Basili 1 and the TSUMAPS-NEAM Team 1 Istituto Nazionale di Geofisica e Vulcanologia, Italy Following the worldwide surge of awareness toward tsunami hazard and risk in the last decade, Europe has promoted a better understanding of the tsunami phenomenon through research projects (e.g. TRANSFER, ASTARTE) and started programs for preventing the tsunami impact along the coastlines of the North-East Atlantic, the Mediterranean, and connected Seas (NEAM) region with the building of the Tsunami Early Warning and Mitigation System (NEAMTWS, coordinated by IOC/UNESCO). An indispensable tool toward long-term coastal planning and an effective design and subsequent use of TWS 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 HumanitarianAid Operations (DG-ECHO), the general objective of TSUMAPS-NEAM (http://www.tsumaps-neam.eu/) is to produce the first region-wide long- term homogenous PTHA map from earthquake sources, and pave 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), in the framework of the agreement between INGV and the Italian Department of Civil Protection (DPC). The TSUMAPS-NEAM partnership, coordinated by INGV, includes nine geophysical institutions from nine different countries spread all over Europe and neighboring regions (Fig. 1). It received formal expressions of interest by a number of end-users, including IOC- UNESCO, several NEAMTWS Tsunami Service Providers and organizations from further neighboring countries. TSUMAPS-NEAM also seeks triggering 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).
