The affected slope dominantly consists of highly weathered sandstone and shale of 2ΓÇô5 m thickness, on a 25╦ÜΓÇô30╦Ü slope gradient. Oversaturation of overburden material during incessant rainfall resulted in temporary increase in pore water

Minor road blocks may also happen in the future obstructing the daily commuters if timely mitigation is not implemented.

1. Moderation of upslope to a stable angle.
2. For proper draining of surface runoff, choked hill side lined drains should be maintained, especially during monsoon season.

Toe cutting of slope, weak overburden material and reduction of shear strain due to oversaturation of material during incessant rainfall are the major geoscientific factors contributing to this failure.
