What types of earthquake and volcano patterns are in a subduction zone?

Answer 1

Subduction zones usually refer to convergent tectonic plate boundaries. A convergent boundary indicates two plates that are moving together, or colliding.

Oceanic plates that collide with other oceanic plates will create deep trenchs, such as the Marianas Trench, earthquakes, and/or volcanic islands.

As oceanic plates collide with continental plates, the oceanic plate will always be subducted by the continental plate because oceanic plates are more dense. This type of collision yields a good deal of heat, resulting in volcanic mountains.

Continental plates that collide with other continental plates will crumple on impact producing large mountain ranges, such as the Alps or Himalayas.

Answer 2

Earth quakes tend to be at the fault,and the volcanoes are usually nearby. The earthquakes tend to move the lava up, setting off volcanoes.
