Metamaterials could mitigate earthquake effects / I metamateriali potrebbe mitigare gli effetti del terremoto Segnalato dal Dott. Giuseppe Cotellessa / Reported by Dr. Joseph Cotellessa Large-scale metamaterials can attenuate the energy and amplitude of harmful low-frequency vibrations associated with seismic shocks. This is the conclusion of a European study published in the New Journal of Physics that proposes the use of metamaterials in regions threatened by earthquakes. The metamaterials in question are artificial structures that exhibit extraordinary vibrational properties and the study, carried out by a team using detailed computer simulations, shows that large-scale metamaterials can attenuate the energy and amplitude of the low-frequency vibrations that earthquakes deliver. Many large, modern structures including bridges and office blocks are protected against earthquakes through vibration isolation strategies that can be difficul
