Diagram showing a transform fault with two plates moving in opposite directions Transform fault (the red lines) 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 ...
An interplate earthquake event occurs when the accumulated stress at a tectonic plate boundary are released via brittle failure and displacement along the fault. There are three types of plate boundaries to consider in the context of interplate earthquake events: [4] Transform fault: Where two boundaries slide laterally relative to each other.
At the triple junction each of the three boundaries will be one of three types – a ridge (R), trench (T) or transform fault (F) – and triple junctions can be described according to the types of plate margin that meet at them (e.g. fault–fault–trench, ridge–ridge–ridge, or abbreviated F-F-T, R-R-R).
A leaky transform fault is a transform fault with volcanic activity along a significant portion of its length producing new crust. [1] In addition to the regular strike-slip motion observed at transform boundaries, an oblique extensional component is present, resulting in motion of the plates that is not parallel to the plate boundary.
The Ungava Fault Zone, also called the Ungava Transform Fault Zone and the Ungava Fault Complex, is a major strike-slip fault system in Davis Strait between Baffin Island and Greenland. [1] Its faults are oriented northeast–southwest and were tectonically active in the Paleogene , during which time the fault zone formed a boundary between the ...

The likelihood of fault reactivation depends on the dip of the existing fault plane. Lower angle faults are more favourable as the resolved shear stress on the plane is higher. When a listric fault , which increases in dip upwards, reactivates the uppermost part of the fault may be too steep and new reverse faults typically develop in the ...
The Azores–Gibraltar transform fault (AGFZ), also called a fault zone and a fracture zone, is a major seismic zone in the eastern Atlantic Ocean between the Azores and the Strait of Gibraltar. It is the product of the complex interaction between the African , Eurasian , and Iberian plates. [ 1 ]
