Abstract: The 2011 Tohoku Earthquake of Mw 9.0 occurred and its tsunami attacked Japan. The tsunami warning issued by the Japan Meteorological Agency(JMA) was underestimated unfortunately. JMA updated the warning immediately by using tsunami waveform observed by GPS-mounted Buoys. Takahashi and Konuma (2007) pointed out that the present tsunami warning system would be underestimated for huge earthquakes around Mw 9.0. In this study, tsunami numerical experiment for more than three thousands earthquakes in the Nankai Trough was carried out. A model to estimate earthquake magnitude and to avoid the underestimation of tsunami warning by using GPS-mounted Buoys is proposed. And it was shown that the observed water levels by the GPS-mounted Buoys could estimate the maximum water levels at cities.
