Did you know there’s a “supervolcano” underneath Yellowstone National Park? It covers some 925 square miles and it just “took a deep ‘breath,’” causing the ground to rise 10 inches in some places. Is it going to erupt?

6 volcanoes that could shut down the world
A worrying look at six volcanoes that could have devastating impacts on the world and civilisation.
Here is a taster from the article by the Week.:-
YELLOWSTONE "SUPERVOLCANO" (U.S.)
Last erupted: 640,000 years ago
Effects of a major eruption: When the Yellowstone Caldera, or "supervolcano," in Yellowstone National erupts again, it will render a huge swath of North America, from Vancouver to Oklahoma City, uninhabitable. It would have incalculable human and economic consequences. The last eruption of similar magnitude — 73,000 years ago in Sumatra — plunged the entire planet into a decade-long volcanic winter and nearly wiped out the human race.
Likelihood: Geologists see signs that it could be preparing for another major blowout soon, although "soon" could mean thousands of years.
