About 640,000 thousand years ago was the last time Yellowstone erupted..
It is believed that 2.1 million years ago, Yellowstone 'Supervolcano' did erupt, it then erupted a second time and the last time it erupted was 640,000 years ago. In 2008, scientists measured high seismic activity showing that Yellowstone could potentially erupt again but hopefully not any time soon. But in proper answer to your question, Yellowstone spewed lava last 70,000 years ago and its most recent super-eruption was 640,000 years ago. Scientists say it is overdue for another eruption but this is all we know so far.
Yes, the crater at Yellowstone Park is a volcanic crater. It is a massive structure that has weathered in the tens of thousands of years since it was last active. That makes is a bit less than easy to identify it for what it is.The caldera is so large that it is classified as a supervolcano (the Yellowstone Supervolcano). It's about 35 by 45 miles is size, and you just know that when this thing went off, it buried hundreds of square miles of land under several feet of ash. It's been about 70,000 years since its last eruption, but it could reawaken at any time. We'll have some warning, but not a lot. And there is no way to stop it from doing what it does. A link can be found below for more information.
One of only a dozen "super volcanos" in the world. When super volcanos explode it changes life on earth. The last time one went off was Mt. Toba 70,000 years ago.In more technical terms, the Yellowstone volcano is a caldera. Most Caldera volcanoes start out as stratovolcanoes, but this one appears to be an exception.
No. The last time Yellowstone erupted there were no people around to be affected.
Most likely not. Seismic stratigraphy suggests that the magma chamber has solidified too much for an eruption to occur. That could change if there is a fresh injection of magma from the mantle.
Yes. It erupted 3 time in the last 2.1 million years
There is no reason to believe Yellowstone will erupt any time in the next century.

No. No supervolcanoes are expected to erupt any time in our lifetimes. However, ordinary volcanoes erupt every year.

Yes, the when is likely not soon enough for it to be an issue for you (soon is 500 years in geographic time)

1707
Last time was 600,000 years ago
last time it erupted was in 1786
I know of some time in 2005.
