The type of force found in a strike slip fault is lateral force.

The type of stress force that produces a strike-slip fault is transform stress. This stress occurs when two tectonic plates slide past each other horizontally, causing displacement along a fault line. Strike-slip faults are often associated with transform plate boundaries, such as the San Andreas Fault in California.
The bending and buckling of rocks under great force produces a fold.
Higher frictional resistance along a fault can inhibit the fault from slipping smoothly, causing stress to accumulate over time. When this stress is eventually released as an earthquake, the force released can be higher if the resistance was greater. Conversely, lower frictional resistance can allow the fault to slip more easily, potentially leading to a lower force released during an earthquake.
Tensional stress from divergent plate boundaries causes a normal fault to form. This stress pulls rocks apart along a fault line, causing the hanging wall to drop relative to the footwall.
Strike-slip faults are caused by horizontal shear stress along the fault plane, which results in horizontal movement of the rocks on either side of the fault. The movement can be either left-lateral (sinistral) or right-lateral (dextral), depending on the direction of the shear stress.
The force that causes rocks on either side of a fault to slide past each other is the built-up stress along the fault line, which is released as the two sides move in opposite directions. This stress can accumulate due to tectonic plate movements, leading to the sudden release of energy in the form of an earthquake.
