The formation of the islands involved the movements of three plates which converged in the region, two of them being major plates (the Indo-Australian and Eurasian plates) and one minor plate (the Philippine Sea Plate).
What two particular major plates are found along Philippine archipelago?
The archipelago is located in one of the most active geologic settings on earth. Three major tectonic elements characterize this complex oblique convergence environment; the Philippine Sea Plate, the Eurasian Plate and the Philippine Fault (Fig. 2).
What plates are involved in 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).
What are the different plates that surround the Philippines?
The complex tectonics surrounding the Philippine Islands are dominated by the interactions of the Pacific, Sunda, and Eurasia plates with the Philippine Sea plate (PSP). The latter is unique because it is almost exclusively surrounded by zones of plate convergence.
Is the Philippine plate a major plate?
The Philippine Sea Plate is the one major plate whose Tertiary motion is poorly constrained and whose origin is problematical. Its southern boundary is the Sorong Fault system which is part of a major left-lateral fault system at the northern margin of the Australian plate.
What are the two plates collide with each other?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common.
What type of plate is Eurasian and Philippine plate?
The Philippine Plate, also known as the Philippine Sea Plate, is a small tectonic plate between the Eurasian Plate and the Pacific Plate. The Philippine Sea Plate has an area of approximately 3400 square kilometers.
Which plate pushes the Philippine plate?
To the east, the Pacific Plate subducts beneath the Philippine Sea Plate at the Izu–Ogasawara Trench. To the south, the Philippine Sea Plate is bounded by the Caroline Plate and Bird’s Head Plate.

What are the two tectonic plates that caused such movement in Leyte?
This fault is active and related to the convergence and left-lateral strike-slip motion between the Philippine plate and the Pacific plate, which is being subducted beneath the islands from the east.
Which type of plate tectonic convergence caused the formation of the Philippine archipelago?
Along its western margin, the Philippine Sea plate is associated with a zone of oblique convergence with the Sunda Plate. This highly active convergent plate boundary extends along both sides the Philippine Islands, from Luzon in the north to the Celebes Islands in the south.
What type of plate boundary is found between the Philippine and Pacific plates?
The Philippine Sea Plate. 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.
What are the 3 types of plate boundaries and where are they found?
There are three main types of plate boundaries:
- Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. …
- Divergent boundaries – where two plates are moving apart. …
- Transform boundaries – where plates slide passed each other.
What are major plates?
There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American. The Hawaiian Islands were created by the Pacific Plate, which is the world’s largest plate at 39,768,522 square miles.
What are the tectonic plates found in Asia?
Southeast Asia tectonics involved long-term convergence of various plates, including the proto-Philippine Sea Plate, proto South China Sea, proto-Pacific Plate and the Indo-Australian Plate.
How many tectonic plates are there in Asia?
Five tectonic units are postulated for central Asia. These are: the Siberian block, the East and West China blocks, the Southeast Asian block; and the Indian plate. An unusual phenomenon is noted along the boundary between the Siberian and West China blocks.
