Types of Fault Lines
Plate boundaries can be faults and faults can be plate boundaries. Not all faults are plate boundaries. If rock on both sides of the fault is part of the same plate, i.e. rotating about essentially the same pole, the fault is not a plate boundary.
Coordinates The Cascadia subduction zone (also referred to as the Cascadia fault) is a convergent plate boundary that stretches from northern Vancouver Island to Northern California.
The Denali Fault is located in Alaska's Denali National Park and to the east. This National Park includes part of a massive mountain range more than 600 miles long. Along the Denali Fault, lateral and vertical offset movement is taking place (as evidenced by many earthquakes in the region).
The Hayward Fault Zone is a geologic fault zone capable of generating destructive earthquakes. This fault is about 74 mi (119 km) long, situated mainly along the western base of the hills on the east side of San Francisco Bay.
The New Madrid Seismic Zone (NMSZ) is the most active seismic area in the United States, east of the Rocky Mountains. The NMSZ is located in southeastern Missouri, northeastern Arkansas, western Tennessee, western Kentucky and southern Illinois.
The Ramapo Fault zone is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east. 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 vicinity.
Transcurrent fault: A transverse fault in which crustal blocks move horizontally in the direction of the fault; also known as a strike-slip fault because movement at a transcurrent fault occurs along the strike of a fault.
A transform fault or transform boundary is a plate boundary where the motion is predominantly horizontal. It ends abruptly and is connected to another transform, a spreading ridge, or a subduction zone.
