Interesting psychological note - I work in a large place where people aren't always too terribly friendly with each other. After the quake, I noticed more smiling faces and got more "hi, how ya doin?" greetings in a couple hours than I have in the past couple of months. Interesting how traumatic or near-traumatic experiences can drastically change people's attitudes and perceptions. Probably a stark reminder of how insignificant and powerless we are in the face of nature - especially since, geologically speaking, this was nothing more than a small belch and a little dribble down Gaia's bib.
