Nailsea / Violent shaking (MMI IX) : everything was destroyed and there were some injuries  
Chicago Illinois / Very weak shaking (MMI II) : 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.
