The Pacific plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km 2 (40 million sq mi), it is the largest tectonic plate. [2] The plate first came into existence as a microplate 190 million years ago, at the triple junction between the Farallon, Phoenix, and Izanagi plates. The Pacific plate subsequently grew ...
[2] The initiation of the spreading between the Nazca Plate and the Bauer microplate to its west, was about 18.5 Ma ago and has been estimated to have had a spreading rate of on average 170 mm (6.7 in)/year. [4] At about 8 Ma, the western boundary of the microplate moved west with part of the Pacific plate becoming annexed to the microplate.
The Pacific plate (carrying the city of Los Angeles) is moving northwards with respect to the North American plate. The Queen Charlotte Fault on the Pacific Northwest coast of North America The Motagua Fault , which crosses through Guatemala , is a transform boundary between the southern edge of the North American plate and the northern edge of ...
The East Pacific Rise near Easter Island is the fastest spreading mid-ocean ridge, with a spreading rate of over 15 cm/yr. [2] The Pacific plate moves generally towards the northwest at between 7 and 11 cm/yr while the Juan De Fuca plate has an east-northeasterly movement of some 4 cm/yr. [3]
The western end of the GSC forms part of the boundary to the clockwise-rotating Galápagos microplate. [3] The eastern section runs for about 600 km from the southern end of the GT to the Inca Transform with a constant trend of N097°E. There are two main segments that overlap with a left-stepping offset with no transform developed at 87° W.
The Pacific Plate began forming when the triple junction at the center of Panthalassa destabilized about 190 million years ago. Panthalassa , also known as the Panthalassic Ocean or Panthalassan Ocean (from Greek πᾶν "all" and θάλασσα "sea"), [ 1 ] was the vast superocean that encompassed planet Earth and surrounded the ...
The Tonga plate begins 2,500 km (1,600 mi) NNE of New Zealand and stretches northward, [4] until the plate ends bounded by the Niuafo'ou plate to the northwest and the Pacific plate to the northeast. The Hikurangi Margin is the extension of the Kermadec–Tonga subduction zone further south down the east coast of the North Island.
The Pacific Plate comprises most of Oceania, excluding Australasia and the western portion of Melanesia. The Pacific Plate, which makes up most of Oceania, is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million square kilometres (40,000,000 sq mi), it is the largest tectonic plate.
