Evidence Suggests Updated Timeline Towards Yellowstone's Supervolcano Eruption (nytimes.com) 320
Camel Pilot writes: Geologist have been aware of fresh magma moving in the Yellowstone's super volcano system. Previously this was thought to precede an eruption by thousands of years. Recent evidence by Hannah Shamloo, a graduate student at Arizona State University, demonstrates that perhaps the timeline from the underground basin filling to eruption is more on the scale of decades. A super volcano eruption has the power to alter life's story on this earth and even destroy all life on a continent. In light of this, it seems like a good time to invest some effort and resources into finding ways to prepare, delay or deflect the potential threat. The research was presented at the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) 2017 conference in Portland, Oregon.

Two approaches come to mind, both of which are probably too massive to actually be undertaken. One is to cool the magma, by drilling a grid of holes and pumping water into them. (Use the heated water or steam for electric power plants.) The other is to break up the surface to a depth of several miles (underground nuclear bombs), so that any eruption will be just magma flows rather than an explosion.
Could either work? I don't even pretend to know. Would either attempt cause more problems than it solved? I wouldn't be surprised. At least some examination of possibilities should be done.

I certainly hope you forgot your </sarcasm> tag there, since given the choice between "Yellowstone is an uninhabitable crater" and "Yellowstone is the caldera of the supervolcano that destroyed humanity", I'm going to go out on a limb and suggest that the former option—the one where humans still exist—would be better for tourism.
Last I had heard, they were estimating that an eruption of the Yellowstone supervolcano could result in 10 feet (i.e. 3 m) of ash being deposited in Houston. Even without considering the life-ending clouds that would cover the earth for decades, that much ash on the ground would be more than enough to end a civilization for the simple reasons that you wouldn't be able to breathe, move about, or work the land.
Now, for folks who aren't intimately familiar with US geography, this may sound like yet another tragedy for the people of Houston after the recent hurricane that ravaged the city, but that's missing the point entirely. The point here is that Houston is nowhere close to Yellowstone. Nowhere close.
To put it in perspective for any Europeans, the distance from Yellowstone to Houston (i.e. ~1300 miles or ~2100 km as the crow flies) is roughly the same as the distance from Amsterdam to Moscow (or London to Bucharest or Paris to Istanbul). Another way of putting it is that if an eruption of this magnitude happened in Munich, you'd have to travel to the Arctic Circle, the middle of the Sahara, or somewhere beyond Moscow before you'd see less ash than what I described. For any Aussies, it'd mean that if an eruption happened in Alice Springs, the entire country would be under that much ash or more. You'd have to get pretty far into Papua New Guinea or Indonesia before you'd see any less than I described.
All of which is to say, we're talking about life-ending amounts of ash being deposited across entire continents, so preventative measures may be necessary if we want there to be tourism, not just in Yellowstone, but anywhere on the planet.

There really is no difference. The problem here is the belief that Nature owes our civilization something. Nature is neither benevolent nor malevolent toward us; it is indifferent to our fate.
Supervolcano eruptions are a fact. The study of the geologic record post-dates the emergence of our civilization, so it isn't surprising that the way our civilization operates doesn't take the possibility supervolcanoes into account.
GP's reaction is fairly typical of the "reasoning" of the benevolent nature school: a supervolcano eruption in the near future would be a threat to civilization, therefore we can discount that possibility. That reasoning applies across the board to anything like climate change or sea level rise. We're not prepared for it, therefore it can't happen..
It took 4.5 billion years for an intelligent species to emerge on the planet. In our species 300,000 year history, civilization is a novelty, barely 5,000 years old, the most recent 1.6% of our species' lifespan. Yet because 1000 years is a long time to us as individuals, we see civilization as something enduring and stable. There's no evidence to support that notion on a geologic timescale.
Re: a pattern lately (Score:4, Informative)
The geologic timescale is exactly why the odds are against an eruption in the next few decades. And with an eruption that massive, there are likely to be years of very clear and indisputable warning signs all over the region. I highly doubt a supervolcano eruption will catch civilization by surprise.
As a recent (by geologic scales) example, no one was surprised by Mt St Helens actually erupting. Everyone knew it was coming. Only the precise timing was unknown. And the way it erupted was surprising, of course. But at this point, scientists are pretty good at predicting impending eruptions. I just don't think predicting one decades out is anything more than speculation, considering that this is a pretty radical departure from conventional wisdom.
For extra-ordinary claims like this, you'll need fairly extraordinary evidence. And not to impune Ms. Shamloo, but this is a grad student we're talking about, not a professional volcanologist with decades of actual experience. As such, it's wise to consider the source of this theory in regards to its feasibility.

I remember Mt St. Helens very well, because I was working as a technician in the lab which sent seismometers there. It's an irrelevant example, because the Mt. St. Helens event is something that could be prepared for with a few weeks warning.
The larger scale the event, the longer you need to plan for it. A supervolcano can eject several thousand cubic kilometers of material. Mt St. Helens ejected 0.21 km^3. The last Yellowstone super-eruption was roughly twelve thousand time larger. If it happened today it would bury everything from California to Chicago in 10 feet of ash. It would effectively halt agriculture worldwide for several years. Given that the world's global food reserve is only adequate (if perfectly distributed) for 73 days, how many decades of planning do you think we'd need to be ready? How much of that time would be spent debating whether this was real, then debating on who was going to pay?
