It is common knowledge in earthquake-prone places that a door may be your best bet for nearby safety if you cannot get to more-solid ground. Since doors are basically everywhere, it is a good place to start. That is where this design begins, but not where it ends.

Taking that everyday idea and reinforcing it, Younghwa Lee (MA Design: Product and Space design student at Kingston University) created a prototype door that anchors to the frame at the base, but folds down to provide protection from above on demand.

The slope both provides a table-like overhang and deflects debris due to its angle, rather than allowing it to gather (and potentially buckle the shelter from) above. Each doorway is designed to shelter up to two people if needed, and comes complete with a small cabinet with emergency items like flashlights in the event of power failure and for dealing with other post-quake contingencies.
