<p><b>Seismic tomography</b> or <b>seismotomography</b> is a technique for imaging the subsurface of the Earth using <a href="page.php?w=seismic_wave">seismic wave</a>s. The properties of seismic waves are modified by the material through which they travel. By comparing the differences in seismic waves recorded at different locations, it is possible to create a model of the subsurface structure. Most commonly, these seismic waves are generated by <a href="page.php?w=earthquake">earthquake</a>s or <a href="page.php?w=Seismic_source">man-made sources</a></p><p>
