| Summary: | <p>The earthquake seismology and seismic exploration communities have developed a
variety of seismic imaging methods for passive- and active-source data.
Despite the seemingly different approaches and underlying principles, many of
those methods are based in some way or another on Green's theorem. The aim of
this paper is to discuss a variety of imaging methods in a systematic way,
using a specific form of Green's theorem (the homogeneous Green's function
representation) as a common starting point. The imaging methods we cover
are time-reversal acoustics, seismic interferometry, back propagation,
source–receiver redatuming and imaging by double focusing. We review
classical approaches and discuss recent developments that fully account for
multiple scattering, using the Marchenko method. We briefly indicate new
applications for monitoring and forecasting of responses to induced seismic
sources, which are discussed in detail in a companion paper.</p> |
