Seismic tomography. Seismic 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 seismograph array coverage. The data received at seismometers are used to solve an inverse problem, wherein the locations of reflection and refraction of the wave paths are determined. This solution can be used to create 3D

Seismic waves are waves produced by earthquakes. This occurs when rocks under the earth suddenly break or explode. There are two main types of seismic waves called body waves and surface waves. Body waves have the capacity to travel through the Earth's inner layers.
