With Etna and Stromboli erupting I’m wondering if Vesuvius will kick in. I hope not, could cover what wonderful things they have uncovered.
Camping Flegrei, The Phlegrean Fields, is the one to worry about. Imagine putting the Yellow Stone volcano just out side Chicago or Houston.

The upside is, if modern Ercolano were erased, the excavation of ancient Herculaneum would be a lot easier. Too bad about all the death and destruction though.
