Regionalization of the deformation in the northern Jura FTB (S parameter, based on the rake angle, see text) for two different depth intervals within the upper crust. a Uppermost crust (0–5 km). b Upper to mid-crustal depths (5–15 km). The colour code corresponds to the type of deformation (compression in red, extension in blue, strike-slip in white). Circles are observed focal mechanism (FM) color-coded according to the S values, same as the interpolated grid in the background. The orientation of T-axes for extensional and the orientation of the P-axes for compressional focal mechanisms are also shown with blue and red lines, respectively
