Don’t want to alarm anyone, but we’ve just had another aftershock — this was a pretty strong one, shaking and vibrating the lamp on my work table and the floor under my chair for a good ten seconds or so, or long enough for me to wonder if it was going to get stronger and back to what it was on Tuesday. But all is quiet now. My dog and cat slept through it.
UPDATE: It registered 4.5, the largest since the 5.8 quake itself.
