Before a volcano erupts, there are usually signs of what’s to come; small earthquakes, heat emission, and ground swelling, to name a few, have all been observed to precede eruptions. Volcanologists also monitor the changing composition of gas emissions at volcanoes in the months leading up to an eruption. However, precursory variations in gas have not yet been verified to occur in volcanoes hosting active lava lakes.
To find out if volcanic gas emissions might also be used to predict eruptions at lava lake–hosting, carbon-poor volcanoes, Aiuppa et al. looked at Chile’s Villarrica volcano. Villarrica towers 2847 meters over the town of the same name; magma bubbles and spatters in an open-vent lava lake at its peak.
In this study, the researchers installed a multicomponent gas analyzer system (Multi-GAS) to bring the volcano into the Deep Carbon Observatory’s Deep Earth Carbon Degassing network. The instrument was placed on the outer rim of the lava lake in November 2014 to record the ratios of carbon dioxide and sulfur dioxide gas emitted from the magma. Magma, which contains dissolved gas, rises toward the surface of the magma chamber. As the pressure decreases on its ascent, the gas bubbles burst at the surface, and the degassed magma sinks back down into the chamber.

With the interest in Yellowstone currently, this study may be important even though the volcano studied was not as complex as a super volcano would likely be due to drastic differences in the magma pools.
Seems like common sense...
Can Volcanic Gas Levels Predict an Eruption? Well...it certainly can at my house. Especially on chili night.
Finished a 16 hour pork butt yesterday at noon.
Wasn’t sure last night if the Yellowstone Caldera was shaking or if it was me...
NASA is looking into it
NASA wants to probe Uranus in search of gas

Campi Flegrei. This is the one to watch.
Yellowstone? Nope. Unless there comes a earthquake over 7 in that basin. That might unzip the thing.
I always disliked that picture- she looks like she is letting out a squeaker.
I don’t know about volcanic gas but it works with me.
“Sexy” Megyn is as appealing as a bucket of aholes.

I swear she looks like a tranny in drag, in that picture.
She’s a thoroughly unpleasant person gas eruptions or not.
No I do not. Havent really paid much attention to that one until these past weeks.
As far as Yellowstone is concerned. These events of the last few years are pretty normal for that system. Will it blow? YUP. WHEN? Dont know. How big? Dont know. But even the latest ones did not do the damage like the doomsdayers are claiming.
I would guess a VEI 5 or something like that and not a super eruption. A tad bigger than St Helens. Maybe something like Tambora in 1815-16 which created havoc all over the world.
These dam freaks and their panic producing web sites..they do this to get hits on their web sites.

I have a kamado style ceramic grill and I smoke at 220.
Have this little helper: https://bbqguru.com/StoreNav?CategoryId=1&ProductId=34
It’s really fantastic.
Have a wonderful brisket!
Mmmmm....BubbaQ. Yum.
