Via Boing Boing comes this from the Virginia Tech geology department:  “East of the Rockies, an earthquake can be felt over an area as much as ten times larger than a similar magnitude earthquake on the west coast.”

So that explains that. My first earthquake, for what it’s worth. And I started a new medication yesterday so my first thought was, “Well this is a weird side effect.” Then everyone else was all, “what the hell was that?”
