Strike-slip tectonics or wrench tectonics is a type of tectonics that is dominated by lateral (horizontal) movements within the Earth's crust (and lithosphere).Where a zone of strike-slip tectonics forms the boundary between two tectonic plates, this is known as a transform or conservative plate boundary.
Strike-slip faults with left-lateral motion are also known as sinistral faults and those with right-lateral motion as dextral faults. [18] Each is defined by the direction of movement of the ground as would be seen by an observer on the opposite side of the fault. A special class of strike-slip fault is the transform fault when it forms a plate ...
Lateral strike-slip faults. Strike-slip faults occur when the blocks slide against each other laterally, parallel to the plane. The direction of the slip can be observed from either side of the fault, with the far block moving to the left indicating a left lateral slip, and the converse indicating a right lateral slip. See animation here [5]
Strike-slip faults are commonly almost vertically inclined faults, where the main displacement and slip is in the horizontal direction, parallel to the strike of the fault. Depending on the movement of the fault blocks relative to the fault plane, strike-slip faults can be classified as either sinistral (left-lateral displacement) or dextral ...
Diagram of fault geometry (in map view) that leads to transtension at the bend or step-over. Releasing bends are transtensional structures that form where the orientation of a strike-slip fault becomes oblique to the regional slip vector causing local extension (such as a right stepping bend on a right-lateral fault).

The fault zone responsible for Thursday's 7.0 magnitude earthquake off the coast of California is not known to produce large tsunamis, but due to the size of the event, NOAA’s Tsunami Warning ...
A thrust fault is a type of reverse fault, in which the rock above the fault is displaced upwards relative to the rock below the fault. This distinguishes reverse faults from normal faults , where the rock above the fault is displaced downwards, or strike-slip faults , where the rock on one side of the fault is displaced horizontally with ...
Strike-slip faults are associated with dominantly horizontal movement, leading to relatively simple linear zones of surface rupture where the fault is a simple planar structure. However, many strike-slip faults are formed of overlapping segments, leading to complex zones of normal or reverse faulting depending on the nature of the overlap.
