About National Centre for Seismology

  • The National Centre for Seismology (NCS) serves as the primary agency of the Indian government responsible for monitoring earthquake activity and conducting seismological research within the country.
  • Operating as an attached office under the Ministry of Earth Sciences (MOES), NCS plays a crucial role in overseeing earthquake occurrences nationwide.
  • The center operates a 24x7 monitoring center to enhance comprehension of earthquake source processes and their impact on building a society resilient to earthquakes.
  • NCS encompasses different divisions, including Earthquake Monitoring and Services, Earthquake Hazard and Risk Assessments, and Geophysical Observation Systems.
  • It operates and maintains the NSN, or the National Seismological Network. The NSN consists of 153 seismological observatories spread across the country.
  • NSN is capable of recording earthquakes and events of magnitude (M)≥2.5 in and around Delhi, M≥3.0 for the North East (NE) region, M≥3.5 in the peninsular and extra-peninsular areas, and M≥4.0 in border regions.
  • Whenever an earthquake occurs in the country, its information is immediately disseminated by NCS to a variety of user agencies, including disaster management authorities.
  • The NCS shares this information via earthquake bulletins within five minutes of an earthquake.
  • It is also involved in the monitoring of aftershock and swarm activity, if occurred, throughout the country.
  • Another important activity implemented by the NCS is microzonation. It is a site-specific study that provides a more realistic and reliable representation of ground motion characteristics.
  • It is useful in land use and urban planning, as well as in retrofitting of existing buildings.
