The slide has occurred due to weak condition of slope forming material, minor drainage dissection on the affected slope. During rainfall the slope forming material gets oversaturation leading to increase in pore pressure and loss of cohesion

1. Removal of loose material occurring at critical angle. 2. Trimming at crown scar. 3. Construction of retaining wall for toe support with sufficient weep holes and hill side drainage. 4. Plantation of bamboo, vetiver on slope surface.
1. SFM is composed of loose unconsolidated rock fragments intermixed with soil. 2. Saturation of SMF during rainfall leading to loss of cohesion. 3. Minor drainage dissections on the affected slope surface.
