(CBS) -East Coasters who aren't accustomed to earthquakes: don't forget to duck, cover and check into Earthquakepocalypse* on Foursquare. After you Tweet and Facebook, that is.
The U.S. Geological Survey reported a magnitude 5.8** earthquake in Louisa, Va. on Tuesday afternoon.
A testament to the importance of technology as a source of breaking news, many people turned to Twitter, Facebook and even Foursquare to report the news. We're guilty!
Seriously, be safe out there.
Reactions from the Twitterverse...
New Yorkers are confused, according to @peteramckay "I'm in Lower Manhattan. Crowds of people have come out of office buildings, mulling around in street after feeling #earthquake."
Twitter user @LoreLoreL points out, "Eastcoast: *ground shakes*Earthquake!! OMG!!! 2012!! Westcoast: *ground shakes* you feel that? Musta been an earthquake. *goes back to work*"
Acting as the voice of reason, @PANdaNG tweeted, "LOL, people were worrying about Tsunamis? The earthquake wasn't based in the ocean."
