Mythology and Prophecy. The word 'volcano' comes from the little island of Vulcano in the Mediterranean Sea off Sicily. Centuries ago, the people living in this area believed that Vulcano was the chimney of the forge of Vulcan-the blacksmith of the Roman gods.
A volcano is a landform that is formed through the eruption and accumulation of lava and other solid material. It starts as a vent, hole, or crack in the Earth's surface, through which hot molten rock (lava), gases, and tephra erupt. volcano is a landform that is formed through the eruption and accumulation of lava and other solid material.
