How to distinguish P, S, Love, and Rayleigh waves in a seismogram?
These waves travel at different speeds: P-waves are fastest, then S-waves, then Love waves, then Rayleigh. 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.

Incident P-wave can transform to reflected P and SV waves. When the angle of incidence of P wave reaches 2nd critical angle, both outgoing P and SV waves propagate along the surface forming Rayleigh wave. So, P-wave by itself can form Rayleigh wave. At the same time, incident SV wave can transform to reflected P and SV waves.
Why does the shoreline sometimes recede prior to a Tsunami?
The particles in some surface waves, including wind waves and Rayleigh waves (a component of what is often called ground roll), have in a circular or elliptical motion — in the case of a wind wave the motion is clockwise if the wave is traveling from left to right (see this animated comparison for Rayleigh waves).

2015年7月13日 · The other surface wave form is called a Rayleigh wave. Unlike moving ocean waves, the Rayleigh waves move vertically as well as horizontally in a vertical plane pointing in the direction the waves are heading in. Surface waves travel slower than body waves (P and S); and love waves typically travel faster than Rayleigh waves from the two ...

2023年10月2日 · 2. **Rayleigh Waves:** - Rayleigh waves, also known as R-waves, are another type of surface seismic wave. - They are slower than Love waves and travel in a rolling motion, similar to ocean waves. - Rayleigh waves cause both vertical and horizontal ground motion, resulting in an elliptical or rolling motion of the ground.

2021年10月12日 · for V r (Rayleigh waves) I know the boundary conditions for V r , that is the half-space (null stress at the surface and null displacements and stress at infinite depth). What would be the boundary conditions for V p and V s solutions and why do they derivate for infinite medium and not half-space?

2017年4月6日 · The later body waves phases are of very low amplitude and are only detected by a sensitive seismometer. Also, at a short offset, it is often hard to pick later phases, even if they occur. There is a critical angle for seismic refraction , but not for reflection . 0-offset reflection originates just beneath the source.
