Movement along the fault is not smooth and continual, but sporadic and jerky. 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. The plate forms a convergent boundary by subducting under the Philippine Sea Plate creating the Mariana Trench, has a transform boundary with the Caroline Plate, and has a collision boundary with the North Bismarck Plate. The current overall direction of migration of volcanism is towards the southeast, therefore the plate is moving to the northwest. The Pacific Plate is thinner and denser, so it is being thrust underneath the North American plate. These cookies will be stored in your browser only with your consent.

How fast was the Pacific plate moving during the last 1.1 million years between the formation of the Big Island and Maui in cm/year? 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 . (Newer DVD burners use so-called zoned linear velocities, or even constant angular velocity, to avoid very high rotation rates.). There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American. The North American Plate is being pushed west and north west due to sea floor spreading from the Mid Atlantic Ridge (divergent margin). believed that hotspots form where the inner core makes contact with What caused the Pacific Plate to change direction?

This is because tectonic plates collide and sink at these zones of subduction (convergent plate boundaries). They move at a rate of one to two inches (three to five centimeters) per year. The Pacific Plate is being moved north west due to sea floor spreading from the East Pacific Rise (divergent margin) in the Gulf of California. At 103 million km2, it is the largest tectonic plate.
