seismic wave velocity
1Seismic wave — Seismic waves are waves that travel through the Earth, most often as the result of a tectonic earthquake, sometimes from an explosion. Seismic waves are also continually excited by the pounding of ocean waves and the wind. Seismic waves are… …
2wave velocity — ▪ physics distance traversed by a periodic, or cyclic, motion per unit time (in any direction). Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction. The velocity of a wave is equal to the… …
3seismic wave — 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… …
4Seismic microzonation — map of Greater Bangkok prepared based on predominant period of site obtained from microtremor observations [1] Main article: Earthquake engineering Seismic microzonation is defined as the process …
5Seismic tomography — is a methodology for estimating the earth s properties. In the seismology community, seismic tomography is just a part of seismic imaging, and usually has a more specific purpose to estimate properties such as propagating velocities of… …
6Wave propagation — is any of the ways in which waves travel through a waveguide.With respect to the direction of the oscillation relative to the propagation direction, we can distinguish between longitudinal wave and transverse waves.For electromagnetic waves,… …
7Seismic shadowing — is a global effect of an earthquake. The seismic waves generated by an earthquake pass through the body of the Earth, but between 104° and 140° from the focus of an earthquake, little or no seismic waves can be detected. This is because primary… …
8wave — waveless, adj. wavelessly, adv. wavingly, adv. wavelike, adj. /wayv/, n., v., waved, waving. n. 1. a disturbance on the surface of a liquid body, as the sea or a lake, in the form of a moving ridge or swell. 2. any surging or progressing movement …
9Wave — /wayv/, n. a member of the Waves. Also, WAVE. [1942; see WAVES] * * * I In oceanography, a ridge or swell on the surface of a body of water, normally having a forward motion distinct from the motions of the particles that compose it. Ocean waves… …
10Wave — A wave is a disturbance that propagates through space and time, usually with transference of energy. While a mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces), waves of electromagnetic… …
