“I see. Given my proximity to it, and the even closer proximity of one of my kids... I’d really rather it didn’t blow. But then I guess if it goes big, we’re all screwed”.

I have family in Evanston, WY, south of Yellowstone.

I remember seeing the map of affected areas and most of us on the west coast should be ok...other than the catastrophic disaster nearby. The fallout curves down to a little bit of southern California but as I recall that was it.

However, none of us would ever be the same.

This is obviously due to Gorebull warming. Oh, and it is Bush's fault.

No air quotes?

[laplata]

Yes, it would be bad. I’ve seen those maps and it’s scary.

Earth crust is between 20 and 30 miles typically. I would say this is a narrow area of the crust or could easily say it’s part of the plume that is connected to the mantel.

If that's all there is my friends, then let's keep dancing
Let's break out the booze and have a ball
If that's all there is..."

I read about this several months ago, but a different article, Same story though.

Scary stuff. If and when it blows, and it seems to be overdue, it can cover at least half the US in a layer of ash several feet thick and create an ash cloud capable of blocking sunlight for months, if not years.

Mt St Helens was a small burp compared to this thing. I’m probably not safe here in Texas...

yeah we already know it will blow and cut America in half and kill 2/3rd of the population and damage the climate...and cause global freezing and cause revolutions galore... SO WHAT

[zzwhale]

its 1/4th the size of the Grand Canyon.... good put it to use..

FILL UP 1/4TH OF THE GRAND CANYON WITH IT....

ok whcih is going to happen first...
the giant tidal wave coming from the azores with a 200 foot sunami like effect or yellowstone blow its top...

There is a brittle solid portion of the mantle that, together with the crust, makes up the lithosphere. These mantle plumes are semi liquid and originate a lot deeper into the mantle and rise into the lithosphere and eventually into the crust. What you are seeing in this article is a plume in the lithosphere. If you look at the depth of many earthquakes you will see that the deep ones are in the brittle portion of the upper mantle. So it’s more complicated than crust-mantle-core.

Maybe both at once and we get a giant sauna.

Thank you for that information

[Smokin' Joe]

Part of the plume, I would think. Isostacy would have the crust generally thicker in the vicinity of Yellowstone—just to ‘float’ the mountains in the area on the mantle.

Thank you
