Implementation of Mitigation measures necessary. Landslide initiation not known, Reactivated in May 2016
NH 54 Ritzawl slide (1)
NH 54, near Ritzawl village
1. Construction of retaining wall at the toe of the slope founded on firm sub-stratum
2. Proper channeling of surface drainage system away from the affected slope face.
3.  Removal of precariously hanging tree to reduce the static loading at the crown.
Geologically, the area is made up of Shale, flaggy sandstone and calcareous rocks of Disang Group. The affected slope consists of thick overburden comprising highly weathered sandstone and in-situ soil. The slide is reactivated and retrogressive in natur
