I have been lucky to never experience a serious earthquake, the closest being slight tremors that I would likely not have even noticed if I had been outdoors or asleep. The video below was taken at an airport during the 2011 earthquake in Japan. It is quite terrifying. The tremors last for about two minutes.
What amazes me is that the person taking the video was so committed to doing so that they did not seek to run outside to avoid being injured if the balcony they were on collapsed, or to hide under something to prevent being hit by falling debris.
