Makran subduction zone

E593654

subduction zone tectonic plate boundary

The Makran subduction zone is a major convergent plate boundary in the northwestern Indian Ocean where the Arabian Plate is being subducted beneath the Eurasian Plate, capable of generating large earthquakes and tsunamis.

How this entity was disambiguated

This entity first appeared as the object of triple T6451072 — 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: Makran subduction zone
Context triple: [Makran coast, hasGeologicalFeature, Makran subduction zone]

A. 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.
B. 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.
C. 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.
D. Makran coast
The Makran coast is a long, arid coastal region along the northern Arabian Sea spanning southeastern Iran and southwestern Pakistan, known for its tectonic activity, rugged terrain, and strategic maritime location.
E. Nankai megathrust
The Nankai megathrust is a major subduction-zone fault off southwestern Japan that has produced numerous powerful earthquakes and tsunamis and poses a significant seismic hazard to the region.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
