"WebWaves whose amplitude of moton is parallel to the surface are called Love waves (named after the mathematician A. E. H. Love who modeled them - definitely not an indication that anyone is fond of them). Rayleigh waves or ground roll waves cause the surface of the ground to move up and down. They travel at roughly 90% of the speed of the S waves. " - Rayleigh waves is also known as ground roll

WebMay 1, 2016 · Ground-roll, the vertical component of Rayleigh wave, is a secondary wave that travels along the free surface, such as the earth–air interface or the earth–water interface. It has the significant characteristics of relatively low velocity, low frequency, high amplitude and strong energy (Sheriff, 2002). Web1. Love Waves are known for bringing surface shifting on the surface of the earth's crust. Rayleigh waves follow the elliptical motion. 2. Love waves are faster than Rayleigh waves but slower than Body Waves. Rayleigh waves roll around the ground bringing up and down + forward and backward motion. 3. Love waves are rare and exist in a semi ...

WebLow-frequency, low-velocity interface waves encountered in seismic prospecting commonly arising from the ground-air interface, in which case they are known as Rayleigh waves.
