The debris slide has occurred along the NH-13 (Anjaw-Tezu road) road due to the extensive slope cut. The prolonged infiltration of water in the SFM has develop a local hydrostatic pressure and reduction of shear strength of the material.

1.Clearing of loose debris material and fragments of rock from the slope face. 2.Construction of hill side drain for excess water discharge. 3.Plantation of deep-rooted species of grass such as vetiver grass on crown and scrap portion of the slide.
Extensive slope cut for road construction. The incessant rainfall over a weak overburden leads to increasing the pore water pressure  and develop a local hydrostatic pressure it reduce the shear strength.
