Open AccessObservation of ionospheric disturbances induced by the 2011 Tohoku tsunami using far-field GPS data in Hawaii
In this study, we employ far-field GPS total electron content (TEC) observed in Hawaii to detect the ionospheric disturbances induced by the 2011 Tohoku tsunami. We observed tsunami-driven traveling ionospheri...
