Depth distribution of data records. The bars of the histograms are colour coded according to the type of stress magnitude indicator. The inset plots show the upper 500 m and 50 m below surface, respectively, in more detail and clarify the clustered appearance of the borehole slotting and overcoring measurements in shallow depths. The colour code corresponds to that used in Figs. 5a and 7. Percentages reflect the overall proportions of the different stress magnitude indicators. Considered are all data records for which depth information is available (n = 564). 273 data records are included in the larger inset histogram, 116 data records are included in the smaller inset histogram
