The largest one, the Pacific Plate is moving north west relative to the plate that holds North America, and relative to hot spots coming up through the mantle from below the plates (they generate islands like Hawaii). The Pacific Plate is moving to the northwest at a speed of between 7 and 11 centimeters (cm) or ~3-4 inches a year.

The Pacific plate is sliding past the North American plate.Both move in same direction, but the Pacific plate is moving faster.The result is earthquakes now and then-but no volcanoes. 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. Approximately 43 million years ago, the plate changed its relative direction of motion it had previously been moving in a more northerly direction greater than 43 million years ago.
