This shallow translational debris slide is retrogressive in nature. Weak and unconsolidated lithological unit plays a vital role in slope instability in this area. Rocks are highly fractured and jointed, hence the cracks have been acted pathway for water
Neethusree, K. J. and Suma, C. S, 2020. Macro-Scale (1:50,000) Landslide susceptibility mapping in Toposheet no. 83 C/12 and in parts of Toposheets nos. 83 D/5, 9, 13 & 14 in Dima Hasao, Cachar and Hailakandi districts of Assam, East Jaintia Hills distri
This is a multiple type of failure where there are many minor slide on this slope. Hill side drain have been constructed but there is no cementing hence it may collapse during torrential rainfall.

1. Removal of debris and hanging trees from the slope face 2. Terracing can be carried out along with crown easing 3. Retaining wall can be constructed with sufficient weep holes.
Multiple factors affected the slope failure such as: 1. The affected slope comprises highly weathered (W4) sandstone and clay  2. Deep gully erosion 3. Unscientific slope modification for road construction 4. Rocks are highly fractured and jointed 5. Wat
