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]
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 ...
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]
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. [2]
The East Anatolian Fault is a strike-slip fault. In those, solid rock plates are pushing up against each other across a vertical fault line, building stress until one finally slips in a horizontal ...
In the case of a fault-related event, it refers to the orientation of the fault plane that slipped, and the slip vector and is also known as a fault-plane solution. Focal mechanisms are derived from a solution of the moment tensor for the earthquake, which itself is estimated by an analysis of observed seismic waveforms. The focal mechanism can ...
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). [1]
When a strike-slip fault is offset along strike such that the resulting bend in the fault hinders easy movement, e.g. a right stepping bend on a sinistral (left-lateral) fault, this will cause local shortening or transpression. Examples include the 'Big Bend' region of the San Andreas Fault, [6] and parts of the Dead Sea Transform. [7]
