Аннотация:An exact analytic solution of a Cauchy problem for a 2D-wave equation with
a specific axially symmetric initial condition is considered. This solution is used to derive
solutions of more complicated hydrodynamical problems simulating tsunami waves.
Using these solutions, directivity diagrams and wave profiles are computed for initial
conditions that are superpositions of axially symmetric ones, and these superpositions can
excite waves of unusual directivity. A similar effect can be obtained by some successively
activated symmetric initial conditions.
An analytic hydrodynamicalal simulation of Sumatra tsunami on December 29, 2004 is
carried out. The results are compared with some numerical simulation data obtained by other
researchers.
