  1. 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 …

  2. What causes earthquakes? The science behind why seismic ... - AOL

    Dec 5, 2024 · An earthquake is what happens when the seismic energy from plates slipping past each other rattles the planet's surface. Those seismic waves are like ripples on a pond, the USGS said.

  3. Seismology - Wikipedia

    Seismic waves are elastic waves that propagate in solid or fluid materials. They can be divided into body waves that travel through the interior of the materials; surface waves that travel along surfaces or …

  4. Seismic noise - Wikipedia

  5. Shadow zone - Wikipedia

    A seismic shadow zone is an area of the Earth 's surface where seismographs cannot detect direct P waves and/or S waves from an earthquake. This is due to liquid layers or structures within the Earth's …

  6. Seismic velocity structure - Wikipedia

    The velocity structure of the Earth. The red line is the P-wave velocity, the blue line is the S-wave velocity, and the green line density. (Data was adopted from the RockHound Python library.) Seismic …

  7. Earthquake - Wikipedia

    The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic …

  8. Ground motion - Wikipedia

    Ground motion is produced by seismic waves that are generated by sudden slip on a fault or sudden pressure at the explosive source and travel through the Earth and along its surface. [1] This can be …
