What generates seismic waves in a fault, resulting in an earthquake

sudden release of stored elastic energy in rocks

Explanation:

Every Earth rock stores elastic energy, when an earthquake occurs, this elastic energy stored in Earth rocks is released. This energy sends out vibrations known as  seismic waves in faults,  that travel in all directions throughout the Earth.

This seismic waves consists of surface waves and body waves (Primary waves and secondary waves).

The  focus or hypocenter is the exact location within the earth crust were seismic waves are generated by the sudden release of stored elastic energy.

explanation:

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
