Check out these visualizations designed by @miguelrios. From Twitter's blog:
"On Twitter, we saw a 500% increase in Tweets from Japan as people reached out to friends, family and loved ones in the moments after the March 2011 earthquake. This video shows the volume of @replies traveling into and out of Japan in a one-hour period just before and then after the earthquake. Replies directed to users in Japan are shown in pink; messages directed at others from Japan are shown in yellow."

The second video "displays worldwide retweets of Tweets originating in Japan for one hour after the earthquake. Senders’ original Tweets are shown in red; Tweets retweeted by their followers in the hour after the event are displayed in green."
