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.
What ‘New’ Cracker Barrel?................
LOL, I am the same only reversed, no hope for the right ear. They recommend a BiCross hearing aid setup where the deaf side gets a transmitter and the other side gets a amplifier received but it’s big bucks. At least for me!
Exactly what ever happened to all these screaming buffaloes?
Give me a convincing answer and I just might move back East.
Otherwise, forget it!
CA....
Oh I believe it. Just stating that the same story comes out every six months. The media doesn’t do actual news. These do scare stories.
I loved Henny Penny in the James Bond movies.
BWAHAHAHA!
*choke* That was Miss MONEYpenny! LOL!

“...geodesists with UNAVCO, say “the strain signal is larger than would be expected if the crust under Yellowstone were completely solid”.
No - I get that. And I expect someday it WILL explode as it has in the past. Just like someday (sooner rather than later I think) we will get another 9.0 earthquake in the Pacific Northwest.
But the above quote is just so silly, and obvious.
You sure? “James, make sure the sky doesn’t fall on your head” sounds really familiar...
Maybe you are replying to the wrong person?
You were mentioning about the scare tactics of the press. And I quoted the article about how “the strain signal is larger than would be expected if the crust under Yellowstone were completely solid”.
“larger strain” does sure sound scary. But of course the earth below Yellowstone isn’t completely solid - it hasn’t been for a million+ years. So of course it will have a larger strain that solid earth.
I wonder why this story DOES keep coming up year after year? Is it just to sell newspapers? Are they new reporters that forgot about the story from last year? I imagine the scientists make some calls to get the word out about their NEW findings in order to make the press and bring awareness (and funding) to their pet projects.
“I wonder why this story DOES keep coming up year after year? Is it just to sell newspapers?”
That’s my thought.I just wonder why it keeps getting published. But, that’s the way the media works. You see one article criticizing Trump and then you’ll see at least 15 more saying the same thing. They just repeat each other.
Japan might well be a more likely candidate. Found a six mile diameter lava dome 2000 feet high, residing in the caldera of the previous Kikai super-volcanic eruption site.
