Scientists don’t know what caused the geyser to erupt 3 times in the last 2 months. They say the recent eruptions are not a sign of an impending caldera eruption
Seismologists have discovered a reservoir of hot, partly molten rock hidden some 12-28 miles beneath Yellowstone National Park’s super-volcano. The magma could fill the 1000 cubic-mile-Grand Canyon more than 11 times.
It last went off some 63 million years ago and is no closer to going off than before last week, but now we know we’re sitting on a keg of dynamite and not just a stick...
Lurking beneath Yellowstone National Park is a super volcano. One that hasn’t erupted in 600,000 years. New research shows that the caldera below Yellowstone (which is one of the biggest in the world) is a lot bigger then we previously thought.
