Fig. 1: Revised global inventory of moraine-dammed GLOFs and their spatial distribution.
From: High frequency of moraine-dammed lake outburst floods driven by global warming
a The maps show the global distribution, local number, and relative densities of GLOFs during 1900–2020. The circles are scaled according to the number of GLOFs within each 1° × 1° tile and are color-coded to indicate the proportion of locally drained lakes relative to the total. The pie charts aggregate the regional GLOF count based on the Global Terrestrial Network for Glaciers (GTN-G) regions, and display their respective data sources, including the latest global inventory v4.0 (Inventory), supplementary data from other reports (Additional), and the newly detected events identified via geomorphic assessments in this study (Detected). The distribution data for glacial lakes in 2020 is sourced from Zhang et al.20. b A linear fit for annual GLOF frequency was performed using the generalized additive model. The degrees of freedom (edf) and chi-square statistic (χ2) indicate the complexity and goodness of fit, with lower values suggesting a better model. The p-value for the mean slope (Pslope) reflects the significance of the trend. Map source: Natural Earth (public domain).
