INTRODUCTION:

The National Geophysical Research Institute (NGRI) is a geoscientific research organization established under CSIR India in Hyderabad, India in 1961. It is supported by over 200 scientists and other technical staff whose research activities are published in several journals of national and international interest.

Research arenas covered by this institute include hydrocarbon and coal exploration, mineral exploration, exploration and management of groundwater resources, earthquake hazard assessment, structure of earth's interior and its evolution, and geophysical instrument development.

The major areas where research has been carried out are:

Hydrocarbons
Minerals
Groundwater
Eathquake hazard
Lithosphere
Environmental Geophysics

The following are the projects succesfully carried out in NGRI by the eminent researchers and scientists:
