Possible Earthquake near Hampton Roads, VA

So I was sitting in the house and heard the sound of a low flying helicopter, and felt the ground tremble a little, which I thought were just percussions from the rotors. There's an air show at Langley AFB this weekend so thought a general was just flying in real low. Popped onto FB and saw this post from WTKR news.
