Lee, G.; Lee, C.; Shin, H.; Sunwoo, W., and Jun, K.S., 2020. A study for dynamic decision making framework for tsunami evacuation. In: Malvárez, G. and Navas, F.

This study aims to construct a systematic decision making framework, which can apply response plans dynamically for mitigation of casualties by reflecting regional characteristics, based on Tsunami hazard and evacuation route analysis. Tsunami is a serious disaster that can cause an extensive damage and an early prevention of tsunami is crucial for reduction in the number of casualties. In addition, the safety of the residents vary depending on the information of evacuation routes. Therefore, the priority details that must be considered in counter-measures in target area need to be derived through an evacuation routes based on the conditions and the characteristics of local situation. Hazard assessment is determined by considering tsunami inundation and travel time obtained by a numerical model. Finally, a dynamic decision making framework is proposed considering both hazard risk and evacuation route analysis. The outcome from this study will help not only the management of evacuation map, but also the response plan which provides evacuation information based on the characteristics of local area and residents. Therefore, many lives can be protected from tsunami by applying the decision making framework proposed in this study.
