Fig. 2: Shifts in rockfall seasonality over time, with activity occurring progressively later in the year.
From: Rockfall from an increasingly unstable mountain slope driven by climate warming
a, Sub-seasonal frequency of occurrence (inset) and Monte Carlo (MC) modelled day of year (doy) of rockfall from 1920 to 2020. The MC approach models a box plot for the seasonal occurrence of each injury (circles) and GD (rectangles), thereby considering uncertainties in actual rockfall dates. Local polynomial regressions are shown with blue (injuries; n = 83) and red (GD; n = 408) lines and 95% confidence intervals. b,c, Tail probabilities for annual shifts in rockfall seasonality for GDs (b) and injuries (c) only. Damage in trees is given as D = dormancy (white); EE = early early wood (light grey); ME = mid-early wood (grey); LE = late early wood (dark grey); EL = early latewood (yellow) and LL = late latewood (red).
