The slide has happened 16 kms. from Roing and its initiated by extensive slope cut  of toe of the hill slope for road construction  and incessant rainfall may have caused increase of pore water pressure locally.

1.  Reinforced concrete retaining wall of suitable height may be constructed along the affected slopes area with weep holes at regular interval for discharge of excess water. 2. Slope moderation.
1. Extensive slope cut during road construction. 2. Increase of pore water pressure in the thick (3.5m) overburden soil reduced the shear strength and resulted to slope failure.
