[Geoqus] EGU session on geomechanics - strength and stress

[Moritz Ziegler]

Dear colleagues,

we'd like to draw your attention to our session in the upcoming EGU 
titled: *"Stability of the crust - strength and stress make it"*

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.

More details and abstract submission can be found here: 
https://meetingorganizer.copernicus.org/EGU24/session/48655 Please note 
the EGU-wide abstract submission deadline on *January 10th 12:00 CEST*.

Please help us spread the word and forward this call for contributions 
to colleagues that might be interested.

Looking forward to see you in Vienna,

Moritz Ziegler, Gian Maria Bocchini, Armin Dielforder, Patricia 
Martínez-Garzón, Karsten Reiter

Stability of the crust – strength and stress make it

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.
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.
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.
