Target entity: Central Virginia Seismic Zone Context triple: [2011 Virginia earthquake, region, Central Virginia Seismic Zone]
-
A.
2011 Virginia earthquake
The 2011 Virginia earthquake was a rare, moderate-magnitude intraplate earthquake centered in Mineral, Virginia, that was widely felt across the U.S. East Coast and caused notable structural damage to landmarks including the Washington National Cathedral and the Washington Monument.
-
B.
Heezen Fault Zone
The Heezen Fault Zone is a major undersea geological fault system named in honor of American oceanographer Bruce C. Heezen, recognized for his pioneering work in mapping the ocean floor.
-
C.
San Jacinto Fault Zone
The San Jacinto Fault Zone is a major active strike-slip fault system in Southern California that accommodates a significant portion of the region’s tectonic motion and poses substantial earthquake hazard.
-
D.
Southern Uplands Fault
The Southern Uplands Fault is a major geological fault line in Scotland that marks the boundary between the Central Lowlands and the Southern Uplands, playing a key role in the region’s tectonic and landscape history.
-
E.
Septentrional-Oriente fault zone
The Septentrional-Oriente fault zone is a major strike-slip fault system in the northern Caribbean region that accommodates tectonic motion between the North American and Caribbean plates and is a significant source of regional earthquakes.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
