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’ve gone through one volcano, it wasn’t fun.
I bet it was pretty hot in there..................
Bad link. Do you where else it is?
but but but.... corn ....
I made a similar joke about the Pirates making the post season last year in one of these end of the world articles :-). I’m hoping to see the Royals do it this year. The Pirates are still in it this year, but I have a bad feeling about the second half of the season.
I lived in the Yakima Valley. We got most of Mt. Saint Helen’s ash. That was not fun.

How did you get rid of it?
Does it make your gardens grow like crazy?.............
