Target entity: Nankai Trough Context triple: [Hyuga-nada segment, associatedWithPlateBoundary, Nankai Trough]
-
A.
Nankai Trough
chosen
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.
-
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.
Okinawa Trough
The Okinawa Trough is a back-arc basin in the East China Sea, located between the Ryukyu Islands and mainland Asia, known for its active tectonics and hydrothermal activity.
-
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.
-
