Mediterranean Sea faces high tsunami risk through 2052

UNESCO reports a nearly 100 percent probability of a tsunami exceeding one meter in height occurring within the Mediterranean basin during the 30-year period between 2022 and 2052. Jean-Pierre Duval, an official from the UNESCO Tsunami Unit, warned that coastal planning must account for this reality, challenging the common assumption that the Mediterranean is generally free of tsunami risks.

The geological risk is driven by active fault lines in the Ligurian Sea, which can trigger tsunamis affecting the coasts of France and Italy. Due to the enclosed nature of the Mediterranean, waves can reach the shore in less than 10 minutes following a seabed displacement.

A critical safety gap has been identified in France, where the National Warning Center is designed to send its first notification approximately 15 minutes after a potential earthquake. This creates a five-minute delay where waves could strike highly populated areas like the French Riviera before official warnings reach residents or tourists. Consequently, experts are calling for localized resilience policies, including automated decision-making, mapped evacuation routes, and increased public awareness to ensure immediate coastal departure when sea behavior becomes abnormal.
