Which crustal extension results when strike-slip faults unlock?

💡 Explanation

Extensional unlocking generates crustal thinning; normal faulting forms pull-apart basins because the released stress changes fault dynamics rather than simply stopping frictional lock alone. The strain release creates basins, therefore subsidence occurs; rather than compression which creates increased uplift around those faults.
