The Mediterranean Sea, often perceived as a low-risk zone for tsunamis, is facing an inevitable threat that demands urgent attention. Despite historical evidence and recent modeling technology, the collective imagination has long associated tsunamis with the Pacific and Indian Oceans. However, the Mediterranean basin holds a dark secret: it has recorded the highest number of historical tsunamis, with several impacting France's Côte d'Azur coastline. This reality is particularly concerning given the short evacuation times, which can be under ten minutes in some scenarios. The Boumerdès earthquake in 2003 and the tsunami in Nice in 1979 are stark reminders of how quickly and unexpectedly tsunamis can strike, leaving coastal communities vulnerable. The French national tsunami alert system, while operational, is not foolproof, especially in the case of local tsunamis or those caused by underwater landslides. This is why raising awareness among coastal populations is crucial. The Nice-Côte d'Azur metropolitan area, with its dense urbanization, strong tourist appeal, and busy beaches, is particularly vulnerable. A comprehensive evacuation strategy has been developed, supported by scientific research, to guide people to safe places. However, beyond evacuation mapping, raising tsunami awareness should also include safety drills and public warning signage. The information portal can be applied to other coastlines in France and Europe, both in the Mediterranean and overseas, where tsunami run-up times can be just as short. The initiatives being implemented in Nice are in line with UNESCO's Tsunami Ready international recognition program, which aims to certify territories capable of anticipating tsunami risks, preparing their populations, and coordinating an appropriate response. When facing a wave that can arrive in a matter of minutes, being prepared to evacuate undoubtedly makes all the difference.
