Mount Vesuvius

Mount Vesuvius was a volcano.

Background
The volcano erupted, destroying the ancient city of Pompeii. The archaeologist exam at the Pioneer Scout camp has a question that directly references the volcano. It asks "Alfonso took a trip to Europe and saw the ruins of Pompeii. He learned that a famous volcano erupted, and buried the city in ash. Which volcano?" Mount Vesuvius is the correct answer to the question.

After exiting Vault 76 and entering Appalachia for the first time in 25 years, the overseer encountered some of the region's former residents who had been infected with the Scorched Plague. She studied them from afar, and observed how some had befallen to the Scorched petrification process. She also witnessed that after one stays in a rigid state for a long period, they burn up from the inside, a process she describes as a "Vesuvius in reverse."
