Campanian volcanic arc

• Mount Vesuvius: an active volcano that last erupted in 1944.
• Phlegraean Fields: a huge, ancient caldera containing the western area of Naples. The area is a collection of numerous extinct craters that are evidence of ancient eruptions; however, also included in this area is Solfatara, a shallow volcanic crater still emitting jets of sulfur fumes and, thus, still active.
• Mount Epomeo: 20 kilometres west of Naples on the island of Ischia, it last erupted in 1302.
• Palinuro, Vavilev, Marsili, and Magnaghi: undersea extinct or dormant volcanoes south of Vesuvius. The last three were discovered in the 1950s and bear the names of the geologists who discovered them. Palinuro was known earlier., there was some concern about the state of "dormancy" of Marsili, which is 3,000 meters high with the cone reaching to 500 meters from the surface of the water. Satellite cones of recent origin have been detected on Marsili.
