The Philippine Sea plate or the Philippine plate is a tectonic plate comprising oceanic lithosphere that lies beneath the Philippine Sea, to the east of the Philippines.Most segments of the Philippines, including northern Luzon, are part of the Philippine Mobile Belt, which is geologically and tectonically separate from the Philippine Sea plate.
The oceanic Philippine Sea plate subducts beneath the Eurasian plate at the Ryukyu Trench. The oceanic Pacific plate subducts under the oceanic Philippine Sea plate forming the Mariana Trench. The oceanic Philippine Sea plate is subducting under the Philippine Mobile Belt forming the Philippine Trench and the East Luzon Trench.
The Philippine Mobile Belt (also called as Taiwan–Luzon–Mindoro Mobile Belt [11]) is a complex tectonic zone which sits at the convergence zone of the Eurasian plate, Philippine Sea plate, and Indo-Australian plate. [9] It covers the whole Philippine archipelago and extends southwards to the Molucca Sea and eastern Indonesia.
The Manila Trench was formed by the subduction of the Eurasian Plate underneath the Philippine Sea Plate, which initiated during the Middle Miocene (22-25 million years ago). A characteristic feature of this plate boundary is the gradual change from normal subduction (on the southern margin) to a collisional regime (on the northern margin ...
South Bismarck plate – Small tectonic plate in the southern Bismarck Sea; Trobriand plate – Small tectonic plate located to the east of the island of New Guinea; Philippine Sea plate Mariana plate – Small tectonic plate west of the Mariana Trench; Philippine Mobile Belt, also known as Philippine microplate – Tectonic boundary; Scotia plate
Major physiographic elements of the Philippine Mobile Belt Puerto Princesa Subterranean River National Park marker describing the geologic history of the Philippines. In the geology of the Philippines, the Philippine Mobile Belt is a complex portion of the tectonic boundary between the Eurasian plate and the Philippine Sea plate, comprising most of the country of the Philippines.
In the Philippine Sea, the oblique motion of the subducting Philippine Sea plate resulted in the formation of the Philippine trench and the PFZ back arc fault system. The oblique motion is accommodated by two vector components; one vector perpendicular to the converging Philippine Trench and one vector parallel to the PFZ.
The Philippine Sea is a marginal sea of the Western Pacific Ocean east of the Philippine Archipelago (hence the name) and the largest sea in the world, occupying an estimated surface area of 5 million square kilometers (2 × 10 ^ 6 sq mi). [1] The Philippine Sea Plate forms the floor of the sea. [2]
