Solid Earth Geophysics

Core competence

Crust and Mantle Structure using Gravity, Magnetic, Deep Seismic Sounding, Magneto-Tellurics and Seismological tools like body and surface wave tomography, Receiver functions.

Significant contributions

  • Mechanism of seismicity and subterranean sounds in the northwest Deccan Volcanic Province of India.
  • Rupture process of the 3 January 2016 (MW 6.7) Imphal Earthquake.
  • Documenting the role of mantle derived fluids in the genesis of Intraplate earthquakes in the Kachchh rift basin.
  • Characterizing surface geology, liquefaction potential and maximum intensity in the Kachchh seismic zone through ambient noise analysis.
  • Detailed crustal structure of Cambay and KRB using high resolution gravity data.
  • 2-D group velocity distribution maps in the northwest Deccan Volcanic Province of India using fundamental Rayleigh and Love waves.

Current pursuits
