India: The Geological Survey of India (GSI) is contemplating launch of a National Landslide Susceptibility Mapping Programme for the entire country by adopting modern technologies such as Geographical Indication systems and remote sensing. The proposed programme will include detailed field inputs for landslide vulnerable tracts in India. S.K. Wadhawan, Director General, GSI, Kolkata, has pointed out that in Tamil Nadu, the Nilgiris and Kodaikanal had been categorised as highly susceptible to landslides. The workshop noted that The Nilgiris had been experiencing landslides since 1824. In recent years, major landslides occurred in the Geddai, Marappalam, Katteri and the Kallar-Burliar sector.
This was disclosed at a two-day Regional Workshop on, ‘Landslide Disaster Management’ for Southern States and Maharashtra, jointly organised by the GSI and the National Disaster Management Authority. Since, landslides in the Western Ghats were triggered by monsoon rains, the intensity and magnitude of the rainfall and its relation to the landslide occurrence would be the thrust areas in landslide studies. Stress would also be on enhancing awareness among people about landslides.
