Default Yellowstone supervolcano eruption would cause 90k deaths and nuclear winter

Quote:

The timebomb under Yellowstone: Experts warn of 90,000 immediate deaths and a 'nuclear winter' across the US if supervolcano erupts

It could release 1 ft layer of molten ash 1,000 miles from the National Park

It would be 1,000 times as powerful as the 1980 Mount St Helens eruption

A haze would drap over the United States, causing temperatures to drop

Experts say there is a 1 in 700,000 annual chance of a eruption at the site

A supervolcano in the heart of America's northwest has the potential to blanket the US in a 'nuclear winter'.

If it were to erupt, the Yellowstone supervolcano would be one thousand times as powerful as the 1980 Mount St Helens eruption, experts claim.

While it has lain dormant for more than 70,000 years, scientists say that we can't rule out the possibility eruption this may some day take place - although they say the chances are extremely slim.

The volcano at Yellowstone National Park in Wyoming and Montana sits atop a huge reserve of molten rock and last erupted 640,000 years ago.

It is one of the largest active continental silicic volcanic fields in the world. Silicic is used to describe magma or igneous rock rich in silica.

Experts say there is a one in 700,000 annual chance of a volcanic eruption at the site.

Wouldn't 99.9% of the airborn debris from an eruption go EAST, the direction the wind blows almost always? I don't understand their mapping. Even assuming upper atmospheric winds were blowing different directions, you'd still have a linear "fallout" pattern, not a huge circular blob. Northeast, Southeast, just some direction EAST.

Nothing/no one East of the rockies worth saving anyway.
