Debris slide documented along NH-217,Tura Dalu Road caused due to the highly weathered gneiss coupled with steep slope cutting and toe removal for road widening. The presence of a major fault (Nerangchi fault) along this zone may be the possible cause of

Removal of loose materials from the slope. Construction of breast wall with sufficient weep holes at the toe of the landslide and construction of lined hillside drainage to arrest further toe erosion.
Highly weathered gneiss with about 1m thick overburden on the upslope of the road is observed. Predominance of this highly weathered gneiss coupled with steep slope cutting and toe removal for road widening. The presence of a major fault (Nerangchi fault
