The slide has occurred due rainwater, freezing and thawing by snow lead infiltration water along the weak planes and saturation of overburden material.

Removal of loose unconsolidated rock material occurring at critical angle from slope face.
1. Rill erosion and flowing hydrological condition on slope surface. 2. Rainwater, freezing and thawing by snow causes saturation of overburden leading to the increase in pore water pressure and reduction of shear strength causing failure.
