The city of Naples, Italy is flanked by two volcanoes. Mt Vesuvius (pictured), famous for its 79 C.E. eruption that covered the city of Pompeii in fire and ash, is one of them.
The other is lesser-known, but arguably more dangerous. Its name is Campi Flegrei, and it dwells beneath the homes of hundreds of thousands of people. Could this volcano’s ever-shifting nature soon reach a breaking point?
