We can now 'cancel out' earthquake waves using nothing more than a set of portable, high-tech bricks.

The Takeaway
Usually, to protect a building from earthquakes, you have to dig up the entire foundation and install massive rubber isolators. These 'Seismic Bricks' are different: they’re prefabricated, portable resonators that can be 'clamped' around a site to block 95% of low-frequency earthquake energy. They work like noise-canceling headphones but for the ground, creating a 'bandgap' that seismic waves simply can't pass through. This makes it possible to protect existing critical infrastructure—like nuclear reactors or hospitals—without having to rebuild them from scratch. It’s a literal 'shield' you can put around a building to make the ground beneath it stay still while everything else shakes.
From the abstract
Practical implementation of seismic metamaterials presents significant challenges due to the possibly large dimensions of the unit cells needed. There are also challenges in retrofitting and installation including the preparation of a suitable foundation, compaction of the soil, arrangement of a concrete bed, and excavation down to the rock bed during the construction process. This paper discusses the development of a novel clamped Seismic Brick metamaterial concept with a realistic resonator si
