Disaster resilience has become an important agenda after the United Nations proposed the Hyogo Framework in 2005. In order to quantify disaster resilience, several assessment methods were proposed, yet there exists considerable disagreement about measuring and quantifying resilience. This study proposed a two-stage approach that adds disaster-specific indicators as part of an evaluation step to the Baseline Resilience Indicators for Community (BRIC) proposed by Cutter a al. (2010) 191. Through a two-stage approach, we expected to improve the utilization and scalability of the assessment. As a case study, resilience scores responding to maritime hazardous noxious substance (HNS) spill accidents at 17 ports in Korea were evaluated. In consequence, Ulsan and Wando were rated the most and least resilient, respectively. Further, we employed a two-stage approach using linear regression analysis between average leakage amount, as a measure of actual accident damage, and the evaluated resilience scores of ports. These quantitative results can be easily decomposed into sub-indices and stages to provide a rationale for policymakers to efficiently distribute limited resources.
