The shallow rotational debris slide has been occurred prolonged percolation of rainwater along unconsolidated overburden leads to the increased stress and pore water pressure resulted the slope failure.

Removal of slided material from road. Construction of gabion wall for toe support. Plantation of bamboo, vetiver on slope surface to prevent erosion.
The infiltration of rainwater along the unconsolidated material leads to the increased pore water pressure and reduced the shear strength during rainfall.
