The Mediterranean Sea, often perceived as a low-risk region for tsunamis, is facing an impending crisis. UNESCO's recent declaration highlights a stark reality: a 100% chance of a tsunami with a minimum height of one meter in the Mediterranean within the next 30 years. This revelation underscores the need for heightened awareness and preparedness among coastal communities. The Mediterranean's historical record of tsunamis, particularly along France's Côte d'Azur, serves as a stark reminder of the potential devastation. From the 16th century to the early 2000s, approximately twenty tsunamis were recorded in the French Riviera area, with waves often exceeding two meters. The consequences of these events are not just historical; they are a stark reminder of the vulnerability of coastal regions. The Boumerdès earthquake in 2003 and the Nice tsunami in 1979 are recent examples of the devastating impact of tsunamis, with the latter resulting in eight fatalities and significant damage in Antibes, Cannes, and Nice. These incidents emphasize the critical importance of swift evacuation procedures and the limitations of traditional warning systems. The French national tsunami alert system, Cenalt, is a crucial component of the global effort to mitigate the impact of tsunamis. It enables rapid detection of potentially tsunami-generating earthquakes and the transmission of alerts to crisis management centers and the public. However, the system's effectiveness is limited to distant earthquakes, leaving local tsunamis and those caused by underwater landslides vulnerable. This is where community preparedness and awareness become vital. The Nice-Côte d'Azur metropolitan area, with its dense urbanization, strong tourist appeal, and busy beaches, is particularly at risk. The evacuation strategy for this region is comprehensive, incorporating optimized walking routes, refuge sites, and public information platforms. The University of Montpellier's Laboratory of Geography and Land Planning has played a pivotal role in developing this strategy, ensuring that the population is prepared and informed. The 'Tsunami Ready' international recognition program, initiated by UNESCO, further emphasizes the importance of preparedness. This 12-point program aims to certify territories capable of anticipating tsunami risks, preparing their populations, and coordinating an appropriate response. The first towns to receive this certification were Deshaies in Guadeloupe and Cannes, with Nice set to join soon. The Mediterranean's vulnerability to tsunamis is a stark reminder of the need for global preparedness. As UNESCO's declaration underscores, the time to act is now, and the focus should be on raising awareness, implementing evacuation strategies, and fostering a culture of resilience among coastal communities.
