Fig. 3: Rockfall events and statistical analysis of controlling factors.
From: Alpine rockwall erosion patterns follow elevation-dependent climate trajectories
a Rockfall frequency-magnitude distribution for individual periods (2016–17 in yellow, 2017–18 in red, 2018–19 in green) and for the entire 2016–2019 period (in grey) in the Hungerli Valley. Linear correlation r2 of power laws is between 0.98 and 0.99 with p < 0.001. b PCA of rockfall variance between five variables: deglaciation age (i.e. proxy for paraglacial condition, elevation (proxy for frost cracking), MARST (proxy for permafrost), slope angle, and rockfall volume.
