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.
Nine paragraphs into the story you’re told there’s no cause for alarm.
Agreed, global warming is the reason for anything bad in our lives.
The poor and minorities hardest hit; they’ll be dying in the streets. Trump’s fault.
On the averages of eruptions, Yellowstone is overdue. So next week is as good a bet as a thousand years in the future.
Must be a slow news day in the old U.K. Yellowstone’s always locked and loaded. Several years ago I read Harry Turtledove’s “Supervolcano”. Harry writes alternate history like Hitler wins WWII and what happens afterwards in the US, UK and Germany and that kind of stuff. His novel about Yellowstone blowing the big one sets the scenes of what happens next and it is pretty frightening. And entertaining at the same time. Harry has a great mastery of humor.
Scientists want to be first to drill into the Earth’s mantle:

A Decades-Long Quest to Drill Into Earth’s Mantle May Soon Hit Pay Dirt:

Like the street preacher that proclaims, “The world will end tomorrow!”, Eventually they’ll be right!................
Long time no hear...................
“I’m wondering who the first seismologist will be who asks for a grant to study drilling large wells and venting to relieve pressure.”
Unfortunately if drilled in Yellowstone, that Genie may not be put back in the bottle. What happens when a balloon is punctured?
Why would anyone want to live above an earthquake fault, let alone puncture a pressurized magna chamber?
The US government already has such a study.
Please let it wait until after March Madness.
Please let it happen before March Madness.
I hope Texas survives. We’ll need adult supervision to run the rest of what’s left of the USA. Lord knows none of the Western Coastal states can do it.
Certainly not a recent photo...we have several feet of solidified di-hydrogen monoxide on the ground currently.
"these findings are no cause for alarm"
So, it's an alert, not an alarm.
That would make the status "Code Ivory" as opposed to "Code Eggshell"
The large spew of ash into the atmosphere would block out sunlight and directly affect life beneath it creating a “nuclear winter”.
Women, children, and minorities hardest hit, of course.
I don’t know if it’s statistically abnormal, but there seems to have been a lot of volcanic and seismic activity worldwide lately. I’ve also been noticing public service announcements on TV warning about natural disasters. Do they know something is up?
