Well, the Alaskan one certainly looks normal. We have a lot of little ones up here that nobody feels unless they're right on top of them. I'm always amazed everytime I look at the maps to see how many there are. Most of which I never felt or even heard about.
Having been through the big one, I guess I don't pay that much attention unless it goes longer than a few seconds. Not to say that I want to do that again!
