The Marsili volcano, located in the Tyrrhenian Sea north of Sicily, has become a focus of scientific study following seismic activity in the Sicilian and Aeolian Islands regions. While experts have not confirmed a direct correlation between recent earthquakes and the volcano, research continues into its potential hazards. Geological assessments indicate that the primary threat from the volcano is not lava, but rather the risk of mega-tsunamis. These waves, which could potentially reach heights of 200 meters, may be triggered by massive underwater landslides or a collapse of the volcanic structure itself. As Europe’s largest submarine volcano, the Marsili rises significantly from the seabed, making its structural stability a key concern for Italian coastlines. Recent seismic activity in Sicily and southern Italy has renewed discussions regarding the geological risks posed by both Mount Etna and the Marsili volcano. Experts have clarified that recent earthquakes are tectonic in nature and are not linked to magma movement. While the volcano remains quiescent, scientists warn that a sudden eruption could trigger tsunamis with wave heights of 20 to 40 meters. Such an event could potentially impact the coasts of Basilicata, Campania, Sicily, Calabria, and Sardinia.
