Indonesia–Australia plate boundary zone

E745512

geological region tectonic plate boundary zone

The Indonesia–Australia plate boundary zone is a complex tectonic region where the Indo-Australian Plate interacts with the Eurasian and Pacific-related plates, producing intense seismicity, subduction, and mountain-building across eastern Indonesia and northern Australia.

How this entity was disambiguated

This entity first appeared as the object of triple T8616121 — 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: Indonesia–Australia plate boundary zone
Context triple: [Seram Trough, isPartOf, Indonesia–Australia plate boundary zone]

A. 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.
B. Sunda Plate
The Sunda Plate is a minor tectonic plate in Southeast Asia that underlies much of Indonesia and surrounding regions, interacting with several neighboring plates and contributing to the area's high seismic and volcanic activity.
C. Banda Sea Plate
The Banda Sea Plate is a small tectonic plate in eastern Indonesia involved in complex interactions and subduction with surrounding microplates and major plates in the region.
D. Solomon Sea Plate
The Solomon Sea Plate is a small, active oceanic tectonic plate in the southwestern Pacific, located north of Papua New Guinea and associated with intense subduction and volcanism.
E. Sunda Arc
The Sunda Arc is a major volcanic island arc in Indonesia formed by the subduction of the Indo-Australian Plate beneath the Eurasian Plate, hosting numerous active volcanoes across Sumatra, Java, and the Lesser Sunda Islands.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
