Rock slide has occurred south eastern part of the area in Anjaw district. The SFM oversaturated during rainfall increases the pore water pressure and pronounced weathering reduced the shear strength of the slope forming material during heavy rainfall.

1.Clearing of weathered and potentially unstable material from the crown portion of the slide.
The primary causative factor for the slide, predominance of highly weathered quartzite coupled with steep slope cutting and toe removal for road widening.
