Can you briefly describe the elastic rebound theory of earthquake?

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.

∙ 11y agoWhen the rocks break or move, a fault is produced. As the rocks break energy is released in the form of waves this causes the crust of the Earth to actually shake This explanation of how earthquakes occur is known as the elastic rebound theory
Wiki User
∙ 9y agoThe Elastic rebound theory is the explanation for how energy is spread during earthquakes. As rocks are forced to shift by faults, they accumulate energy until they are forced to slowly deform.

the elastic rebound theory
What scientific discoveries were made from the 1906 San Francisco Earthquake?
The elastic-rebound theory was found from the 1906 San Francisco 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.
What is the definition for the word earthquake?
An Earthquake is a series of vibrations induced in the earth's crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating.
