In geology, the elastic-rebound theory is an explanation for how energy is released during an earthquake. As the Earth's crust deforms, the rocks which span the opposing sides of a fault are subjected to shear stress. Slowly they deform, until their internal rigidity is exceeded.
Elastic recoil means the rebound of the lungs after having been stretched by inhalation, [1] or rather, the ease with which the lung rebounds. With inhalation, the intrapleural pressure (the pressure within the pleural cavity) of the lungs decreases. Relaxing the diaphragm during expiration allows the lungs to recoil and regain the intrapleural ...
Earthquake-cycle theory combines the stress-accumulation hypothesis and elastic-rebound theory. [1] A complete earthquake cycle can be divided into interseismic, preseismic, coseismic and postseismic periods. [1] During the interseismic period, stress accumulates on a locked fault due to plate motion. [2]
The tunica externa is made from collagen and elastic fibers in a loose connective tissue. [1] [2] This is secreted by fibroblasts. [1]This is normally the thickest tunic in veins and may be thicker than the tunica media in some larger arteries.
This energy is released as a combination of radiated elastic strain seismic waves, [9] frictional heating of the fault surface, and cracking of the rock, thus causing an earthquake. This process of gradual build-up of strain and stress punctuated by occasional sudden earthquake failure is referred to as the elastic-rebound theory. It is ...
The central uplift is not the result of elastic rebound, which is a process in which a material with elastic strength attempts to return to its original geometry; rather the uplift is a process in which a material with little or no strength attempts to return to a state of gravitational equilibrium.

According to the elastic rebound theory of Reid (1910), eventually the deformation (strain) becomes great enough that something breaks, usually at an existing fault. Slippage along the break (an earthquake) allows the rock on each side to rebound to a less deformed state. In the process, energy is released in various forms, including seismic ...
