I experienced my first and only earthquake (5.8 magnitude) while visiting the holocaust museum in Washington DC. It was very out of the ordinary for the region and so as strange as it sounds, myself, my family and some other people present all thought the shaking was a part of the exhibit and simply carried on.... only for a security guard to come running in several minutes later to kick us out of the building. I think earthquakes can by easy to miss sometimes for those unused to them because they feel so mundane. Like everyone's experienced a certain degree of shaking before, heck the turbulence in a plane isn't much different. This obviously changes at higher magnitudes but really changed my perspective.
