Fig. 4From: Regional and global under-recording of large explosive eruptions in the last 1000 yearsRecording probabilities by region. The two polygons show pointwise 95 and 50% credible regions, and the solid line shows the maximum a posteriori estimate (see the Appendix for details of how this is calculated). The times of recorded large eruptions are shown as ticks on the horizontal axis. Only regions with at least 10 recorded large eruptions are shownBack to article page
