I just experienced my first earthquake about 10 minutes ago! The whole house was rumbling. My first thought was, who is washing the clothes now? It was like the washer was on spin cycle and it was off balance. But, it felt a bit more powerful than that, then I thought… earthquake! The rumbling lasted, I would say, 15 seconds, then gradually died off. It wasn’t enough to move anything in the house, but it sure was wild experiencing one in a city (Atlanta) not known for earthquakes.
