No damage around me in Arlington VA, as far as I can tell. I was on the 9th floor of an office building when it happened -- lots of shaking, I stood in an office doorway until it stopped, then the fire alarm went off and we all evacuated. After a while they let us back in.

My neighbor says some stuff fell off her shelves at home, which is a few miles from here.

I have heard about a burst water main at the Pentagon, a partial roof collapse at a Best Buy in DC, and structural damage to a garage at National Harbor in Maryland. Also damage to the National Cathedral in DC. But I have seen no details about any of this, so take it with a grain of salt.

My cousin lives in Louisa, VA, very near the epicenter, and works near Richmond. I've texted his mother (in NY) and sent a facebook message to his sister (also in NY) but haven't heard anything back yet. Hopefully everything is okay. I don't have his phone number to try to contact him. He is a prison warden so if he was at work they probably went on lockdown or something like that.

BTW, twitter is THE source for breaking news. By the time we had gotten outside our building, I was seeing news about the earthquake.
