Yellowstone Supervolcano Making Strange Rumblings
| Quote From Source: | Though the Yellowstone system is active and expected to eventually blow its top, scientists don't think it will erupt any time soon.
Yet significant activity continues beneath the surface. And the activity has been increasing lately, scientists have discovered. In addition, the nearby Teton Range of mountains, in a total surprise, is getting shorter.
"We think it's a combination of magma being intruded under the caldera and hot water released from the magma being pressurized because it's trapped," said lead study author Robert Smith from the University of Utah. "I don't believe this is evidence for an impending volcanic eruption, but it would be prudent to keep monitoring the volcano."
The data shows that the caldera floor sank 4.4 inches from 1987 until 1995. From 1995 until 2000, the northwest rim of the caldera rose about 3 inches, followed by another 1.4-inch rise until 2003. Then between 2000 and 2003, the caldera floor sank a little more than an inch.
And then from 2004 to 2006 the central caldera floor rose faster than ever, springing up nearly 7 inches during the three-year span.
"The rate is unprecedented, at least in terms of what scientists have been able to observe in Yellowstone," Smith said.

Since they know nothing about when a super volcano is going blow, speculation can be left for anybody. All they can do is record data for the next group of humans to analyize for when they face their El Guapo.
They should take the warning labels off of everything and let stupidity sort itself out.
