Key hydrogeological aspects of landslides in Western Ghats of Maharashtra

Key hydrogeological aspects of landslides in Western Ghats of Maharashtra - pp1225-1233
The frequency and intensity of landslides in the Western Ghats of Maharashtra, India, have increased. The
present study examines the unprecedented series of
landslides in the Choravane watershed in July 2021,
where 94 landslides were triggered by prolonged and
intense rainfall. Many occurred in undisturbed forested
areas, indicating that the landslides are not always associated with human-modified slopes. Our findings
highlight the role of extended rainfall, distinctive lithology of the Deccan Volcanic Province and groundwater dynamics, particularly subsurface saturation and
pore pressure, in landslide initiation. These insights
have implications for hazard prediction and mitigation.
