N2 - How the tsunami hazard affecting life in Palabuhanratu District is investigated in this paper. By considering this district as a tourist area that is visited by many tourists, the coastal activity is quite high compared to other areas. In the southern region of Java Island, or more precisely Pelabuhanratu, there is an active tectonic zone that can cause underwater earthquakes with a potential strength of up to 8.7 Mw. An underwater earthquake of this magnitude can cause a large tsunami potential, which will greatly affect or even paralyze community activities in coastal areas. This study is conducted to analyze the impact of a potential tsunami that could occur on community activities in the area. To achieve this, it is necessary to do tsunami modeling with numerical methods using the COMCOT v1.7 software on two scenarios. Then the results of the visualization of the inundation will be overlaid with land cover data and buildings data in Palabuhanratu District. The results of this study indicate that the tsunami immersion height in the first scenario modeling is much higher than the second scenario, which is more than 30 m. Meanwhile, for the second scenario, it reaches more than 4 m. The potential for this tsunami caused several losses to the residents, namely the residential area of 917.51 ha is submerged and 17,709 buildings affected in the first scenario, as well as the residential area of 260.54 ha is submerged and 2,779 buildings affected in the second scenario.
