The magnitude of a Yellowstone eruption, particularly if it were to occur as a supereruption, could be catastrophic, potentially ejecting thousands of cubic kilometers of volcanic material. Such an event could lead to widespread devastation, affecting global climate patterns, causing ashfall over large areas, and disrupting ecosystems. Historical eruptions at Yellowstone have shown that it has the potential for immense explosive power, with the last major eruption occurring approximately 640,000 years ago. While the likelihood of a supereruption is low in the near future, monitoring and research continue to assess the risks associated with this supervolcano.
No. The last time Yellowstone erupted there were no people around to be affected.
An eruption of the Yellowstone caldera occurs it will likely be an extinction level event.
It is impossible to know exactly how much "destruction" occurred in any eruption that has taken place in the Yellowstone Caldera, but the eruption with the largest volume of lava expulsion took place about 1.2 million years ago.
There is no record of the Yellowstone volcano erupting on January 12, 2009. The volcano has not had a major eruption for about 640,000 years, but it does experience minor volcanic activity such as geysers and hot springs.
It didn't. The Yellowstone volcano last erupted about 70,000 years ago. The last super eruption was about 640,000 years ago.
This cannot be predicted. While Yellowstone has produced several eruptions larger than any seen in human history, it has also produced a number of much smaller eruptions.

No. Chances are it would not affect the chances of an eruption.
The largest eruption of Yellowstone, known as the Huckleberry Ridge Tuff eruption, occurred about 2.1 million years ago and expelled approximately 2,500 cubic kilometers of material. In contrast, the 1980 eruption of Mount St. Helens produced about 1 cubic kilometer of material. Therefore, it would take roughly 2,500 Mount St. Helens eruptions to equal the volume of the largest Yellowstone eruption.

In most cases, geologists would see signs of an imminent Yellowstone Supervolcano eruption weeks or even months beforehand. A geologist who specializes in volcanos would be a volcanologist, who are more apt to recognize the incoming signals.
The normal surface movement, magnitude, and intensity at Yellowstone National Park varies from about 1.5 to 3.0. These would be barely noticeable by the average person. But the forest rangers and geologists would notice and be aware of any larger movements.
Yellowstone's last magma eruption was about 70,000 years ago. The last super eruption was approximately 640,000 years ago.
Mega Disasters - 2006 Yellowstone Eruption - 1.6 was released on: USA: 27 June 2006
A small eruption would cause the cities 100 miles within the park to be destroyed, with an hour. If the eruption triggers the supervolcano, it can cover two thirds of the United States.
No. The last time Yellowstone erupted there were no people around to be affected.
