This study aims to assess the tsunami hazard in Palu due to the future tsunamigenic event from the Pasigala source region in terms of near-shore and far-field tsunami runup, inundation height and tsunami arrival time along the coastal of Palu. High-resolution topographic and bathymetry datasets were assimilated to achieve more accurate result in smaller grid domain size. Numerical model used Delft3D as known for one of the numerical tools for simulation tsunami throughout the world by previous researcher. Four scenarios were conducted which consists of tsunamigenic earthquake which generate by using Okada Formulation and aerial subsidence as an approach for mimicking hypothetical potential landslide and empirical equation by Murty as supplementary for determine the initial water level based on its volume. 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 tsunami hazard map. Tsunami Hazard Map made to classify tsunami hazard level by existing classification added with estimated building impacted and arrival time ashore on each village in Palu City administrative region.
