How this entity was disambiguated
This entity first appeared as the object of triple T2468234 — 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.
Septentrional-Oriente fault zone
The Septentrional-Oriente fault zone is a major strike-slip fault system in the northern Caribbean region that accommodates tectonic motion between the North American and Caribbean plates and is a significant source of regional earthquakes.

B.
Rivera Transform Fault Zone
The Rivera Transform Fault Zone is a major tectonic boundary in the eastern Pacific Ocean that accommodates lateral motion between the Rivera Plate and adjacent plates near the Middle America Trench.
-
C.
Garlock Fault
The Garlock Fault is a major left-lateral strike-slip fault in southern California that forms the northern boundary of the Mojave Desert and plays a key role in the region’s complex tectonic deformation.
-
D.
Liquiñe-Ofqui Fault Zone
The Liquiñe-Ofqui Fault Zone is a major strike-slip fault system in southern Chile that controls much of the region’s tectonic activity, volcanism, and seismicity along the Andean margin.
-
E.
Fairweather Fault
The Fairweather Fault is a major strike-slip fault in southeastern Alaska that forms part of the Pacific–North American plate boundary and is associated with significant seismic activity.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

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: Romanche transform fault Description of subject: The Romanche transform fault is a major east–west striking fracture zone and transform fault in the equatorial Atlantic Ocean that offsets the Mid-Atlantic Ridge and hosts one of the deepest points in the Atlantic.
