Abstract
The numerical conditions when a numerical simulation of the Indian ocean tsunami in the Maldives isperformed, are decided, and the results of thenumerical simulation of linear dispersivewave equation are compared with tide records. The numerical simulation made the followings clear: (1) The tsunami energy contains longerperiod components preeminently, and1 minute grid size is required fora simulation propagating to the atolls. (2) Numerical results agrees with tide records at Male', but Gan and Hanimadhoo are not enough. (3) The dispersion effect has tobe considered far from Diego Garcia.
