They say this will happen at some point in 1,000 to 10,000 years but that's only a blink of an eye in geological time.

So - we have time. Just sayin... Yes, we hope. From what they said it's the world's largest super volcano. Nice picture.

They have said that it is one of the largest supervolcanoes, but that statement really needs a caveat. There is a much larger volcano (Shatsky Ridge) on the floor of the Pacific Ocean east of Japan. It is the size of California. The difference is that Yellowstone is active.

I've never heard of that. I guess dying as the result of a volcano is better than being killed by ISIS.

Interesting. You have probably read what I'm going to say but.... I read where a top Russian Army person said all they needed to destroy this country was nuke Yellowstone. Not only is it a super volcano but it's a target.

Not only is it a super volcano but it's a target. A nuke would do nothing to cause an eruption at Yellowstone. The magma chamber is 7 miles below the surface. A nuke, even if detonated at depth, would only excavate a 1,000 feet deep crater - not enough to release the 7 miles of overburden pressure on the caldera.

If it does erupt it would change the planet.
But I believe there is a hot spot under the North American plate, seems like similar to the one that created the Hawaiian island chain. The plate is moving but is the hot spot moving with it?

Our country would come to a screeching halt. It would probably hinder crops and life everywhere on the planet.

The plate is moving but is the hot spot moving with it? The hot spot appears to be stationary. The hotspot has been tracked back in time and geographic location through the Snake River Canyon (where there have been supervolcanic eruptions even larger than Yellowstone) all the way back to Oregon. This track coincides with the movement of the North American plate.

Our country would come to a screeching halt. It would probably hinder crops and life everywhere on the planet. Yellowstone is not the only one that is a threat. In fact, it isn't even the most imminent threat. The one most likely to erupt is the Taupo Volcanic Zone, in new Zealand.
Over 26,000 years ago Taupo exploded in the biggest volcanic eruption the world has known in the last 70,000 years – the Oruanui eruption released 2,700 cubic kilometers of ejecta. Much of the central North Island was buried in up to 200 metres of debris. If you could spread out that volume of debris, it would cover the entire North Island in a layer 10 metres thick! Eighteen centimetres of ash from the Oruanui eruption has been found on the Chatham Islands, over 800 kilometres away. Twenty-four thousand years and 26 smaller eruptions later, in about 233 AD, Taupo exploded in another massive blast. This second eruption was one of the two most violent eruptions in the world in the last 5,000 years. It sent about 30 cubic kilometres of pumice and ash into the air. The eruption column stretched 50 kilometres into the air and, when it collapsed in a pyroclastic flow (a hot, fiery cloud of gas, ash and rocks) it destroyed forests all over the central North Island. There have been many more eruptions, with about one every thousand years or so. The volcanic zone is still highly active today, and is considered to be the most active continental supervolcanic zone. Mount Ruapehu, in the southern end of the zone, is one of the most active volcanoes in the world.

Interesting, maybe they will hold off until we're gone.
