Technical documents: summary

The purpose of the TSUMAPS-NEAM project is to provide a regional probabilistic tsunami hazard assessment (PTHA) to the EU Civil Protection Mechanism. This hazard assessment deals only with tsunamis of seismic origin (Seismic-PTHA, S-PTHA). It is conducted at the scale of the NEAM region (North-eastern Atlantic, the Mediterranean, and connected seas), one of the four regions where the UNESCO-IOC Tsunami Programme has set an Intergovernmental Coordination Group. Its results are designed to be suitable for regional comparative screening and prioritization of site-specific assessments and thus, they are not expected to reach the fine-grain detail necessary for local-scale planning. The diagram below illustrates the various actors and actions involved in the development of the tsunami hazard model.

Phase 2, Assessment

(this section will be updated soon…)

The documents below illustrate the project implementation (Stage 1); the input data and codes used for the hazard calculations (Stage 2); the design and results of the second elicitation experiment (Stage 3); the hazard model results, sanity checks, disaggregation, and sensitivity tests (Stage 4). More technical details on methods and specific results of the elicitation experiment are given in the Appendices.

Stage 1: Implementation

Stage 2: Data and Codes

Stage 3: Elicitation

Stage 4: Results


Phase 1, Pre-assessment (June 2017)

The documents below illustrate the overall project design (Stage 1);  the multi-expert uncertainty management protocol (Stage 2 and Stage 3), which is an attempt to formalize how the subjective choices, arising from scientific and technical controversies during the assessment, are dealt with; and the implementation plan (Stage 4) for the hazard calculations. More technical details on methods and specific results of the elicitation experiment are given in the Appendices.
