The rock fall occurred due to highly weathered and intersection of joint coupled with steep slope cutting for road construction along NH-313 (Newly constructing Roing - Anini road)

1. Scaling of unstable loose rocks mass along the slope face. 2. Removal of failed material on the road side.
Highly weathered and jointed of rock mass (quartzite) coupled with steep slope cutting for road widening are the primary causative factor for the failure.
