The Philippine Plate is a tectonic plate beneath the Pacific Ocean to the east of the Philippines. The Philippine plate comprises oceanic lithosphere that lies beneath the Philippine Sea, and so is often referred to as the Philippine Sea Plate because most of the Philippines lies on the edge of the Eurasian plate, to the west of the Philippine Sea Plate.
The plate is bounded by the Philippine Trench on the southwest, Taiwan and the Ryukyu islands to the northwest, Japan to the north, the Izu-Ogasawara (Bonin) and Mariana islands to the east, and Yap, Palau, and easternmost Indonesia (Halmahera} to the south. The eastern part of the plate is occupied by the Izu-Bonin-Mariana Arc system and bounded by the Mariana Trench.
The easterly side of the Philippine Sea Plate is a convergent boundary with the subducting Pacific Plate. The Philippine Plate is subducted on the west under the Eurasian Plate, and bounded on the south by the Caroline Plate and Bird's Head Plate, on the north by the North American Plate and possibly by the Amurian Plate.
Subduction of the Philippine Plate under the Eurasian Plate formed the Philippines and Taiwan and continues today. In the northernmost part of the plate, thickened crust of the Izu-Bonin-Mariana arc is colliding with Japan to form the Izu Collision Zone.
The Izu Peninsula is the northernmost tip of the Philippine Plate. The Philippine Plate, the Eurasian Plate (or the Amurian Plate), and the North American or Okhotsk Plate meet at Mount Fuji.
