Where are the zones of high volcanic activity?
Brian Lindquist
Dear Brian,
Most volcanoes are located above subduction zones, places where ocean
plates are pushed beneath the edges of other plates. Because the rim of
the Pacific Ocean is nearly surrounded by volcanoes and subduction zone
it is often called the "Ring of Fire." For a simple map showing the
global distribution of volcanoes visit "Location of Plate Boundaries" in
the background information on Plate
Tectonics.
