This study focuses on assessing the vulnerability of households in Phong Nha town, Bo Trach district, Quang Binh province to flood hazard. A set of 23 indicators for assessing vulnerability to flood was proposed based on three components: exposure, sensitivity, and adaptive capacity. The study area, famous for the Phong Nha-Ke Bang World Heritage Site, has been severely affected by floods. A substantial 81% of households experienced flood damage in 5 recent years in 2019-2023. In particular, the October 2020 flood devastated 85% of households in the town. The study results showed 39% of households have children under five years old and above 65 years old. Regarding adaptive capacity, 56% of interviewed households have basic mitigation tools and only 9.0% actively participate in disaster prevention training course and 4% have property insurance. The values of exposure, sensitivity, and adaptive capacity are 0,67; 0.32; 0.37 in scale 0-1, respectively. The quantitative assessment of the vulnerability of households in Phong Nha town to flood hazard is 0.62 on the scale of -1 and +1, indicating a relatively high level of vulnerability. The results provide a basis for managers to strengthen measures to improve local people's adaptive capacity in preparing for disaster prevention in general and floods in particular.
