A surface wave that travels when a different surface layer is placed on a semi-infinite elastic body with a horizontal boundary surface. It is a transverse wave, and a mass point in the medium only vibrates horizontally. A. Love proved the possibility of the existence of this wave. The amplitude decreases rapidly with depth, and the shorter the wavelength, the greater the attenuation. In seismic waves, it is observed after S waves.

境界面が水平である半無限弾性体の上に異なる表層があるときに伝わる表面波。横波であって,媒質中の質点は水平振動だけをする。 A.ラブがこの波の存在の可能性を証明した。振幅は深さとともに急速に減少し,波長が短いほど減衰は著しい。地震波では,S波のあとに観測される。
