Strange behavior and earthquakes
The following from All Shook Up: Mapping Earthquake News on Twitter from Virginia to Maine | SocialFlow Blog.
"The proper response to an earthquake? Run, scream, take cover?… no wait, Tweet!
"On Tuesday, the denizens of the East Coast had exactly this choice, and they responded by flooding the interwebz with messages: startled, mundane, humorous, informational. And it happened fast. Seismic waves travel at 3-5 km/s, communication signals in fiber optic cables move at a speed of 200,000 km/s [as this XKCD cartoon brilliantly notes]. Tweets do take time to compose, but significantly less when you’re tweeting “EARTHQUAKE”!
"We thought you’d like to see some of the data behind it. The visualization below replays the spread of earthquake related Tweets across North America, from the moment the epicenter hit Mineral Virginia (1:51PM) on August 23rd through its spread across the East coast and the South."
