How this entity was disambiguated

This entity first appeared as the object of triple T7152002 — 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.

Context triple: [Takuan Group, partOfVolcanicArc, Bougainville volcanic arc]

A. New Hebrides volcanic arc
The New Hebrides volcanic arc is a chain of active and dormant volcanoes in the South Pacific formed by the subduction of the Australian Plate beneath the Pacific Plate, running through Vanuatu and surrounding islands.
B. Mariana volcanic arc
The Mariana volcanic arc is a chain of active and dormant volcanoes in the western Pacific Ocean formed by the subduction of the Pacific Plate beneath the Philippine Sea Plate.
C. Izu–Bonin Arc
The Izu–Bonin Arc is a volcanic island arc in the western Pacific Ocean formed by subduction along the boundary of the Philippine Sea Plate, stretching south from Japan’s Izu Peninsula toward the Mariana Islands.
D. Tonga–Kermadec Arc
The Tonga–Kermadec Arc is a major submarine volcanic island arc and trench system in the southwest Pacific Ocean, formed by the subduction of the Pacific Plate beneath the Indo-Australian Plate and known for its intense seismic and volcanic activity.
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.
