The PSP subducts toward the northwest along ∼2500 km of the Ryukyu Trench and Nankai Trough and 1500 km of the Philippine Trench (Fig. 1). This dominant force controls the northwest motion of the plate. The plate is surrounded by subduction zones.
Where is Philippine Sea plate located?
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 is Nankai in Japanese?
In Japanese, Nankai means “southern sea”.
How often do megathrust earthquakes occur?
How often do megathrust earthquakes occur? The recurrence time varies from subduction zone to subduction zone. In the Cascadia subduction zone 13 megathrust events have been identified in the last 6000 years, an average one every 500 to 600 years.
What is fault trough?
A fault trough is usually defined as a rock mass lying between more or less parallel faults or fault zones and depressed relative to the masses on each side.
Which plate boundary is formed between the Philippine plate and the Pacific plate?
The Alpine Fault marks a transform boundary between the two plates, and further south the Indo-Australian Plate subducts under the Pacific Plate forming the Puysegur Trench. The southern part of Zealandia, which is to the east of this boundary, is the plate’s largest block of continental crust.
What is the implication of being near a plate boundary?
If we choose to live near convergent plate boundaries, we can build buildings that can resist earthquakes, and we can evacuate areas around volcanoes when they threaten to erupt. Yes, convergent boundaries are dangerous places to live, but with preparation and watchfulness, the danger can be lessened somewhat.
