# What does the elastic rebound theory explain?

## What does the elastic rebound theory explain?

Elastic rebound is what happens to the crustal material on either side of a fault during an earthquake. The idea is that a fault is stuck until the strain accumulated in the rock on either side of the fault has overcome the friction making it stick.

### When was the elastic rebound theory proposed?

Overview. Elastic rebound theory is one of the central ideas to the mechanics of earthquakes and was originally proposed by Reid (1910) following the 1906 San Francisco earthquake on the San Andreas Fault.

Who proposed the elastic rebound theory for the origin of earthquakes?

Henry Fielding Reid
From an examination of the displacement of the ground surface which accompanied the 1906 earthquake, Henry Fielding Reid, Professor of Geology at Johns Hopkins University, concluded that the earthquake must have involved an “elastic rebound” of previously stored elastic stress.

What does the elastic rebound theory explain quizlet?

Elastic rebound theory. IT DESCRIBES THE BUILD UP AND RELEASE OF STRESS DURING AN EARTHQUAKE. Rocks on either side of a fault are locked in place by friction. Rocks will slowly deform over time. When the stress exceeds the strength of the rock, the rocks will fault.

## Which best explains the earthquake cycle based on elastic rebound?

Explain the earthquake cycle based on elastic rebound: Surface waves propagate more slowly. Why do surface waves arrive later than body waves during an earthquake? Which measurement is used to convey the sizes of earthquakes?

### Which of the following is part of the elastic rebound theory?

Which of the following is part of the elastic rebound theory? A rock that has been deformed by movement along a fault can suddenly snap back to its original shape.

What is elastic rebound theory and how does it apply to earthquakes quizlet?

-Rocks rupture or break. -Fault moves (slips) producing displacement. -Elastic strain recovered – energy propagates as seismic waves. Elastic Rebound Theory. The theory that continuing stress along a fault results in a buildup of elastic energy in the rocks, which is abruptly released when an earthquake occurs.

Which of the following is part of the elastic rebound theory quizlet?

## How does the elastic rebound theory explain the violent tremors that occur during earthquakes?

The elastic rebound theory suggests that if slippage along a fault is hindered such that elastic strain energy builds up in the deforming rocks on either side of the fault, when the slippage does occur, the energy released causes an earthquake.

### How does elastic rebound theory help to explain how earthquakes happen?

The elastic rebound theory is an explanation for how energy is spread during earthquakes. As rocks on oppo- site sides of a fault are subjected to force and shift, they accumulate energy and slowly deform until their inter- nal strength is exceeded.

Which theory explains how earthquakes occur?

The theory of plate tectonics revolutionized the earth sciences by explaining how the movement of geologic plates causes mountain building, volcanoes, and earthquakes.

Why is elastic rebound theory important for the study of earthquakes?

The elastic rebound theory of earthquake sources allows rough prediction of the occurrence of large shallow earthquakes. Harry F. Reid gave, for example, a crude forecast of the next great earthquake near San Francisco.
