Thanks for posting this. I've heard some crazy things about how much the Earth moved, and this sets it straight.
One of the oddest things I'd heard was that the Earth slowed down it's rotation. Usually when an Earthquake happens, there is some settling, and the Earth compacts [not expands], and so as the ice dancer pulling in her arms on a spin, the Earth speeds up. In this case, the speed-up is about one millisecond/year, which is pretty small compared to the general slow-down from the tides, and so the next leap-second will mostly likely not be delayed by this.
