Much more to the point, the Yellowstone super-volcano is going to errupt all by itself "soon". (That's a geologists' "soon". Something like within 300ky, probability 0.9).
So it probably won't happen within our lifetimes. OTOH, when it does happen, one might expect it to usher in global starvation, anarchy and war, leading to the death of at least half the human population of the planet. (It could be much worse than that). Statistically, that's around a one in 10,000 chance it'll kill you. And there are a dozen or so other supervolcanoes around the planet!
Unlike looking out for large meteors, I'm not aware of any even slightly plausible way to tame a magma-filled supervolcano reservoir.
