UNESCO has made a commitment to the scientific community for the creation of the North East Atlantic and Mediterranean Tsunami Warning System (NEAMTWS). We wonder: “Is the European Seismological community ready to run an Euro Mediterranean tsunami warning system?” In this study we use the February 12, 2007 Ml = 6.1 earthquake, which occurred close to the epicenter of the 1755 Great Lisbon event, as a case study to verify and discuss our actual capability of alerting for a hypothetical tsunami. Starting from the available real-time data and tools, we emulate an automatic real-time processing to perform the source analyses needed for discriminating a tsunamigenic earthquake, and subsequently we evaluate the time shift between the release of results and the potential tsunami waterfront reaching the coasts.
