Five source models along west coast of Sumatra and one for the south coast of Java were conducted for tsunami simulations. Based on those results, waveform characteristics were analyzed. We chose the west coast of Sumatra for waveform analysis because the coast has variation in water depth, morphology and shoreline shape. For making tsunami hazard map, we chose source parameters from the 2006 south Java tsunami event. The target area is Pangandaran Peninsula, one of the most damaged areas attacked by the 2006 event. We will compare the simulation results with the field survey results by Kongko et al. (2006). We want to know how appropriate the simulation results are for the tsunami earthquake event. To simulate near field tsunami propagation, numerical modeling was used. We considered nested areas, in limited area around Padang (Sumatra cases) and Pangandaran (Java case). From simulations, we got results such as tsunami waveforms, run-ups, tsunami heights and inundations. Based on these results, field surveys, and some pictures taken from AMS (American Marine Survey) and Google Earth, we made tsunami hazard maps.
