For example, the Pacific Plate underlies the Pacific Ocean with the Hawaiian Islands positioned smack dab in the middle. However, the Pacific Plate, Cocos Plate , Nazca Plate and Antarctic Plate move more than 10 centimeters which is the fastest movement rate of all plate tectonics.

The Pacific Plate is almost entirely oceanic crust, but it contains some continental crust in New Zealand, Baja California, and coastal California.

[3], The Pacific Plate has the distinction of showing one of the largest areal sections of the oldest members of seabed geology being entrenched into eastern Asian oceanic trenches. The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. As these two plates pull apart from each other, it forms new oceanic crust. From the figure, it is clear that the current direction of motion of the Pacific Plate is to the West-Northwest.
