No super-volcano has gone off in recorded history.

Known super-volcano explosions:
Estimates of the volume of ejected material are given in parentheses.

VEI 8 eruptions have happened in the following locations.

Lake Taupo, North Island, New Zealand - Oruanui eruption ~26,500 years ago (~1,170 km3)
Lake Toba, Sumatra, Indonesia - ~75,000 years ago (~2,800 km3)
Whakamaru, North Island, New Zealand - Whakamaru Ignimbrite/Mount Curl Tephra ~254,000 years ago (1,200-2,000 km3)[5]
Yellowstone Caldera, Wyoming, United States - 640,000 years ago (1,000 km3)
Island Park Caldera, Idaho/Wyoming, United States - 2.1 million years ago(2,500 km3)
Kilgore Tuff, Idaho, United States - 4.5 million years ago (1,800 km3)
Black Tail Creek, Idaho, United States - 6.6 millions years ago (1,500 km3)
La Garita Caldera, Colorado, United States - Source of the truly enormous eruption of the Fish Canyon Tuff ~27.8 million years ago (~5,000 km3)
The Lake Toba eruption plunged the Earth into a volcanic winter, eradicating an estimated 60%[6][7][8][9][10] of the human population (although humans managed to survive, even in the vicinity of the volcano[11]), and was responsible for the formation of sulfuric acid in the atmosphere.

Hence, "recorded history".

It would be interesting to know if they are reducing the amount of visitors permitted in the park or stopping people from visiting altogether.

Yellowstone has blown it's top three times in the last 2.1 million years.

The three supereruptions occurred 2.1 million, 1.3 million and 640,000 years ago; forming the Island Park Caldera, the Henry's Fork Caldera, and Yellowstone calderas, respectively

From 2.1 million years ago to 1.3 million years ago there are 800,000 years.
From 1.3 million years ago to 640,000 years ago there are 660,000 years.

Since we've only got three data points it's tough to make any judgments but the data seems to suggests that an eruption could occur at any time.

I wonder what all of those people who actually believe that the Earth is 6,000 years old think about all of this....

There's interesting spacing between the activity.

If it is haarp or haarp accidents, will it be less in the middle of the night?


My neighbor was flown to mt. st. helens - before he retired he was quite the seismologist I gather. I sent him the link and he said a Bob Smith with Uni of Utah would be the one to ask about this. I'm going to try to look him up. He also said that before st. H blew the activity was around 1000 a day in one spot like this and we're not there yet.

He's a calm elderly gentleman, I'll let you know what else he says after he looks at the links and gets back to me you know - these things can't be rushed

Those people don't think.
Sorry, couldn't resist

The Yellowstone “supervolcano” rose at a record rate since mid-2004, likely because a Los Angeles-sized, pancake-shaped blob of molten rock was injected 6 miles beneath the slumbering giant, University of Utah scientists report in the journal Science.

“There is no evidence of an imminent volcanic eruption or hydrothermal explosion. That’s the bottom line,” says seismologist Robert B. Smith, lead author of the study and professor of geophysics at the University of Utah. “A lot of calderas [giant volcanic craters] worldwide go up and down over decades without erupting.”

The upward movement of the Yellowstone caldera floor – almost 3 inches (7 centimeters) per year for the past three years – is more than three times greater than ever observed since such measurements began in 1923, says the study in the Nov. 9 issue of Science by Smith, geophysics postdoctoral associate Wu-Lung Chang and colleagues.

“Our best evidence is that the crustal magma chamber is filling with molten rock,” Smith says. “But we have no idea how long this process goes on before there either is an eruption or the inflow of molten rock stops and the caldera deflates again,” he adds.

The magma chamber beneath Yellowstone National Park is a not a chamber of molten rock, but a sponge-like body with molten rock between areas of hot, solid rock.

And

Conventional surveying of Yellowstone began in 1923. Measurements showed the caldera floor rose 40 inches during 1923-1984, and then fell 8 inches during 1985-1995.

GPS data showed the Yellowstone caldera floor sank 4.4 inches during 1987-1995. From 1995 to 2000, the caldera rose again, but the uplift was greatest – 3 inches – at Norris Geyser Basin, just outside the caldera’s northwest rim.

During 2000-2003, the northwest area rose another 1.4 inches, but the caldera floor itself sank about 1.1 inches. The trend continued during the first half of 2004. Then, in July 2004, the caldera floor began its rapid rate of uplift, followed three months later by sinking of the Norris area that continued until mid-2006.

Smith believes that uplift of the middle of the caldera decreased pressure within rocks along the edges of the giant crater, “so it allowed fluids to flow into the area of increased porosity.” That, in turn, triggered small earthquakes along the edge of the “pancake” of magma. The amount of hot water flowing out of the deflated Norris area is much smaller than the volume of magma injected beneath the caldera, Smith says.

This is from an article written just over a year ago. I recommend reading the whole article, it's very informative.

on the website these type of quakes are said to be normal...why is everybody panicking, if the "quake scientists" are not?

Well so far folks, here in Casper its quiet, cept for a bit of wind, no ground shaking, nothing falling off the walls, pretty much a quiet evening in central Wy.

If Yellowstone pops its top, or begins to, that will be felt for miles in every direction. When it does go, from where I am at, I will have about 30 minutes to get out of dodge and at least be just ahead of the outer edge of the nice sulfer filled soot.

According to the predictions, that cloud will envelop an area of 300 mile radious in 30 minutes, possibly even less.


Neat..eh?!!!


Cheers!!!!

EVERYONE in North America would/will die if this thing erupts... as well as 60-70% of the remaining world population.

We need to look at ground temps. Those not available?

Maybe not just ground temps but also lake temps
As those quakes have only been hitting the lake...

Now, I am still not 100% sure how to interpret this data from the LKWY correctly, not even after reading instructions, but if you put the day-to-day data behind each other, starting just after Christmas on 12-26 there seems to be an intensifying pattern:

Does not look like de-escalation to me. Nice green spike just now. I think I´ll have a look at the data from the other nearby recorders as well.

Yes, it was pretty much calm before the swarm. I've read anyway that strong winds can bring much noise in seismograph charts. If in the last days the weather in the area has worsened maybe the "busy" lines in the charts are because of it, and not volcanic activity.

We dont call it "Windy Wyoming" for nothing!

Gets very windy out here. I think the worst place for wind however is not up near Yellowstone, but in Rawlins and all along I-80. Worst areas for wind. If you dont want a bad hair day, avoid southern Wyoming!



Cheers!!!!

These are the three measuring stations closest to the lake LKW, YLT & YTP:



I apologize for the large post, but the images are duly compressed and I think it is good to see the overview on a single page.

Wasn´t someone´s dad in here a famous seismologist? Could that someone maybe ask his dad to interpret this chain and give a professional opinion? Thanks in advance
