Okay, I'm over a year late here, but, Local Mafia Boss, Campi Flegrei is a caldera volcano which is partly under the Bay of Naples. In other words, it is a supervolcano, a bit smaller one than the American counterparts Long Valley and Yellowstone, but it also may have a bit bigger risk of an eruption. I was there on a geology field trip during the 80's.

So, Napoli is between two volcanoes, Vesuvius on one side and Campi Flegrei on the other side.
