Stratovolcano erupting, illustration - stock illustration

Illustration showing the interior of an erupting stratovolcano. A stratovolcano has many layers, or strata, that are formed by successive eruptions. The layers build up to form the cone shape seen here. The eruptions are fuelled by lava, originating in the magma chamber, which rises up a central vent. Side vents can also form and break through to the surface. An example of an active stratovolcano is Mount Etna in Sicily, Italy.
