In the course of the SpannEnD project (), a 3D stress model was created for Germany for the first time, taking into account published structural models and geomechanical data, and calibrated to measured data records on stress magnitudes and orientations. Based on a new geological 3D model of Germany (Ahlers & Henk 2025) a new geomechanical model has been created whose publication is in preparation. Due to the improved geological model, twice as many units – in comparison to the former model – are resolved in the new geomechanical model. In addition, a five-time higher vertical resolution is used and the number of stress magnitude data records used for calibration could be tripled. The video shows an example of the predicted stresses of the maximum horizontal stress (SHmax) from the uppermost 5 km in the central part of the geomechanical model. www.spannend-projekt.de/en
Status Quo & Outlook
The project is in its final year. Initial results are currently being prepared for publication.
