GNSS ionospheric seismology: Recent observation evidences and characteristics (2015, background): “Here the major events were recently investigated, e.g., 2002 Mw = 7.8 Denali earthquake (Ducic et al., 2003), 2003 Mw = 8.3 Tokachi-oki earthquake (Heki and Ping, 2005), 2004 Mw = 9.1 Sumatra earthquake (DasGupta et al., 2006; Heki et al., 2006; Liu et al., 2006; Occhipinti et al., 2006, 2013),…”
Ionospheric electron enhancement preceding the 2011 Tohoku‐Oki earthquake (2011, methodology): “GEONET (GPS Earth Observation Network) is composed of >1000 continuous GPS stations.”
Internal wave coupling processes in Earth's atmosphere (2014, unknown): “Direct effects of the lower atmospheric acoustic-gravity waves on the upper atmosphere are observed distinctly during earthquakes/tsunamis as well (e.g., Heki and Ping , 2005).”
Two‐mode long‐distance propagation of coseismic ionosphere disturbances (2009, background): “Because of the coupling between neutral particles and electrons at ionospheric altitudes, these acoustic and gravity waves induce variations of the ionospheric electron density [Calais and Minster, 1998; Artru et al., 2001; Afraimovich et al., 2001a, 2006; Heki and Ping, 2005; Astafyeva and Afraimov”
From Sumatra 2004 to Tohoku‐Oki 2011: The systematic GPS detection of the ionospheric signature induced by tsunamigenic earthquakes (2013, background): “[21] GPS stations located close to the epicenter are able to map co-seismic ionospheric perturbations visualizing the TEC variations [Heki and Ping, 2005].”
Ionospheric response to earthquakes of different magnitudes: Larger quakes perturb the ionosphere stronger and longer (2013, unknown): “For example, sometimes only negative phase of the N-wave propagating with acoustic speed in the upper ionosphere can be seen on the north from the epicenter in Northern Hemisphere [e.g., Heki and Ping , 2005; Gokhberg et al ., 2011].”
