The affected slope comprises thick column of overburden material of ~5 m thickness. The overburden material composed of in-situ soil resting on the ill-modified extensive slope cut failed due to oversaturation, increase of pore water pressure and loss of
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 height of the under construction retaining wall seems inadequate considering the thick overburden on the slope.

1. Slope dressing. 2. Retaining wall is under construction, however, height of the retaining wall may be increased by about 3 m for proper slope support and to arrest the slide material in case of reactivation of slide. 3. Construction of proper lined hi
1. Slope forming material is predominantly composed of thick column of in-situ soil cover of ~5 m thickness underlain by slightly jointed rock mass (one set of joint). 2. Oversaturation and failure of loose overburden material during rainfall. 3. Ill-pla
