Fragile slope forming material composed of highly weathered  rock mass of considerable thickness overlain by thin in-situ soil combined with removal of slope’s toe support for road construction activities and rainfall destabilized the natural slope.
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
i. Due to the absence of hill side drain, surface water run off is flowing all along the road ii. A major slide is observed on the right flank of the slide
Koreng-Aalo road Slide 2
NH-13
i. Removal of slide materials to avoid blockage of road and hill side drain ii. Proper diversion of surfave water runoff from the affected slope iii. Construction and maintainence of hill side drain
i. Adverse condition of rock mass.Slope forming material highly weathered parent rockmass intermixed with soil. ii. Drainage dissection on the left flank of the slide which is in flowing condition.
