Abstract
The results of detecting ionospheric disturbances by different methods based on GPS observations during the mega-earthquake in Japan (March 11, 2011) are analyzed. It is shown that different methods of analysis and data processing technologies provide generally similar results and suggest quite a complex morphology of the ionospheric response to this seismic event. We distinguish three types of wave disturbances that appeared in the ionosphere in response to the earthquake: slow gravity waves, acoustic-gravity oscillations, and fast disturbances corresponding to the Rayleigh waves. Such an analysis of the wave phenomena and the comparison between the results provided by different methods has been carried out for the first time.
