Seismic Waves Earthquake Types & Concept - Study.com

WebSeismic wave— A vibrational disturbance in the Earth that travels at speeds of several kilometers per second. There are three main types of seismic waves in the earth: P (fastest), S (slower), and Surface waves (slowest). Seismic waves are produced by earthquakes. Seismogram—real-time record, made of metal tape, of seismic waves. WebOf the two surface waves, Love waves move faster. Rayleigh waves cause the ground to shake in an elliptical pattern. This motion is similar to that observed in ocean waves. How do Rayleigh waves move? Rayleigh Waves—surface waves that move in an elliptical motion, producing both a vertical and horizontal component of motion in the direction ...

WebLove waves have a horizontal motion that moves the surface from side to side perpendicular to the direction the wave is traveling. Of the two surface waves, Love waves move faster. Rayleigh waves cause the ground to shake in an elliptical pattern. This motion is similar to that observed in ocean waves. Web5 mrt. 2024 · It is not surprising for the shock wave to be found in the Rayleigh flow. Example 11.26. One of the reason that Rayleigh flow model was invented is to be analyzed the flow in a combustion chamber.
