Elastic-rebound theory explains an earthquake as rapid release of elastic strain accumulated while a fault resists relative motion. When slipping occurs, nearby rock moves toward a less-strained configuration and part of the released energy propagates as seismic waves.
The motivating observations for the 1906 California earthquake included displacement across the fault and deformation away from it. H. F. Reid used those relationships to connect slow loading with sudden slip. The theory concerns stored deformation and its release; it does not imply that every fault is locked uniformly or that stress measurements alone predict an earthquake's time.[ref]

The elastic-rebound theory is a scientific explanation for how energy is stored and released during the process of an earthquake. This theory, first proposed by geologist Harry Fielding Reid in the early 20th century, describes the dynamic behavior of rocks along faults. Here's a simplified breakdown of the theory: 1. **Stress Accumulation**: Tectonic forces acting on the Earth's crust create stress in rock formations.
