Protect Your Bunker From Earthquakes

For surviving 2012, a bunker is your #1 bet. If you design it well, and locate it well, it is almost perfect:

• on a clear hill, with nothing that can fall on top of it
• far enough from the coast to be safe from the tallest tsunami
• deep enough in the ground to be safe from radiation
• sealed and filtered
• a safe distance from volcanoes
  
• hidden from humans

Possibly the hardest to protect yourself from is earthquakes, which can happen anywhere, and in a SHTF scenario could occur everywhere. Researchers might have found an effective, and maybe even cost-effective earthquake barrier:

Researchers say they have found a way to make buildings essentially invisible to earthquakes. If perfected, the technique could protect skyscrapers and homes alike from even the most devastating temblors.

Earthquakes, sunlight, and radio all share a common factor: They propagate via waves. The only difference is that earthquake waves are so powerful--their energy can equal several nuclear bombs--that they literally shake apart rigid structures.

Researchers at Aix-Marseille Université in France and at the University of Liverpool in the U.K. have now developed a barrier that keeps buildings from feeling these waves. They took a cue from stealth aircraft, which employ combinations of specially shaped and fabricated materials that absorb radar signals and deflect them off course. For earthquakes, the concept is the same: Using computers, the team modeled a device composed of layered, concentric rings of plastic, copper, and four other materials of varying flexibility and stiffness--all designed to harmlessly deflect earthquake waves.

Basically a fence in the ground, made from easily obtainable materials. It's a great concept for protecting buildings in earthquake-prone regions, but even more suited to bunker builders :)
