From: Rock glaciers throughout the French Alps accelerated and destabilised since 1990 as air temperatures increased

Fig. 4: Rock glacier displacement rates evolution.

Evolution of the rock glacier displacement rates in the French Alps in the three periods investigated and grouped by destabilisation rate. The symbol size is proportional to the measured displacement rate, while the symbol colour is assigned according to the destabilisation rate (see Fig. 3 for rate description). The boxplot respect the standardized sizes: the interquartile (IQR) range groups observations from the 25th (Q1) to 75th (Q3) percentile, while the whiskers represent the maximum (Q3 + 1.5*IQR) and minimum (Q1−1.5*IQR). © IGN.
