Here's why:
* Stress and Strain: The Earth's crust is constantly under stress from tectonic plate movement. This stress builds up over time, causing the rocks to deform and strain.
* Slippage: When the stress exceeds the strength of the rocks, they suddenly slip past each other. This sudden release of energy creates seismic waves that travel through the Earth.
* Seismic Waves: These waves cause the ground to shake, resulting in an earthquake. The intensity and duration of the earthquake depend on the amount of energy released during the slippage.
Therefore, the immediate result of a sudden slippage of rocks within Earth's crust is the release of stored energy in the form of seismic waves, resulting in an earthquake.
