Sorrento sounds amazing. Are you following the earthquakes? Thats what would worry me I think, however they pretty minor in the scale of things, but it generating some damage.
If it blows once every x hundred years and goes boom every so many thousand years you'd have more chance of winning the lottery.
From what I have read today they need a combination of earthquake, cracks in the right place and pressure in the right spot.
So unless there is a pressure point and cracks there, that's not good. Very interesting time for volcanologists as they are watching it do a pretty standard cycle of activity.
It looking more possible to wake up in the next hundred years. Obviously less fascinating if you live in Naples I guess.
