Where Subduction Takes Place?

Subduction zones occur all around the edge of the Pacific Ocean, offshore of Washington, Canada, Alaska, Russia, Japan and Indonesia. Called the "Ring of Fire," these subduction zones are responsible for the world's biggest earthquakes, the most terrible tsunamis and some of the worst volcanic eruptions.

What is a subduction and where does it occur?

Subduction occurs when two plates collide at a convergent boundary, and one plate is driven beneath the other, back into the Earth's interior.

Does subduction occur when continental plates collide?

When two continental plates collide neither plate can be subducted due to their high bouyancy. With this type of collision there are no features such as a subduction zone, trench or acretionary wedge. The collision of two continental plates occurs when a sea becomes narrower until both plates collide.
