The landslide is basically a cut-slope failure that got triggered due to heavy antecedent rainfall.
Improper/unscientific slope excavation for road widening is largely accounted for the initiation of the landslide. Landslide occurred on 11th July, 2017 at 14:30 hrs.

 1. Slope easing through the removal of loose debris material.
2. A series of berms/benches may be put in place along the cut-slope with adequate protection on the backslope of each bench.
3. Suitable and effective drainage system (lined contour drains a
The saturation of the unconsolidated colluvial cover due to antecedent heavy rains led to drastic reduction in the shear parameters of overburden material. The cutting of road across the slope consisting of loose unconsolidated material also aided to the
