An idealized strike-slip fault runs in a straight line with a vertical dip and has only horizontal motion, thus there is no change in topography due to motion of the fault. In reality, as strike-slip faults become large and developed, their behavior changes and becomes more complex. A long strike-slip fault follows a staircase-like trajectory ...
Most researchers consider the fault active or a "reactivated strike-slip fault within the continental crust" that is accumulating tectonic strain. [4] [6] [7] Some researchers say the observed seismic activity of the last 300 years does not support a theory of re-activation. According to Roger Musson, the fault does not show any signs of ...
A fault bend, or fault stepover, forms when individual segments of the fault overlap and link together. The type of structures which form along the strike-slip fault depend on the sense of slip relative to the sense of stepping. When a sinistral fault steps to the right or a dextral fault steps to the left, a restraining bend is formed. [2]
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]
Magmatism along strike-slip faults is the process of rock melting, magma ascent and emplacement, associated with the tectonics and geometry of various strike-slip settings, most commonly occurring along transform boundaries at mid-ocean ridge spreading centres [1] and at strike-slip systems parallel to oblique subduction zones.

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).

Oblique subduction model with the development of forearc sliver and margin parallel strike slip fault. Forearc sliver is a microplate bounded by the oceanic trench and strike slip fault. [14] Trench parallel strike slip fault develops when the forearc sliver moves away from stable continent. [14] Adapted from Haq and Davis, 2010. [14]
