refraction seismic
1Seismic source — This article is about artificial seismic sources. For natural seismic sources, see Earthquake, Volcano, and related articles. A seismic source generates controlled seismic energy that is used in both reflection and refraction seismic surveys. A… …
2Seismic refraction — is a geophysical principle (see refraction) governed by Snell s Law. Used in the fields of engineering geology, geotechnical engineering and exploration geophysics, seismic refraction traverses (seismic lines) are performed using a seismograph(s) …
3Refraction microtremor — (ReMi) is a surface performed geophysical survey developed by Dr. John Louie (and others) based on previously existing principles of evaluating surface waves and in particular Rayleigh waves. Since Rayleigh waves are dispersive, the propagating… …
4Seismic 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… …
5Seismic Unix — is an open source seismic utilities package supported by the Center for Wave Phenomena (CWP) at the Colorado School of Mines (CSM).Infobox Software name = Seismic Unix caption = Velocity Analysis with SU developer = [http://www.cwp.mines.edu/… …
6Seismic 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… …
7seismic survey — method of investigating subterranean structure, particularly as related to exploration for petroleum, natural gas, and mineral deposits (mineral deposit). The technique is based on determinations of the time interval that elapses between… …

9Negative refraction — is the name for an electromagnetic phenomenon where light rays are refracted at an interface in the reverse sense to that normally expected. Such an effect can be obtained using a metamaterial which has been designed to achieve a negative value… …
10Outline of geophysics — Seismic velocities and boundaries in the interior of the Earth sampled by seismic waves. The following outline is provided as an overview of and topical guide to geophysics: Geophysics – the physics of the Earth and its environment in space; also …
