Nearly 1500 stress orientation determinations are now available for Europe. The data come from earthquake focal mechanisms, overcoring measurements, well bore breakouts, hydraulic fracturing and young fault slip studies sample the field surface to seismogenic depths. Three distinct regional patterns of maximum compressive horizontal ( S Hmax ) can be defined these data: a consistent NW NNW in western Europe; WNW‐ESE Scandinavia, similar Europe but with larger variability orientations; E‐W...
The World Stress Map Project compiles a global database of contemporary tectonic stress information the Earth's crust. Early releases demonstrated existence first‐order (plate‐scale) fields controlled by plate boundary forces and second‐order (regional) major intraplate sources such as mountain belts zones widespread glacial rebound. 2005 release provides, for some areas, high data density that enables us to investigate third‐order (local) field variations, controlling them active faults,...
Abstract Tectonic stress is one of the fundamental data sets in Earth sciences comparable with topography, gravity, heat flow and others. The importance observations for both academic research (e.g. geodynamics, plate tectonics) applied hydrocarbon production, civil engineering) proves necessity a project like World Stress Map compiling making available on global scale. offers not only free access to this database via Internet, but also continues its effort expand improve database, develop...
Slab break‐off is a plate‐tectonic process which does not only return lithospheric material into the deeper mantle, but also has severe effects on surface movements and seismic hazard: slab‐pull induced seismicity reduced when subducted slab decouples from overlying crust. In Vrancea region (SE Carpathians), strong earthquakes frequently occur at intermediate depths (70–180 km) in laterally small volume, while crust shows low distributed seismicity. The stress pattern similar partitioning...
Knowledge of the present-day tectonic stress is essential for numerous applications in petroleum exploration and production civil mining engineering, such as improving stability boreholes tunnels enhancing through natural or induced fractures. The World Stress Map (WSM) Project a collaborative project between academia, industry, government that building comprehensive global database information to better understand state sources contemporary lithosphere (Figure 1).
Abstract Knowledge of the crustal stress state is important for assessment subsurface stability. In particular, magnitudes are essential calibration geomechanical models that estimate a continuous description 3-D field from pointwise and incomplete data. Well established World Stress Map Project, global publicly available database orientations, but magnitude data only local collections available. Herein, we present first comprehensive open-access Germany adjacent regions, consisting 568...
A robust prediction of the present-day stress state is great importance for safe usage subsurface, e.g., borehole stability, mitigation induced seismicity or search and long-term safety a high-level nuclear waste deposit. However, knowledge concerning in Germany limited as only unevenly distributed measurements are available. Two 3D geomechanical-numerical models created during SpannEnD project (2018-2022) have improved this level knowledge. Such - calibrated on available magnitudes enable...
Faults are an important factor for geoenergy applications due to either their sealing or conducting properties mechanical behaviour. Consequently, (thermo-hydro-) numerical investigation of often include faults in modelled rock volume. It is assumed, that can significantly alter the far-field stresses, impacting both magnitudes and orientation. In contrast far-field, stress rotations vicinity clearly observed numerous borehole analyses across world. While impact on field expected,...
Abstract Recent (active) tectonics of the Pannonian Basin and its surroundings has been investigated using data from over 900 earthquake focal mechanism solutions, 200 borehole breakout analyses, some in-situ stress measurements by applying finite element modelling technique. We have established a database for indicators recent stress, analysed state region methods World Stress Map project. The alignments largest horizontal stresses mapped tectonic regimes were also determined. present map...
We model microseismicity triggered by fluid injection on the basis of theory poroelasticity accounting for external stress field. Consideration fully coupled poroelastic field equations enables us to apply a Coulomb failure criterion using pore pressure and tensor as well coefficient friction. The fields are calculated with finite-element method simulating constant rate into 2-D domain. influence diffusivity, occurrence is analysed compared simulations based diffusion only. show that an...
Abstract. The contemporary stress state in the upper crust is of great interest for geotechnical applications and basic research alike. However, our knowledge crustal field from data perspective limited. For Germany basically two datasets are available: orientations maximum horizontal (SHmax) regime as part World Stress Map (WSM) database well a complementary compilation magnitude adjacent regions. these only provide pointwise, incomplete heterogeneous information 3D tensor. Here, we present...
