This.

They are also quite frightening. I know this because I had a few pop up in my dream last night and that **** is scary as hell when you are thinking "well there's a tornado coming right at me".....

Personally though, I find the Tunguska Event fascinating. Here we have an explosion with about 1000 times the force of Hiroshima and it was COMPLETELY NATURAL! It's a good reminder that Mother Nature is no slouch herself and can cause serious damage if she wants to.

Tornadoes, I've been in 3 of them and in all of them I was amazed.

Black holes, considering they defy everything we know.

I'm fascinated with Solar Flare - and no, not because of that Nicholas cage movie.

If I had to choose one on earth, probably volcano. When Mount Pinatubo in P.I. erupted in '93, I was 7 years old. My town was a few hundreds of kms away, but we felt the tremors, saw the smoke clouds and I remember a lot of ash raining down. We weren't afraid of lava or anything because we were far enough, but more of the after affects like in agriculture, people going crazy in fear, etc....

That really cold stream of water-ice-thing. Forgot what it's called right now, but it's so scary.

edit - it's brinicle

the quantum zeno effect, i cant explain this mind blowning phenomena.
