A possibility scenario of tsunami run-up model in Aceh from potential major earthquake in the Northern Part of Sumatra.

Tsunami modeling is one of the attempted mitigation programs that aim to minimize the impact of losses that may occur due to tsunami disaster. The tsunami modeling is essential to be implemented in areas with tsunami risk zones such as those that rest directly to the subduction route. The main factor that causes tsunami is the earthquake. It can occur in various locations with different mechanisms. The difference in location and the focal mechanism may generate tsunami with different amplitudes of waves and speeds which subsequently inflict different height of waves that come ashore. This study was built upon the numerical simulations of tsunami modeling with multiple scenarios that may occur in the tsunami risk zones by using the TUNAMI-N2. Approximately 30 well-planned scenarios were designed with 21 selected observation point areas were chosen. All of these areas are located on the coast. The results of this study indicate that the range of the vertical wave amplitudes from each different point reaches a significant difference in values. This study also provides the maximum wave amplitudes data from the worst possible scenario for each area on the Aceh coast. [ABSTRACT FROM AUTHOR]
