<p>Dear colleagues,</p>
<p>we'd like to draw your attention to our session in the upcoming
EGU titled: <b>"Stability of the crust - strength and stress make
it"</b></p>
<p>We welcome all kinds of research from observations to
experimental studies, and laboratory results to numerical
modelling, independent whether it is a negative result, a failed
approach, some small step forward, or a groundbreaking finding. In
particular, we encourage Early Career Scientists to submit their
abstracts.</p>
<p>More details and abstract submission can be found here: <a

Please note the EGU-wide abstract submission deadline on <b>January
10th 12:00 CEST</b>.<br>
</p>
<p>Please help us spread the word and forward this call for
contributions to colleagues that might be interested.</p>
<p>Looking forward to see you in Vienna,</p>

Stability of the crust – strength and stress make it<br>
</p>
The mechanics of the Earth’s crust describes how the crust responds
to stresses resulting from geodynamic processes, gravitational
forces and anthropogenic activities. Knowledge of the key parameters
which propel or prevent current deformation processes is critical
for a better understanding of plate tectonics, earthquake processes,
and geohazards up to engineering applications.<br>
Despite the intensive research of the last decades in the context of
the mechanics of the Earth's crust, there are still many unknowns
about the current stress state and the relevant rock properties.
Major obstacles in advancing our understanding arise from the fact
that 1) deformation conditions in nature typically include more
complexities than those in laboratory experiments, 2) the full
stress tensor is laterally heterogeneous and difficult to determine,
3) fluid-rock interactions modify the distribution of stresses and
crustal deformation modes, 4) investigations typically cover
specific spatial and/or temporal scales, without a comprehensive
view on possible heterogeneities in space and time, and 5) too
little data is available and/or data is not openly accessible. We
must therefore advance and develop mechanical concepts, experiments,
measuring methods and data compilations, allowing to refine the
models describing the constitutive behavior. This helps to address
the main challenges, that is to quantify and reduce existing
uncertainties. Ultimately this improves the predictive quality of
our models and therefore the current understanding of crustal
stability.<br>
In this session we seek contributions that advance the current
understanding of the governing mechanics, the in-situ stress state,
and the strain field of the Earth’s crust via modelling, recent
observations, new experiments, case studies, or novel concepts. We
encourage submissions from different communities, approaches and
applications to foster discussions and exchange ideas that also
include negative results or failed approaches. We welcome all
contributions regarding the strength, stress state and strain field
in the crust whether from spatial scales of wells, reservoir or up
to the entire crust and covering different time scales from
individual earthquakes to multiple earthquake cycles.
