I bet some folks back there are ready to move. When the Earth starts shaking it kind of does something to ones psyche. You no longer feel safe.
I remember the first one I went through, I was in California. Scared the heck out of me. That was back in 1969. Took me weeks to get over that one.
Here in Alaska, we have two or three a week here that I only feel when I am in bed. Little ones usually below a 5. You only feel them if you are in bed, or sitting down. Most people don't feel them because they are driving, walking, or actively doing something.
I keep thinking about the New Madrid fault along the Mississippi. What is going to happen when it goes. Scientist say it's overdue, and that it should be a real shaker.
Then every once in a while we have a good shaker up here. Last real one we had that got us going was a 9.4 back around 1999 or 2000. I was shopping in the Commissary at Ft Wainwright with the wife. She panicked and tried to run out of the building. I grabbed her and sat down beside the freezers. That way if the roof fell the freezers would provide a space to survive. This one shook the pipeline and caused needless concern over it's well being. Broke several windows, and cracked walls in my house. It's strange seeing concrete floors with waves running along like they were made of water.
