Approaches for Tsunami Risk Assessment and Application to the City of Cádiz, Spain

Tsunamis can represent a significant risk to the population and cause huge economic damage in many costal regions. In order to be able to identify risk hot spots and implement targeted risk reduction measures decision makers need to have a clear picture of the risk situation in their countries or regions. This work reviews existing methodologies for tsunami risk assessment and makes recommendations on how tsunami risk assessment should be performed. As a case study a qualitative risk assessment for a worst-case tsunami scenario was carried out to understand the tsunami risk to the population in Cádiz. Moreover, a sensitivity analysis of the tsunami hazard input parameters was performed as a strong influence of the variability of the input parameters on the resultant tsunami hazard and risk zonation maps was observed. The study shows that regardless of the assumptions made a non-negligible tsunami risk to Cádiz exists.
