Aleutian subduction system

E257335

convergent plate boundary subduction zone tectonic plate boundary

The Aleutian subduction system is a major tectonic plate boundary where the Pacific Plate is forced beneath the North American Plate, forming the Aleutian Trench and associated volcanic island arc in the North Pacific.

How this entity was disambiguated

This entity first appeared as the object of triple T2328710 — 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.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Aleutian subduction system
Context triple: [Kuril–Kamchatka subduction system, adjacentTo, Aleutian subduction system]

A. Kuril–Kamchatka subduction system
The Kuril–Kamchatka subduction system is a major convergent plate boundary in the northwest Pacific where the Pacific Plate subducts beneath the Okhotsk Plate, generating intense seismic activity and extensive volcanism along the Kuril Islands and Kamchatka Peninsula.
B. Sunda subduction system
The Sunda subduction system is a major convergent plate boundary in Southeast Asia where the Indo-Australian Plate is being subducted beneath the Eurasian/Sunda Plate, generating intense seismic and volcanic activity along Indonesia’s island arcs.
C. Tonga-Kermadec subduction system
The Tonga-Kermadec subduction system is a major convergent plate boundary in the southwest Pacific where the Pacific Plate descends beneath the Indo-Australian Plate, producing one of the world’s deepest ocean trenches and most active seismic and volcanic regions.
D. Mariana subduction zone
The Mariana subduction zone is a deep oceanic trench system in the western Pacific where the Pacific Plate is forced beneath the smaller Mariana Plate, creating one of the world's deepest and most active tectonic boundaries.
E. Sumatra subduction zone
The Sumatra subduction zone is a major convergent plate boundary off the western coast of Sumatra where intense seismic and volcanic activity occurs, including some of the world’s largest recorded earthquakes and tsunamis.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
