National Geophysical Research Institute

The National Geophysical Research Institute (NGRI) is a geoscientific research organization established in 1961 under the Council of Scientific and Industrial Research (CSIR), India's largest Research and Development organization. It is supported by more than 200 scientists and other technical staff whose research activities are published in several journals of national and international repute.

Research areas covered by this institute include hydrocarbon and coal exploration, mineral exploration, deep seismic sounding studies, exploration and management of groundwater resources, earthquake hazard assessment, studies on the structure and evolution of the Earth's interior (theoretical studies), geophysical instrument development, geothermal exploration, and the development and application of Artificial Intelligence and Machine Learning techniques for geoscientific data analysis, interpretation, and modeling.The institute also plays a leading role in advancing multidisciplinary Earth science research through the integration of field observations, laboratory experiments, and computational modeling to better understand subsurface processes and Earth system dynamics.
