Protection of life and properties from landslide disaster is indispensable in creating a safe environment
for the society.
The national imperative towards safety due to landslide initiation is increasing in view of the higher
rate of human settlement in the
mountain slope across the country. Landslides are significant amongst those hazards that can be
disastrous to human life and
property. It is estimated that economic loss due to landslides may reach between 1-2% of the gross
national product in many developing
countries. Evaluating and mitigating the landslide hazard and risk is a major challenge for the
technocrats and decision makers in the
developing world as 80% of the reported fatalities due to landslide is within the developing countries.
In India, about 0.42 million sq. km or 12.6% of land area, excluding snow covered area, is prone to
landslide hazard. Out of this, 0.18
million sq. km falls in North East Himalaya, including Darjeeling and Sikkim Himalaya; 0.14 million sq.
km falls in North West Himalaya
(Uttarakhand, Himachal Pradesh and Jammu & Kashmir); 0.09 million sq. km in Western Ghats and Konkan
hills (Tamil Nadu, Kerala, Karnataka,
Goa and Maharashtra) and 0.01 million sq. km in Eastern Ghats of Aruku area in Andhra Pradesh. The
landslide-prone Himalayan terrain falls in the maximum earthquake-prone zones (Zone-IV and V; BIS 2002)
where earthquakes of Modified Mercalli intensity VIII to IX can
occur, and thus, are also prone to earthquake-triggered landslides. The most recent example is the
aftermath of 18 September 2011 Sikkim
Earthquake in the Sikkim-Darjeeling Himalayas.

NLSM
Since FS 2014 - 15, GSI has launched and undertook a national programme on landslide
susceptibility mapping - Macro scale (1:50,000) National Landslide Susceptibility Mapping (NLSM)
with an aim to cover the 0.42 million sq. km landslide prone areas of the country. This national
programme was formally launched by Shri Dinsha Patel, Honâble Minister of Mines, Government of
India.

FAQ
What is a landslide?
- Landslide is a physical phenomenon when a part of rock, and/or debris/ soil fall due to
the action of gravity.
- It is caused by a set of terrain-specific geofactors (e.g., slope, lithology, rock
structure, land use/ cover, geomorphology etc.).
