摘要
运用数值模拟的方法对在冲绳海槽产生9.0级地震,并引发海啸的过程和海啸波在东海浅水大陆架地形上的传播过程进行研究。模拟的结果表明,数值模拟产生的波浪符合海啸波的特点,东海浅水大陆架适合海啸波的传播。
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.
