Fig. 2: Regional GLOF rate and local glacier thickness and length compared with the size of burst lakes.
From: Progressively smaller glacier lake outburst floods despite worldwide growth in lake area
a, Average number of reported GLOFs per year in the 13 study regions versus regional pre-GLOF lake area. Points represent the median and lines span the 25th to 75th percentiles of pre-GLOF lake areas in regions that had more than five GLOFs per dam type (n = 1,671). Patagonia is the region with the largest pre-GLOF lake area and the Coast Ranges had the highest reporting rate. b, Estimated average thickness of parent glaciers39 versus pre-GLOF lake area. For lakes with repeated outbursts, we show only the largest pre-GLOF lake area per site (n = 255). c, Length of the parent glacier40 versus pre-GLOF lake area (n = 255). The marginal boxplots show the median (thick line), interquartile range (box) and 1.5 times the interquartile range (whiskers) for a given sample, distinguished by dam type. The colour code in a also relates to b and c.
