Twitter-Mapping the Japanese Earthquake

Twitter has a couple of interesting visualizations of tweets, replies and retweets to and from Japan immediately following the March 11 earthquake. “On Twitter, we saw a 500 percent increase in Tweets from Japan as people reached out to friends, family and loved ones in the moments after the earthquake. The video below shows the volume of @replies traveling into and out of Japan in a one-hour period just before and then after the earthquake.”

A second video, displaying “worldwide retweets of Tweets originating in Japan for one hour after the earthquake,” is also available.
