Quick rapid movement - almost earthquake like in uterus

Has anyone else had some quick rapid movement in uterus you think there is no way baby can kick that fast?? Last night I was sitting on the couch and got some seriously fast movement I looked at my husband in shock and said it felt like a earthquake just happened in my stomach. It even made me feel like the seat below me shook!! It only last but 5 second and my little man has been moving like normal but it did worry me a little. I have a call in to my doctor to ask them but in the meantime I made the mistake of googling it.
