I woke up in the middle of the 4.4 quake that is bolded. It was very weak here at my house, though it was strong enough to wake me up I guess. It lasted about 4-5 seconds and seemed like a rolling quake as there were just intermittent shakes for a few seconds. I went to check the USGS website and didn't see anything reported yet but it showed up a few minutes later confirming my suspicion. I just love quakes (unless they trigger tsunamis of course).
