Target entity: Japan Trench area
Context triple: [Higashimatsushima, isLocatedOnTectonicBoundaryRegion, Japan Trench area]
  • A. Japan Trench chosen
    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.
  • B. Sagami Trough
    Sagami Trough is a deep submarine trench off central Japan that marks a major tectonic plate boundary and is associated with significant seismic and tsunami activity.
  • C. 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.
  • D. 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.
  • E. Izu–Ogasawara Trench
