Target class: megathrust earthquake Context triple: [2004 Indian Ocean earthquake and tsunami, instanceOf, megathrust earthquake]
-
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.
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.
-
C.
tectonic plate
A tectonic plate is a massive, rigid segment of Earth's lithosphere that moves slowly over the asthenosphere, interacting with other plates to shape the planet's surface through processes like earthquakes, volcanism, and mountain building.
-
D.
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.
-
E.
plate boundary
chosen
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.
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.
