Volcano
A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, ash and gases to escape from below the surface. The word volcano is derived from Vulcano, the name of an island off Sicily which in turn was named after Vulcan, the Roman god of fire. There are at least three volcanic islands in the Caribbean Sea: Padres Del Fuego, Isla Esquelética, and Opau Iato.
