Target class: subduction-zone megathrust fault Context triple: [Nankai megathrust, instanceOf, subduction-zone megathrust fault]
-
A.
subduction zone
A subduction zone is a tectonic boundary where one lithospheric plate sinks beneath another into the mantle, generating intense seismic activity, volcanism, and mountain building.
-
B.
seismotectonic segment
A seismotectonic segment is a distinct portion of a fault or plate boundary characterized by relatively uniform geological and tectonic properties that control its earthquake behavior and rupture patterns.
-
C.
strike-slip fault
A strike-slip fault is a fracture in the Earth's crust where blocks of rock slide horizontally past each other, primarily due to shear stress.
-
D.
oceanic trench
An oceanic trench is a long, narrow, and extremely deep depression in the ocean floor, typically formed at convergent plate boundaries where one tectonic plate subducts beneath another.
-
E.
plate boundary
A plate boundary is the region where two or more tectonic plates meet and interact, often causing earthquakes, volcanic activity, and mountain building.
- F. None of above. chosen
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
