The Mediterranean, traditionally perceived as a relatively calm sea compared to large seismic basins like the Pacific, is increasingly consolidated in scientific literature as a zone with real risk of relevant tsunamis in the coming decades.
Different geological studies, historical records, and analyses of underwater activity point to a scenario where, rather than asking if a large tsunami will occur, the question is when the next significant event will occur and with what level of preparedness European and North African coasts will face it.
A Risk Scenario Confirmed by International Organizations
The most cited references come from the Intergovernmental Oceanographic Commission of UNESCO, which maintains that the probability of at least one tsunami exceeding one meter in the Mediterranean in the coming decades is extremely high, to the point of being considered practically inevitable within an approximate horizon of 30 years.
Experts emphasize that it would not necessarily be an extreme event like those recorded in the Pacific Ocean, but rather a phenomenon capable of generating significant damage to coastal infrastructure, ports, beaches, and low-lying urbanized areas.
Scientists insist that the danger in the Mediterranean does not depend solely on the height of the wave. The combination of factors such as high coastal population density, underwater seismic activity, or active geological faults turns even moderate waves into potentially destructive events.
The Most Exposed Areas of the Mediterranean
Studies identify several areas with a higher level of exposure within the Mediterranean and nearby Atlantic environment: the Alboran Sea, the Gulf of Cadiz, the French Mediterranean coast, the Italian coastline, or regions of North Africa.
In the Spanish case, various analyses mention the possible influence of active submarine faults in the southern Iberian Peninsula, where a seismic event could generate waves that reach the coast rapidly.
A 30 to 50-Year Horizon as a Scientific Reference
Scientific consensus does not set a specific date, but rather a recurring timeframe: between 30 and 50 years for the probability of a significant tsunami in the region.
This does not imply that the phenomenon will occur in that exact period, but rather that statistics and historical behavior indicate that in that time interval it is highly probable that at least one event of sufficient magnitude will occur to activate real emergency systems.
