Numerical experiment of earthquake tsunami in Okinawa Trough
冲绳海槽地震海啸的数值试验研究

We first introduce the geography and geology of East China Sea region,and analyze the probability of earthquake tsunami in Okinawa Trough,then numerically simulating with the finite difference method and discuss the tsunami propagation on East China Sea based on the finite moving source and 1D Boussinesq model.We conclude from the numerical studying that it's cost more than 5 hours for Okinawa tsunami propagating near to Shanghai and the wave attenuated to 10's cm.
