This research aims to explore tsunami-prone areas in the Bacan and South Bacan districts of South Halmahera Regency. The findings of this research are planned to assist all stakeholders, particularly in developing disaster risk assessment sheets. To estimate the tsunami hazard map, the susceptibility of the elevation, slope, river distance, and coastal distance was collected. Overlaying thematic maps were used assisted by GIS software. The result shows that the low and very low tsunami vulnerability areas were safe from tsunami inundation predominate in the Eastern part and Northern part of the study area while the area designated as very vulnerable covered 157,10 hectares. These locations may have sustained the most damage from a tsunami catastrophe due to their proximity to the sea, low terrain and slope, and dense population. In consideration of the tsunami disasters in Aceh, we anticipate that tsunami risk maps will support in the initiation of humanitarian and development activities in North Maluku Province.
