Mariana plate boundary. 1 is West Mariana Ridge, 2 is Mariana Trough, 3 is Mariana Arc, 4 is Mariana Fore-Arc, 5 is Mariana Trench. The tectonic plate is approximately 100 km thick and converging to the east at a rate of 50–80 mm/yr with the Pacific plate subducting at 60–100 mm/yr [8] This eastern subduction is divided into the Mariana ...
The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width.
The oceanic Philippine Sea plate subducts beneath the Eurasian plate at the Ryukyu Trench. The oceanic Pacific plate subducts under the oceanic Philippine Sea plate forming the Mariana Trench. The oceanic Philippine Sea plate is subducting under the Philippine Mobile Belt forming the Philippine Trench and the East Luzon Trench.

These smaller plates are often not shown on major plate maps, as the majority of them do not comprise significant land area. For purposes of this list, a minor plate is any plate with an area less than 20 million km 2 (7.7 million sq mi) but greater than 1 million km 2 (0.39 million sq mi).
The Izu–Bonin–Mariana (IBM) arc system is a tectonic plate convergent boundary in Micronesia.The IBM arc system extends over 2800 km south from Tokyo, Japan, to beyond Guam, and includes the Izu Islands, the Bonin Islands, and the Mariana Islands; much more of the IBM arc system is submerged below sealevel.
Oceanic trench formed along an oceanic-oceanic convergent boundary The Mariana Trench contains the deepest part of the world's oceans, and runs along an oceanic-oceanic convergent boundary. It is the result of the oceanic Pacific plate subducting beneath the oceanic Mariana plate.
This water is super-heated as the plate is carried farther downward and results in the volcanic activity which has formed the arc of Mariana Islands above this subduction region.
