Ok, it seems Vesuvius had a huge eruption 2000 years before the Pompeii eruption - and it appears to have been so sudden that remains have been found
in the act of fleeing (much more sudden than its better known eruption). Geologists have found evidence for at least 8 huge Vesuvius eruptions, every
2-3 thousand years.......and it has been 2000 since the last major event.
Beyond this, BBC had a documentary on a couple of weeks ago about Italy's lost towns / buried history. The first episode was around the Bay of Naples
and they found at least 5 other towns in the region that have all either sunk beneath the waves or risen to be destroyed by ground
deformation.......since the Pompeii eruption.
So have have a huge caldera and a much more massively active than suspected Vesuvius causing regular damage in the area.
Some of the towns they dived on indicated pretty sudden destruction. For example, by simply wiping away sand sediments, floors were almost perfectly
preserved. This means that despite being submerged, they didn't have time to weather at the surface first (sudden deluge). This, in turns, indicates
that Campi Flegri "breathes" pretty damn deeply......
