These are the waves that do the most damage to our buildings, highways, etc. ...
To apply those ideas to earthquake studies, think of the earthquake location as

Each of these waves travel at different velocities (speeds), even though they are
generated simultaneously by an earthquake at the focus (point of origin within the
crust). Since P-waves travel faster than S-waves do, the seismograph will detect
