The fastest waves shaking the ground like an accordeon (contraction and expansion) are the P waves. They have a global velocity of 5.5km/s in the crust while S waves moves at velocities around 3.2 km/s in the crust. Then you have surface waves (rayleigh and Love) which propagates only in the crust at velocities smaller than the S waves velocity.

A compression wave(as opposed to a transverse wave, which causes a material to wave up and down when it passes through).

What order do seismic waves come in?

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.
