Not sure about the 'sudden' part, but it's called rebound.

Really its called Elastic Rebound.....

How does the elastic rebound theory explain the occurrence of earthquakes?

The sudden return of elastically deformed rock to sit original shape is called elastic rebound. Elastic rebound happens when stress on rock along a fault becomes so grat that the rock breaks or fails. This failure causes the rocks on either side of the fault to jerk past one another. During this sudden motion, large amounts of energy are released. This energy travels through rock as seismic waves. These waves cause earthquakes. The strength of an earthquake is related to the amount of energy that is released during elastic rebound.


When does an elastic rebound happen?

The sudden return of an elastically-deformed rock to its original shape when a load is removed or a stress released. This often occurs in earthquakes, as rocks either side of a slip fault, which have been stressed by friction along the fault plane, overcome static friction and rapidly rebound. Elastic rebound must not be confused with isostatic rebound, which is a much slower process in which mantle material flows under pressure into areas under the crust where large loads such as oceans or ice sheets have been removed, thus forcing the crust to rise where the load has been removed and fall elsewhere. Because of the large scales involved and extremely high viscosity of the mantle material, isostatic rebound very slow. The ground surface in the area of Scandinavia is still rebounding at a measurable rate (about 10mm per year) as a result of the melting of the Weichsel ice sheet ten thousand years ago.


What is the process by which deformed rocks return to its original shapes?

elastic change


Which term describes the ability of a solid to return to its original shape?

Elasticity describes the ability of a solid to return to its original shape after being deformed or stretched.


What is an example of elasticity?

Most materials are elastic - or behave elastically - at least a little bit. This means that when you apply forces to them to deform them, they return to their original size and shape after the deforming forces are removed.


What Stress will build until an earthquake occurs if friction along a fault is?

The mechanism for stress to be released from friction along a fault is known as elastic rebound. Vibrations occur when rocks elastically return to their original shape causing damage from the seismic waves being sent out.


What is plastic deformation?

Plastic deformation is a permanent unrecoverable deformation. When the load that caused the deformation is removed, the material will not return to it's original shape but will maintain it's newly deformed shape.


What happens to a material that undergoes stress that exceeds its strength?

If a the stress of a material exceeds the yield stress, it will not be able to return to its original length or shape once the force is removed.


What happens to someone with periodic paralysis?

A person with periodic paralysis experiences sudden onset of weakness, which gradually subsides, only to return again later.
