'Invisibility' cloak could dampen blow from earthquakes

Researchers at the University of Manchester have proposed a structure that would protect a building by making it “invisible” to seismic waves.
Metamaterials can create an "cloak" buildings from the seismic waves of earthquakes to protect them.
Researchers say giant rubber cylinders coated with special wave-scattering materials could act as a "seismic waveguide" and dissipate the punch from earth quakes.

Which shock waves would this be most effective against?
Where might this be useful?
Are there any draw backs to this idea?
