Rayleigh waves move the surface of the earth around in a circle, forward and down then back and up. In seismology, Love waves (also known as Q waves (Quer: German for lateral)) are surface seismic waves that cause horizontal shifting of the Earth during an earthquake. endobj They show the dependence of the velocity on layer thicknesses and material properties (elastic constants). 0000005157 00000 n This answer has been confirmed as correct and helpful. 0000037968 00000 n Deeper in the ground, Rayleigh and Love waves get smaller. << /Filter /FlateDecode /S 216 /Length 343 >> I.

Rayleigh wave definition, a wave along the surface of a solid, elastic body, especially along the surface of the earth. The theory includes the effect of layering and source depth for the following: (1) Rayleigh waves from an explosive source, (2) Rayleigh waves from a vertical point force, (3) Rayleigh and Love waves from a vertical strike slip fault model. Thus, Love waves cannot be generated exclusively by the scattering of Rayleigh waves. 0000046346 00000 n These waves produce only horizontal motion on the Earth's surface shaking the Earth in a side to side motion.

Their relatives, the Rayleigh waves, lag behind slightly, but still speed at about 7800 miles an hour. Since seismic recordings are measures of earth displacement, particle velocity, or water pressure over elapsed time, this means the waves show up at different times in the record. At periods of 1 sec or less, the surface amplitudes of both Love and Rayleigh waves increase considerably with distance south into the valley as the alluvium thickens. A. B.
