A subduction zone is a region where one tectonic plate is being forced beneath another tectonic plate. This process occurs at convergent plate boundaries, where two plates are moving towards each other. Subduction zones are characterized by deep ocean trenches, volcanic arcs, and seismic activity.

A subduction zone is a region of Earth's crust where one tectonic plate moves under another, sinking down into the mantle. This process is responsible for some of the most violent geological events, including earthquakes and volcanic eruptions.
Subduction zones occur when two tectonic plates collide. If one of the plates is oceanic and the other is continental, the oceanic plate will usually be forced to move under the continental plate. This is because oceanic crust is denser than continental crust. As the oceanic plate moves down into the mantle, it heats up and melts. The melted rock rises to the surface, forming magma that can feed volcanoes.
The subduction of oceanic crust also creates earthquakes. As the oceanic plate moves down into the mantle, it puts pressure on the surrounding rocks. This pressure can cause the rocks to break, releasing energy in the form of an earthquake.
Subduction zones are found all around the Pacific Ocean. The most famous subduction zone is the San Andreas Fault in California. The San Andreas Fault is the boundary between the Pacific Plate and the North American Plate. As the Pacific Plate moves northward, it rubs against the North American Plate, creating tension. This tension is eventually released in the form of an earthquake.
Subduction zones are a major threat to human populations. Earthquakes and volcanic eruptions can cause widespread destruction and loss of life. In addition, subduction zones can also trigger tsunamis, which are giant waves that can travel across the ocean and cause further destruction.
