Dear Colleagues,
We would like to draw your attention to a special session at the Fall
AGU meeting.
This sessions is about seismic interferometry and noise correlations and
recent advances in this relatively new field in seismology. We invite
you to submit an abstract on a broad spectrum of topics of seismic
interferometry, including theoretical developments, retrieval of body
waves, higher mode surface waves or attenuation, monitoring using
interferometry, characterization of noise sources and their effect on
Green's function retrieval, and of course their application in seismic
imaging and tomography. A more complete description is attached below.
S21: Go Boldly With Seismic Noise and Interferometry: A New Field in
Seismology
Sponsor: Seismology
Description:
Theoretical, experimental, and observational studies have shown that the
Green’s function between two receivers can be recovered from seismic
interferometry through cross correlation or deconvolution of (ambient
noise) wave fields under particular conditions. This method has recently
been used successfully for seismic tomography or as applied to seismic
exploration data and is slowly becoming a standard method in seismology.
Further analysis of this new tool shows significant promise of a more
widespread application, including seismic monitoring of volcanoes, fault
zones, reservoirs, and engineering structures, ground motion prediction
and attenuation measurements in addition to improved tomographic
modeling. Seismic interferometry studies at various scales have
successfully extracted the surface wave part of the Green’s function but
so far still has difficulty in retrieving the body wave part. We
encourage contributions from: (1) theoretical and numerical studies on
realistic heterogeneous media. (2) advanced signal processing techniques
for the Green’s function retrieval, especially for the body wave part.
(3) tomographic applications including anisotropy from seismic
interferometry in a broad scale range. (4) Monitoring using seismic
noise, attenuation from the noise or ground motion prediction (5)
characterization and effects of the uneven distribution of ambient noise
energy and medium complexities on the Green’s function retrieval (6)
other novel developments of seismic interferometry, or the use of
“other” energy sources.
