Seismic wave - Wikipedia
A seismic wave is a mechanical wave of acoustic energy that travels through the Earth or another planetary body. It can result from an earthquake (or generally, a quake), volcanic eruption, magma movement, a large landslide and a large man-made explosion that produces low-frequency acoustic energy.
Seismic Waves: Definition, Types, Examples, and Diagram
2020年4月11日 · Seismic waves are energy waves that are generated by an earthquake or explosion and propagate within the Earth or on its surface. Earthquakes occur when there is a movement of Earth’s tectonic plates.
Seismic wave | Earth’s Interior Structure & Movement | Britannica
Seismic wave, vibration generated by an earthquake, explosion, or similar energetic source and propagated within the Earth or along its surface. Earthquakes generate four principal types of elastic waves; two, known as body waves, travel within …
Seismology | UPSeis | Michigan Tech - Michigan Technological University
Seismic waves are caused by the sudden movement of materials within the Earth, such as slip along a fault during an earthquake. Volcanic eruptions, explosions, landslides, avalanches, and even rushing rivers can also cause seismic waves. Seismic waves travel through and around the Earth and can be recorded with seismometers.

2023年11月27日 · S-waves (Secondary or Shear Waves): S-waves are slower than P-waves and can only travel through solids. They cause particles to move perpendicular to the wave direction, resulting in a shearing or side-to-side motion. Surface Waves: These waves travel along the Earth’s surface and are typically more destructive during earthquakes.
Seismic Waves and Earth's Interior - Pennsylvania State University
Seismic waves are propagating vibrations that carry energy from the source of the shaking outward in all directions. You can picture this concept by recalling the circular waves that spread over the surface of a pond when a stone is thrown into the water.
S Waves : Earthquakes waves, P waves, S waves & Surface waves - BYJU'S
S waves also called secondary waves and shear waves, are the second waves to hit the seismographs. They are transverse waves, which means that the motion is perpendicular to the direction of wave propagation .
Seismic Wave Motions—4 waves animated - IRIS
An earthquake generates seismic waves that penetrate the Earth as body waves (P & S) or travel as surface waves (Love and Rayleigh). Each wave has a characteristic speed and style of motion. The animations below illustrate both the propogation of the wave as well as the motion of particles as the wave passes.
8.3: Seismic Waves - Geosciences LibreTexts
S-waves are shear waves (though that is not what the S stands for). They move by material flexing or deforming sideways (shearing) from the direction of wave travel, and then returning to the original shape once the wave passes. The speed at which S-waves travel through material is determined only by: rigidity — how strongly the material ...

2018年11月23日 · Seismic waves can either be body waves or surface waves -- but the full story is far more complex. Generally speaking, there are two types of waves: body waves (which comprise of P or...
