The Tyrrhenian Sea is situated between the Sardiania/Corsican/Scilian Islands and the Italian Coast. All 3 Islands have had Volcanic eruptions in their past Geological history aswell as land upheaval through metamorphic processes.

What struck me today however was the odd-depth that the Tyrrhenian Sea has compared to the rest of its surrounding Oceanographic terrain, yet despite this in its 12,000ft depths there rests a Active Volcano and numerous other Volcanic features aswell as Fumaroles and Crust Deformations.
One would argue that Subtonic Plate collision from the African and European plate is the cause of this, however this effect is causing land upheaval, not a subduction zone as in South America.
The only explanation for this anomalous depth in-par with the resulting terrain is a Caldera-forming event. Its a scientific fact that theres been VEI8 Eruptions at Campi Flegri just East of the Tyrrhenian Sea, on the Napelese Coast near Mt Vesuvius, so "Supervolcanic" Calera eruptions have and do occur in this region.
However given this map, the scale of this Caldera is unprecidented in itself. It wasnt until I put all the Mediterannean and Italian Coastline Volcanoes together that it came out at me. The Tyrrhenian Sea IS the Caldera itself, and given the fact its still active, means there is still a chamber active underneath.

IDK if it's a supervolcano, but if it is then it looks like it'd dwarf both Yellowstone and Toba, the indian supervolcano that went off 70,000 years ago.

A lot of volcanoes are dormant and because they are dormant, people move in to the area where there is really good fertile soil. They take the chance that the volcano will stay dormant. it is a calculated risk. It may be thousands of years more before the volcano becomes active, it may never become active again, or it may start up again next week. Hard to tell, really.

But wasn't yellowstone extinct until recently?.

scary
