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.
Earthquake - Seismic Waves, Properties, Geology | Britannica
2 days ago · Earthquake - Seismic Waves, Properties, Geology: At all distances from the focus, mechanical properties of the rocks, such as incompressibility, rigidity, and density, play a role in the speed with which the waves travel and the shape and duration of the wave trains.
Seismic Waves: Definition, Types, Examples, and Diagram
Apr 11, 2020 · 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 the Earth, whereas the other two, called surface waves, travel along its surface.

9.1: Understanding Earth Through Seismology - Geosciences …
Apr 24, 2024 · Before going any deeper into Earth, however, we need to take a look at the properties of seismic waves. The types of waves that are useful for understanding Earth’s interior are called body waves, meaning that, unlike the surface waves on the ocean, they are transmitted through Earth materials.
Seismic Wave Speeds and Rock Properties - University of …
For example, we've shown that reflected waves can be generated from a planar boundary in seismic wave speed that can be recorded at the Earth's surface. How do these velocity variations relate to properties of the rocks or soils through which the waves are propagating?
6.6: Seismic Waves - Geosciences LibreTexts
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.
8.2 Seismic Waves – Exploring Physical Geology Lab Online
8.2 Seismic Waves Properties of Waves. Earthquakes are releases of energy that travel through seismic waves. These waves have the same properties as waves caused by moving water or sound. So let’s quickly review what the basic properties of a wave are.
Seismic Properties The propagating seismic wave has two very important intrinsic elements, which are indispensable to the framework of exploration seismic technology. These are: (1) amplitude of the seismic wave – particle velocity measured by …
