Since January 17, 2010 Yellowstone has had the second largest swarm ever recorded. The swarms have been steady at about 10 miles in depth and they have subsided a few days ago.
In the past two days the depth has raised up to around 7 miles and in the past couple hours quakes vastly increased.

Remember this doesn’t mean we will see an eruption and it most likely means a normal volcano. It is very unlikely we will see a caldera eruption.
But these changes are significant and cannot be over looked
Some history:
Since the most recent giant caldera-forming eruption, 640,000 years ago, approximately 80 relatively nonexplosive eruptions have occurred. Of these eruptions, at least 27 were rhyolite lava flows in the caldera, 13 were rhyolite lava flows outside the caldera and 40 were basalt vents outside the caldera. Some of the eruptions were approximately the size of the devastating 1991 Pinatubo eruption in the Philippines, and several were much larger. The most recent volcanic eruption at Yellowstone, a lava flow on the Pitchstone Plateau, occurred 70,000 years ago.
Thanks to all for the replies on this very interesting subject. The Toba catastrophe theory sure sounds biblical.
Because they like cheese.
Thanks. I’ll take a closer look at it tomorrow. Gotta get to sleep. Does look interesting. Do you have a link to the article?
But with my wood stove, a forest of trees around me, my own well water, I'd be better off than most - it's food, after a month or so, that would be a problem.
If this goes up even as a small caldera eruption then the US/Canada looses the bread basket of the Midwest. Our cities would run out of food in a matter of weeks. While the rest of the world may cheer in the beginning, without the food aid we provide large parts of Africa and Asia would starve.
Food riots would breakout in most US cities east of the Rockies. Clean water would also be hard to come by. Rivers would be choked with ash; the increased weight would rip bridges off their pilings making overland travel nearly impossible. Supplies to major cities would have to come by sea if anyone sends us some.
Air travel would be difficult in many areas of the US and impossible for several weeks in the Midwest. Depending on how long the eruption lasts.
The ash cloud would cover the globe; crop yields around the world would drop, especially in non industrialized nations.
The eruption would kill hundreds of thousands of people in matter of hours or days. The resulting social upheaval of having the US removed so quickly as the producing and military superpower in the world would kill billions.
It may not be Armageddon, but it’s a darn good preview.
Interesting for sure.
lol, out would pop Nancy.
What things would be like in much of the US if the caldera blew
You mean the trucks would have only one light working? Gadzooks!
My wife takes pills for them harmonic tremors. Hide them pills and the fat lady sings!

Actually, SUPERVOLCANO (2005), made for TV. A British production, I believe. Rated “Not That Bad”, on a scale of 1 to 10.

I spent a year in Big Timber in ‘58-’59. It was 40 below at Red Lodge south of us one night. The oil in my little Studebaker coupe was thick as molasses. Back then the grizzly and brown and black bears were everywhere. We were college students and like the idiots we were, we fed them through the open windows of our car.
The characters depicted in this film
are fictional.
The events are based on fact.
... say no mo’ ! say no mo’ !
Calming down for the night?
All and all I think Steve’s call that they might upgrade to a watch level is appropriate.
Now there’s a blow job I’d pay for!
