How far is the Philippine Sea plate from the Nankai Trough?

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.

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.
