The number of eruptions over time for glaciated and non-glaciated regions. Number of eruptions over time for (a) the global dataset from 1 to 50 ka, showing a peak in activity at ~10 ka; (b) a detailed view of the period 5 to 15 ka encompassing this peak, showing eruptions in regions which were glaciated during the Last Glacial Maximum (LGM); and (c) the period 5 to 15 ka in non-glaciated regions. A moving average trendline is applied to all graphs to reduce noise (black line) and the number of eruptions is calculated in 100 year bins.
