Abstrakt: A total of ten tsunami events occurred in Aceh Province from 1991 to 2012. This condition confirms that Aceh Province is very vulnerable to tsunami hazards. In 2004, a tsunami occurred due to the activity of the subduction zone on the west coast of Aceh with a magnitude of Mw 9.3. Since the 2004 tsunami, research on tsunamis has increased. The aim of this study is to reconstruct the 2004 tsunami models, to find out which models are suitable for the events of 2004. There are at least five models of earthquake source faults used for tsunami modeling in this study. The tsunami modeling was carried out numerically using the Tohoku University's Numerical Analysis Model Investigation (TUNAMI) programme. The maximum height obtained from the modeling is 58,05 m at the shoreline. The maximum height obtained from the best model is 17,73 m on land. The M5 fault model produced a tsunami height model that best matches the observation results validated by lowest RMS and highest correlation coefficient values. [ABSTRACT FROM AUTHOR]
