Extended Data Fig. 3: Evolution over time of tree diameters, sample depth and length equivalent to the slope width sampled.
From: Rockfall from an increasingly unstable mountain slope driven by climate warming
(a) Changes in the cumulated sum of all tree diameter (in m), (b) number of trees in the chronology (sample depth) and the length equivalent to the slope width (177 m) that was sampled (in %) for every year between 1920 and 2020. (c) Raw numbers of rockfall impacts (injuries or GD) are corrected following the conditional impact probability (CIP) approach, resulting in the inclusion of more events in the chronology for years in which only part of the slope width is covered and in a reduction of events whenever the sum of diameters exceeds the slope width (177 m). The years 1937 and 1995 are selected here to illustrate the conversion.
