What the study found
NW/SE- and NNW/SSE-oriented faults near the selected study area showed higher slip tendency, meaning they were assessed as more susceptible to reactivation. The authors also identified some faults with both above-average slip tendency and potential moment magnitude.
Why the authors say this matters
The study suggests this information is relevant for understanding fault reactivation and induced seismicity, which the authors link to underground CO2 storage operations. The findings also indicate that critical focal mechanisms are important for further wave propagation simulation.
What the researchers tested
The researchers studied a potential CO2 storage site in the Middle Buntsandstein sandstone formation on the West Schleswig Block in the German North Sea. They built a 3D fault dataset from roughly 80 2D seismic lines and used present-day stress tensors from spatial interpolation of a 3D numerical stress model of Germany to perform slip-tendency analysis. They also estimated a sustainable pore pressure window and potential moment magnitude if reactivation occurs.
What worked and what didn't
The fault dataset and stress-based analysis identified fault orientations with higher slip tendency, especially NW/SE and NNW/SSE trends. The study further found faults that combined above-average slip tendency with potential moment magnitude, and these were discussed. The abstract does not report any faults that were ruled out in detail.
What to keep in mind
The available summary does not describe the full limitations of the study. The work focuses on one selected study area and on existing faults in its vicinity, so the results are scoped to that setting.
