However, prior to about 43-15 Ma volcanism migrated more or less due south, therefore the Pacific Plate prior to 43-15 Ma was moving to the north. The current overall direction of migration of volcanism is towards the southeast, therefore the plate is moving to the northwest.

When oceanic and continental plates meet, the denser oceanic plate moves under the less dense continental plate. On the contrary, it seems the hotspot had been drifting rapidly in a southward direction between 80 and 40 million years ago before it came to a complete halt. If the trail of the Hawaiian hotspot is corrected to include this drift, the result implies a largely constant movement of the Pacific plate over the last 80 . Although both plates are moving in a north westerly direction, the Pacific Plate is moving faster than the North American Plate, so the relative movement of the North American Plate is to the south east.
