Secondary ash zone.

In that scenario between the ASH and blast, most wiped out will be the GOP...God help us. Anyway to move yellowstone to say off the coast of San Francisco or further east to say Crapcago??

Oh yay...

I’m smack dab in the Secondary Ash Zone.

Boy, that’ll be fun...

That doesn’t look too bad. It barely touches my Tennessee international ocean front seaport that will open any day now as global warming raises the sea level.

You call that a natural disaster? Almost everyone east of the Mississippi will have to wait around to be killed by a different cataclysm...

Don’t know if this would be applicable, but using NukeMap, I detonated a 100MT device 25 meters above ground, making a crater 2.5 KM diameter by 420m deep.

Prevailing winds took the fallout east north east across Montana, North Dakota, and into Canada west of Winnipeg. I assume that the volcanic ash fallout plume would take a similar direction.

The map does not seem to take into account prevailing winds.

I live at the bottom of the “K” in Kill Zone.

Have a pocked-marked lava ‘stone’ from the last eruption...it was excavated from about 30’ down during a building project.

Really cool!

Bear in mind this chart mostly relates to immediate threat from the ash for suffocation, or a bit later structures suffering roof collapse.

Prior large ash eruptions and sulfur emissions have blocked enough sunlight to drop temps and otherwise harm crops and vegetation. Likely a decade to clear the sky.
