GNGTS 2018 - 37° Convegno Nazionale

GNGTS 2018 S essione 2.1 299 international experiences for the tsunami risk (e.g., New Zealand adopted similar levels), as well as national experiences for the management of other types of hazard/risk. As a next step for the improvement of the national planning against the tsunami risk, the MPTS18 S-PTHA is now being prepared. The basic methodology is the same as that adopted for the TSUMAPS-NEAM model. However, a finer scale needs to be achieved for the national model. This finer scale applies to the parameterization of the tsunami sources and to the discretization of the model output along the coastlines of the Italian territory. Notably, the resolution increase of the source parameter discretization (concerning source position, strike, rake, which were the rougher parameters in the TSUMAPS-NEAM model) is based on the disaggregation of the TSUMAPS-NEAM results, and it is selectively applied only where needed. Furthermore, a higher-resolution set of national tsunami amplification factors has been devised on purpose. Finally, the MPTS18 methodology and results are being discussed in the framework of a participatory review process coordinated by the DPC with a panel of experts appointed by the Head of the Department in accordance with suggestions provided by the Major Risks Commission. When the MPTS18 model will be released, it is desirable that the national planning will be updated accordingly. Acknowledgements.
