Landslide and Landslide prone areas in India
- Landslides, a type of mass wasting, is defined as the rapid movement of a mass of rock, debris, or earth down a slope.
- Landslides and avalanches are among the major hydro-geological hazards that affect large parts of India besides the Himalayas, the Northeastern hill ranges, the Western Ghats, the Nilgiris, the Eastern Ghats and the Vindhyans, in that order, covering about 15 % of the landmass.
- Himalayas and Western Ghats are particularly susceptible to landslides due to hilly topography and heavy rainfall. (Reason: The northward movement of the Indian plate towards China causes continuous stress on the rocks rendering them friable, weak and prone to landslides and earthquakes.)
Causes of landslides
- Natural: Heavy rainfall, undercutting of slopes due to flooding or excavation, earthquakes, snowmelt etc.
- Anthropogenic: Overgrazing, soil erosion due to loss of vegetation, terrain cutting and filling, excessive development etc.
Effects of landslides:
- Loss of life and infrastructure, cultivable land etc.
- Disruption of traffic and isolation of habitations in hilly regions.
- Floods due to diversion of river courses, channel blockages or reducing effectiveness of dams by adding silt load.
Recent examples of landslides
- Varnavat landslide, Uttarkashi District, Malpha landslide Pithoragarh district, Okhimath landslide in Chamoli district, UK and Paglajhora in Darjeeling district as well as Sikkim, Aizawl sports complex, Mizoram.
Initiatives taken by the Government to mitigate the risk of landslides
- National Landslide Risk Management Strategy (2019): Components:
- Hazard Zoning.
- Preparation of Mountain Zone Regulations: Formulation of land use policies and enforcement of building regulations.
- Stabilization and Mitigation of Landslide and Creation of Special Purpose Vehicle (SPV) for Landslide Management.
- National Guidelines on Landslides and Snow Avalanches:Formulated by the National Disaster Management Authority (NDMA), these guidelines provide comprehensive direction for mitigating the risk arising from landslides across all levels.
- Landslide Atlas of India:The Landslide Atlas of India serves as a comprehensive resource detailing landslide occurrences within India’s landslide-prone regions.
- This document includes damage assessments of specific landslide locations. Prepared by the National Remote Sensing Centre (NRSC), a division of ISRO.
