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 basically a vent from which, magma, gases, and volcanic ash escape to the Earth's surface, through faults in the crust. They may erupt violently like Krakatoa in 1883, or just seep out lava like the Kilauea volcano.ormed as a result of plate tectonics, volcanic eruptions can result in the formation of mountains, craters, crater lakes, plateaus, and islands. Earth is made of four concentric layers-inner core, outer core, mantle, and crust.
