Dimensions. • Length. 900 mi (1,400 km) [2] Map all coordinates using OpenStreetMap. 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 ...
Ramapo Fault. The Ramapo Fault zone is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east. [1] Spanning more than 185 miles (298 km) in New York, New Jersey, and Pennsylvania, it is perhaps the best known fault zone in the Mid-Atlantic region, and some small earthquakes have been known to occur in its ...
A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. [3] [4] A fault zone is a cluster of parallel faults.
The Brevard Fault Zone is a part of a much larger system of faults at the base of the Appalachian thrust sheet [1] that played a key role in uplifting the Appalachian Mountains. The extent of its role remains uncertain because most of the fault is buried beneath Quaternary sediment. [7] Many studies of the fault come from Grandfather Mountain ...
Magnetic potential map of the Reelfoot Rift. The New Madrid Seismic Zone (NMSZ), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
The Newport–Inglewood-Rose Canyon Fault Zone. The Newport–Inglewood Fault is a right-lateral strike-slip fault [1] in Southern California.The fault extends for 47 mi (76 km) [1] (110 miles if the Rose Canyon segment is included) from Culver City southeast through Inglewood and other coastal communities to Newport Beach at which point the fault extends east-southeast into the Pacific Ocean.
USGS map showing faults that span the Pacific–North America plate boundary. The Hayward Fault Zone is a right-lateral strike-slip geologic fault zone capable of generating destructive earthquakes. The fault was first named in the Lawson Report of the 1906 San Francisco Earthquake in recognition of its involvement in the earthquake of 1868. [1]
The Puget Sound faults under the heavily populated Puget Sound region (Puget Lowland) of Washington state form a regional complex of interrelated seismogenic (earthquake-causing) geologic faults. These include (from north to south, see map) the: Devils Mountain Fault. Strawberry Point and Utsalady Point faults.
