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.
