Chicago Illinois / MMI II (Very weak shaking): Lasted for about a minute. Shaking was weak, but noticeable since earthquakes don't occur very often in this part of the world. Many people who were sleeping didn't feel the earthquake, but others who were awake happened sometime between 12:35-12:38AM local time.
