The Mediterranean Sea, often perceived as a low-risk zone for tsunamis, is facing an impending threat that demands urgent attention. 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 proactive measures to safeguard coastal communities. The historical context is alarming, with the Mediterranean basin holding the highest number of recorded tsunamis, and several impacting France's Côte d'Azur coastline. The French Riviera, with its vibrant tourism and dense urbanization, is particularly vulnerable. The Boumerdès earthquake in 2003 and the Nice tsunami in 1979 serve as stark reminders of the devastating impact of these natural disasters. The short evacuation times, often under ten minutes, emphasize the critical role of coastal communities' preparedness and the limitations of traditional warning systems. France's national tsunami alert system, Cenalt, plays a crucial role in rapid detection and alert dissemination. However, it is essential to educate coastal populations on warning signs, such as felt earthquakes and abnormal sea movements, to ensure timely evacuation. The Nice-Côte d'Azur metropolitan area, with its dense urbanization and strong tourist appeal, poses unique challenges. Evacuation strategies, supported by scientific research, focus on optimized walking routes and refuge sites. The development of a genuine tsunami risk culture is vital, with initiatives like public information platforms and safety drills. The region's vulnerability extends beyond the Mediterranean, as the information portal can be applied to other coastlines in France and Europe. The Tsunami Ready international recognition program, endorsed by UNESCO, aims to certify territories capable of anticipating and managing tsunami risks. As the Mediterranean faces an inevitable tsunami, the focus on preparedness and education becomes paramount. The collaborative efforts between scientists, authorities, and communities are essential to ensure that the region is 'Tsunami Ready' and capable of mitigating the potential devastation.
