Philippine Sea Plate is an oceanic plate surrounded by subduction zones. The plate is moving northwest at a rate of 6–8 cm (2.4–3.1 in) per year towards the Eurasian Plate. [7] [6] Ranken and Cardwell (1984) showed that the rate of convergence increases southwards along the trench. [8] [5] [4] The plate rotates with respect to the pole near ...
Island arc. Island arcs are long chains of active volcanoes with intense seismic activity found along convergent tectonic plate boundaries. Most island arcs originate on oceanic crust and have resulted from the descent of the lithosphere into the mantle along the subduction zone. They are the principal way by which continental growth is achieved.
Geography of the Philippines. The Philippines is an archipelago that comprises 7,641 islands, [ 8] and with a total land area of 300,000 square kilometers (115,831 sq mi), it is the world's fifth largest island country. [ 2][ 3][ 9] The eleven largest islands contain 95% of the total land area. The largest of these islands is Luzon at about ...

[2] [3] [4] At other times, it is used to refer to the islands of the Pacific Ocean that were previously colonized by the British, French, Spaniards, Portuguese, Dutch, or Japanese, or by the United States.
A map of the Philippines showing the island groups of Luzon, the Visayas, and Mindanao. As an archipelago, the Philippines comprises about 7,641 islands [1] [2] clustered into three major island groups: Luzon, the Visayas, and Mindanao. Only about 2,000 islands are inhabited, [3] and more than 5,000 are yet to be officially named.
The Philippines, along with Vietnam, the People's Republic of China (PRC), the Republic of China (ROC), Malaysia and Brunei, is a claimant country in the disputed Spratly Islands of the South China Sea .

Philippine Sea. / 20°N 130°E / 20; 130. 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 × 106 sq mi). [1] The Philippine Sea Plate forms the floor of the sea. [2]
The Philippine Trench (also called the Philippine Deep, Mindanao Trench, and the Mindanao Deep) is a submarine trench to the east of the Philippines. The trench is located in the Philippine sea of the western North Pacific Ocean and continues NNW-SSE. [1] It has a length of approximately 1,320 kilometres (820 miles) and a width of about 30 km ...
