The West Coast of Banten is one of the tsunami-affected areas in Indonesia. People living in this region have to be aware of the possible tsunami occurrence anytime. PUSGEN 2017 research result indicated that Megathrust of Sunda Strait has the potential to trigger an earthquake up to magnitude 8.8 generated in the seismic gap zone and strengthened the issue of tsunami threats. Therefore, we need a more detail study of these areas. In this study, we use the mathematical model of tsunamis from ComMIT software by NOAA and overlay it with the coastal population density. The outputs of ComMIT software are heights of run-up, inundation areas, and estimated time arrivals. The population density is determined by the housing population density method and the total number of populations divided by the area of settlements. The result is the number of people affected by tsunami obtained from the intersection between the area of inundation and the field of settlements. In Tanjung Lesung, there are up to 134 people affected by the tsunami.
