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. Why do the Hawaiian Islands form a chain of volcanoes? In the Pacific, the route of the Hawaii-Emperor volcanic chain has long been used as an indisputable witness to the movement of tectonic plates. 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.
