Where do you go when an earthquake hits? Under a table, or in a doorway. Although a doorway is the strongest part of a building, it doesn't protect you from falling debris.
Younghwa Lee has designed a door that can fold in the middle and offer you some protection. Because the door is sitting at an angle, any debris will slide off it instead of collecting on top of you.
