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.

Identifying the worst case scenario in the study area in terms of tsunami impact and collection of the needed data for the numerical simulation of the impact. The activities will be performed by GIS mapping.

Deliverables	Title	Type	Timing
	Tsunami Scenario Selection - Data Collection	Data to be sued for the study	M1

Task 2 - Determination of Inundation Zone.

Detecting the inundation zone by a numerical simulation of the tsunami with respect to the identified scenario. The activities will be performed by GIS mapping.

Deliverables	Title	Type	Timing
	Determination of Inundation Zone	Maps and methodology	M2

Task 3 - Ex-ante Loss Assessment: People Affected and Economic Losses related to damaged buildings.

Performing an ex-ante evaluation of the expected impact in the tsunami inundation zone. The assessment will be performed with respect to the people potentially affected and expected economic losses due to damaged and destroyed buildings.

Deliverables	Title	Type	Timing
	Ex-ante Loss Assessment: People Affected and Economic Losses due to damaged buildings.	Results and methodology	M2.5

Task 4 - Results Evaluation -Applicability to other Hazard Types.

Assessing the results with respect to the data needed for the simulations and the uncertainty in the outcomes related to the resolution of the data. Identify the key relevant outcomes for the reproducibility of the methodology.

Deliverables	Title	Type	Timing
	Results Evaluation - Applicability to other Hazard Types	Results and proposed methodology	M3

Task 5 - Identification of the key recommendations.

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 report will provide detailed explanation of the methodology implemented to extract input for indicators related to the Sendai Framework.
