Abstract
This study is assessed social and economic vulnerability to natural disasters considering urban characteristics of Seoul. For this study, an indicator-based model, which is composed of 3 sub-indicators and 17 surrogate variables is applied. The 3 sub-indicators consist of demographic and social indicator, secondary damage caused indicator, and disaster preparedness and response indicator, and individual sub-indicators are made up of 6, 5, and 6 related surrogate variables. The spatial resolution of each surrogate variable is built in census output area as possible to reflect the local complexity of population density and wealth distribution. From the results of the application of the model, it can be confirmed that even if the same borough, a variety of vulnerabilities appear depending on the census output area-specific characteristics. Given vulnerability assessment result can be associated with the exposure information of a variety of natural disasters such as floods, landslides, earthquakes, and so on, and its result is expected to be utilized for prioritization of the disaster prevention projects characterized by the specific borough.
