Seismology, using controlled sources and earthquakes, is the primary tool for determining the subsurface structure of the Earth, at all scales. Other geophysical techniques also help, and the inversion of various geophysical data to produce models of subsurface geology is becoming increasingly sophisticated. Faculty members are active researchers in various facets of Earth imaging, as follows.

Geophysical Inversion is a numerical technique for making best estimates of subsurface structure from geophysical data constrained by limited geological information.
