Abstract

In this paper, work was carried out to simulate three-dimensional (3-D) tsunami run-up from high resolution remote sensing satellite data of QuickBird. In doing so, the tsunami wave spectra are extracted from QuickBird data using two dimensional di Fourier transform (2-DFFT). The tsunami propagation equation was then solved based on the standard Galerkin finite element approach to simulate 3-D tsunmai run-up. The results of this study have shown that the integration between different mathematical and numerical models is providing accurate 3-D reconstruction and simulation for tsunami run-up.

Key words: QuickBird satellite data, tsunami run-up, 2-DFFT, 3-D reconstruction, finite element method, Galerkin finite element.
