. Когда записи различных приемников сигнала суммируются, амплитуда нужного сигнала увеличивается, а ненужные сигналы при сложении взаимоуничтожаются и амплитуда их становится небольшой по сравнению с амплитудой нужного сигнала.)English-Russian oil and gas dictionary with explanation. 2014.
Seismic 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… … Wikipedia
Seismic 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) … Wikipedia
Reflection seismology — (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth s subsurface from reflected seismic waves. The method requires a controlled seismic source of energy,… … Wikipedia
Seismoelectrical Method — Basic ConceptThe Seismoelectrical method (also called the Electroseismic method or [http://www.agu.org/meetings/fm06/fm06 sessions/fm06 NS21A.html seismic electric] ) is based on the generation of electromagnetic fields in soils and rocks by… … Wikipedia
earthquake — /errth kwayk /, n. 1. a series of vibrations induced in the earth s crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating. 2. something that is severely disruptive; upheaval. [1300 50; ME erthequake … Universalium

Seismometer — Seismometers (from Greek Seism the shakes and Metro I measure ) are instruments that measure and record motions of the ground, including those of seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of… … Wikipedia
Nigel Anstey — Nigel Allister Anstey, British geophysicist, has made major contributions to seismic exploration, which are the foundations for many of the techniques used in today’s oil and gas exploration. Anstey’s contributions impact every major area of… … Wikipedia
Refraction 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… … Wikipedia
