Averse condition of rockmass composing of highly weathered parent rockmass intermixed with soil. Rainfall resulted in saturation of fragile overburden material, increase of pore water pressure and loss of cohesion. Extensive slope cut on vulnerable 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
Parent rockmass is highly weathered
West of Kolung Slide 4
NH-513 (Mariyang-Yingkiong road)
i. Removal of slide materials and loose detached boulders from the affected slope ii. Blocked drainage, hence its proper maintenance is required iii. Construction of retaining wall
i. Slope forming material is composed of loose and highly friable parent rockmass mixed with soil ii. Loss of cohesion and saturation during rainfall events.
