Scientists closely monitoring Yellowstone. 200 degree ground temperatures reported.

Look closely just to the left and center of the plume - is that a trout?

Be careful what pictures you post on FR in full... (that is why included both links in my post in 146.) That is why you should just post a link to them.

The largest shock to occur during this report period was a magnitude 2.2

That's about the shock of 2 fully-loaded watertrucks hitting each other headon at 35 mph if you were standing 200 yards away.

Oh? You're a troglodyte?

"The plume from Pinatubo was 26 miles high."

I remember it vividly - it passed over Saudi Arabia just about the same time the smoke from the Kuwait oil fires did.

It was an incredible "other-wordly" cast over that part of the world.

Actually reminded me of the end of the world.

So let's use some nuclear demolition and vent the pressure gradually. "Lance the boil" as it were.

Damn! And we just got a new library too.

"More on Thera. "

Yup. Thera/Santorini/Akatori...was a biggie. The plume would have had to be 30 miles high to be seen in the Nile Valley of Egypt. ("Staff by day, Torch by night")

BTW, in the 1300's Thera was owned by a Jewish guy named Joseph Nazi.

This is the park of OLD FAITHFUL. You can practically set your eon by it. I just hope Hillary rushes in to be the first for a photo-op. Oh, the sackcloth and ashes!

Then Ol' Crusty the Pantsuit would get even crustier!

The inverse square law applies to forces dissapating over a spherical surface like gravity, light, etc.

The blast is likely to dissapate radially outward along a cylindrical surface due to gravity pulling downward on the upper surface. Hence the inverse square law may not apply.

[MarkeyD]

No, they're not. Wonder why.

They're afraid we might all move to France.

[RightWhale]

Probably because of the danger that the ash presented to later scavengers

Could the ash set up like concrete quickly? Seems like Pompeii was not loose dust, but fairly hard material. Shovels wouldn't do a lot of good.

[bootless]

Some expert info, please? And happy new year, C_O. You're one of my Freeper heroes. :-)

[Zack Nguyen]

LOL.

[RightWhale]

we might all move to France

Oh, the horror! LOL

I got a kick out of this information:

Snake River Plain - Yellowstone Volcanic Province

--------------------------------------------------------------------------------

From: Wood and Kienle, 1990, Volcanoes of North America: United States and Canada: Cambridge University Press, 354p., p.149-150, Contribution by Charles A. Wood.

An 80-kilometer-wide swath of basaltic and rhyolitic volcanism cuts across southeast Idaho for 450 kilometers. This Snake River Plain-Yellowstone (SRPY) volcanic province is the most dynamic area of volcanism in North America. This is not because of abundant historic eruptions -- there have been none -- but rather because of its rapid motion. SRPY is propagating to the northeast at 3.5 centimeters per year (Armstrong, et.al., 1975); it will slice through Montana and be at the Canadian border in approximately 20 million years. If past activity is a guide, SRPY doesn't simply cover terrain with volcanic rocks, but rather the pre-existing ground subsides up to 6 kilometers (Braile, et.al., 1982) between major faults (Sparlin, et.al., 1982) and is further churned up by the transit of magma and the formation of magma chambers. SRPY is a geologic roto-tiller.

According to the radiometric dating of Armstrong, et.al. (1975), SRPY activity began approximately 15 million years ago with silicic volcanism in southern Idaho. A series of now buried rhyolitic calderas formed in a northeast progression, with abundant basaltic volcanism lagging behind by 2-5 million years. Island Park and the two Yellowstone calderas Island Park is now being colonized by the basaltic wave of magma. ...

Oh, OK. 20 Million years from now. Let's see - will humans still even be around by then? ;-)

One thousand cubic kilometres of lava would pour out of the volcano, enough to coat the whole of the USA with a layer 5 inches thick.

That's 5.02 inches for just the continental U.S. or 4.2 inches for the entire U.S. including Alaska and Hawaii and possessions.

The plume from Pinatubo was 26 miles high

The PBS show Nova did an episode on that eruption-they had a crew with the USGS guys who showed up when it started rumbling and advised the military on when to evacuate.

The video they got of the eruption was awesome
