Seismic 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… … Wikipedia
seismic 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… … Universalium
arrival time — 1. The time of arrival in subsurface flow tracing for the first tracer pulse to arrive at a discharge location. 2. The time of arrival in geophysics for the first seismic wave to arrive at a geophone [16] … Lexicon of Cave and Karst Terminology
Seismic 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… … Wikipedia
