One explanation is an abrupt change in the motion of the Pacific tectonic plate, the opposite model states southward drift of the mantle plume that has sourced the chain since its beginning 80 . The Pacific Plate is moving in the northwest direction at a rate of 56 to 102 millimeter per year. The Hawaiian Islands are positioned at the center of the Pacific Plate. 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. In what direction are the Pacific Plate and Antarctic Plate moving? What makes the Pacific Plate unique compared to the other plates?

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). But its an interior hot spot within the Pacific Plate that is responsible for the volcanic activity that occurs here. The Hawaiian Islands are positioned at the center of the Pacific Plate. The Pacific Plate originated at the triple junction of the three main oceanic plates of Panthalassa, the Farallon, Phoenix, and Izanagi Plates, around 190 million years ago. From the figure, it is clear that the current direction of motion of the Pacific Plate is to the West-Northwest. The seafloor of this oceanic tectonic plate is usually marked by a deep trench, which is caused by subduction zones or divergent boundaries with other plates. direction.. The theory claimed that small, long-lasting, exceptionally "hot" areas of magma are located under certain points on Earth. This situation is analogous to that seen in the Pacific Ocean, where discrete islands form over the Hawaiian Hotspot. .

The Pacific Plate contains an interior hot spot forming the Hawaiian Islands. The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other.
