ABOUT NATIONAL INSTITUTE OF DISASTER MANAGEMENT (NIDM)

Background

  • In the backdrop of the International decade for Natural Disaster Reduction (IDNDR), a National Centre for Disaster Management was in 1995.

WHAT IS LANDSLIDE?

  • A landslide is any geologic process in which gravity causes rock, soil, artificial fill or a combination of the three to move down a slope.

What Causes Landslides?

Landslides have three major causes: Geology, Morphology, and Human activity.

  • Geology refers to characteristics of the material The earth or rock might be weak or fractured, or different layers may have different strengths and stiffness.
  • Morphology refers to the structure of the land. For example, slopes that lose their vegetation to fire or drought are more vulnerable to landslides. A classic morphological cause of landslides is erosion, or weakening of earth due to water.
  • Human activity, such as agriculture and construction, can increase the risk of a landslide. Irrigation, deforestation, excavation, and water leakage are some of the common activities that can help destabilize, or weaken, a slope.

LANDSLIDE IN INDIA

Landslide in India

  • In India, 6% of land area (0.42 million sq. km), excluding snow covered area, is prone to landslide hazard.
  • The entire Himalayan tract, hills/ mountains in sub-Himalayan terrains of North-east India, Western Ghats, the Nilgiris in Tamil Nadu Konkan areas are landslide-prone.
  • In Indian terrain, landslide events are mostly triggered by monsoonal rainfall but examples of earthquake-triggered landslide are also not uncommon in India (e.g., Uttarkashi Earthquake, Chamoli Earthquake, Sikkim Earthquake etc.)
