Target class: earthquake in Japan Context triple: [2011 Tōhoku earthquake and tsunami, instanceOf, earthquake in Japan]
-
A.
undersea earthquake
chosen
An undersea earthquake is a sudden release of energy along faults beneath the ocean floor, causing seismic shaking that can displace large volumes of water and potentially generate tsunamis.
-
B.
intraplate earthquake
An intraplate earthquake is a seismic event that occurs within the interior of a tectonic plate, far from plate boundaries, typically caused by the reactivation of ancient faults or stresses transmitted through the plate.
-
C.
earthquake sequence
An earthquake sequence is a series of temporally and spatially related earthquakes, including mainshocks, foreshocks, and aftershocks, that occur as a fault system adjusts to stress changes in the Earth's crust.
-
D.
earthquake monitoring center
An earthquake monitoring center is a facility that continuously collects, analyzes, and disseminates seismic data to detect earthquakes, assess their impact, and support early warning and emergency response efforts.
-
E.
earthquake intensity scale
An earthquake intensity scale is a system that categorizes and describes the observed effects and damage of an earthquake at specific locations on the Earth's surface.
- 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.
