YELLOWSTONE is “under strain” according to a group of seismologists who are monitoring the potentially catastrophic volcano, prompting fears an eruption is imminent. _____________________________________________________________________________________________________________________________________________________
Yellowstone ERUPTION: Supervolcano under 'STRAIN’ - experts find magma chamber pressure ______________________________________________________________________________________________________________________________________________________
A process known as deformation, where subsurface rocks subtly change shapes, is occurring beneath the surface of Yellowstone which alerts experts.
Researchers state deformation occurs when there is a change in the amount of pressure in the magma chamber and experts are keeping an eye on the development.
Seismologists from UNAVCO, a nonprofit university-governed consortium, are using “Global Positioning System, borehole tiltmeters, and borehole strainmeters” to measure minute changes in deformation at Yellowstone.
In an article for the Billings Gazette, David Mencin and Glen Mattioli, geodesists with UNAVCO, say “the strain signal is larger than would be expected if the crust under Yellowstone were completely solid”.
This would suggest lava is flowing, allowing pressure to build in the chamber.
The duo said: “These independent observations agree with other instruments at Yellowstone, like seismometers, that indicate a zone of semi-molten rock starting about three miles beneath the surface.
“We say semi-molten because the entire zone contains only between five and 15 percent liquid rock that occupies small pockets of space between solid rock.”
However, they add “these findings are no cause for alarm”, and these measurements are consistent for a volcano which has been building up for close to a million years.
The Yellowstone Caldera supervolcano last erupted 700,000 years ago but experts say it should blow every one million years or so.
If the Wyoming volcano were to erupt an estimated 87,000 people would be killed immediately and two-thirds of the USA would immediately be made uninhabitable.
The large spew of ash into the atmosphere would block out sunlight and directly affect life beneath it creating a “nuclear winter”.
The massive eruption could be a staggering 6,000 times as powerful as the one from Washington’s Mount St Helens in 1980 which killed 57 people and deposited ash in 11 different states and five Canadian provinces.
If the volcano explodes, a climate shift would ensue as the volcano would spew massive amounts of sulphur dioxide into the atmosphere, which can form a sulphur aerosol that reflects and absorbs sunlight.
The kind who monitors the wells from Florida maybe. But hearing some of the stupid ideas being spouted on global warming just mark my words, someone will suggest a study on the feasibility of it.
I know. I do miss the free time though, and the people here. Since Laz is on facebook uncensored I at least get my chuckles for the day usually.
If Yellowstone goes big there won't be anywhere for an awful lot of people to run to. I'm sure there will be plenty of Gaia worshipers that will find great joy and comfort in the reduction of human life while crying over the loss of plants and animals, i.e. nature
Then the door was open and the wind appeared
The candles blew then disappeared
The curtains flew then he appeared, saying don't be afraid
Come on baby, and she had no fear
And she ran to him, then they started to fly
They looked backward and said goodby, she had become like they are
She had taken his hand, she had become like they are
Come on baby, don't fear the reaper
Thanks Red Badger. I was trying to hum the Yogi Bear theme, and somehow managed to segue into Wally Gator. 1960s TV show themes beat the ass off most themes done since.

I saw them in concert when that was new!....................
How's it feel to be an Old Fart? I know I'm odd, but I miss when you could actually understand what was being sung. Now I'm damn near deaf and it all sounds the same........except for Rap, it's still C-RAP!
Trump’s fault.
I am now nearly completely deaf.
Total on my left ear and 30 dB down in my right.......and tinnitus in BOTH ears!..............
...and I have the Album on vinyl...............
Yep. I figured it was time for another Henny Penny episode.
Nothing like a little natural disaster to get the Left to say, “It’s Trump’s fault!”
“The Yellowstone Caldera supervolcano last erupted 700,000 years ago but experts say it should blow every one million years or so.”
I see what you did there...................8^)
(assuming anyone cares to arrange one, or attend, for that matter ;-)
OK, so now we know why we have troops in Korea, Germany, Africa, et al.
“This story comes out about every six months.”
Wait - so you don’t believe them when they say that this area with known volcanic activity is less stable than, say the Canadian Shield? (I’m guessing they are getting a jump on getting their grant renewed in the fall.)
“Hey Jim - look at this. The temperature of the geyser pool is over 100 degrees warmer than Lake Superior!”
I probably shouldn’t give them any ideas for a new paper. “Positive correlations in surface water temperatures related to increased tourist activity increasing risk of global warming and catastrophic eruption” Hmm - ever notice how when the number of tourists at Yellowstone goes up - the air temperature goes up too!?
That album was the first and only thing I ever won. At a church youth event!!?? I gave it to a friend - we didn’t have a record player.
I used to be a big BOC fan, even before that album and their TOP 40 song debuts. I had their albums on 8 track and cassette, all of which are gone now.
This time, they left out the “chunks of rock the size of Buicks landing in Minnesota”. I wonder why?
Have you visited our new Cracker Barrel, yet?
Maybe they are FORD people?.............
