Abstract
In urban development, land suitability assessment is very important to be considered by urban planners and policymakers for designing urban spatial planning. Assessment of the suitability of urban planning using a multi-hazard map is made to provide an overview of potential natural hazards that pose a threat to regional development so that the government can avoid urban development in areas prone to natural hazards or implementing urban development based on disaster mitigation. The research area in Mamuju District which is the capital city of West Sulawesi Province and an area that has frequently suffered damages due to floods, landslides, and earthquakes. The main scope of this research is to synthesize natural hazard maps in one multi-hazard map and thus identify suitable areas for urban development using the Analytical Hierarchy Process (AHP) method and utilize Geographical Information Systems (GIS). The results showed that the Mamuju area was mostly at moderate to high suitability.
