Abstract: On 29 September 2009 at 17:48:11 UTC a large earthquake of magnitude 8 struck off-shore of the Samoa Islands and generated a large tsunami that destroyed several villages and caused more than 160 fatalities. This report first presents the characteristics of the earthquake and discusses the best estimations for the fault parameters. These are necessary input data for the hydrodynamic tsunami calculations. Then, a comparison between the near-real time systems and the post-event calculations is performed, with an analysis of the observed differences compared with observed tidal measurements. Coarse, detailed and very detailed calculations are presented in order to identify areas of maximum damage. Conclusions are drawn for improvements in the near-real time system.
