8.8 earthquake tsunami occurred on Feb. 27th of 2010 in Chile was simulated as an example. The fault dislocation of the seafloor was assumed to equal to the initial tsunami wave field, which can be calculated by the formula of fault dislocation in elastic anisotropic half-space. The linear long wave theory was applied as the tsunami hydrodynamic model, and the finite difference method and frog-leap scheme were selected for solving equations. Finally, the accuracy of the simulated results was verified by the observed results in five tide gauges, and the result shows that our developing model is reliable and can be supported for the other research areas such as the tsunami hazard analysis and warning service.
