How this entity was disambiguated
This entity first appeared as the object of triple T3695697 — 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.

A.
Cocos–Caribbean plate boundary
The Cocos–Caribbean plate boundary is a tectonic interface in Central America where the oceanic Cocos Plate interacts with the Caribbean Plate, generating significant seismic and volcanic activity.
-
B.
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.
-
C.
Caribbean Plate
The Caribbean Plate is a major tectonic plate underlying Central America and the Caribbean Sea, whose interactions with surrounding plates shape the region’s earthquakes, volcanoes, and deep ocean trenches.
-
D.
Belize margin
The Belize margin is the continental shelf and slope region off the coast of Belize in the western Caribbean, characterized by extensive coral reefs and sedimentary basins along the edge of the Yucatán Basin.
-
E.
Ryukyu subduction zone
The Ryukyu subduction zone is a tectonic plate boundary south of Japan where an oceanic plate descends beneath the Okinawa Plate, generating frequent earthquakes, volcanism, and the Ryukyu island arc.

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.
