Applied Earth Sciences
The Earth Sciences Laboratory comprises Geophysics, Earthquake Engineering, Tracer Hydrology, Hydrogeology and Vibration Technology Divisions. The laboratory undertakes studies for foundation evaluation, source and path of seepage, seismic surveillance and seismic design parameters for major projects.


  • Micro earthquake and strong-motion studies for water resources projects
  • Evaluation of site-specific design seismic parameters (accelerograms and response spectra)
  • Delineation and evaluation of bedrock profile for massive water control structures
  • Evaluation of dynamic Young’s and shear moduli of subsurface strata
  • Location of shear zones, faults and buried river courses
  • Location of groundwater resources
  • Delineation of sub-bottom stratigraphy and 3D mapping of sea/reservoir bed Detection of source and path of seepage through structures and their foundations
  • Measurement of earth resistivity for power houses and other applications
  • Detection of burried pipelines, tanks and contaminant plumes
