In what order do seismic waves arrive at a seismograph station?

P waves, S waves, L waves and Rayleigh Waves.

Explanation:

The 4 types of seismic waves which are S-waves, P-waves, L-waves and Rayleigh Waves arrive at a seismograph station in this order:

The first waves that arrive are the P-waves which are the fastest waves of all 4 of them. The second waves that arrive at the station are S-waves followed by L waves and Rayleigh waves.

I hope this answer helps.

no simpler subs form complex ones. synthesise = make
