Yes. It was an earthquake. The Great Brooklyn Earthquake of 2011 (which actually had its epicenter Northwest of Richmond, Virginia, but whatever, solipsism is a fair response to a natural disaster). 5.8 on the Richter Scale, and a 7.8 spike on Twitter. (For comparison, the death of Osama bin Laden was a 9.2, and whatever is going on with Will Smith and Jada Pinkett today is a 3.7.)
Love save Brooklyn.
