When the Washington Post's fifth floor newsroom began to sway one slow afternoon last August, my colleague Joel Achenbach barked, “That's an earthquake.” It was good to put a name on this strange movement; I had never felt anything like it. The building swayed, then shook. One reporter ducked under his desk and I started to do the same. Before I could scoot my rear end to safety though, the shaking stopped and the building settled. The great East Coast quake was over.
