Correlation between gas discharges and tectonic regimes. Box plots of calculated p values and Spearman’s rank correlation coefficients between gas discharges and a, b faults lengths of different slip types and c, d different tectonic stress regimes. Upper and lower whiskers are maximum and minimum values. Horizontal gray stripe in (b, d) shows the 95% confidence interval (the null hypothesis of no correlation is rejected if p value < 0.05). Box colors denote the eight hexagonal grids used for the calculations, from the greatest (red, resolution 2) to the smallest (pink, resolution 9) hexagonal cell
