Abstract
Ambon City is an area that has the highest disaster risk index in Maluku Province. The direction of development of residential areas in Ambon City tends to be coastal areas which of course will have an impact on the risk of tsunami hazard. This study aims to spatially model the tsunami hazard and its exposure to settlements in Ambon City. The research variables consisted of land height, slope, distance from the river, and distance from the shoreline. This study uses an overlay technique on the variables that have been assessed and analysed using a Geographic Information System approach. The results of the study show that the tsunami hazard in Ambon City is dominated by a low level of tsunami susceptibility which has a wider area than the medium and high tsunami vulnerability classes, this is because 77.32% of the Ambon City area is at an altitude of > 64 m while the tsunami exposure level in settlements in Ambon City are nominated with a high level of vulnerability with an area of 2,835.33 ha.
