So a mild earthquake feels like a gentle swaying on a boat. I'd never felt an earthquake before. I was sitting at my desk, just after lunch, when there was a strange sensation of motion, almost like being gently rocked. Nothing fell. But the world felt just ever so slightly liquid. I thought it was some kind of constrction - we used to get occasional blasts from deep excavation for water tunnel three, It didn't occur to me to duck and cover. And then it was over.
It certainly added a bit of excitement to the afternoon. I was surprised the epicenter was so far away, in Virginia.
