Love waves (also named Q waves) are surface seismic waves that cause horizontal shifting of the earth during an earthquake. The are named after A.E.H. Love, who calculated the waves mathematically in 1911. In physics, a surface wave is a wave that is guided along the interface between two different media for a mechanical wave, or by a refractive index gradient for an electromagnetic wave. ... A seismic wave is a wave that travels through the Earth, often as the result of an earthquake or explosion. ...
