Obviously, being prepared for an earthquake is the best way to survive one. But what about your home? Can the windows, walls, foundation, and roof survive the shake, rattle, and roll that comes from a wild tremble?
An earthquake proof house might be the answer. Engineers have designed windows that have a bit of "give" to them around the frame, meaning that they move rather than crack in the event of an earthquake. The walls are much the same way, with a bit of space that allows movement between the window frame and the wall itself. This eliminates stress points and results in a sturdier house during the big shake.
It is all tested on a "shake table," or a structure that mimics the power and intensity of an earthquake in a laboratory setting. Entire houses can be constructed on this shake table and then exposed to the pounding of an earth moving event. Shake tables are used extensively in Japan, where earthquakes of incredible magnitude are a common occurrence.
Structures in Japan, from the most modest houses to the largest skyscrapers, must be able to withstand the shaking and swaying of an earthquake. Older, wooden buildings can easily collapse when the shaking tears them apart, or when they waves of energy in the ground liquefy the hard soil beneath the structure. Knowing these dangers, Japanese engineers have worked steadily for decades to create new building techniques for construction, including methods of creating a foundation, erecting walls, and installing new roofing.
If you are looking into purchasing a home in Japan or want to remodel your old one, keep the earthquake building codes in mind. Don't make the mistake of assuming your home is sturdy enough to withstand an earthquake! The constant shaking from underneath your foundation can cause even the sturdiest home to collapse. Remember, the key to staying upright is in the amount of "give" a home has.
So the next time you feel that trembling beneath your feet, you can rest assured that your modern home has the ability to roll with the punches!
