Purpose,Objectives and Scope

The service aims to test methodologies for the estimation of the expected damage level and economic losses to buildings due to the tsunami impact. Since such estimations should be reliable for practical implementation, emphasis will be given to test the dependence of the results on the several parameters and assumptions inserted in the method. The objective is to identify the key recommendations (for modelling and input data), to guarantee the usability and the usefulness of the ex-ante loss assessment for disaster risk management, considering aspects of validity and possibility to extend the developed methodology to other European regions. The service will provide detailed explanation of the methodology implemented to extract input for indicators related to the Sendai Framework.

 

Tasks and Deliverables

Task 1 - Tsunami Scenario Selection- Data Collection.
