Yellowstone super volcano.

Whats the point in settin off the volcano now insted of waiting fo rit to bow up by itself?

another version same story, and a Question
http://www.rense.com/general41/yellowstoneupdate.htm
why would the thing explode if the presure is dropping?

Rense.com is not a science site; it's more like a news agency with a lot of advertising thrown in.

Superheated water under pressure remains liquid, once the pressure drops it will expand and turn to steam instantaniously - BOOM!

It's still not quite right. A boom is the result of pressure, however that pressure happened. If the pressure drops, then some of the hot water does become steam, but only to offset the dropping pressure. No boom.

The way you get a boom from a volcano is to release containment. The gasses are disolved at about a 200 to one ratio. Since the magma chamber is 10 x 30 x 70 kilometers, there are 10,000 cubic kilometers of magma. When the cap break integrity, 2 million cubic kilometers of disolved gases at standard temperature and pressure suddenly jump out of a 2,000 square kilometer hole in the ground at 2,000 degrees Celsius and 3,000 PSI, dragging all kinds of rocky debis and ash with it. Now you've got a boom.

You can't honestly believe that a volcano could reduce the earths population from 6 billion down to single figures?!

Not single figures, but the Toba eruption cut our population down to thee to five thousand individuals worldwide.

In one way we're more at risk now than we were 74,000 years ago for Toba. Back then we had day-to-day survival skills of providing for ourselves. Today we're dependent on technology and infrastructure for survival. If you tun on the faucet and water doesn't come out, what do you do? Once the cans are gone from the grocery shelves, what do you eat? Where do you drive when your car runs out of gas and the stations are empty? How do you cook when there's no electricity and not gas? What do you do when you have an asthma attack and you can't find any inhalers? You die, like billions of other people will.

the evidence isn't conclusive as to whether or not the crust composition is the same as it was prior to previous eruptions.

Huh? It's the same. What's gonna change it?

what are actually the 'ashes' spitted out by volcanoes?

Volcanic ash is powdered glass. The bigger stuff is just big rocks dropping on your head.

Maybe 3 or four hydrogen bombs in the high atmosphere could breakdown the dustcloud before it spreads out?

Maybe waving a handkerchief at a runaway boxcar will stop it dead in its tracks. The supervolcano is tens of thousands of times bigger than three or four hydrogen bombs.

Winston Churchill said : "The worst is never acquired for certain".
Meanwhile, let's stop lamenting and speculating and let our scientists, technologists and even sci-fi authors "brainstorm" many innovating ideas about how to prevent and/or mitigate such catastrophic events. Just saying "no future - we're doomed" is just being cowardly and certainly NOT in the American spirit and character !

Pot Volcano

What is going to happen before it goes is like this. First the walls will super heat causing the center to receed. This is why the mountains are shrinking. As the fluid is super heated it starts to move more rapidly . This will be noted by tremors. The tremors will be shadower as the fluid moves to the edges like water under glass forced against the walls. Once then the cool center is met by its hot counter partner a process of heat exchange accures forcing the cool down and the hot up , until a critical temp is reach within the fluid. When this happens the center will rise up and down rapidly, then the whole chamber will just rise like water in a tasunami throwing out its plug and giving no warning in so doing as it has its own time vs heat table of its own. May God help us all if it goes.

Stop making stuff up please.

Stop making stuff up please.

Dyeman, I'm inclined to agree. Specifically:
1. Why would the walls superheat? What, indeed do you mean by superheat?
2. Where is the centre receding from?
3. What evidence do you have that mountains are shrinking? And which mountains?
4. Which fluid is being superheated and where is it moving to rapidly?
5. Why would the tremors notice anything?
6. 'The tremors will be shadower'.:shrug: Could you do that in English?
7. As the fluid moves to the edge of what? And what are the two solid bodies the fluid, whatever the fluid is, is trapped between?

Anyway, I could go on, but you get the general idea.

I know it is not much of a welcome for your first post, but honestly you are not making a lot of sense. Do you want to try again?
