WebS-waves can travel only through solids, as fluids (liquids and gases) do not support shear stresses. S-waves are slower than P-waves, and speeds are typically around 60% of that of P-waves in any given material. Shear waves can't travel through any liquid medium, so the absence of S-waves in earth's outer core suggests a liquid state. WebP-waves are fastest and are the first signal to arrive on a seismogram, followed by the slower S-wave, then the surface waves. The arrival times of the P- and S-waves at different seismometers are used to determine the location of the earthquake. Assuming that we know the relative speed of P- and S-waves, the time difference between the ... chipper in bray

Web12 de jan. de 2024 · In general, S waves are only 60 percent as fast as p waves. So, along Earth’s surface they move at speeds of between 3 and 4.8 kilometers per second (1.9 and 3 miles per second). As an S wave passes through a material, the site of its passing moves from side to side or up and down (as compared to the direction the wave is traveling).

WebP waves are like the lightning, and S waves are like the thunder. The P waves travel faster and shake the ground where you are first. Then the S waves follow and shake the ground also. If you are close to the earthquake, the P and S wave will come one right after the other, but if you are far away, there will be more time between the two.
