Tsunami risk mitigation: the role of evacuation routes, preparedness and urban planning

This study contributes to the tsunami science by evaluating potential building damages due to shaking and tsunami impact and providing decision support for evacuation strategies. Using Geographic Information Systems (GIS), tsunami scenarios are modeled based on historical seismic events, such as the 1755 Lisbon earthquake, to identify high-risk coastal zones and optimize evacuation routes, considering local topography and population density. Additionally, wave propagation and arrival times are analyzed to ensure timely access to population escape and to mitigate damage to critical infrastructures.

Key objectives of this study include acquiring and implementing historical tsunami data, assessing recommending evaluating the region´s vulnerability, and recommendations for good practices and mitigation measures. The study emphasizes the importance of raising public awareness, enhancing governance, and strengthening capacity to effectively reduce disaster risks.
