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

Spread of information

  1. Wow! So interesting! Internet is really connecting people.

  2. Internet, such an amazing device

  3. Doesn't look like there was much of an increase in the number of twitter-folks, but instead just an increase in the number per person. I bet we'll see that trend again next disaster

  4. Simply amazing, I wonder what software/tools are used to visualize twitter traffic like that. This shows we really are becoming one global consciousness via the internet.

  5. Twitter can be useful it seems.

  6. Honestly, I just cant get into the whole Twitter scene. I am more of a barker! Great blog, I'm going to follow!
