Locations where the bend is oriented such that blocks on opposite sides of the fault are squeezed together are restraining bends, whereas locations where the bend is oriented such that blocks on opposite sides of the fault pull away from each other are releasing bends.
Where movement across a segment of a strike-slip fault results in some compression, we say that transpression is occurring across the fault, and where movement results in some extension, we say that transtension is occurring across the fault.
