Seismic cloaking
WebNov 21, 2016 · Metamaterial ‘invisibility cloaks’ have already been used to make very small objects invisible to the eye by redirecting light waves. Now, large-scale versions could be created to emulate the resonance of trees and make buildings ‘invisible’ to earthquakes. Diverting earthquakes WebJun 7, 2024 · A promising way to cause a modification of the seismic disturbance is to create complete artificial anisotropy by implementing geometrical elements, full or empty, in the soil [ 11 ]. The physical process is the interference of waves (body or surface waves) scattered from surfaces or objects.
