This is the historic old Air Force One plane used by President Ronald Reagan. It is now on display at the Reagan Library in Simi Valley, CA.
The AF1 exhibit at the Reagan Library is only about a year old. I would have to assume the architects and builders used the latest techniques to strengthen the exhibit against earthquakes.
As someone who lives in Southern California, I'd be more worried about the brush fires that sweep through those valley areas much more frequently than significant earthquakes do.
