Tornado or volcano?

I also posted this in the forums, but I know there are a few folks (I’m going to guess it’s a number that roughly equals 99.759% of the internet) who don’t bother with the forums, so I’m gonna blawg it too.

And the answer is… VOLCANO!

My hat’s off to the photographer. You’re the man now, Chile dog. You got National Geographic’s attention and everything.
