Dear colleagues!
It has been a weird year for scientific meetings, and we have all
missed important aspects of them: the spontaneous bumping into people
at coffee, the nice conversations at lunch & the lively poster session
discussions.Even though these will still be somewhat missing from
vEGU2021, we cordially invite you to join our session "Ambient seismic
noise seismology: Topics, targets, tools & techniques" (abstract
below). Abstracts can be submitted until 13 January 2021 at
https://meetingorganizer.copernicus.org/EGU21/session/39296.
There are a range of interesting new developments in ambient seismic
noise and seismic interferometry that merit our attention, such as the
the use of opportunistic sources, the study of cultural noise, or the
collection of data with new sensors like DAS. Virtual conferencing,
improved by iteration, could become a useful complement to live
conferences, diminishing our CO2 budgets and making participation
easier for people facing obstacles to attending in-person meetings.
So, although we will greatly miss ambling through Vienna with you, we
hope to see you at vEGU 2021!

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.
