The NEAM (North East Atlantic, Mediterranean and Adjacent Seas) region of IOC/UNESCO is known to be exposed to tsunamis and, like other regions of the world, faces increasing levels of risk due to i) continuous development of coastal areas with critical infrastructure, and ii) year-round presence of millions of tourists. In recent years, European researchers have greatly advanced knowledge of tsunami hazards and implementation of operational infrastructure, such as creation of a regional system of candidate tsunami-watch providers (CTWP) and national tsunami warning centres (NTWC). However, significant gaps remain and more effort is needed. ASTARTE (Assessment STrategy And Risk for Tsunami in Europe) aims to develop a comprehensive strategy to mitigate tsunami impact in this region. To achieve this goal, an interdisciplinary consortium has been assembled. It includes all CTWPs of NEAM and expert institutions across Europe and worldwide. ASTARTE will improve i) basic knowledge of tsunami generation and recurrence going beyond simple catalogues, with novel empirical data and new statistical analyses for assessing long-term recurrence and hazards of large events in sensitive areas of NEAM, ii) numerical techniques for tsunami simulation, with focus on real-time codes and novel statistical emulation approaches, and iii) methods for assessment of hazard, vulnerability, and risk. ASTARTE will also provide i) guidelines for tsunami Eurocodes, ii) better tools for forecast and warning for CTWPs and NTWCs, and iii) guidelines for decision makers to increase sustainability and resilience of coastal communities. In summary, ASTARTE will develop basic scientific and technical elements allowing for a significant enhancement of the Tsunami Warning System in the NEAM region in terms of monitoring, early warning and forecast, governance and resilience. Overall, this will lead to the goal of the European/NEAM Horizon 2020 strategy: to foster tsunami resilient communities.
