[ABSTRACT] Tsunami waves can induce tsunami traveling ionospheric disturbances (TTIDs) of the total electron content (TEC). In this study , we examine the TEC derived by ground-based receivers of the global positioning system (GPS) and identify TTIDs inducec by 2004 Indian Ocean tsunami. Simulations of the COMCOT (Cornell multi-grid coupled tsunami) model and analyses of the circle method, the ray-tracing techniquie, and the beam-forming technique are used to show that TTIDs can be quickly detected and confirmed after the tsunami occurence. Finally, the ionospheric TEC derived by existing ground-based GNSS (Global Navigation Satelite Systems) receiving stations is demonstrated to be useful to support the tsunami early warning system.
