At 5:59:23 pm CDT, a magnitude 3.0 earthquake occurred, and the epicenter was 5.0 km (about 17,000 feet, not that deep for an earthquake) between Huffman and Trussville. 12 seismic stations detected the earthquake, and over 40 people have reported it to USGS.
I was here in Trussville, the dog started barking, and then the house shook pretty decently for 3 or 4 seconds…similar to what I felt in the April 2003 earthquake near Fort Payne. Difference here is the 2003 quake was stronger and farther away, I was almost sitting on top of the center of this one! Researchers are still looking into how dogs may sense an earthquake before it happens. Then again, he could have been barking at anything.
Added late: I have added a seismogram of the earthquake from Huntsville (James posted it this evening):
