Abstract
The Pohang earthquake raised concerns about the potential occurrence of fire-following earthquake (FFE). The United States and Japan effectively manage FFE risks through ignition and fire-burned ratio assessments. This study introduced a streamlined method for assessing FFE risk by leveraging a public building database (e.g., building registration data). The proposed method was applied to the Pohang regions. Hence, the ignition and fire spread calculation methods employed in the United States and Japan were adapted to suit the domestic database. The method was then implemented in clusters identified in the Pohang region. The fire-burned ratios, accompanied by the covering volume fraction (CVF) for each cluster, were computed using the extracted and newly developed building information. This method was used to evaluate the FFE risks in the Pohang areas.
