Seismic interferometry and stationary phase at caustics

Waves that propagate between two receivers can be extracted by cross correlating noise recorded at these receivers if the noise is generated by sources on a closed surface surrounding the receivers. This concept is called seismic interferometry. Of all these noise sources, those for whom the travel time difference for propagation to the two receivers is in the stationary phase zone, give the do...

Seismic Interferometry by Deconvolution: Theory and Examples

Seismic interferometry is a field of growing interest in exploration seismology. In this paper we provide the theoretical basis for performing interferometry by deconvolution. We argue that for arbitrarily complicated models, deconvolution interferometry gives the causal scattering response between any two receivers. Interferometry by cross-correlation, on the other hand, gives both causal and ...

Seismic interferometry, intrinsic losses and Q-estimation∗

Seismic interferometry is the process of generating new seismic traces from the crosscorrelation, convolution or deconvolution of existing traces. One of the starting assumptions for deriving the representations for seismic interferometry by crosscorrelation is that there is no intrinsic loss in the medium where the recordings are performed. In practice, this condition is not always met. Here, ...

Event-driven Seismic Interferometry with Ambient Seismic Noise

SUMMARY By cross-correlating recordings of ambient seismic noise, one can retrieve the subsurface reflection response. The quality of the retrieved reflections would depend on the qualities of the ambient noise. In a previous study, we cross-correlated ambient-noise data recorded in a desert area in North Africa and showed that we retrieved reflections. This was done assuming that body-wave noi...

A Comparison of Strategies for Seismic Interferometry

The extraction of the response from field fluctuations excited by random sources has received considerable attention in a variety of different fields. We present three methods for the extraction of the systems response that are based on cross-correlation, deconvolution, and the solution of an integral equation, respectively. For systems that are invariant for time-reversal the correlation metho...
