Slope moderation and benching is required
Naveen Kumar Nigam, Kezhasilie Chiezou, 2022, Remote Sensing based Macroscale (1:50,000) landslide susceptibility mapping in Toposheets 82O/04,8,11,12,15,16; 82P/07 to 11, 13,14 and 83 M/05 covering parts of East Siang, Upper Siang, Dibang Valley and Low
 Slide triggred due to incessant rainfall and extensive slope cutting during road widening, Suitable suggested remedial measures are to be taken.

1. Construction of toe support retaining wall with sufficient weep holes 2. Provision of hill side drain along the affected zone.
  Steep slope due to road construction, widening has led to instability of the highly weathered and jointed rocks without any slope moderation and subsequently failure especially during heavy rainfall.
