Question

Quizplus · Accepted Answer

The map shows earthquakes near the Japan Trench, which is a subduction zone where the Pacific Plate is being consumed beneath the Eurasian Plate. The red dots represent deeper earthquakes that occur along the subducting plate, while the yellow dots represent shallower earthquakes that occur in the overriding plate. The fact that shallow earthquakes occur to the east and deeper earthquakes occur to the west suggests that the subduction zone dips to the west.
