Primary waves
Rayleigh waves which are a type of seismic surface wave.
P waves - compress and expand the ground like a Accordion S waves - vibrate from side to side as well as up and down Surface waves - make the ground roll like ocean waves The Earthquake is produced by each of the three types of seismic waves.

Rayleigh waves (which are a type of surface wave) produce the largest amplitude and so most severe ground movements during earthquakes.Surface waves produce the most severe ground movements. They produce movements similar to waves in the water, where the water's particles move in a pattern that is almost circular. Surface waves can make the ground roll like ocean waves or shake buildings from side to side. They move more slowly then P waves or S waves.

Mechanical waves, like sound waves, seismic waves, and ocean waves, do. Electromagnetic waves, like radio, light, and X-rays, do not.
First P waves, seismic waves that compress and expand the ground like an accordion. Then S waves, seismic waves that vibrate from side to side as well as up and down. And finally Surface waves, they move more slowly than P waves and S waves. But they can produce severe ground movements.
It is possible to have a seismic wave without having an earthquake. Any wave moving through the ground is a seismic wave, and all earthquakes are seismic waves. But seismic waves can be created by volcanic action, landslides, meteor strikes or the like. Though all earthquakes are seismic waves, not all seismic waves are earthquakes.
The Surface Of The Earth (The Ground) and though the centre of the Earth. Hey are pressure waves like sound waves.
