What is the chance of another catastrophic volcanic eruption at Yellowstone?

  • Although another catastrophic eruption at Yellowstone is possible, scientists are not convinced that one will ever happen.
  • If Yellowstone does erupt again, it need not be a large eruption. The most recent volcanic eruption at Yellowstone was a lava flow that occurred 70,000 years ago.
  • Most volcanic systems that have a supereruption do not have them multiple times.
  • When supereruptions do occur more than once in a volcanic system, they are not evenly spaced in time.
  • It is not valid to calculate a recurrence period using only two values (the two intervals between Yellowstone’s supereruptions). So stating that Yellowstone is some number of years overdue for a supereruption is mathematically inaccurate.
