Due to incessant rainfall for about a week in the region, the pore water pressure increased and the weak slope forming material diminished the available shear strength to a point where equilibrium was no longer sustainable in the slope.

Further construction of houses at the crown portion of the slide should be avoided to minimize the potential loss of life and property. Evacuation of residents at the crown portion may be initiated. First occurrence of slope failure on 22/05/2016

1. Construction of reinforced retaining wall at the toe of the slide. 
2. Construction of drainage ditches (lined hillside drain) along the road.
3. Channeling of surface drainage system away from the affected slope.
Saturation of weak overburden material composed of clayey-silt rich soil and weathered sandstone on steep slope and heavy rainfall resulted in development of local pore water pressure in the weak slope forming material and reduced their shear strength.
