-
A.
Kuril–Kamchatka subduction system
chosen
The Kuril–Kamchatka subduction system is a major convergent plate boundary in the northwest Pacific where the Pacific Plate subducts beneath the Okhotsk Plate, generating intense seismic activity and extensive volcanism along the Kuril Islands and Kamchatka Peninsula.
-
B.
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.
-
C.
Mariana subduction zone
The Mariana subduction zone is a deep oceanic trench system in the western Pacific where the Pacific Plate is forced beneath the smaller Mariana Plate, creating one of the world's deepest and most active tectonic boundaries.
-
D.
Kamchatka Trench
The Kamchatka Trench is a deep oceanic trench in the northwest Pacific Ocean, formed by the subduction of the Pacific Plate beneath the Kamchatka Peninsula and known for its great depths and intense seismic activity.
-
E.
Nankai megathrust
The Nankai megathrust is a major subduction-zone fault off southwestern Japan that has produced numerous powerful earthquakes and tsunamis and poses a significant seismic hazard to the region.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
