Web[1] Rayleigh wave ellipticity as a function of frequency is closely linked to underground structure, i.e., shear wave velocity profile and sediment thickness. The possibility to calculate these underground properties by inverting ellipticity curves has recently been shown.

WebLove waves shake the surface side-to-side. Rayleigh waves move the surface of the earth around in a circle, forward and down then back and up. This is the same as the motion in an ocean wave. Deeper in the ground, Rayleigh and Love waves get smaller. Underground miners seldom feel the motion of these surface waves. WebSeismic waves generated by an earthquake source are commonly classified into three main types. The first two, the P (or primary) and S (or secondary) waves, propagate within the body of the Earth, while the third, consisting of Love and Rayleigh waves, propagates along its surface. The existence of these types of seismic waves was mathematically predicted …
