I'm in the St. Louis area, and it was about 4 am that I felt the first quake. I thought it might of been a sudden windstorm or a tornado or something. It took a little to realize it was the earth shaking.
I'm the only person who's here at night, so I didn't have anyone to reflect on the issue with. It didn't seem to disturb anything, and nobody lost power - which I would have known since I'm the one that answers those calls.
There was another one at 10:30 that was the 4.5, but I slept through it hard. It would have had to of been much more potent then 4.5 to have woken me at my morning sleep.
