Verdant Skies was partly inspired by data on the Yellowstone Caldera, the buried supervolcano in the Wyoming-Idaho-Montana area which,
if when it erupts, could create an ecological disaster akin to the process which accelerated the end of the Dinosaurs.
Now University of Utah seismologists have discovered even more detail about the caldera, including a magna pocket below the known pocket and five times larger. No, it doesn’t make the threat of an eruption more imminent; but it does mean that an eruption could be much, much worse than previously assumed. See more at the link.
