Donggala Regency has diverse morphology, encompassing coastal areas and complex hilly terrains. Geomorphological studies are essential for understanding landforms and assessing the potential for related natural disasters. This study aims to identify dominant landforms and assess natural disaster vulnerability, including landslides, tsunamis, and liquefaction, using a Geographic Information System (GIS)-based approach. The methods employed in this research include the analysis of topographic maps, satellite imagery, and a review of literature on geological conditions. The results indicate that coastal areas are highly vulnerable to tsunamis, while hilly regions are more susceptible to landslides.
