Abstract

Abstract

In this article a tsunami propagation model was built up using the global ocean model GOCTM. This model is based on finite volume discrete method and unstructured triangular Grids. And this is no open boundary condition to be considered. The tsunami event generated by the great Sumatra-Andaman earthquake on 26 December 2004 was simulated with this model. Tsunami source is provided by Alfred Wegener Institute(AWI) in German as the initial surface elevation condition. In order to check the result,we compare model results to tide gauge data from all around the Indian Ocean,to satellite altimetry in selected track. The highest correlation coefficient between model data and tide gauge data is 0.82 proved a good correlation. And the result is satisfactory which prove the GOCTM is suitable to tsunami propagation simulation.
