The most 'interesting' earthquake I have ever been in was in Tokyo. Our office in Tokyo is on the 13th floor of a building, and it was a holiday over there, so two other guys (from my office here) and I were the only ones in the whole building except for security. We were in a corner office and I thought 'wow, its windy outside', only to realize no windows were open. Then I realized the shades were swaying and the shades in the building across the street were swaying. It was just weird having my stomach lurch that much without any control over it at all. The other times we had earthquakes over there was when I was sleeping and didn't notice, apparently.
Earthquakes are just... frightening. I have never felt like I had no control over anything like that before, or since.
