Here is a very interesting pattern of twitter activity just right after the big earthquake that hit Japan on 11th of March 2011.
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.
