The four main types of seismic waves are P waves, S waves, Love waves, and Rayleigh waves. Encyclopædia Britannica, Inc. Discern between body and surface waves, primary and secondary waves, and Love and Rayleigh wavesThere are three major types of seismic surveys: refraction, reflection, and surface-wave depending on the specific type of waves being utilized. Each type of seismic survey utilizes a specific type of wave (for example, reflected waves for reflection survey) and its specific arrival pattern on a multichannel record (Fig. 3).

Seismologists use seismic waves to learn about earthquakes and also to learn about the Earth’s interior. The two types of seismic waves described in “Plate Tectonics,” P-waves and S-waves, are known as body waves because they move through the solid body of the Earth. P-waves travel through solids, liquids, and gases.Seismometers allow us to detect and measure earthquakes by converting vibrations due to seismic waves into electrical signals, which we can then display as seismograms on a computer screen. …Difference between p waves and s waves. P waves. S waves. P waves are the first wave to hit the earth’s surface. These arrive after P waves. These waves travel in the speed range of 1.5-13 km/s. These waves are almost 1.7 times slower than P waves. These waves travel in a linear direction. These waves travel in a transversal direction.

Waves that carry energy away from the earthquake are called seismic waves. Seismometers can be used to measure the magnitudes of earthquakes. P-waves are longitudinal body waves that can travel through solid ground and water. P-waves are the fastest seismic waves and travel faster in solids than in water.

Waves Tell Stories. Waves from a large quake can travel long distances and pass through many different types of material inside a planet. All of those different materials alter the wave in their own way. To understand what the inside of a planet is really like, SEIS had the ability to listen to a host of different variations in seismic waves ...Seismographs - Keeping Track of Earthquakes. By Earthquake Hazards Program. Throw a rock into a pond or lake and watch the waves rippling out in all directions from the point of impact. Just as this impact sets waves in motion on a quiet pond, so an earthquake generates seismic waves that radiate out through the Earth.

Danish seismologist Inge Lehmann “the only Danish seismologist,” as she once referred to herself—studied the shock waves and was puzzled by what she saw. A few P-waves, which should have been deflected by the core, were in fact recorded at seismic stations. Lehmann theorized that these waves had traveled some distance into the core and ... The first set of waves to be detected by seismographs are P waves, or primary waves, as they’re the fastest. They’re compressional or longitudinal waves that push and pull the ground in the direction the wave is traveling. They usually cause very little damage. S waves, or secondary waves, come next since they travel more slowly than P waves.Meanwhile, long period waves are sensitive to larger volumes or, in the case of normal modes, the whole Earth. The frequencies of seismic data used to construct the model affect how the resulting model should be used. Seismic data can be supplemented by other measurements, such as astronomical data.
