Most modern buildings and infrastructures are not designed to resist 8thmagnitude earthquakes, for which studies on phononic crystals and localresonators reported so far are not particularly suited. We report a type ofall-metallic decorated membrane resonators as deep subwavelength vibrationdampers, which are modeled as meta-soil, that can block and even totally absorbunderground seismic waves up to 8th magnitude earthquakes. Transmissionattenuation exceeding 20 dB and absorption up to 98 % are numericallydemonstrated for 1 Hz Rayleigh waves by a dozen rows of vertical undergroundwells filled with the meta-soil. A scaling law in the same form as the massdensity law for airborne acoustic waves has been analytically derived andnumerically verified.
