Because P waves are the fastest seismic waves, they will usually be the first ones that your seismograph records. The next set of seismic waves on your seismogram will be the S waves. These are ...

Distances from the stations to the earthquake are estimated from the difference between P and S wave arrival times: You have just figured out how far your seismograph is from the epicenter and how ...

Typically, one can recognize the arrival of different wave types. The P waves (the fastest traveling waves), S waves, and Surface waves which commonly produce the highest wave amplitudes. On this ...
