French scientists are testing ways to use refraction (i.e. changing the direction of vibrations) in order to shield large cities from earthquakes.   Image © wikimedia

While the process is still experimental and theoretical, the early indications are positive for the mitigation of earthquake damage.  The only catch: the massive force and vibration has to go somewhere.  But the process may prove useful in cities such as Los Angeles, where there is a nearby desert.
