Earthquake and Delhi

  Earthquakes occur when energy built up in Earth's layers are released along a fault line

Vulnerability of Delhi

  • Himalayas is a weak zone, with zone 5 classification
  • High density of population in excess of 4000 person per sq.km.
  • Mixture of young and old buildings, some are more than 100 years old
  • Lack of adequate spacing; e.g., slum areas
  • Awareness and preparedness of people
  • Lack of capacity of Delhi municipal co-operation

Institutional structure of Earthquake management in India

  • Sendai frame work
  • IMD issues warnings
  • NDMA 2005 institutes an authority
  • Guidelines regarding earthquake
  • Primary responsibility to co-operation, supported by UT, Union and response forces
  • Response, recovery, rehabilitation and resilience model

Drawbacks

  • People resilience is low
  • Uncontrolled urban growth 
  • Buildings are not earthquake resistant

Way forward

  • Building code to be evolved
  • Master plan of expansion to be developed
  • Freedom and flexibility to stick to guidelines
  • Recruitment to NDRF should be through open competition
 India have ~20% geographical area and many cities in zone 4. Careful and visionary planning could enhance resilience to earthquakes. It ensure sustainability of growth.
