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 ...
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 ...
45°N124°W / 45°N 124°W The Cascadia subduction zone is a 960 km (600 mi) fault at a convergent plate boundary, about 100–200 km (70–100 mi) off the Pacific coast, that stretches from northern Vancouver Island in Canada to Northern California in the United States. It is capable of producing 9.0+ magnitude earthquakes and tsunamis ...
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 Queen Charlotte Fault is an active transform fault that marks the boundary of the North American plate and the Pacific plate. [1][2] It is Canada 's right-lateral strike-slip equivalent to the San Andreas Fault to the south in California. [3] The Queen Charlotte Fault forms a triple junction south with the Cascadia subduction zone and the ...
The Ramapo Fault System is the longest in the northeastern U.S., stretching from Pennsylvania to southeastern New York. Map of the Ramapo Fault System: Earthquake epicenter at Lebanon, NJ ...
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 ...
North America was slowly pulled westward away from the rift zone. The thick continental crust that made up the new east coast collapsed into a series of down-dropped fault blocks that roughly parallel today's coastline. At first, the hot, faulted edge of the continent was high and buoyant relative to the new ocean basin.
