"The most detailed seismic images yet published of the plumbing that feeds the Yellowstone supervolcano shows a plume of hot and molten rock rising at an angle from the northwest at a depth of at least 410 miles, contradicting claims that there is no deep plume, only shallow hot rock moving like slowly boiling soup."

Just for FordGT90Concept because i know he knows about super volcanoes.

Panics! *sticks head in the ground like an ostrich* The Earth is going to get 4C colder in the years following that eruption. The world's food supply will be greatly diminished during that period as well.

It is not a question of "if" it is going to erupt, it is a question of "when."


As North America slid southwest over the hotspot, the plume generated more than 140 huge eruptions that produced a chain of giant craters -- calderas -- extending from the Oregon-Idaho-Nevada border northeast to the current site of Yellowstone National Park, where huge caldera eruptions happened 2.05 million, 1.3 million and 642,000 years ago.

These eruptions were 2,500, 280 and 1,000 times bigger, respectively, than the 1980 eruption of Mount St. Helens. The eruptions covered as much as half the continental United States with inches to feet of volcanic ash. The Yellowstone caldera, 40 miles by 25 miles, is the remnant of that last giant eruption.
That's what should be scaring people shitless. These things are HUGE events.
