From what I can tell, they look like this....

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.
Hmmm, if Yellowstone blows on Feb 11, I’d say the (Iranian) Muslims win.
More than 1,200 tiny quakes hit Yellowstone Park

What you wrote is just beautiful!
We have stayed at Yellowstone and understand the beauty.
Thanks.
I sure would hate to lose a red state like Utah.
So, what is the Worst Case Scenario??? How much of the US would be affected?
Agree, closer to the surface on average than before.
First stage then would be yellow, right? A yellow alert being activity slightly above background? Yellowstone is normal green right now. I assume it is your interpretation of the data, and not the USGS’s, that indicates a potential yellow alert?
Are you referring to the water displacement? Those records are also on the web somewhere. I’ve lost all my links of last year’s swarm information.
In other words the current madison river seismograph?

Google Earth shows them in almost real time.
“I had no clue what the title was referring to, not being familiar with USGS terminology.”
An earthquake swarm is a series of quakes occurring in the same approximate place in the Earth’s crust.
My guess is that Yellowstone would most likely erupt by gas and or hydraulic/steam pressure. This would not be the caldera shaping catastrophic event that is of fame, however, notable and still scenery changing.
The biggest killer of a caldera eruption will be people breathing in Glass shards (the ash). I only see one guy with a mask in that pic.
They seem to be getting more shallow as time passes. They seemed to average a depth of about 8-10 km until today and within the last two hours one was recorded at a depth of only 0.5 km.
Interesting, no?
You’re welcome. Had it in my mind to put up a general store up there in the Wind Rivers, as you’re coming over the pass into the basin going west, and away from the Hole in the Wall gang’s hideouts. Life didn’t flow that direction, I reckon. Some of the tenderest moments of my life there.
One time, out on the Interstate in the middle of the night, in a Toyota Land Cruiser, there were two bucks on a butte, fighting over a doe that was standing off to the side. A full moon was rising behind them, and it lit them all with stagelights Ziegfeld would have been proud of. The doe even sheepishly looked down and away. Stopped the jeep. Right out there on the Interstate. Just to watch. Early summer. Big old moon. High drama.
Then there was the time, later on, driving out past old Bill Cody’s Wyoming retreat, which was in the middle of a high-walled canyon like is out Wyoming way. Here came this thunderstorm and lightning worthy of “The Ten Commandments” at the Red Sea. Rain! Rain! More! Rain! And then lightning and thunder barrel rolling down those canyons like Paul Bunyan’d like to chase old Babe back to Minnesota but quick. Even the wind sheered to wave the tall grass away from Paul & Babe as they was a wrastlin down toward eastern pastures.
"Swarmy" is a word applicable to democrats voting for Obamacare.

If Yellowstone blows...I guess my Freeper days are over...I live 30 miles north of the Park...grateful to be able to visit it many times a year...we take our guests there when they come and visit us..
