The affected slope comprises of weak slope forming material which developed local hydrostatic pore pressure due to incessant rainfall rendering the weak slope to lose its shear strength. Another contributing factor is the impact of surface water runoff o

1. Construction of drainage ditches (lined hillside drain) along the road (which is at crown portion of the slide) so that water does not flow towards the affected slope. 2. The slope lower to the road in the valley side should be investigated.
Saturation of weak overburden material due to continuous rainfall in the preceding days and development of local hydrostatic pressure in the weak slope forming material rendered the slope to lose its shear strength.
