Large-scale metamaterials could combat earthquake shocks

By Ian Randall

Future cities could be protected from destructive earthquakes using large-scale metamaterial shields to dampen seismic waves, according to new work done by researchers in Europe. The team used 3D modelling to demonstrate the potential of the shields, which are made of arrays of cavities dug into the ground.

Of all natural hazards, earthquakes are perhaps the most catastrophic – they account for more than half of all disaster-related mortalities and have the potential to cause billions of pounds worth of property damage if they strike major population centres. While buildings and other infrastructure can be individually engineered for earthquake resistance, such measures tend to be less effective against large quakes and difficult to implement post-construction, especially within historic buildings.
