Risk assessment is dealing with the spatial determination of the consequences of the tsunami impact on land. The risk analysis is based on two components; on the one hand the determination of the potentially endangered coastal regions and on the other hand the estimation of the vulnerability of the people and the environment in the affected areas.

Based on the results of the modelling of tsunami propagation and inundation on land the affected coastal regions are mapped. The results of the modelled scenarios of the tsunami generation and propagation provide the basis for this.

These maps are combined with the results of the vulnerability analyses. These analyses provide essential information, for whom and where high vulnerability by tsunami disasters exists. To do this, aspects of socio-economic, environmental, physical and cultural domain have to be taken into account. Detailed analyses will be performed for pilot regions along the coastline.
