The moderately weathered rock mass overlain by thick in-situ soil cover exposed along the road cut section failed during rainfall event. Rainfall events resulted in oversaturation of slope material, increase of pore water pressure and loss of cohesion. T
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
The landslide is located just adjacent to LS No. AR/WKG/83A12/2021/006 and is of the same nature, hence similar remedial measures are suggested.

1. Proper diversion of surface water runoff away from the affected slope face. 2. Construction and regular maintenance of lined hillside drain system especially during monsoon season
1. SFM: affected slope is composed of moderately weathered schist overlain by in-situ soil cover of ~3  m thickness. 2. Slope affected by active rill erosion. 3. Saturation of overburden and loss of cohesion during rainfall events. 4. Ill-planned modific
