Web1 wavelength from the surface) particle motion of a Rayleigh wave is a counter-clockwise elliptical motion. Love waves travel at a lower velocity than the bulk waves (compression waves and shear waves), but faster than Rayleigh waves. In this article we will illustrate the A-scan (voltage displacement) of Rayleigh wave signals In the case of local or nearby earthquakes, the difference in the arrival times of the P and S waves can be used to determine the distance to the event. In the case of earthquakes that have occurred at global distances, three or more geographically diverse observing stations (using a common clock) recording P-wave arrivals permits the computation of a unique time and location on the planet for the event. Typically, dozens or even hundreds of P-wave arrivals are used to calculate

WebIn the Earth, P waves travel at speeds from about 6 km (3.7 miles) per second in surface rock to about 10.4 km (6.5 miles) per second near the … WebRayleigh waves are slower than body waves and typically travel at a speed that is 10% slower than S-waves. Rayleigh waves propagate through the ground as ripples. Love waves Love waves have the same motion as S-waves but …

WebWhen they travel through air, they take the form of sound waves – they travel at the speed of sound (330 ms -1) through air but may travel at 5000 ms -1 in granite. Because of their speed, they are the first waves to be recorded by a seismograph during an earthquake. Web26 feb. 2010 · 3. Seismic Wave Animations: Seismic wave animations for the P, S, Rayleigh and Love waves have been created using a 3-D grid shown in Figure 1. All wave types are designed to propagate in the X direction (illustrated in Figure 1) and parallel to the Earth’s surface. The wave animations illustrate wave characteristics and particle motion …
