Yellowstone ERUPTION: Supervolcano under 'STRAIN’ - experts find magma chamber pressure

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.

Its the weight of the extra CO2 in the air pressing down on the mantle and squeezing it like a zit

I think they are searching for a gentle way to say that about 200 million Americans are gonna die. (Women and minorities hit hardest.)

And when? Last time I read about this it was something like in the next 10,000 years or more. Not next week.

I’m wondering who the first seismologist will be who asks for a grant to study drilling large wells and venting to relieve pressure.

Hell just the idea alone should be worth a few million a year in funding - You heard it here first people!

Wait for it... wait for it... nah.. forget that.

When something erupts every ‘million’ years or so I’m guessing we’re probably all safe for at least another millennium or two.

“This story comes out about every six months”

Every since the last time it blew 700,000 years ago.

Global Warming or Global Cooling?

Definitely a Climate Changer!

Oh well.

I guess it would be our turn if this happened.

Winter would last a bit longer this year.

“these findings are no cause for alarm” And the rest of the article kills us all off.

Dry wit? ;-)
