Inspired by http://xkcd.com/723 and described at http://www.iq.harvard.edu/blog/netgov/2011/08/tweetquake.html -- A heat map of the frequency of tweets mentioning the word "earthquake" in the 5 minutes after the Virginia earthquake on 08/23/2011. The locations are self-reported by Twitter users and may be erroneous. The spread of the earthquake is approximated to be 4000 m/s.

  • Thumbs up if you saw your county light up!

  • Thumbs up if Terry Tao took you here!

  • this is why the internet is good and any censorship is bad
