Yellowstone Lake Hints at Buildup to Hugh Blast.

Agreed, lets face it we test nuclear weapons underground and we see a ripple on the surface, these explosions happen underground and blow 20+ square miles of the earth above them into the atmosphere.

Which is why I said we really can't fathom the force on the human scale.

I feel fear and deep concern from the front-line scientists
in yellowstone, just by the wording and providing us all
key clues, and slow release information...via media.

I know they must be careful, because of panic...

The evidence is being reported, and I say to all those in
emergency gov't on all levels, prepare yourselfs and your families, and be perpared to survive without any gov't help
for days,weeks, or months ??? If Yellowstone Blows...???

I pray it don't, but at the same time prepare yourselfs....

The Boy Scouts motto......"BE PREPARE" !!!

Maybe I'll get to use all my Y2K supplies after all.

I read the article in the Denver Compost yesterday but in their usual "everything is fine, go back to sleep" style they didn't mention what would happen if this thing actually blew. I heard a guy on the radio the other day talking about Yellowstone and other "supervolcanoes". It made my hair stand up. Not much I can do about it though.

Experts: Mountain is more unstable than previously thought

a "pressure cooker" effect

Why don't they install one of those wobbly pressure cooker valve things? It would have to be a tourist attraction in itself, a few hundred tons of weight bouncing around on a pipe and releasing a ton of sulphurous steam every few seconds.

That's pretty funny.

True.

But, nully likes!

Not those kind of pastors. But anyway.

Given the prevailing winds - generally from west to east - the destruction to the west would only be a 100 miles or so. My guess, nothing more.

That may hold true with conventional volcanoes, but Yellowstone is no conventional volcano. When supervolcanues blow their top, the ejecta travels upwards and outwards in a parabolic arc in ALL DIRECTIONS...some scientists believe that supervolcano eruptions may even be powerful enough to blow some material into low orbit. The heat, speed, and density of the ejecta allow it to, at least temporarily, overpower the prevailing winds and rain ash on a roughly circular area around the vent...a 60MPH upper air current simply can't deflect a wall of ash that may be initially moving at several hundred miles an hour.

Of course, if I were within a couple hundred miles of this thing, I'd more worried about the mountain sized boulders raining down on my head than the depth of the ash fall!

I'm trying to imagine what that would look / sound like.

We have all seen the Mt St Helens film, at least I have, many times.

Not even close.

Did you ever see the documentary of Mt Pinatubo in the Philippines? Excellent.

My favorite line - the military brass at Clark AB was in continuous contact with the boys from USGS. When it came to the main event, one of the scientists said, "General, I hope you got some jam in your pocket 'cuz were about to be toast!"

Amazing stuff.

Yellowstone Lake Hints at Buildup to Hugh Blast.

Women and minorities at most threatened..

[Axenolith]

It probably needs to rise to close to 300 degrees to start to boil at 65 feet deep due to the pressure...

[cmsgop]

70,000 years ago..was the last time when Mars came by close to Earth

I think I heard that Mars will be real close again this month or Sept...

If you're close enough to see it go off, you won't live to tell anyone. For someone 100-200 miles away, however, I'd guess that it would look like a massive black cloud racing across the sky...until it started raining mountain sized boulders on you. Interestingly, because the thicker ground level air would slow down the lower half of the blast more than the thinner air would at high altitude, an observer at this distance would probably be able to watch the cloud, magma, and its mountain sized boulders race past high above for several minutes before the ground level blast struck him.

Viewers closer to the blast would simply see a black wall race up and out of the caldera, reaching endlessley into the sky above, and out in every direction...towards them. Like nuclear blasts and tidal waves, it would already be too late for them to seek shelter. These people wouldn't die from magma, ashfall, or crushing debris impacts, but from the tremendous shockwave created by the blasts air displacement. The air pressure at the leading edge of the shockwave in the area immediately surrounding the blast zone could be increased 100 fold and be accompanied by winds of more than 600MPH...nothing can survive that.
