I've been through a dozen different tornados and they're not pleasant. I think it's because they're so random and hard to predict. Hurricanes you see coming; Volcanoes are usually pretty obvious as well, but tornados just come and go in a blink of an eye and destroy so much.
I was also in a pretty good sized earthquake, but since it was so far away it only shook things for a few seconds. Pretty scary, but nothing harmed.
(edited after I re-read the question)
We had a pretty big tornado around here about 4 years ago. I was living in a shoddy little apartment complex and my roommate and I had to go out in it to check on some friends. It wasn't that bad when we left, but it got real dark real quick. I drove around several sharp turns and found big fricken' trees crossing the road.
Once we got to our pal's house we sat outside and watched the lightning on his front porch (the power was out and we had our little weather radio) Then we saw the biggest, darkest, blackest wall of clouds I think I've ever seen. It looked like it was coming right at us, but it was actually taking a more parallel route.
Once all the shit was over we started to drive through my pal's neighborhood; strange thing is we found out a smaller tornado had come through the neighborhood while we were out screwing around on the porch! It knocked out a couple of houses and totally demolished the housing complex behind my pal's house. We assumed the tornado the radio was warning us about was the one we could see!
Now everytime we have a "severe thunderstorm" I hightail it to the basement and find me a corner to hole up in.
