Debris slide documented along Pachhi- Chayang Tajo road section, caused due to the high degree of weathering of rocks and active gully erosion and flowing nalas along the  landslide.
Mohanty, A., and Joshi, K., 2021: Remote sensing based macro scale (1:50,000) landslide susceptibility mapping in toposheets 82D/12, D/15, D/16, 82H/3, H/4, H/6, H/7, H/10, 83A/1, A/5, A/6, A/9, A/10, A/13, A/14 and 83E/1 covering parts of Tawang, West K
Area needs detailed study.

Removal of loose materials from the slope. In between the slope provision of a 2-3m bench will increase the slope stability. Construction of breast wall with sufficient weep holes at the toe of the landslide and construction of lined hillside drainage to
Highly weathered gneiss with about 1m thick overburden on the upslope of the road is observed. Active gully erosion and flowing nalas along the landslide suggests percolation of water and increase in pore water pressure.
