Map of notable volcanic eruptions. The apparent volume of each bubbles is linearly proportional to the volume of tephra ejected (i.e. their radius is linearly proportional to the cube root of the volume of tephra ejected), colour-coded by time of eruption as in the legend. Pink lines denote convergent boundaries, blue lines denote divergent boundaries and yellow spots denote hotspots. The dashed circle shows the equivalent ejection from the Chicxulub impact (200000+ km³).[1] The background map is extracted from https://earthquake.usgs.gov/learn/topics/plate_tectonics/majplatecolor.pdf and http://oceanexplorer.noaa.gov/okeanos/explorations/ex1103/logs/hires/hotspots_map_hires.jpg . |
