NCS Survey To Study Quakes In Delhi-NCR

  • 06 Jan 2021

  • The National Centre for Seismology (NCS), under the Ministry of Earth Sciences has started a geophysical survey over the Delhi region for accurate assessment of seismic hazards, following tremors in the NCR last year.
  • The NCS will also carry out analysis and interpretation of satellite imageries and geological field investigations for locating the faults in the Earth’s surface.
  • Magneto-telluric (MT) is a geophysical method which is being used to understand geological structure and processes. MT is a natural time variation of the Earth’s magnetic and electic fields to understand geological structure and processes.
  • These measurements are being conducted across three major seismic sources, namely the Mahendragarh-Dehradun Fault (MDF), Sohna Fault (SF) and Mathura Fault (MF).
  • This will help ascertain the presence of fluid, which generally enhances the possibility of triggering of earthquakes.
  • This survey is carried out in collaboration with the Wadia Institute of Himalayan Geology (WIHG), Dehradun.
  • Analysis and interpretation of satellite imageries and geological field investigations for locating the faults are also being carried out. The study is being conducted by the NCS in collaboration with Indian Institute of Technology (IIT), Kanpur.
