Felt more like a 6

The various earthquake sites tell me that was a magnitude 5.6 I felt a few minutes after eight o'clock. The whole house was shaking quite noticeably, and a couple of little things fell off the shelves. It went on for quite a few seconds, and grew in intensity, so I stood in the doorway away from things that could fall on me. From what I can figure out from the earthquake sites, the epicenter was within twenty miles south of me.
