This study assessed Seoul's 1km×1km grid-based climate resilience following a recent heavy rainfall disaster, utilizing hotspot analysis to examine spatial resilience characteristics. The comprehensive climate resilience concept considered vulnerability, adaptation, and mitigation. Data from various sources, including the National Geographic Information Institute, Public Data Portal, and Korea Statistics, incorporated factors like population, land, infrastructure, and economy. The grid-based resilience index, ranging from 0 to 100, revealed high and low-value clusters within Seoul. Notably, clusters coexisted and repeated across administrative districts, departing from previous studies relying on such boundaries. The detailed spatial analysis surpassed district-level evaluations. A three-dimensional graph for 2018-2020 incorporated heavy rainfall resilience, damage, and frequency at the 1km × 1km grid unit level. The comprehensive interpretation considered resilience, damage scale, and disaster frequency, presenting implications for analysis and policy.
