Same for me in Fairfax, VA and my daughter in Suitland, MD.
My office building was literally shaking and swaying - windows shaking and rattling. It was very intense - people were scared and the evacuation sirens started going off. The building was evacuated and we were not allowed to return except to get our stuff and leave. No cell phones, no fire department, no emergency service vehicles. A wake up call - if something happens, you are on your own.
