S-waves travelling through the Earth will bounce or reflect off material interfaces inside the Earth, arriving at different times depending on where they interact with these interfaces.
One type of S-wave reflects from Earth's surface halfway between an earthquake and a seismometer.

Then five minutes of S-waves and feeling sort of seasick," he added.
The S-waves are secondary and have a more up-and-down motion.
and the structure of the upper mantle, Geophys.
Alfaro shows his results on the application of a heuristic method for estimation of velocity structure for S-waves
and compares his findings with existing PS-logging data.
An alarm would sound with the first P-waves, a few crucial moments before ground-shaking S-waves
Therefore, we can represent the collision in terms of two s-waves
, one p-wave, and two d-waves.
He explained how progress towards the critical point where a stressed rock mass fractures and causes an earthquake can be monitored by analysing seismic shear, or S-waves
These waves arrive at seismic stations before secondary waves, or S-waves
, which shake molecules from side to side.
In several regions, such as south of the Indonesian island of Java or in the Coral Sea northeast of Australia, P-wave and S-wave
images show broad, plumelike features rising from the base of the mantle but extending only halfway to Earth's surface.
