Topics: EGU Meetings
Dear colleagues!
We'd like to draw your attention again to our session "Ambient seismic
noise seismology: Topics, targets, tools & techniques" (abstract
below). Five and a half days are left to submit an abstract (by 13
January 2021) at
https://meetingorganizer.copernicus.org/EGU21/session/39296.
In the meantime, we are delighted to announce that Sin-Mei Wu
(University of Utah) and Tom Eulenfeld (Friedrich-Schiller-Universität
Jena) have agreed to present their work on ambient noise monitoring of
volcanic / geothermal systems and inter-source interferometry. Besides
their presentations, the first abstracts that were submitted equally
promise a session that will have us discussing new ideas in ambient
noise studies. We are looking forward!
We hope to see many of you there,the conveners,Laura, Qingyu, Céline,
Anne and Christoph

Ambient seismic noise seismology: Topics, targets, tools & techniques
Conveners: Laura Ermert, Céline Hadziioannou, Anne Obermann, Christoph
Sens-Schönfelder, Qing-Yu Wang
Ambient seismic noise-based monitoring and imaging techniques have
matured into a core part of the seismological toolkit. The advantages
are based on the commonly obtained robust reconstruction of empirical
Green’s function estimates that allows seismic imaging and continuous
monitoring of a wide range of subsurface structures. In this session,
we focus on open questions and methodological advances in seismic
interferometry and ambient noise based seismology. We invite (A)
contributions on new methodological approaches in seismic
interferometry and noise processing (B) studies of time variations of
elastic material properties and (C) investigations of the sources of
the ambient seismic noise
This could, for example, include contributions that (A) further extend
the resolution capabilities and sensitivities of methods using the
continuously recorded wavefield and its applications; (B) propose ideas
that aim to push the imaging resolution of multiple scattered
wavefields; (C) report on case studies of established techniques that
are applied to data collected by unconventional solid earth and
acoustic acquisition systems such as distributed acoustic sensing
cables, rotation sensors, or infrasound installations; (D) investigate
causes of temporal variations of medium properties, including
suggestions for the upscaling of laboratory configurations to local and
regional scales; (E) show monitoring applications that connect the
obtained velocity change signals with complementary observables such as
seismicity rates, geodetic signals, or meltwater drainage to better
constrain underlying physical processes and model parameters; (F) study
the excitation of the ambient field over the entire frequency range and
implications for the stability of the reconstructed signals.
