Izu–Bonin–Mariana Trench system

E278483

convergent plate boundary oceanic trench system subduction zone

The Izu–Bonin–Mariana Trench system is a major convergent plate boundary in the western Pacific Ocean, forming one of the world’s deepest and most extensive oceanic trench complexes associated with intense subduction and seismic activity.

How this entity was disambiguated

This entity first appeared as the object of triple T2256074 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Izu–Bonin–Mariana Trench system
Context triple: [Izu–Ogasawara Trench, isSegmentOf, Izu–Bonin–Mariana Trench system]

A. Aleutian Trench
The Aleutian Trench is a deep oceanic trench in the North Pacific where the Pacific Plate subducts beneath the North American Plate, forming part of a major seismically active subduction zone.
B. New Britain Trench
The New Britain Trench is a deep oceanic trench near Papua New Guinea formed by the subduction of the Solomon Sea Plate beneath the South Bismarck Plate, making it one of the major deep-sea features of the southwestern Pacific.
C. Sunda Trench
The Sunda Trench is a deep oceanic trench in the eastern Indian Ocean off the coasts of Sumatra and Java, formed by the subduction of the Indo-Australian Plate beneath the Eurasian Plate.
D. Kuril Trench
The Kuril Trench is a deep oceanic trench in the northwest Pacific Ocean off the Kuril Islands, formed by the subduction of the Pacific Plate beneath the Okhotsk Plate and known for its intense seismic and volcanic activity.
E. New Guinea Trench
The New Guinea Trench is a deep oceanic trench in the western Pacific Ocean formed by the subduction of the Caroline Plate beneath the New Guinea region.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
