Abstract
The present study aims to assess the Tsunami hazard in Palu due to the future Tsunamigenic event in terms of near-shore and far-field Tsunami runup, inundation height, and Tsunami arrival time along the coast of Palu. A numerical model is developed to simulate propagation and inundation in the study area. Four scenarios are conducted, which consists of the Tsunamigenic earthquake and aerial subsidence as an approach for mimicking hypothetical potential landslide. The outcome from simulation such as inundation height each grid points then calculated with building footprint stored data – derivation data from the terrain model to develop a Tsunami hazard map. Preliminary Tsunami Hazard Map is made to classify the Tsunami hazard level by existing classification added with estimated building impacted and arrival time ashore on each village in Palu City administrative region.
