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

    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.

    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.

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

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

    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.

    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?
