A subduction zone is a region where
the oceanic lithosphere descends into the mantle.
Subduction zones produce the majority
of volcanoes observed by humans.
Subduction zone volcanoes are often
explosive and are the world's most dangerous.
Subduction is the result of the old
cold plate sinking below the overriding plate.
Subduction zones have the following
features.
Lisopheric bulge, Deep ocean trench,
Accretionary complex, Forearc basin,
Sedimentary arc, Volcanic island
arc, Back arc basin, Back arc ridge.
