When stress accumulates at faults, rocks undergo elastic rebound after breaking or undergoing brittle deformation.
When stress builds at faults, the rocks deform plastically and can bend and break. Eventually, the tectonic forces overcome the rock's shear strength, causing it to break or undergo brittle deformation along the fault plane. This release of strain leads to the rock returning to its undeformed state, known as elastic rebound.
