ACF, I don't think Yellowstone's bang will be that big a deal. 1000 km3 is only about what Taupo pops out regularly. That's only 10km x 10km x 10km. It's not enough to cause TeoTwawki though it would not be good for anyone within 300 kilometres of the bang. I'd better get out a map and see what will be destroyed in 300km radius of Yellowstone.

Neither do I buy the volcanic winter argument. When Taupo blew up, there were nice sunsets around the world, but Europe didn't come to a halt. I don't believe human populations were affected by Yellowstone's last eruption.

Taupo is a banger, which releases suddenly when pressure on top reduces sufficiently for the column of superheated liquids to turn to gas. As soon as that process starts, with the most volatile gases first, the whole column goes up in one huge expanding-to-gas roar, with hydrocarbons converted to fire, smoke and noise. It would be very exciting to watch the process. But I'll do it via tv.

The confluence of events to watch out for is:

1.....Moon and sun aligned for maximum high tide in the crust. Just as the Moon and Sun pull the oceans and make tides, they pull Earth's crust.

2.....Low ground water level, which reduces pressure, like taking the knob off a pressure cooker.

3.....An atmospheric low pressure.

4.....An earthquake to shake things up.

5.....The right time for pressure to have built up in the magma chamber.

4 and 5 are ready to go any time. So, visit Yellowstone when the ground is saturated with rain or loaded with metres of snow, choose a time when sun and moon are out of phase, and make it a nice sunny day with high air pressure. Walk on tippy toes to avoid shaking the ground.

Don't live at, or own property in, Taupo or near Yellowstone.

PS: I see from that map you linked to, that Yellowstone is way out by Wyoming and Montana, with low populations and no big deal if it blows up anyway. Well, a big deal, but not TeoTwawki. Osama wouldn't rate a mention that day.

Just thinking about it, the answer is for the USA to turn the Yellowstone caldera into a giant rubbish tip. Build a mountain of rubbish on it, 10 km high, which would be like increasing the pressure in a pressure cooker. Eventually, something will give, but the problem could be sat on for 1000s of years more. It would be a tourist attraction. The world's biggest trash heap. People could ski on it!
