Researchers: Global Risk of Supervolcano Eruption Greater Than Previously Though

rbrandis writes "The eruption of a 'supervolcano' hundreds of times more powerful than conventional volcanoes – with the potential to wipe out civilization as we know it – is more likely than previously thought, a study has found. An analysis of the molten rock within the dormant supervolcano beneath Yellowstone National Park in the United States has revealed that an eruption is possible without any external trigger, scientists said."

Re:Priorities

[maverickgunn]

In this case, "likeliest" is a subjective term, since there are so many factors at play and it's difficult if not impossible at this point to try to predict what roaming variable will arise that will push the volcano over the tipping point. The best we can do is compare previous events with current factors, but even then our predictions will fall further on the guessing side of the line.

So, on a serious basis, I think a higher priority at this point should be placed on developing ways to protect ourselves from an imminent disaster like that relative to the size of that potential disaster. Worst case scenario, we need to pursue solutions which involve leaving the planet entirely if it is rendered uninhabitable for a period long enough to exterminate us.

It's been proposed. Supercomputer simulations show that attempting to poke in a relief valve would give the existing pressure a channel to explode though with full force. Just because super volcanoes may not require a trigger does not mean that one cannot be triggered.
