Working Group Analysis and Modelling of Crustal Stress

Modern civilisation explores and penetrates the Earth’s crust, recovers from it and stores into it fluids and gases to a hitherto unprecedented degree. The contemporary crustal stress state is a key parameter for a wide range of technological problems such geothermal reservoir management as well as for the site selection process for a deep geological repository for radioactive waste. Furthermore, the stress evolution during the seismic cycle is one of the key processes that control the nucleation, rupture propagation and arrest of a seismic event. Thus, our ultimate goal is to quantify the in situ stress state and its spatio-temporal variability as well as and the failure due to natural and induced processes.

The key challenge is to derive from point-wise stress information in the crust derived from a wide range of stress indicator a continuous description across different scales from boreholes to plate-wide regions. To achieve this we analyse stress data and use these to calibrate 4D thermo-hydro-mechanical-dynamic (THM-D) models. Our long-term goal is to link the results of these deterministic models with the statistical methods to achieve in specific settings a physics-based probabilistic seismic hazard assessment.

a.
Stress data in Northern Swit­zer­­land. Lines show the orientation of maximum horizontal stress SHmax. Yellow square denotes the model area. Colors in the model volume show the differences between the maximum and the minimum horizontal stress SHmax-Shmin and the discretization into finite elements. White line denotes the cross section shown in Fig b.

b. Lithology sequence that is implemented in the 3D geological model (Hergert et al., 2015) and model results in terms of the difference of horizontal stresses SHmax-Shmin.

c. Displayed are the magnitudes SV, SHmax and Shmin along a vertical line (white line in figure c) with SV the vertical stress. Red symbols denote data of Shmin magnitudes derived from hydraulic fracturing measurements.
