The Little River Fault (see the QFFDB, Fault 556) is representative of an extensive zone of faults along the north side of the Olympic Peninsula and in the Strait of Juan de Fuca (likely connected with the fault systems at the south end of Vancouver Island, see fault database map), but these lie west of the crustal blocks that underlie the ...
The Cascadia subduction zone is a 1,000 km (620 mi) long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino in northern California. It separates the Juan de Fuca and North America plates. New Juan de Fuca plate is created offshore along the Juan de Fuca Ridge. [8] [9]

To map the subduction zone, researchers at sea performed active source seismic imaging, a technique that sends sound to the ocean floor and then processes the echoes that return. The method is ...
The northern boundary with the North American plate is a transform or strike-slip boundary that runs from the border area of Belize, Guatemala (Motagua Fault), and Honduras in Central America, eastward through the Cayman trough along the Swan Islands Transform Fault before joining the southern boundary of the Gonâve microplate.
The section of the fault zone directly under "Seattle" corresponds to the red line in the photo at the top. (DGER [9]) One model of the Seattle Uplift: Cross-section (south to north) along the east side of central Puget Sound, looking west. TB = Tacoma Basin EPZ = East Passage Zone (Maury Island), SFZ = Seattle Fault Zone (Alki Point).
The Atlantic Seaboard Fall Line, or Fall Zone, is a 900-mile (1,400 km) escarpment where the Piedmont and Atlantic coastal plain meet in the eastern United States. [2] Much of the Atlantic Seaboard fall line passes through areas where no evidence of faulting is present.
Situated on Bathurst Island is the Southeast Bathurst Fault Zone, a north–south trending system of normal faults that form a graben-like structure. It originally formed during the Boreal Rifting Episode, but was reactivated during a period of regional uplift and compression brought on by the Eurekan Rifting Episode. [ 22 ]
