Title: Remote Sensing of Ionospheric Perturbations Induced by Earthquakes and Tsunamis Using GNSS

Speaker: Dr.Sithartha Muthu Vijayan, senior scientist,CSIR Fourth Paradigm Institute.

Abstract:

It is well-known that acoustic and gravity waves generated by earthquakes and tsunamis grow in amplitude during their vertical propagation in the atmosphere and perturb the ionospheric plasma. However, there were limitations in observing such perturbations using conventional observational techniques. The advent of Global Navigation Satellite Systems (GNSS) changed the scenario. The number of dual-frequency GNSS receivers established – both in space and ground – for various scientific and navigational purposes, and the massive earthquakes and tsunamis that shook the Earth in the last two decades provided an unprecedented opportunity to detect and study the coseismic and tsunamigenic ionospheric perturbations. Eventually, these studies opened up a new area of research called ionospheric seismology. Being in its infancy, ionospheric seismology demands improvements in both theoretical as well as observational research to obtain maturity. Upon its maturity, ionospheric seismology will make the remote sensing of earthquakes and other planetary quakes possible in addition to filling the crucial gaps in conventional seismology. Further, this multidisciplinary research field is opening up many research opportunities in the domains of ionospheric physics, geodesy, and geophysics. This talk covers the fundamentals and current status of ionospheric seismology including ionosphere-based tsunami early warning, methods for detecting ionospheric perturbations using GNSS, emerging opportunities, and challenges ahead.
