The World Stress Map project provides the only open-access database of crustal stress information. The new global database has been substantially updated, and now contains more than twice the number of data on the orientation of maximum horizontal stress (SHmax). As data are clustered, we provide mean SHmax orientations on different global grids. The results reveal for intraplate areas that the earlier hypothesis that plate boundary forces control the SHmax orientation needs to be revised.

We assess the fault impact on the stress field in northern Switzerland using 3D geomechanical models, calibrated with stress data. We see that faults affect the stresses only locally, with negligible impact beyond 1 km, suggesting that faults may not be necessary in reservoir-scale models predicting stresses of undisturbed rock volumes, such as for a geological repository. Omitting them can substantially reduce model set-up time and computational cost without compromising prediction reliability.

Understanding the stress and strain conditions in the Earth's crust is crucial for various activities, such as oil and gas exploration and assessing seismic hazards. In this article, we have updated the database of moment tensor focal mechanisms for Greater Iberia. We conducted kinematic and dynamic analyses on the selected populations, determining the average focal mechanism, strain and stress orientations, and tectonic regime. The orientation for horizontal compression is primarily N154° E.

Obtaining reliable estimates of the subsurface state distributions is essential to determine the location of, e.g., potential nuclear waste disposal sites. However, providing these is challenging since it requires solving the problem numerous times, yielding high computational cost. To overcome this, we use a physics-based machine learning method to construct surrogate models. We demonstrate how it produces physics-preserving predictions, which differentiates it from purely data-driven approaches.

The study explores the potential for storing carbon-rich products in Germany to support climate goals. Using geological data, we identified old mining sites suitable for storing products like graphite and oxalate from negative emissions technologies. Results show significant storage potential, both above and below ground, offering a sustainable solution. By reusing existing mining areas, Germany can advance towards carbon neutrality, reducing costs and environmental impact.

The rotation of the principal stress axes in a fault structure because of a rock stiffness contrast has been investigated for the impact of the ratio of principal stresses, the angle between principal stress axes and fault strike, and the ratio of the rock stiffness contrast. A generic 2D geomechanical model is employed for the systematic investigation of the parameter space.

It is generally assumed that faults have an influence on the stress state of the Earth’s crust. It is questionable whether this influence is still present far away from a fault. Simple numerical models were used to investigate the extent of the influence of faults on the stress state. Several models with different fault representations were investigated. The stress fluctuations further away from the fault (> 1 km) are very small.

Short summary
In numerical geomechanical models, an initial stress state is established before displacement boundary conditions are applied in order to match calibration data. We present generic models to show that the choice of initial stress and boundary conditions affects the final state of stress in areas of the model domain where no stress data for calibration are available. These deviations are largest in the vicinity of lithological interfaces, and they can be reduced if more stress data exist.

The recent crustal stress state is a crucial parameter in the search for a high-level nuclear waste repository. We present results of a 3D geomechanical numerical model that improves the state of knowledge by providing a continuum-mechanics-based prediction of the recent crustal stress field in Germany. The model results can be used, for example, for the calculation of fracture potential, for slip tendency analyses or as boundary conditions for smaller local models.

Stress data predicted by a geomechanical–numerical model are mapped onto 3D fault geometries. Then the slip tendency of these faults is calculated as a measure of their reactivation potential. Characteristics of the faults and the state of stress are identified that lead to a high fault reactivation potential. An overall high reactivation potential is observed in the Upper Rhine Graben area, whereas the reactivation potential is quite low in the Molasse Basin.

Short summary
Numerical methods can be used to estimate the stress state in the Earth’s upper crust. Measured stress data are needed for model calibration. High-quality stress data are available for the calibration of models for possible radioactive waste repositories in Switzerland. A best-fit model predicts the stress state for each point within the model volume. In this study, variable rock properties are used to predict the potential stress variations due to inhomogeneous rock properties.

Short summary
The subsurface is subject to constant stress. With increasing depth, more rock overlies an area, thereby increasing the stress. There is also constant stress from the sides. Knowledge of this stress is fundamental to build lasting and safe underground structures. Very few data on the stress state are available; thus, computer models are used to predict this parameter. We present a method to improve the quality of the computer models, even if no direct data on the stress state are available.

When stresses yield a critical value, rock breaks and generate pathways for fluid migration. Thus, the contemporary undisturbed stress state is a key parameter for assessing the stability of deep geological repositories. In this workshop you can ask everything you always wanted to know about stress (but were afraid to ask), and this is divided into three parts. 1) How do we formally describe the stress field? 2) How do we to actually measure stress? 3) How do we go from points to 3D description?

In this study, we investigate the evolution of fault reactivation potential in the greater Ruhr region (Germany) in respect to a future utilization of deep geothermal resources. We use analytical and numerical approaches to understand the initial stress conditions on faults as well as their evolution in space and time during geothermal fluid production. Using results from our analyses, we can localize areas more favorable for geothermal energy use based on fault reactivation potential.

Short summary
Reactivation of tectonic faults can lead to earthquakes and jeopardize underground operations. The reactivation potential is linked to fault properties and the tectonic stress field. We create 3D geometries for major faults in Germany and use stress data from a 3D geomechanical–numerical model to calculate their reactivation potential and compare it to seismic events. The reactivation potential in general is highest for NNE–SSW- and NW–SE-striking faults and strongly depends on the fault dip.

Short summary
The Earth's crust is subject to constant stress which is manifested by earthquakes at plate boundaries. This stress is not only at plate boundaries but everywhere in the crust. A profound knowledge of the magnitude and orientation of the stress is important to select and build a safe deep geological repository for nuclear waste. We demonstrate how to build computer models of the stress state and show how to deal with the associated uncertainties.

Knowledge of the crustal stress state is important for the assessment of subsurface stability. In particular, stress magnitudes are essential for the calibration of geomechanical models that estimate a continuous description of the 3-D stress field from pointwise and incomplete stress data. We present the first comprehensive and open-access stress magnitude database for Germany, consisting of 568 data records. We introduce a quality ranking scheme for stress magnitude data for the first time.

Short summary
A numerical model integrating the structure and mechanical properties of a sedimentary sequence in the Alpine foreland is presented to show that topography, tectonic faults and, most of all, spatialy variable rock properties affect the state of stress at depth. The tectonic forces acting on the sequence are primarily taken up by the stiff rock units leaving the weaker units in a stress shadow.
