Philadelphia / Very weak shaking (MMI II) : Not sure if just a coincidence or not, but I was woken up recently by my whole bed shaking and could feel both the walls and floor tremble. Went on for at least two minutes before stopping. Could be some weird construction but it's 1:48am est so seems unlikely and feels like a previous earthquake experience I've had
