I just had the earthquake discussion a few weeks ago with a friend on Facebook who lives back in tornado alley. I've lived in California almost all my life with the exception of a few years when my dad was still in the Air Force and we got transferred around a few times. So in all those years living in California, the worst earthquake I ever remember feeling was in 1968 when dad was stationed at Scott AFB, Illinois. Not only did we have a pretty big earthquake, but we also had to run hide in the basement there when the tornadoes came.
