A rainfall triggered debris slide on a slope predominantly composed of rock overlain by ~1.5 m thickness of in-situ soil cover. The valley dipping J1 plane is chiefly responsible for the translational failure. During rainfall, the overburden material got
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 road stretch along this section is vulnerable to landslides. Hence, adequate mitigative measures must be planned and implemented.

1. Removal of slide debris from the affected slope. 2. Construction and proper maintenance of lined hillside drain. 3. Construction of retaining wall with proper back filler material and weep holes founded on sound sub-stratum.

1. SFM: Slope is predominantly composed of slightly weathered muscovite schist overlain by ~1.5 m thickness of in-situ soil cover. 2. Debris slide caused along the rock and overburden interface. 3. Failure occurred along the valley dipping J1 plane. 4. O
