Anju, S. S. and Gogoi, R., (2020) Macro-scale (1:50,000) Landslide Susceptibility Mapping in parts of toposheets 47E/08, 47F/05 & 47F/06 in parts of Pune and Raigad Districts, Maharashtra.
The slide found active since there is a column of debris material lying just above the crown part. These materials are comparatively loose and can fail in the monsoon time. So proper remedial measures should be assured before the next monsoon time.

Neral-Matheran Ghat road
Clear blocked hill side drain. Removal of loose rock blocks lying over the slope.
Shotcreting of slope is recommended since the rock is weathered (spheroidal weathering).
Reducing the slope angle by benching.
Preparatory Factors: The spheroidal weathering of basalt leads to the loosing of rock strength and loosening of blocks. Accelerating Factors: Oversaturation due to heavy rainfall reduces the cohesive strength of weathered rock materials and thus results
