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 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.

WebSF Table 7.1 shows that P waves have a higher velocity than S waves when traveling through several mineral types. The speed at which seismic waves travel depends on the properties of the material that they are passing through. For example, the denser a material is, the faster a seismic wave travels (SF Table 7.1). Web24 feb. 2024 · Of the two surface waves, Love waves move faster.
