EARTHQUAKE-INDUCED TSUNAMI HAZARD: TSUMAPS-NEAM AND MPTS18 PROBABILISTIC TSUNAMI HAZARD ASSESSMENT (PTHA) J. Selva, R. Basili, S. Lorito, TSUMAPS-NEAM Team, CAT-INGV Group Istituto Nazionale di Geofisica e Vulcanologia, Italy We will review the state of the art concerning S-PTHA (Seismic-Probabilistic Tsunami Hazard Analysis) in the NEAM region (North-eastern Atlantic, Mediterranean and Connected Seas). This will include some S-PTHAbasics, the results of the TSUMAPS-NEAM project, and the ongoing effort towards the Italian S-PTHA, namely the MPTS18 S-PTHA. These efforts constitute the scientific basis for the definition of evacuation zones in Italy in the framework of the SiAM (Sistema di Allertamento nazionale per i Maremoti), the National Tsunami Warning System, constituted by the Istituto Nazionale di Geofisica e Vulcanologia (INGV), the Istituto Superiore per la Ricerca Ambientale (ISPRA) and the Dipartimento della Protezione Civile (DPC), which has a coordination role as well. An indispensable tool toward long-term coastal planning, effective design and subsequent use of tsunami warning system is the availability of a comprehensive Probabilistic Tsunami Hazard Assessment (PTHA). Funded by the European Commission under the auspices of the Directorate General of the European Civil Protection and Humanitarian Aid Operations (DG-ECHO), the TSUMAPS- NEAM (http://www.tsumaps-neam.eu/) project produced the first region-wide long-term homogenous PTHA map from earthquake sources. This effort paved the way for subsequent local tsunami hazard assessments and risk mitigation initiatives. At the Italian scale, these objectives are pursued by the CAT-INGV (Centro Allerta Tsunami - Istituto Nazionale di Geofisica e Vulcanologia), through the realization of MPTS18, the Italian S-PTHA, in the framework of the agreement between INGV and DPC. The TSUMAPS-NEAM partnership, coordinated by INGV, included nine geophysical institutions from nine different countries spread all over Europe and neighboring regions. It received formal expressions of interest by several end-users, including IOC-UNESCO, several NEAMTWS (the NEAM Tsunami Warning and Mitigation System) Tsunami Service Providers and organizations from further neighboring countries. TSUMAPS-NEAM also sought the triggering of common and cross-border tsunami risk management strategies at European level, in clear synergy with the NEAMTWS operations. A term of comparison for such an effort is being provided by the broader-scale results of the UN- ISDR GAR15 (https://www.unisdr.org/we/inform/publications/42809 ) and its updates (Davies et al. , 2017). This synergy is currently being illustrated by the upcoming UNISDR GAR19, and will be further explored by the future activities of the Global Tsunami Model (GTM, www. globaltsunamimodel.org ). The TSUMAPS-NEAM hazard assessment was built upon a community-driven effort adopting state-of-the-art procedures and standards, enriched by some rather innovative/
