Abstract
Focusing on the scattering waves excited at seamount chains, this study aims to investigate the delay of maximum tsunami to Pacific coast of Japan by integration of numerical analysis and analytical solution by Longuet-Higgins(1967). The results imply that Emperor seamount chain is one of major factors to excite scattering waves to Japan, and the later-phase tsunamis by the magnitude 8 class earthquakes from Hokkaido, Kuril and Alutian islands possibly affect to Pacific coast of Japan. Throughout the results, we discuss the issues to improve the accuracy of tsunami forecasting.
