A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal. [1] It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone . [ 2 ]
Globally most fault zones are located on divergent plate boundaries on oceanic crust. This means that they are located around mid-ocean ridges and trend perpendicular to them. The term fracture zone is used almost exclusively for features on oceanic crust ; similar structures on continental crust are instead termed transform or strike slip faults .
The Motagua Fault, which crosses through Guatemala, is a transform boundary between the southern edge of the North American plate and the northern edge of the Caribbean plate. New Zealand's Alpine Fault is another active transform boundary. The Dead Sea Transform (DST) fault which runs through the Jordan River Valley in the Middle East.
As the plates on either side of an offset mid-ocean ridge move, a transform fault forms at the offset between the two ridges. [2] Fracture zones and the transform faults that form them are separate but related features. Transform faults are plate boundaries, meaning that on either side of the fault is a different plate.
San Andreas Fault System (Banning fault, Mission Creek fault, South Pass fault, San Jacinto fault, Elsinore fault) 1300: California, United States: Dextral strike-slip: Active: 1906 San Francisco (M7.7 to 8.25), 1989 Loma Prieta (M6.9) San Ramón Fault: Chile: Thrust fault: Sawtooth Fault: Idaho, United States: Normal fault: Seattle Fault ...
In some usages, the name Owen Transform Fault is used to denote the short section between the end of the Aden-Sheba ridge and the Carlsberg Ridge. [3] Additionally, this area has been called the Aden–Owen–Carlsberg triple junction , although the Carlsberg Ridge is offset 330 km (210 mi) from the point where the Owen fracture zone/fault ...
The transform fault of the southern fracture zone displaces the Mid-Atlantic Ridge, coming from the Azores triple junction, to the west over a distance of 120 km (75 mi). At longitude 31.75W a south to north seismically active rift valley with a length of 40 km (25 mi) connects the western end of the southern transform to the eastern end of the ...
Pacific Ocean depth map showing the Heezen fault and the Tharp fault as #17. The Eltanin fault system (Eltanin fracture zone) is a series of six or seven dextral transform faults that offset the Pacific-Antarctic Ridge, a spreading zone between the Pacific plate and the Antarctic plate. This is extending by up to 7.93 cm/year (3.12 in/year). [1]
