Abstract: Panimbang sub-district, located in the subduction zone of the Indo-Australian plate and directly facing Mount Anak Krakatau, is highly vulnerable to tsunami hazards. The region’s geographic location and its coastal topography make it particularly susceptible to the devastating impacts of tsunamis. This study assesses the region’s preparedness to manage tsunami risks using Geographic Information System (GIS) tools to model evacuation routes and estimate potential inundation areas. The research evaluates the effectiveness of the region’s evacuation capacity, considering critical factors such as population distribution, land cover, and the time required for residents to evacuate safely.
The study’s findings indicate that 74.91% of the 512.73 hectares of residential area in Panimbang is at significant risk of tsunami impact, potentially affecting approximately 38,723 people. This high level of exposure underscores the urgent need for tailored evacuation strategies, particularly in densely populated areas, to minimize the risk of casualties. The analysis also highlights the importance of enhancing infrastructure and disaster preparedness plans to increase the resilience of communities most vulnerable to tsunami threats. The research provides valuable insights into the critical elements of tsunami disaster management. It can serve as a crucial reference for future studies focused on improving evacuation routes, shelter planning, and other essential aspects of critical infrastructure. By addressing these areas, future efforts can more effectively safeguard the population in tsunami-prone regions, ensuring a more efficient and organized disaster response that significantly reduces the potential for loss of life and property.
