the tendency for the deformed rock along a fault to spring back after an earthquake
elastically
Elastic rebound. This phenomenon occurs when stress builds up in a rock mass and causes it to deform, then suddenly release that stress by rebounding to its original shape. Elastic rebound is often associated with earthquakes and fault movements.
Earthquakes will happen.

Earthquakes will happen.
Inelastic things can not be stretched or do not rebound while elastic things will stretch, bounce, rebound, etc..

the rocks are deformed they break relasing the stored energy
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.
