Earthquake shakes up social media users

A 5.9 magnitude earthquake centered in northern Virginia occurred at about 2 p.m. Tuesday, causing buildings to mildly shake across the northeast United States.Within minutes, users of Facebook and Twitter reported their incredulous thoughts that a moderately-strong earthquake actually struck the northeast, an area mostly immune to moderate, not to mention strong, earthquakes.The social media users also checked on family and friends located nearer to the earthquake’s epicenter. The quake was felt from New York City to North Carolina, with many in Atlanta and northern Georgia reporting feeling the tremors via Facebook.
