Abstract
A new field in seismology has recently emerged based on analyzing seismic interference patterns, i.e., crosscorrelograms (Rickett and Claerbout, 1999; Schuster, 2001; Yu and Schuster, 2001; Wapenaar et al., 2002, Calvert et al., 2004 and others). Analogous to optical interferometry, seismic interferometry estimates the detailed properties of an elastic medium by analyzing the interference patterns of seismic waves. The interference patterns are constructed by correlating seismic traces with one another and can sometimes be used to robustly image the earth's elastic properties compared to standard seismic imaging. In this report I discuss some key benefits, liabilities and examples of seismic interferometry.
