Pacific Plate

The Pacific Plate is an oceanic tectonic plate beneath the Pacific Ocean.

To the north the easterly side is a divergent boundary with the Explorer Plate, the Juan de Fuca Plate and the Gorda Plate forming respectively the Explorer Ridge, the Juan de Fuca Ridge and the Gorda Ridge. In the middle the easterly side is a transform boundary with the North American Plate along the San Andreas Fault and a boundary with the Cocos Plate. To the south the easterly side is a divergent boundary with the Nazca Plate forming the East Pacific Rise.

The southerly side is a divergent boundary with the Antarctic Plate forming the Pacific-Antarctic Ridge.

The westerly side is a convergent boundary subducting under the Eurasian Plate to the north, the Philippine Plate in the middle and the Indo-Australian Plate to the south.

The northerly side is a convergent boundary subducting under the North American Plate forming the Aleutian Trench and the corresponding Aleutian Islands.

The Pacific Plate contains an interior hot spot forming the Hawaiian Islands.
