Overview of the geology of the model region and stress data used for comparison and calibration. The black frame shows the key area of the model with increased stratigraphic resolution based on Anikiev et al. (2019). a Distribution of the stress magnitude data of Morawietz and Reiter (2020). The color-coded dots indicate the quality assigned by Morawietz et al. (2020). Displayed are all data from a true vertical depth (TVD) > 200 m. b Data of the World Stress Map (WSM) of Heidbach et al. (2016) and Levi et al. (2019). Color-coded lines indicate the stress regime and the orientation of S_Hmax. Grey lines show the mean orientation of S_Hmax on a regular grid (Details see chapter 3.1). c Geological framework of the model area based on Asch (2005) and Kley and Voigt (2008). BF—Black Forest, CG—Central Graben, EI—Eifel, HG—Horn Graben, HZ—Harz Mountains, GG—Glückstadt Graben, LRG—Lower Rhine Graben, OD—Odenwald, OG—Ohře Graben, SNB—Saar–Nahe Basin, SP—Spessart, TW—Tauern Window, URG—Upper Rhine Graben, VB—Vogelsberg Complex, VG—Vosges. d Overview of the basement structures based on Kroner et al. (2010) and Brückl et al. (2010). The red frame shows the entire model area. ALCAPA—Alps–Carpathian–Pannonian, ATA—Armorican Terrane Assemblage, EEC—East European Craton
