Most people don’t recall that neighboring ‘Herculaneum’ was allso wiped out.
“... the sighting of a column of smoke ... triggered a response more of curiosity than of alarm...”
“... there were warnings of the eruption of Vesuvius.”

One of my regrets is not making it to Pompeii. I was in Naples but there was an earthquake and Pompeii was closed for about 10 years. They were supposed to be starting flights from Granada to Naples in the fall but who knows what’s going to happen now.
