	<span lang=\"EN-US\">We study the analogy between the
linear elasticity theory equations and classical Maxwell equation with chiral
effects and we propose a new method of an earthquake-resistant design to
support conventional aseismic designs using acoustic metamaterials. We suggest
a simple and practical method to reduce the amplitude of a seismic wave
exponentially. Our device is like an attenuator of a chiral seismic wave.
Constructing a cylindrical shell-type waveguide that creates a stop-band for
the chiral seismic wave, we can convert the wave into an evanescent wave for
some frequency range without touching the building we want to protect.</span><span lang=\"EN-US\"><o:p></o:p></span>
