This list covers all faults and fault-systems that are either geologically important [clarification needed] or connected to prominent seismic activity. [clarification needed] It is not intended to list every notable fault, but only major fault zones.
An active fault is a fault that is likely to become the source of another earthquake sometime in the future. Geologists commonly consider faults to be active if there has been movement observed or evidence of seismic activity during the last 10,000 years. [1] Active faulting is considered to be a geologic hazard – one related to earthquakes as
Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. [1] Energy release associated with rapid movement on active faults is the cause of most earthquakes.
In the crowded field of active or potentially active fault zones that have been discovered in the lower Snoqualmie Valley, the Cherry Creek fault zone is particularly notable because east of Duvall [81] it passes through a hotspot of active seismicity, including the 1996 M L 5.3 Duvall earthquake. [82]
The San Jacinto Fault Zone and the San Andreas Fault (SAF) accommodate up to 80% of the slip rate between the North American and Pacific plates.The extreme southern portion of the SAF has experienced two moderate events in historical times, while the SJFZ is one of California's most active fault zones and has repeatedly produced both moderate and large events.
The Almanor Fault Zone contains both strike-slip faults, where the earth moves from side to side; and “normal” faults, “where there’s extension in the crust, so things are being pulled ...
“Turkey is located in one of the most seismically active regions on Earth,” Bozdag said. ... performing a counterclockwise rotational motion using the two major faults zones: North Anatolian ...
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 vicinity.
