How this entity was disambiguated
This entity first appeared as the object of triple T401910 — 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: Andean subduction system Context triple: [Nazca Plate, partOfSystem, Andean subduction system]
-
A.
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.
-
B.
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.
-
C.
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.

D.
Southern Uplands accretionary prism
The Southern Uplands accretionary prism is a large, deformed wedge of sedimentary rocks in southern Scotland formed by the off-scraping and stacking of oceanic sediments during ancient subduction along the Iapetus Ocean.

E.
Cascadia Subduction Zone
The Cascadia Subduction Zone is a major convergent plate boundary off the Pacific Northwest coast of North America, capable of generating powerful megathrust earthquakes and tsunamis.
- F. None of above. chosen

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Andean subduction system Description of subject: The Andean subduction system is a major tectonic convergent margin along western South America where an oceanic plate descends beneath the continent, driving Andean mountain building, volcanism, and seismic activity.
