Marsili
Marsili Volcano is a large submarine stratovolcano located in the Tyrrhenian Sea, about 175 kilometers south of Naples, Italy. It is the largest volcano in Europe and one of the largest in the world.
Geology: Marsili rises about 3,000 meters from the seafloor, reaching a minimum depth of about 85 meters below sea level at its summit. The volcano is part of the Aeolian volcanic arc, formed by the subduction of the Ionian Sea crust beneath Calabria. Its composition is primarily basaltic and andesitic, reflecting the magma source within the subduction zone. Eruptive activity has been characterized by effusive lava flows and explosive eruptions, although historical records are limited due to its submarine location.
Potential Hazards: Marsili poses a potential geohazard due to the risk of submarine landslides and tsunamis. The instability of the volcanic edifice, coupled with the potential for explosive eruptions, could trigger large-scale landslides that displace significant volumes of water. The resulting tsunamis could impact the coastal areas of southern Italy. Ongoing research and monitoring are crucial to assess and mitigate these risks.
Research and Monitoring: Marsili is the subject of ongoing research efforts, involving seismic monitoring, seafloor mapping, and geochemical analysis. Researchers are working to understand the volcano's magmatic system, its current state of activity, and the potential for future eruptions and landslides. This information is vital for developing effective strategies for hazard assessment and risk mitigation.
