Magentotelluric Survey

Magentotelluric Survey:

Measurement of the fluctuations in the natural electric and magnetic fields due to solar activity in orthogonal directions at the surface of the Earth for determining the conductivity structure of the Earth at depths ranging from a few tens of meters to fifty kilometers.


  • Magnetic field sensors ( MFS-06)
  • Electric field sensors:
  • Digital DATA acquisition system
  • GPS timing system


  • Identification of the faults and their directions
  • Identification of the Geothermal regions
  • Identification of the oil and gas reservoirs
  • In the detection of ore bodies e.g. sulphide deposits and copper deposits

Electrical Survey

Time Domain Electromagnetic Survey


  • 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.
