In 1991, the Institute has established its new centre, dedicated to the study of the equatorial upper atmospheric phenomena, at the suburbs of Tirunelveli, India. The center, named as Equatorial Geophysical Research Laboratory (EGRL), has been functioning under the Institute and also involved in recording continuous geomagnetic data in the dip equator.


Dr. K.S. Krishnan Geomagnetic Research Laboratory (KSKGRL) Jhunsi Allahabad, a regional center of IIG, was inaugurated on 27th March 2008. Unveiling of plaque at KSKGRL was done by the chief guest, Dr. T. Ramasamy, Secretary, Department of Science and Technology (Govt. of India) in presence of Prof. B.M. Reddy, Chairman, Governing Council, IIG and Prof. Archana Bhattacharyya, Director, IIG. The function was also attended by IIG’s Governing Council members: Dr. V.P. Dimri, Director, NGRI, Prof. Sri Niwas of IIT, Roorkee, Shri P. Pandian, Financial Advisor of the DST and Dr. D.R. Lakshmi, Member of RAC, IIG. Director, IIG, emphasized the need for establishment of KSKGRL at Allahabad for the development of Palaeomagnetic, Magnetic-petrology, Geomagnetic research and also Upper Atmospheric studies using data generated by Digital ionsonde, Airglow and ionospheric scintillation observations. These investigations are expected to provide vital information about the earth’s deep interior as well as the upper atmosphere and Solar terrestrial relations.


Indian Institute of Geomagnetism (IIG) has taken a new initiative in establishing the Shillong Geophysical Research Centre (SGRC) as its third regional centre. The focus of research at this newly formed centre at Shillong would be on deciphering the pre- and co-seismic signatures in various atmospheric regions over the North-East India using a variety of observational techniques aided by numerical modelling tools. SGRC is functioning from Wilton Hall estate, a picturesque location in upper Shillong in Meghalaya. The geographic co-ordinates of SGRC is 25.570N & 91.880E.
