Are you seriously concerned about earthquakes? Perhaps you live right directly on top of a major fault line. Perhaps you are insane and paranoid. But either way, you're gonna need some protection, protection like this earthquake shelter door.
You see, if there's an earthquake and you just so happen to be near this door, you can fold it in half to make a crude shelter from falling objects. Once under there, if it manages to protect you while everything else falls down around you, there's a wind-up flashlight, drinking water and medical supplies in the doorframe.
Or you could just hide under a table. Either way, really.
