[MIS24-10] Anomalous wave dispersion of distant tsunamis in a coupled system between the self-gravitating elastic Earth and ocean

*Shingo WATADA1 (1.Earthquake Research Institute, University of Tokyo)

Keywords:Tsunami propagation delay, Tsunami phase velocity measurements, Tsunami waveform dispersion, Tsunami initial phase with reversed polarity, Tsunami precursor, DART tsunami records from the 2010 Tohoku?Oki earthquake and

Traveltime delay and waveform dispersion of distant tsunamis that propagated over the Pacific after the 2010 Chilean and 2011 Tohoku-Oki earthquake can be understood as a propagating wave in a unified gravitationally and elastically coupled system between the solid Earth and ocean.
