Research Interests

Ionospheric Seismology

Thanks to technological advances over the past fifteen years the ionosphere has today become the new sensitive medium to seismc events. Surface waves (Rayleigh and tsunami) emitted after large earthquakes are known to induce, by dynamic coupling, atmospheric infrasonic and gravity waves propagating upward through the atmosphere. These waves growing up to the top of the atmosphere are strongly amplificated by the effect of exponential decreasing of density with altitude. Ionospheric Seismology may thus turn out to be a useful new tool in investigating mantle tomography, seismic activity in others planets and improving tsunami detection & ocean monitoring.
