Assessment of Earthquake Evacuation Shelter Capacity in Seoul: A Geographic Information Systems-Based Analysis of Transient Population Accommodation in Critical Infrastructure

Abstract

This study assesses the capacity of earthquake evacuation shelters in Seoul, South Korea, focusing on their ability to accommodate the transient population, a key aspect of the city's critical infrastructure. Using GIS-based spatial analysis, the research examines population fluctuations across different times of day, weekdays versus weekends, and seasonal variations. The results reveal significant shortcomings in the current shelter infrastructure, with many areas unable to effectively accommodate residents. Larger shelters are found to support more people from nearby regions, whereas smaller shelters often leave many areas only partially accommodated or completely unserved. This persistent issue across various temporal and population changes underscores the need for a comprehensive disaster preparedness strategy. Key recommendations include the strategic expansion of existing shelters, optimal placement of new shelters, and the adoption of advanced technologies for real-time population tracking. Additionally, the study highlights the importance of enhancing public awareness through regular drills and developing urban planning policies that incorporate disaster management. Fostering collaboration among government agencies, private stakeholders, and community organisations is also essential. By addressing these gaps, Seoul can improve its resilience and better protect its residents during seismic events, emphasising the critical need for innovative disaster preparedness strategies in urban settings.
