Naples has multiple options in which volcanoes will destroy it.
That's true - I was at San Martino (a former monastery on a high point in Naples) and when I moved around to take a photo or two, I thought - ooops, another volcano.
I hope not, though, because Naples is a wonderful place and I loved the Napolitanos, probably because I am an ex New Yorker and many of our Italian immigrants were from Naples and Southern Italy. So it's like going home.
