Understanding Elastic Rebound in Rocks

What is Elastic Rebound?

Elastic rebound is a term used to describe the phenomenon when a rock snaps and then bounces back to its original shape. This process is commonly observed in rocks that have been subjected to stress, such as during an earthquake.

How Does Elastic Rebound Work?

When a rock is compressed or bent due to tectonic forces, it stores elastic energy within its structure. Once the stress on the rock exceeds its elastic limit, the rock snaps and releases the stored energy, causing it to bounce back to its original shape. This sudden release of energy is what generates seismic waves during an earthquake.

Importance of Elastic Rebound

Understanding elastic rebound is essential for studying earthquakes and predicting their potential impact. By analyzing the behavior of rocks under stress and how they rebound elastically, scientists can better assess the likelihood and magnitude of future earthquakes in seismically active regions.
