What are subduction zones primarily known for?

Subduction zones are primarily known for being concentrated with earthquakes. This phenomenon occurs where one tectonic plate is forced beneath another into the mantle, which creates immense pressure and stress along fault lines. The movement of the plates can cause friction and lead to the release of energy that generates earthquakes. This is particularly evident in regions where oceanic plates subduct under continental plates, such as along the Pacific Ring of Fire, which is well-known for its seismic activity.

While volcanic activity is associated with subduction zones due to the melting of the subducted plate, the defining characteristic of these regions is largely the intense seismic activity. Additionally, the formation of new oceanic crust primarily occurs at mid-ocean ridges rather than subduction zones, and while diverse marine life exists in these areas, it is not a primary feature defining subduction zones.
