This is for the survivalist types who think planning for a Yellowstone or other supervolcano eruption is a good use of their time.
Super Volcano Will Challenge Civilization, Geologists Warn | LiveScience
""An area the size of North America can be devastated, and pronounced deterioration of global climate would be expected for a few years following the eruption," Self said. "They could result in the devastation of world agriculture, severe disruption of food supplies, and mass starvation. These effects could be sufficiently severe to threaten the fabric of civilization.

Geologists in the United States detailed a similar scenario in 2001, when they found evidence suggesting volcanic activity in Yellowstone National Park will eventually lead to a colossal eruption. Half the United States will be covered in ash up to 3 feet (1 meter) deep, according to a study published in the journal Earth and Planetary Science Letters.
Explosions of this magnitude "happen about every 600,000 years at Yellowstone," says Chuck Wicks of the U.S. Geological Survey, who has studied the possibilities in separate work. "And it's been about 620,000 years since the last super explosive eruption there."
...
Unlike other things, there's nothing to be done about an imminent volcanic eruption. Drilling a hole 'to relieve pressure' is simply creating a means for that pressure to escape explosively, thus creating the eruption you were trying to prevent.
Vesuvius in Italy is a current worry for regular explosive eruption (not supervolcano size.) In past eruptions a plug in the top of the cone formed trapped magma and pressure to build until a fault appeared setting it off. Since it's last major period of activity a new plug has formed and pressure is once again building up.
Yellowstone's supervolcano is also a growing concern showing many of the signs we attribute to an imminent eruption as with grown deformation (rising ground because of rising magma underneath,) and small earthquake 'swarms.' And given it's past eruption history, it's long overdo for a super-eruption.
It's natural to try and survive life-threatening events. But in some situations survival may not be the desired outcome as if the entire planet is under threat as it'd be after a supervolcanic eruption.
"But it's all right. I've planned ahead. We're just 2 miles from a primary target. A millisecond of blinding light, and we're vaporized. Much better than the millions who'd survive to wander sightless through the smoldering aftermath. We'll be spared the horror of survival." - "Wargames"
