Subduction zones are broad areas where two. plates are moving in opposite directions. The. oceanic plate descends beneath a continental. plate in this example. [See Divergent and. Convergent Plate Boundaries for more-. detailed depictions].
1 First, in most subduction zones, large earthquakes occur at the interface between the two plates, at depths ranging from the earth's surface down to about 600 km. 2  This region, called the Benioff Zone , is used to locate the subducting plate, as shown for the case of Japan on the left-hand side of Figure 2. Second, in most subduction zones, there is an inland volcanic arc running parallel to the trench. 2  But in southern Mexico, the volcanic arc bends away from the trench, at about a 15Â° angle (see Figure 1). 3  Finally, in most subduction zones, giant earthquakes occur every few hundred years or so.
