The affected area is lithologically weak; comprising mainly of weathered friable sandstone. Modification of slope for road construction and over saturation of loosely packed overburden material during rainfall resulted in development of local pore water

This is a large landslide with high chances of reactivation. Timely and appropriate remedial measures must be taken up in order to minimize the risk involved.
Kepre Tongikro Mongjang slide No.10
Kepre Tongikro Mongjang road section.
1. Moderation of slope gradient may be considered.
2. Revegetation of slope with fibrous roots system plants.
3. Construction of strong concrete retaining wall with sufficient weep holes.
4. Channelling of surface runoff from the upslope portion and dive
1. Anthropogenic activities: illplanned cutting of slope at steep angle for road construction.
2. Weak slope forming material
3.  Incessant or heavy downpour resulted in over saturation of slope forming material.
