For a seismic wave to travel the 230 miles from Washington D.C. to New York City, it takes approximately 30 seconds. That's roughly 27,600 miles per hour.
It only takes 25 seconds for someone to feel the ground shake, and post a tweet that says "I think we just had an earthquake", that can be read by someone in New York.
That is exactly what happened last Tuesday when a 5.9 earthquake struck near Richmond, Virginia. When buildings shook near Washington Tuesday afternoon, the internet exploded, primarily on Twitter and Facebook. Twitter claims that readers in other areas were aware of the coming quake via their site before local seismographs registered any readings. They're so proud of it, in fact, check out their new promotional video:
Twitter announced Wednesday that the D.C. earthquake created more site traffic for them than the death of Osama Bin Laden, and tied the level of traffic that they saw at the time of the Japanese earthquake and tsunami in March. This tells me one of two things. Either Twitter has quickly gained a large number of users, or Americans seriously have their priorities fucked up.
As an interesting side note, Eric Fischer created an animated map of the earthquake related tweets that afternoon. The green dots represent earthquake related tweets. Gray dots are tweets about other topics. During the 28 second piece, each frame is one second. The entire piece represents 12 minutes of elapsed time.
