Stress fields estimated in this study. Stress axis orientations and R-values estimated for the entire study area (a), in 1-km depth slices (b–f) and in 3-km depth slices (g, h) are shown. Principal stress axis orientations and 95% confidence intervals are projected onto lower hemisphere equal-area projections. Red, green, and blue circles correspond to the σ₁, σ₂, and σ₃ axes, respectively. Background color of “shallower strike-slip fault-type” and “deeper reverse fault-type stress” indicates fault type; the same color scheme is used throughout this study
