They build up slowly over time, with hundreds of eruptions, creating many layers. They’re not likely to explode catastrophically. Examples: Hawaii WebLocation. Most explosive eruptions occur in volcanoes above subduction zones, where one tectonic plate dives beneath the other. Eighty to 120 kilometers below the surface, magma forms when the rocks of the mantle melt just above the subducting plate. The magma rises through the mantle, and erupts to form great composite volcanoes such as Vesuvius.
