'''Elastic rebound theory''', formulated by [[Harry Fielding Reid]] in 1910 after studying the 1906 San Francisco earthquake, is the foundational mechanical model of earthquake generation. The theory holds that earthquakes result from the sudden release of accumulated elastic strain energy in rocks adjacent to a fault. As [[Tectonic loading|tectonic loading]] drives crustal blocks past one another, the rocks on either side of the fault deform elastically — bending and stretching like a spring — while friction along the fault interface prevents slip. When the accumulated stress exceeds the frictional strength of the fault, the rocks rupture and snap back to their undeformed shape, releasing the stored energy as seismic waves and [[Coseismic slip|cosesmic slip]] along the fault surface.

The theory transformed seismology by providing a physical mechanism for earthquakes that was independent of any particular observational technique. It connected the measurable ground displacement after an earthquake to the total [[Seismic moment|seismic moment]] and thus to the [[Moment magnitude scale|moment magnitude]] of the event. But the theory's simplicity is also its limitation: it assumes the crust behaves as a perfectly elastic solid, ignoring the role of fluid pressure, plastic deformation, and the granular dynamics of the fault zone itself. Modern seismology treats elastic rebound not as the complete explanation but as the zeroth-order approximation against which more complex models — involving [[Fault mechanics|fault mechanics]], rate-and-state friction, and damage mechanics — are measured.
