The elastic rebound theory was developed by Harry Fielding Reid, an American geophysicist who was studying the 1906 San Francisco earthquake.
He observed that points on the Earth's surface distant from the San Andreas fault had gradually moved prior to the earthquake whereas points on the surface directly on and around the fault had not.
During the earthquake the points next to the fault zone which had originally been static had suddenly shifted to match up with the points at a greater distance from the locked fault zone.
He concluded that this was due to the accumulation of elastic strain within the Earth's crust around the fault zone and that when the stress that caused this strain exceeded the strength of the rock mass or fault zone in the crust it suddenly ruptured. This caused the stored energy (termed elastic potential energy) to be released in one instant, causing an earthquake, and also meant that the rock mass around the fault zone that had originally been locked in position, snapped or rebounded to match the position of the rock mass at a greater distance from the fault. As such he coined the term "elastic rebound" to describe this phenomenon.

What are the 4 stages of elastic rebound hypothesis?
The four stages of the elastic rebound hypothesis are: (1) rocks on either side of a fault are deformed by stress, (2) stress overcomes friction causing rocks to break and shift, (3) stored elastic energy is released as the rocks rebound to their original shape, and (4) seismic waves are generated causing an earthquake.
The hypothesis that explains the release of energy during an earthquake is called the?
The hypothesis that explains the release of energy during an earthquake is called the elastic rebound theory. This theory states that rocks on either side of a fault are deformed by tectonic stresses until they reach a breaking point. Once this breaking point is exceeded, energy is released in the form of seismic waves, causing an earthquake.
Sudden return of elastically deformed rock to its unformed shape?
This phenomenon is known as elastic rebound and it occurs when a rock that has been subject to stress suddenly releases that stress, causing it to return to its original shape. This can happen during an earthquake when built-up strain in the rock is released, leading to rapid deformation and rebound.
The elastic rebound theory for the origin of earthquakes was first proposed by?
The elastic rebound theory for the origin of earthquakes was first proposed by American geologist Harry Fielding Reid in 1910. This theory states that tectonic stress builds up along faults until it exceeds the strength of the rocks, causing them to suddenly break and release energy in the form of an earthquake.

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.

The hypothesis that explains the release of energy during an earthquake is called the elastic rebound theory. According to this theory, stress builds up along a fault line until it exceeds the strength of the rocks, causing them to suddenly break and release accumulated energy in the form of seismic waves.
