An elastic wave generated by an impulse such as an earthquake or an explosion Seismic waves may travel either along or near the earth's surface ( Rayleigh and Love waves) or through the earth's interior (P and S waves)
Vibration generated by an earthquake, explosion, or similar phenomenon and propagated within the Earth or along its surface. Earthquakes generate two principal types of waves: body waves, which travel within the Earth, and surface waves, which travel along the surface. Seismograms (recorded traces of the amplitude and frequency of seismic waves) yield information about the Earth and its subsurface structure; artificially generated seismic waves are used in oil and gas prospecting
Seismic waves are vibrations caused by earthquakes that are picked up on machines called seismographs There are however two different types of seismic waves and they are pressure waves and shear waves Pressure waves are a lot like sound waves and shear waves have to have something with more of a substance like jelly instead of water so it can move it
