Volcano

For the Doctor Who episode entitled "Volcano", see The Daleks' Master Plan.

A volcano is an opening in a planet's surface, usually mountainous, which allows hot, molten rock, ash and gases to escape from below the surface. The word was coined by Pompeiian Lucius Caecilius Iucundus, on witnessing Vesuvius' eruption in A.D. 79. (DW: The Fires of Pompeii) Vulcan was the Roman god of fire--especially destructive fire--and blacksmithing, and was purported to have a forge beneath the earth.
