A Love wave is a horizontally polarized shear wave trapped in a slower elastic surface layer above a faster elastic half-space. Zero shear traction at the free surface, displacement continuity and traction continuity at the interface produce its dispersion relation. A trapped mode has phase speed between the two shear speeds and decays exponentially into the half-space.
A Love wave is a type of surface seismic wave that travels along the Earth's surface and is named after the British mathematician A. E. H. Love, who first described them in the early 20th century. Love waves are characterized by a horizontal shearing motion that occurs in a horizontal plane perpendicular to the direction of wave propagation. Key characteristics of Love waves include: 1. **Motion**: Love waves involve side-to-side motion of the ground.
