Yep - definitely. I was in bed, reading, with headphones on (Robin Guthrie and Harold Budd). My bed began to shake back and forth. Initially I thought it was my house-mate back from the pub (we have bouncy floor-boards), but it got stronger. I took the headphones off, and could hear a mild rumble and saw that my synth racks and angle-poise were all shaking quite violently. Then it stopped and the whole house was eerily silent.
The tremor went on for about 5 or 6 seconds - really weird and quite spooky, and my first experience of an earthquake (who'd have thought it would be in London?!!)
