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 . 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.

Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the seafloor, at what is called a hot spot. While the hot spot itself is fixed, the plate is moving. . On the surface of the earth, nothing can move along a straight line, instead the plates rotate around a point on the surface. Plate tectonics are odd because they often consist of oceanic and continental crust. Geologically speaking, the Philippine archipelago was formed by volcanic eruptions from under the sea and the buckling of the earth's crust when two tectonic plates collided about 65 million years ago. As the Pacific Plate continues to move west-northwest, the Island of Hawaii will be carried beyond the hotspot by plate motion, setting the stage for the formation of a new volcanic island in its place. 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.
