Personal Messages From Japan

This was brought to my attention by @ChrisRotvik, who has been doing some volunteer work with the Red Cross. The video comes from the Twitter blog, where they shared the following:
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. Replies directed to users in Japan are shown in pink; messages directed at others from Japan are shown in yellow.

There’s another video on the blog that shows retweets.
Pretty incredible, huh?
