A few years back something similar happened to us. I thought my kids had somehow knocked over a heavy piece of furniture, like our dining room table or couch.
Turned out that it was a gas explosion in a house about a mile away. The owner had left the oven gas on and the house filled up and blew to smithereens.
Super creepy lurker from MM, here. If I am remembering TLH threads correctly, I live in the county south of you and I felt something, too, last night around 10:30 or 11:00. We were going to bed and it felt like the whole house shook for just a second or two. No idea what it was but I am somewhat comforted that people in another county felt it and I won't have to fear falling into the earth during the night. If it IS a sinkhole, it's a damn big one.
