SpletSeismic waves recorded at increasing distances from an earthquake indicate that seismic velocities gradually increase with depth in the mantle (exceptions: see Low Velocity Zone and 670 km Discontinuity above). However, at arc distances of between about 103° and 143° no P waves are recorded. Furthermore, no S waves are record beyond about 103°. SpletP-waves have speeds of 4 to 7 km/s, and S-waves have speeds of 2 to 5 km/s, but both are faster in more rigid materials.

Splet11. feb. 2016 · The experimental results show that the P-, S-, and R-wave velocities increased slightly (2-3%) when prestressing was applied. As expected, the S- and R-wave measurements show better statistical reliability and potential for in situ evaluation than the P-wave because they are less sensitive to confinement and boundary conditions.

"SpletIn general, the equation for the speed of a mechanical wave in a medium depends on the square root of the restoring force, or the elastic property, divided by the inertial property, v = elastic property inertial property. Also, sound waves satisfy the wave equation derived in Waves, ∂ 2 y ( x, t) ∂ x 2 = 1 v 2 ∂ 2 y ( x, t) ∂ t 2. " - S-waves speed

While S waves are able to travel through solids only, P waves can travel …

SpletRayleigh waves have a speed slightly less than shear waves by a factor dependent on the elastic constants of the material. The typical speed of Rayleigh waves in metals is of the order of 2–5 km/s, and the typical Rayleigh speed in the ground is of the order of 50–300 m/s for shallow waves less than 100-m depth and 1.5–4 km/s at depths ... http://www.columbia.edu/~vjd1/earth_int.htm

SpletThe S in S-waves stands for secondary, because they are the second-fastest seismic waves and the second type to be detected once an earthquake has occurred. Although S-waves are slower than P-waves, …

SpletS p e e d = 170 m / s + 170 m / s 1 s = 340 m / s Dependance on the Medium The speed of most waves depends on the medium in which it travels. Generally, waves travel fastest through solids and slowest through gases. This is because particles are closest together in solids and farthest apart in gases. frontline fife housing adviceSpletThey typically travel at speeds between ~1 and ~14 km/sec.
