The risk of supervolcanos looks higher than previously thought, though none are imminent.
Is there anything conceivable which can be done to ameliorate the risk?
The only suggestion I've heard is self-sustaining space colonies, which obviously is not doable anytime soon. Depending on the specifics, buried bunkers might work, as long as they're not on the same continent to be buried in the ash or lava.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
