It results from the subduction of Eurasian Plate beneath the Philippine Mobile Belt along the Manila Trench since early Miocene. The age of volcanoes young towards the south from Taiwan. Subduction started in Taiwan 16 million years ago, but there were still young volcanoes which are dated up to quaternary in Mindanao.
What two plates collide that resulted in the formation of Philippine archipelago?
Formation of the Archipelago
The formation of the original island arcs is believed to have occurred millions of years ago at the southern part of the Philippine Sea Plate. The original island arcs are believed to have later collided with Sundaland forming a series of other islands in the archipelago.
What are the plates that interact together the formation of the Philippines?
The Philippine Sea plate is tectonically unusual in that almost all the boundaries are convergent. The Pacific plate is subducting beneath the Philippine Sea plate to the east while the west/northwestern part of the Philippine Sea plate is subducting beneath the continental Eurasian plate.
How Philippines was formed?
Geologically speaking, the Philippine archipelago was formed by volcanic eruptions from under the sea and the buckling of the earth’s crust when two tectonic plates collided about 65 million years ago.
Which plate boundary is formed between the Philippine plate and Eurasian plate?
The Nankai Trough subduction zone is a typical subduction system characterized by subduction of multiple geological units of the Philippine Sea Plate (the Kyushu-Palau Ridge, the Shikoku Basin, the Kinan Seamount Chain, and the Izu-Bonin Arc) beneath the Eurasian Plate in the southwest of Japan.
What are the consequences of colliding oceanic oceanic plates?
Effects that are found at this type of plate boundary include: a zone of progressively deeper earthquakes; an oceanic trench; a chain of volcanic islands; the destruction of oceanic lithosphere.
Do two colliding continental plates always form volcanoes?
Volcanoes more often occur from the collision of an oceanic plate and a continental plate rather than two continental plates.
What is formed by two tectonic plates moving toward each other?
The collision between two plates that are moving towards each other is called a convergent boundary. … When two continental plates converge the result is the formation of large folded mountains. The classic example is the collision between the Indian plate and the Asia plate. The result is the Himalayan mountains.
What are the different plates responsible for the development of the Philippine archipelago?
The Philippine archipelago is a mature island arc that is at present being accreted to the eastern margin of the Eurasian Plate. It is composed of a complex mixture of terranes (Encarnación, 2004) formed through plate interaction of the Philippine Sea plate, Eurasian Plate and the Indo-Australian Plate (Fig. 4).
Why do plates interact?
Tectonic plates can interact in one of three ways. They can move toward one another, or converge; move away from one another, or diverge; or slide past one another, a movement known as transform motion. All plate margins along which plate movement is occurring have one thing in common—earthquakes.
When was Philippines formed?
The Philippines are named after King Philip II (1527-1598) of Spain. The country was discovered by the Portuguese navigator Ferdinand Magellan in 1521 (while in Spanish service). Later tension arose between Portugal and Spain and in 1542 Spain re-claimed the islands for themselves, naming them after its then king.
What is the old name of Philippines?
The Philippines were claimed in the name of Spain in 1521 by Ferdinand Magellan, a Portuguese explorer sailing for Spain, who named the islands after King Philip II of Spain. They were then called Las Felipinas.
Which tectonic plate is colliding with the South American plate?
The ongoing subduction, along the Peru–Chile Trench, of the Nazca Plate under the South American Plate is largely responsible for the Andean orogeny.
