The slope forming material is predominantly composed of slightly weathered and fractured quartzite with phyllite, and overlain by overburden material. Cutting of slope for road construction and dissection of slope by drainages with active erosion played
Kikon, A., and Jamir, I., 2021: Remote sensing based macro-scale (1:50,000) landslide susceptibility mapping in Toposheets 78M/9, M/10, M/11, M/13, M/14, M/15, 83A/2, A/3, A/4, A/7, A/8, A/11, A/12, 83B/1, B/5 & B/9 covering  parts of Tawang, West Kameng
A massive rainfall triggered recurrent landslide occurring since 2018, caused during the initial stage of road construction process due to extensive slope cut.

1. Systematic diversion of natural drainages and surface water runoff from the upslope portion through combined drainages system of chute drain, culvert and lined hillside drain. 2. Construction of strong RCC retaining wall of adequate width and height f
1. Adverse condition of rock mass; predominantly highly fractured quartzite. 2. Hillslope moderately dissected by drainages. 3. Seepage of water along weak planes and saturation of slope material during rainfall events. 4. Ill-planned modification of slo
