The past decade witnessed rapid development of the theory of seismic interferometry followed by numerous applications of interferometric approaches in seismic exploration and exploitation. This body of work, partially collected in the “Seismic Interferometry” supplement of Geophysics (2006), SEG's 2008 reprint volume edited by Wapenaar et al., and the “Interferometry Applications” special section of The Leading Edge (2011), conclusively demonstrates that a stack of crosscorrelations of traces recorded by two receivers over sources appropriately distributed in a three-dimensional heterogeneous Earth can retrieve a signal that would be observed at one receiver if another acted as a source of seismic waves. This assertion is applicable to both active-source data (many instructive geometries of this kind are examined by Schuster, 2009) and passive records of ambient noise; examples of the latter, summarized by Snieder and Wapenaar (2010), range from ultrasonics (Weaver and Lobkis, 2001) to global seismology (Shapiro et al., 2005).
