Here's why:
* Vulcan, the Roman god of fire, was associated with volcanoes.
* Mount Vesuvius is a well-known and historically active volcano.
* Stratovolcanoes are tall, conical volcanoes built up by many layers (strata) of hardened lava and tephra.
Therefore, the name "Vulcan" is directly linked to the type of mountain that is a stratovolcano.
