Toe removal of the natural slope during construction of the road resulted in loss of cohesion and failure of overburden material during heavy rainfall under the effect of gravity. Road ward dipping contact/interface between Two differently weathered basa
Rahman, M. A. and Kaur, J., (2020) Macroscale (1:50,000) Landslide Susceptibility Mapping (LSM) in parts of Toposheet nos. 47F/08 and 47F/12in parts of Raigad, Pune,Satara and Ratnagiri districts, Maharashtra.
Fresh morphological signatures such as crown, flanks, surface of rupture indicates the incidence occurred recently. This is a slope cut induced natural landslide with further possibility of failure during heavy rainfall.
