How do rock fractures cause vibrations?

Earth seismic waves creates vibrations and makes the plate move, it leads to splitting and breaking of the rocks.

Explanation:

First, when the crust is broken due to forces of folding and faulting processes, the stress extends towards the rocks and which if prolonged can lead to snapping and breaking of the rocks in their new position. This process leads to vibration due to the release of the seismic waves. The fault created a fracture in the rocks and thus energy is released from within.
