A crash caused the bend By about 50 million years ago, the northern migration of subduction led to a colossal collision between the island arc at the northern end of the Pacific Plate and the northeast edge of Asia. The areas of rhyolite underlying the Snake River Plain form discrete areas of volcanic activity, rather than one long ridge. Asia is located in which direction from the Equator? To the west of the fault is the Pacific plate, which is moving northwest. A sharp bend in the chain indicates that the motion of the Pacific Plate abruptly changed about 43 million years ago, as it took a more westerly turn from its earlier northerly direction.
