S33D:
Ambient Field Seismology: Theoretical and Methodological Innovations II

Submit an Abstract to this Session



Session ID#: 32722

Session Description:
Ambient field (noise) correlations are largely used to assess Earth’s properties such as seismic velocities, medium stiffness, or attenuation. Recent studies attempt to gain additional information with high spatial sampling or continuous time-lapse measurements. However, all correlation studies strongly depend on accurate estimation of the Green’s function (GF), which relies on, for example, microseism sources distribution, receiver coverage, and signal processing.

In this session, we would like to cover all theoretical and methodological aspects of ambient field seismology. We are enthusiastic to receive innovative studies exploring the source distribution or the importance of scattering and their influence on the accuracy of the GF recovered. We encourage abstracts investigating time-dependent imaging and multiscale imaging applications that involve novel processing such as higher-order correlations, double beamforming, multi-dimensional deconvolution, or very dense receiver array analysis. Presentations related to amplitude extraction, higher-mode Rayleigh/Love waves, body waves, or usage of multi-component signals are also encouraged.
