Expert analysis on tsunami risks in the Mediterranean Sea

Frédéric Leone, a volcanologist and cartographer from Paul Valéry University of Montpellier, published an analysis in The Conversation regarding tsunami risks in the Mediterranean. Although the region is traditionally considered low-risk, Leone notes that historical data and modern simulations indicate past and potential future impact on French coasts. Tsunamis are triggered by earthquakes, submarine landslides, or volcanic eruptions, capable of traveling long distances and causing massive structural damage. The phenomenon can range from a few centimeters to several meters in wave height, with multiple successive waves occurring. Since 1970, tsunamis have caused over 250,000 deaths worldwide, including major events in the Indian Ocean in 2004 and Japan in 2011. Research conducted in Nice and the French Riviera emphasizes that preventative measures and organized evacuation plans are the most effective strategies to protect lives. Leone argues that while the probability is relatively low, the risk is real and requires awareness. The study highlights that the largest wave is not necessarily the first to arrive.
