JRC/DG-ECHO/UNESCO-IOC Joint Hybrid-Workshop on Local Tsunami Warning in the context of Multi-Hazard Disaster Risk Mitigation
The classical tsunami warning methodology is based on the reliable identification of earthquake location, magnitude, and depth which generally requires >7 min for the initial tsunami warning because of the seismological constraints. This may sound fast, however, such a warning time may still be late for some coastal locations to take timely actions, where tsunamigenic sources are very near the shoreline. In addition to the historical 1908 Messina Strait earthquake and tsunami, 2017 Bodrum-Kos, 2018 Palu, 2020 Samos earthquakes with very short tsunami arrival times and 2018 Anak Krakatau - 2022 Hunga Tonga-Hunga Ha'apai volcanic origin tsunamis are other events that clearly remind us of the urge for relevant communities to fill the gaps of local/near-field tsunami warning. This report provides a summary of the presentations and discussions of the JRC/DG-ECHO/UNESCO-IOC Joint Hybrid-Workshop organized in JRC-Ispra during 4-5 October 2022, and presents conclusions, which, in line with the target (g) of the Sendai Framework for Disaster Risk Reduction, will support the development of an integrated, truly multi-hazard-oriented coastal community disaster resilience policy brief for Europe. It also showcases that the EEWS system currently being tested for example in Messina and the operational Volcano-TEWS in Stromboli, which directly alert both population and authorities at the same time have clear potentials to be adapted in many parts of the world subject to similar local/near-field tsunami threat.
