{{Main|Surface wave}}
This type of wave travels along the surface or [[interface (matter)|interface]] between two media. An example of a surface wave would be waves in a pool, or in an ocean, lake, or any other type of water body. There are two types of surface waves, namely [[Rayleigh wave]]s and [[Love wave]]s.

Rayleigh waves, also known as ''ground roll'', are waves that travel as ripples with motion similar to those of waves on the surface of water. Such waves are much slower than [[body wave (seismology)|body wave]]s, at roughly 90% of the velocity of {{clarify span|text=bulk waves|explain=What are "bulk waves"?|date=October 2018}} for a typical homogeneous elastic medium. Rayleigh waves have energy losses only in two dimensions and are hence more destructive in [[earthquake]]s than conventional bulk waves, such as [[P-wave]]s and [[S-wave]]s, which lose energy in all three directions.

A Love wave is a surface wave having horizontal waves that are shear or transverse to the direction of propagation. They usually travel slightly faster than Rayleigh waves, at about 90% of the body wave velocity, and have the largest amplitude.
