Dear Colleagues,

We would like to draw your attention to our session *"SM4.3: Ambient
seismic noise techniques: sources, monitoring, and imaging" *at the 2017
EGU General Assembly in Vienna, Austria.

The session will feature invited presentations by:

+ Parisa Shokouhi (Penn State University) "Nonlinear elastic behavior of
rocks revealed by dynamic acousto-elastic testing"
+ Peter Bromirski (Scripps Institute of Oceanography) "Continuous
gravity-wave-induced ice shelf shaking"

The EGU takes place from 23–28 April 2017 and abstracts can be
submitted until *11 January 2017, 13:00 CET* through the following link:
You will also find more information about the session there.

Please inform your colleagues and students about this opportunity to
present their work. We look forward to your contributions.

Happy Holidays,

Ambient seismic noise techniques: sources, monitoring, and imaging

*Session Description:*
Microseisms, once regarded as a nuisance, are now a core part of the
seismological toolkit. They are a key element of a revolution in passive
seismic imagery using noise sources and have been used to generate
seismic images in a variety of settings. Despite these advances there
are many unknowns regarding the microseism sources themselves: their
detailed locations, their spatial and temporal distribution, the
partitioning of the seismic wavefield at the source location. These
variables likely affect the stability of seismic ‘noise correlation’
images and play an important role, especially in time-lapse imagery.
There is also growing interest in using passive seismic imagery for
time-lapse studies, due the continuously available noise sources. The
effects of dynamic processes in the Earth's crust on the propagation
velocity of seismic waves have been observed in numerous investigations
including earthquake triggering and relaxation, volcano and landslide
dynamics as well as production from hydrocarbon reservoirs and
geothermal fields.

In this session, we will cover all aspects of seismic interferometry and
ambient noise based seismology. We invite contributions concerning
multi-scale applications using seismic noise or interferometry, such as
imaging structure and monitoring subsurface changes. This extends to
evaluations of the accuracy of noise-based measurements for use in
tomography or time-dependent imaging. Of interest are also theoretical
advances, such as those exploring the role of source distribution or
scattering, as well as methodological improvements and alternative
processing techniques aimed at improving the quality of the
correlations. Finally, we welcome abstracts investigating the sources of
ambient seismic noise (microseisms, hum, microbaroms, etc) and their
generation processes. As cooperation among scientists across Europe on
the topic of noise studies is now supported through the COST-action
"TIDES" (TIme DEpendent Seismology), we encourage contributions from
participating institutions.
