Here's a fun figure I made:

every volcano on the planet, colored by every known eruption.

This data comes courtesy of the Smithsonian Institute's Global Volcanism Program.

This dataset includes 10734 known eruptions from 1562 individual volcanoes, going back about 12000 years! Of course the data are not complete throughout history, but should be quite robust for modern times.

For reference, there are 176 entries for eruptions since 2010!!

Our planet is incredible...
