occurred due to oversaturated of loose SFM composed of unconsolidated soil intermixed with rock fragments of country rock), due to rainwater leading to increase in pore pressure and loss of cohesion.

1. Removal of uprooted plants and loose material occurring at critical angle. 2. Construction of broken and damage wall. 3. Provision of hill side drainage. 4. Plantation of bamboo, vetiver on slope surface to prevent erosion.
1. SFM is composed of unconsolidated soil intermixed with rock fragments of country. 2 During rainfall the SFM got oversaturated leading to increase in pore pressure and loss of cohesion and failed. 3. Minor drainage dissection on the affected slope.
