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 Web23 mei 2024 · Rayleigh wave is a surface wave in which the particles make an elliptical movement against the direction of wave propagation. It is named after John Willam Strut, Lord Rayleigh, who in 1985 predicted its existence.

WebTypes of seismic waves: S-waves. Secondary waves or S-waves are seismic waves that travel at speeds of about 50% to 60% of the speed of the primary waves. Their effects are hence only felt after the effects of the P-waves during an earthquake. S-waves are also classified as body waves as they move along the inner layers of the Earth. WebGroup velocities of Love and Rayleigh waves are obtained by frequency time analysis of these noise free surface waves.
