Focal mechanism maps for the Northern Alps-Jura-Vosges region. Symbols as in Figure 4. (a) Stereographic projections (lower hemisphere) of focal mechanisms. (b) Grid average faulting style. (c) Grid-average orientations of near-horizontal P axes. (d) Principal axes of horizontal strain rates from smoothed GNSS data (Masson et al., 2019). Orange bars in (c) show in-situ maximum horizontal compressive stress orientations (Paquin et al., 1978). Thin black lines in (a)–(d) show geological and potentially active faults (Baize et al., 2013; Jomard et al., 2017). White dashed ellipses in (a)–(d) show specific areas discussed in the text.
