Yellowstone Has a 10 inch Bulge
According to a report in National Geographic, the ground above the Yellowstone supervolcano has bulged upward up to 10 inches since 2004. The report says:
But beginning in 2004, scientists saw the ground above the caldera rise upward at rates as high as 2.8 inches (7 centimeters) a year.This is bad news for those of us who enjoy the finer things in life such as being alive. I predict the hypersonic magma is only seconds away.
The rate slowed between 2007 and 2010 to a centimeter a year or less. Still, since the start of the swelling, ground levels over the volcano have been raised by as much as 10 inches (25 centimeters) in places.
"It's an extraordinary uplift, because it covers such a large area and the rates are so high," said the University of Utah's Bob Smith, a longtime expert in Yellowstone's volcanism.
