Government launches Seismic Hazard Microzonation to minimize earthquake disasters

2 min read

News:The Ministry of Earth Science has launched Seismic Hazard Microzonation project in major cities of India.

Facts:

Aim of the project:The project aims to reduce hazards of seismic activities by putting in adequate measures.

About Seismic Hazard Microzonation:

  • Seismic Hazard Microzonation is the process of identifying the earthquake prone areas based on its geological and geophysical characteristics.
  • The characteristics include ground shaking, landslides, liquefaction susceptibility, rock fall hazard and flooding caused due to earthquakes among others.
  • Based on this division, mitigation measures and preventive methods are prepared to minimise the losses.

Significance of the project:

  • The technique gives better mitigatory measures as it helps to understand the impact of seismic activities precisely.
  • It can also be helpful in certain places, where no reliable model can be implemented as it helps in adopting preventive measures.

Where has the microzonation completed?

  • Currently,the microzonation has been completed in the State of Sikkim and in other eight cities namely Delhi, Bengaluru, Kolkata, Guwahati, Jabalpur, Dehradun Ahmedabad and Gandhidham.
  • Further,Japan is the best example where microzonation techniques are well implemented.
