PIONEERING A NEW FUTURE 49
• IIG scientists have developed a theoretical tool
that has the potential to capture the offshore ‘ahead of tsunami’ signatures in the ionosphere. This technique utilizes acoustic-gravity waves generated in tsunami waves to forecast the arrival of actual tsunami at coastal locations. Identification of earthquake source characteristics using their ionospheric manifestations is another area of research pursued by IIG. A recent study of IIG examined the ionospheric response to the Gorkha Nepal earthquake from the viewpoints of source directivity, ruptures propagation and associated surface deformation over and near the fault plane.
As human kind faces the threat of global climate change, researchers at IIG are engaged in the multi- proxy reconstruction of past climate by analyzing several sediment cores from the Indian monsoon region. IIG is also engaged in identifying potential aquifer zones and in the assessment of groundwater quality in hard rock terrain of Maharashtra as
their social responsibility. Studies using Synthetic Aperture Radar data from Sentinel-1 satellite and near-field GPS data have helped in understanding the magnitude of slip/uplift/subsidence in the vicinity of the Main Himalayan Thrust.
Instrumentation Group: IIG’s instrumentation group caters to the need of the scientists in the development and maintenance of the instruments used in the institute’s observatories. This group developed in-house a low cost proton precession magnetometer with an accuracy of 0.1nT. It also developed a state-of-the-art windows-based data logging system for magnetic field data acquisition.
A 256-core High Performance Computing system has been installed at IIG empowering the scientists to simulate the processes of Sun-Earth interactions.
The institute has been constantly making endeavours to mobilize its resources
by extending scientific and technical expertise as part of its technology development programme.
Consultancies and Services:
Capacity building for scientific research is a major mission of the institute. To attract, motivate and train young talent to undertake research in geomagnetism and allied areas, new initiatives
have been taken by IIG, such as ‘Inspiring Minds of Post- graduates for Research in Earth and Space Sciences’ (IMPRESS) and Dr Nanabhoy Moos Post-doctoral Fellowship for research scientists. •
SCIENCE OUTREACH PROGRAMMES Under the Science Out- reach programme, the institute promotes several scientific exhibitions for students and its faculty. Its students participate in sev- eral state and national level scientific expositions every year. IIG got the distinc- tion of organizing a special
session on 'The
Dynamic Earth
and its Near
and Far Envi-
ronment: New Paradigms', at the 102nd
Indian Science Congress at Mumbai in 2015. IIG with National Geophysical
Research Institute hosted the XVIth IAGA Work-
shop on ‘Geomag- netic Observatory
Instruments, Data Acqui-
sition and Processing’ in
Hyderabad in 2014.
