There’s no (reasonable,) conceivable way to stop a super volcano. The technology and manpower required would be so absolutely massive it’d be cheaper to just build 6 or so billion habitation modules on the moon for a few decades, let the dust clear (literally) and come back later. By the time we reach a technological level to diffuse something like Yellowstone, things like Yellowstone won’t need diffusing (for the survival of the human race).
We’re already capable of maintaining small populations in secure centers, there’s no reason 500-1000 people in multiple areas couldn’t stage bunker down and live through the eruption, and that’s likely what would happen, along with individual survivors. Humans are tough, we’re like lice – you only need one in a million to survive, and you still have 6000 survivors, more than enough to repopulate the planet. Now, whether those six thousand or so would be able to find each other would be another matter.
Survivors might be limited to certain areas (say, a few dozen in DC, a few dozen in Mumbai, etc), which would make things significantly more difficult, but not impossible.
And if we can get by without an extinction level event for the next few centuries, we’ll likely have (I really hope we’ll have, at least) the technology to live in closed systems, or at least mostly closed systems. And if you can get a closed enough system, you can live in space, or pretty much anywhere.
Last I checked the prevailing winds blow west to east. The 1980 eruption of Mount St. Helens offers some good background on ash dispersal and wind patterns. Just shift the ash patterns from the 1980 eruption to Yellowstone as an example. Of course, the eruptive potential of Yellowstone is on a scale far beyond that of Mount St. Helens and actual blast effects could pretty much take out a significant amount of North America.
The 1980 Mount St. Helens eruption on the Volcanic Explosivity Index (VEI) rates a 5. The 1991 Mt. Pinatubo eruption rates a 6. The Yellowstone eruptions are estimated to have been an 8. Keep in mind, the scale is logarithmic, with each interval on the scale representing a tenfold increase in observed eruption criteria.
Consider this from the 1991 eruption of Mount Pinatubo:
I don’t think that’s true at all given the pace knowledge and technology are advancing. I can conceive of a way right now – map the core and mantle of the earth, measure the pressures of the magma pools, and release the dangerous pressures in non-catastrophic ways.
I dunno HOW to map, measure, or bleed off the pressure, but I don’t see any reason we won’t develop the technology to do so. Maybe in a couple of hundred years, maybe sooner or maybe later. But I’d bet we’ll have that technology sooner than say, a hundred thousand years. Well, I’d bet if I was gonna be alive ling enough to either pay or collect on the bet.
Right, but is that technology reasonable?
For instance; while we might be able to theoretically do that with unfathomably expensive (by our standards) technology, with equally (or perhaps less) unfathomably expensive technology, we could relocate everyone on Earth – would it cost less to drastically, dynamically and persistently alter the geology of the Earth, or move humanity to the moon?
ETA: Also, not really a “conceivable way,” really more of a “just maybe we might be able to kind of do something to fix it.” (I don’t say that insultingly, I just can’t think of a better way to phrase it.)
I dunno what it will cost either, but another bet I’d make (if possible) is that it won’t be as expensive as the cost of destroying the surface environment of the Earth. Or as pricey as constructing a new environment elsewhere for the entire population of the earth and then moving the entire population to the new place.
There are already vents in Yellowstone park. If there was any indication of a massive rise in the landscape we could just set up automated drilling rigs in conjunction with the vents.
You wouldn’t have to move the entire population, I mean, you’d have to move quite a few of them, if not to space than at least around the Earth. You’d definitely need to build new structures, or at least some way of protecting the current structures.
I don’t think you could, in fact.
It’s not like drilling for oil. Drilling for oil is easy, by comparison. The depths and pressures, and size, of the caldera is ridiculously beyond anything we have the ability to deal with. It’s not like tapping a keg.
It might be exactly like tapping a keg, or controlling a huge steam engine with pressure relief valves. Or maybe we will be able to draw off the heat for energy with some form of geothermal tap, and the loss of heat will lessen the pressure.
Honestly, among all the potential environmental threats to humankind, this seems not nearly as big a threat as some others, though maybe more likely to happen sooner.
Cute story - The part that made me laugh was the assertion that governments from around the world would chip in to avoid the disaster.
The likelier reality would be a bunch of partisan bickering until the damned thing blew, and the last broadcasts of human kind would show one political party or another saying “well, we didn’t have reasonable proof at the time”.
I think it’s as big a threat and its one of the more difficult to tackle. We’ve been to space, we’ve launched objects large enough to use as a gravity tug on a celestial body, at least with enough time. On the other hand, we don’t have an even “in theory” technology for drilling deep enough to tap that keg.
There are some practical problems with trying to drill a volcano. How do you keep your drill equipment from melting, or at least overheating? Volcanoes also have a habit of doing things like creating rivers of molten rock and pools of boiling water, which make a hazardous environment for any kind of construction work. Yellowstone in particular is a hazardous place to go walking around, if you don’t stay on the paths. There is sometimes thin ground that a person walking can break through and fall into boiling water or mud. What do you think is going to happen if someone tries to bring heavy drilling equipment into an area like that?
There are some legal problems, too. What if we drill, the volcano goes off, and some geologists think that the drilling might have triggered the eruption? Can the people who did the drilling be sued? Or, alternatively, we don’t drill, and the volcano erupts. Can the people who could have drilled but didn’t be sued for negligence?
Not only that, but say you do drill a series of holes large enough to make a difference in the pressure, somehow, and that the equipment didn’t melt on the way down, and you constructed some amazing new material that didn’t collapse under the ridiculous pressure that the earth puts on empty spaces that deep, how do you keep the molten rock molten, and flowing? If it hardens up – as molten rock is prone to doing – it’s just going to clog up and you’ll have to drill an entirely new hole, having relieved almost no pressure.
There just isn’t a clear cut, simple solution to delaying, much less stopping, an eruption of this magnitude. Hell, there might not even be a solution at all. Yellowstone is caused by a thin bit of crust (a hotspot), the same way Hawaii is. You’re not talking about poking a hole in a soda can, you’re talking about literally altering the crust and possibly even the mantle of the earth.
ETA: now that I think about it, it might just be easier to construct a huge dome over yellowstone, let it erupt and then deconstruct the dome than trying to stop yellowstone. It’s certainly more feasible at this point.
