We have always had occasional small tremors but this one was big, for us. I read somewhere that they had upgraded it to a 5.5. I thought it was that type of thunder that rolls in waves at first but both my little house dogs jumped out of bed and started running and barking. The outside dogs were barking too. They don’t bark at thunder. From the map of where it hit the epicenter was close to us. I’m in Athens TN.
Several years ago we had one that was bad enough that it sent me and my work office chair bouncing across the room.
No it wasnt upgraded. Whatever fool said that doesnt use the USGS site
