Share This Story. The largest earthquakes in the world occur along subduction zones, the meeting point of two tectonic plants where one subducts (or sinks) beneath the other. The magnitude 9.2 earthquake in December 2004 is one of the strongest quakes in recent history.hare This Story.

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.
