The Philippine Sea Plate or the Philippine Plate is a
tectonic plate comprising oceanic
lithosphere
A lithosphere () is the rigid, outermost rocky shell of a terrestrial planet or natural satellite. On Earth, it is composed of the crust and the portion of the upper mantle that behaves elastically on time scales of up to thousands of years ...

Philippine Sea
The Philippine Sea is a marginal sea of the Western Pacific Ocean east of the Philippine archipelago (hence the name), the largest in the world, occupying an estimated surface area of . The Philippine Sea Plate forms the floor of the sea. Its ...

Philippine Mobile Belt, which is geologically and tectonically separate from the Philippine Sea Plate.
The plate is bordered mostly by
convergent boundaries:

Izu–
Ogasawara (Bonin) and the
Mariana Islands, forming the
Izu–Bonin–Mariana Arc system. There is also a
divergent boundary
In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent ...

Mariana Plate which carries the Mariana Islands. To the east, the

The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At , it is the largest tectonic plate.
The plate first came into existence 190 million years ago, at the triple junction between the Farallon, Phoenix, and I ...

Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the ...

Izu–Ogasawara Trench. To the south, the Philippine Sea Plate is bounded by the
Caroline Plate and
Bird's Head Plate. To the west, the Philippine Sea Plate subducts under the
Philippine Mobile Belt at the
Philippine Trench and the
East Luzon Trench. (The adjacent rendition of Prof. Peter Bird's map is inaccurate in this respect.) To the northwest, the Philippine Sea Plate meets

Taiwan, officially the Republic of China (ROC), is a country in East Asia, at the junction of the East and South China Seas in the northwestern Pacific Ocean, with the People's Republic of China (PRC) to the northwest, Japan to the northe ...
