Northeastern Japan Arc

Target entity: Northeastern Japan Arc
Context triple: [Mount Akagi, volcanicArc, Northeastern Japan Arc]

• A. 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.
• B. Aleutian Arc
  The Aleutian Arc is a major volcanic island chain and subduction zone stretching from Alaska toward Russia, forming part of the tectonically active northern boundary of the Pacific Ocean.
• C. Kyushu–Palau Ridge system
  The Kyushu–Palau Ridge system is a major underwater volcanic island arc and tectonic ridge in the Philippine Sea, formed by subduction-related processes along the western Pacific margin.
• D. Japan Trench
  The Japan Trench is a deep oceanic trench off northeastern Japan where the Pacific Plate subducts beneath the Okhotsk Plate, forming part of the Pacific Ring of Fire and generating powerful earthquakes and tsunamis.
• E. Nankai Trough
  The Nankai Trough is a major submarine trench off the coast of southwestern Japan, known as a highly active subduction zone capable of generating powerful megathrust earthquakes and tsunamis.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
