S11A:
Ambient Field Seismology: Theoretical and Methodological Innovations I


Submit an Abstract to this Session


Session ID#: 58687

Session Description:
The ambient seismic field (noise) is now widely used to assess a variety of features such as seismic velocities, medium stiffness, ground motion and attenuation. Recently, we have seen more attempts to gain spatial resolution and to extract body waves from noise correlations. Deep-phase extraction also offers global seismologists new opportunities to map Earth’s structures and to perform time-lapse studies. However, all these research topics strongly depend on the accurate estimation of the Green’s function, thus relying on, for example, microseism sources distribution, receiver coverage, and appropriate signal processing. In this session, we would like to cover most theoretical and methodological aspects of ambient-field seismology. We invite abstracts related to all the aforementioned research lines but also encourage innovative studies exploring the source distribution, the importance of scattering, and imaging applications involving novel processing such as higher-order correlations, double beam forming, or multi-dimensional deconvolution.
