c. National Centre for Seismology
d. None. It’s a separate institute with no attachment to other institutes.
ANSWER: Indian Institute of Geomagnetism
To understand better and possibly predict earthquakes, the Indian Institute of Geomagnetism has opened its third regional centre in Shillong, a region, which is highly prone to tremors. SGRC is expected to emerge as one of its kind in the world in unraveling the earthquake processes and generating a precursor model for earthquake predictions in the years to come. 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 using a variety of observational techniques aided by numerical modelling tools. Studies to be undertaken at SGRC will contribute to a better understanding of the earthquake sources and their generation mechanisms leading to an improved characterisation of earthquake occurrence and hazards in the North-East and assessment of threats they pose to the local population. The ultimate challenge is to develop an earthquake precursor model based on varied observations of the atmospheric and ionospheric response to earthquake occurrence in order to build an Integrated Earthquake Precursory Signal System (IEPSS).
