This map shows the subduction zones where the Pacific Plate descends beneath North America and Asia. On the maps that show the Hawaiian island chain, note that the motion of the Pacific Plate is essentially parallel to the west coast of North America but nearly perpendicular to the Eurasian plate margin.
