Volcanoes Around The World

The map shows some volcanoes that have been active in the last 10,000 years. Many more active volcanoes are known to exist on the sea floor, shown here as paler areas in the oceans.

This pattern suggests that magma is only produced in certain places, particularly at the edges of the slowly-moving Tectonic Plates that form the outer layer (lithosphere) of our planet.

Yellow triangles have links to further information about individual volcanoes. Much more information can be found from a couple of sites in the 'Useful Links' section.
