Seismic Methods SpringerLink

The basic principle of all seismic methods is the controlled generation of elastic waves by a seismic source in order to obtain an image of the subsurface. Seismic waves are pulses of strain energy that propagate in solids and fluids. Seismic energy sources, whether at the Earth’s surface or in shallow boreholes, produce wave types known as:

Reflection seismology Wikipedia

OverviewHistoryOutline of the methodApplicationsEnvironmental impactSee alsoFurther readingExternal links

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, such as dynamite or Tovex blast, a specialized air gun or a seismic vibrator, commonly known by the trademark name Vibroseis. Reflection seismology is similar to sonar and echolocation. This article is about surface seismic surveys; for vertical seismic profile

Seismic methods involve measuring the propagation of seismic waves through earth materials. In seismic surveys, seismic waves radiate outward from a sound source at the surface, which can be an explosive charge or a mechanical impact. The refraction technique uses a long array of geophones to sense refracted waves, and the reflection technique uses a condensed array near the source to sense
