This event has been named as the “Avellino Eruption” of Mount Vesuvius.
And you can search for more information using that term.
Thanks! Looks like this is the Somma cone eruption event I’d read about years ago. There’s a Roman-era fresco in one of the formerly buried houses showing the pre-eruption Vesuvius with two peaks. The 79 AD eruption, uh, altered that a bit.
“Thousands of footprints in the surge ash deposit of the Avellino eruption testify to an en masse exodus from the devastated zone”

Satellite view, appears to show the older caldera rim, with the current caldera inside it:
