Research Interest:

  • My interest is to figure out the internal structure of the Earth and to study the properties of earthquakes with the help of seismic data. I am also interested in seismicity analysis of intraplate earthquakes to understand the physical processes responsible for it and a degree of clustering of earthquakes in space and time.

Key highlights:

  • Crustal Velocity Models Retrieved from Surface Wave Dispersion Data for Gujarat Region, Western Peninsular India.
  • Passive seismic attribute analysis in parts of Cambay basin, Gujarat, Western India.
  • Intraplate Seismicity along the Gedi fault in Kachchh rift basin of western India.
  • 1D velocity model retrieve for Kachchh, Saurashtra and SSNNL region to obtain precise routine earthquake location.


  • ISR has started geophysical surveys for Geothermal Energy in Gujarat state. ISR has pioneered a technique of 3D MT imaging of crust. Geological faults and crustal structure have been mapped in Kachchh.
  • ISR is carrying out Multiparametric Geophysical and Geochemical studies in Kachchh for earthquake prediction research.
  • ISR has upgraded Gujarat State Seismic Network from 19 online seismic stations to 40.
