S wave geology definition
Splet11. avg. 2024 · S wave: [noun] a wave (as from an earthquake) in which the propagated disturbance is a shear in an elastic medium (such as the earth) — compare pressure wave. SpletS -waves can originate and propagate only in solids. Lithology can be determined more readily from both P - and S -wave velocities ( Vp, Vs) than from P -wave data alone. The Vp / Vs ratio, the common seismic attribute derived from multicomponent seismic data, can be used to predict rock type.
