Seismic S waves, also known as shear or secondary waves, travel through solids. They are not able to propagate through liquids or gases because they require a medium with particles that can move past one another, which is a characteristic of solid materials. S waves are slower than P waves (primary waves) and are缺席 (absent) in liquids and gases due to the lack of this particle movement capability.

Both types of seismic wave can be detected near the earthquake centre but only P-waves can be detected on the other side of the Earth. This is because P-waves can travel through solids and liquids whereas S-waves can only travel through solids. This means the liquid part of the core blocks the passage of S-waves.
