Strike-slip tectonics or wrench tectonics is a kind of tectonics that's dominated by lateral (horizontal) movements within the Earth's crust (and lithosphere).

When strike-slip fault zones develop, they sometimes type as several separate fault segments which can be offset from one another. The areas between the ends of adjoining segments are referred to as stepovers.
Within the case of a dextral fault zone, a proper-stepping offset is called an extensional stepover as movement on the 2 segments leads to extensional deformation within the zone of offset, while a left-stepping offset is called a compressional stepover. For active strike-slip techniques, earthquake ruptures may jump from one phase to another throughout the intervening stepover, if the offset is not too great. Numerical modelling has recommended that jumps of no less than eight km, or presumably more are possible.
