The shallow translational rock  slide caused due to weathered SFM (Quartzite of Miri Group) along the extensive slope cut.
Nair,V,Athira., Jamir, I., 2022, Remote Sensing based Macro-scale (1:50,000) landslide susceptibility mapping in Toposheets82L/16, 82P/1,2,3,4,5,6 ; 83I/13,14 & 83M/01 covering  parts of West Siang East Siang, Upper Siang, Dibang Valley and Lower Dibang
The right flank of the slide along the road section is also prone to failure

1.Removal of loose detached boulders from the top portion of the affected slope. 2.Wire mesh system to avoid rock fall on the road bench
1.SFM composed of highly weathered and jointed parent rock mass. 2.Saturation of overburden and increase in pore pressure and loss of cohesion during rainfall.3. Ill planned modification of slope.
