Title: Super Volcano is Bigger

YELLOWSTONE NATIONAL PARK -
The world’s authority on Yellowstone’s Super Volcano says it’s more than twice as big as scientists once thought. Does that mean it’s more likely to blow up soon? Penny Preston found Dr. Robert Smith at his home near Grand Teton, and found the answer.

Millions of people visit Yellowstone each year to see its geysers, fumeroles, hot springs, and mud pots. It’s the largest concentration of thermal features in the world. The park sits on top of the world’s largest active volcano. The Super Volcano. Its most recent eruption was more than 600,000 years ago. All that remains is the top, or caldera.

When you come into the Park they’ll give you a map and it has an overlay of the caldera. It’s huge.

The scientist who knows more about the Super Volcano than anyone, Dr. Robert Smith of the University of Utah, said, “Anytime you come to Yellowstone you have to drive uphill. And the reason is this giant plume of magma, is very hot, therefore it’s bullient, low density and it just lifts the surface up.”

Dr. Smith has been studying Yellowstone’s earthquakes and it’s Super Volcanos for almost sixty years.

He pointed out, “And these giant eruptions, supervolcanos if you wish, probably last many, many months, maybe even years.”

Not only that, they’re huge, thousands of times larger than Mount St. Helens. Smith and his students use siesmographs to map the magma pool underneath Yellowstone’s volcano, and satellites to determine how much the land swells or bulges. They found that the magma is, “2.5 times larger than we had originally imaged.”

The magma movement is signaled by earthquakes. Smith mentioned the 4.8 magnitude Norris area earthquake that damaged Lake Hotel last spring.

He explained, “It’s the biggest earthquake in 30 years.”

So, how likely is it that the big one will blow soon?

“If we were to have another big eruption, it would affect a large area, on the order of several states. But, as I said, that probability is very, very, very, very small. In my calculations it’s point zero, zero, zero, one percent.”

Smith said the magma pool is not getting bigger. His team added a lot more seismographs over the years, and are getting a clearer picture of the magma.

I'm sure if Drip...errr...Trip were still here he'd say this guy was lying.

Said from a man who may have been reincarnated  from some one who argued with someone one from the seafaring area  taking on hundreds of passengers to escape what they knew was impending doom. 

Money and lack of it kept the people of that magical city to stay and become todays tourist attraction, the bodies of those frozen in death under the ash of the pyroclastic explosion that few expected.

One does not mess with Mother Nature, either one adapts or gets the Hell out.
