Worst I have been in was the 6.1 in 87. I was asleep at the time and had a stop sign mounted over my bed, needless to say I had a wicked bruise after that. I have no idea how many I have been through but about a half dozen were over 5. 4's are fun as they are exactly like a truck going by but you can feel it for a bit longer, 5's you start wondering if it is going to get worse and then it stops. 5.9-6+ becomes serious puckerage. Talked to some other people who are in the area who have been in California as well and it seemed lighter than what we remembered (like around 4.5). My guess is the difference in ground composition. Los Angeles and the surrounding area is pretty much swampland while here is more bedrock. The big concern there when the Big One hits is not only the earthquake itself but they have found that after some point on the richter scale the ground they have there because it is so soft becomes liquified. No matter how well you build buildings to be earthquake proof when the ground underneath undergoes that kind of transformation it is going to be bad. Yet people still move there...
