See all on Wikipediahttps://en.wikipedia.org/wiki/Seismic_tomographySeismic tomography is a technique for imaging the subsurface of the Earth with seismic waves produced by earthquakes or explosions. P-, S-, and surface waves can be used for tomographic models of different resolutions based on seismic wavelength, wave source distance, and the

Seismic tomography is a subset of seismic imaging that relies on using forward-scattered energy to map long-wavelength variations in the Earth's seismic velocity. Seismic imaging also incorporates reflection seismology techniques (analogous to ultrasound imaging in medicine) that use back-scattered energy.

- Seismic tomography has widely been used in earthquake seismology, but is also has applications for the exploration and development of oil and gas. The principles of tomography stay the same, but there are additional methods of seismic tomography that are used for oil and gas monitoring.
