| Abstract: | Using the method of numerical simulation, we computed the movement track of tsunamis wave which was engendered by Ms 9.0 large earthquake in Okinawa Trough. Features of landform structure of the continental shelf of the East China Sea were analyzed. We indicated that tsunamis wave simulated could propagate on continental shelf of the East China Sea and accord with characters of actual tsunamis wave. |
