Global map of obscured earthquake risk, plotted with a Robinson projection. (a) Population at risk of earthquake impacts in colour overlain in dark grey with locations where the probability of >3 consecutive days cloud cover exceeds 50% in ≤1 month of the year. Areas obscured in >1 month of the year are left lighter to highlight the underlying earthquake risk in these regions. (b–e) More detailed views of Central America and northern South America (b), the Himalaya and surrounding regions (c), Indonesia and Papua New Guinea (d) and Japan, Taiwan and the Philippines (e). (f) Monthly variation in total global obscured population at risk showing median (red) and median ± one standard deviation (dark grey).
