The issue with earthquake-proofing a constructing is that it often includes grafting on a variety of help — not likely an choice with historic buildings or different notably delicate buildings. Komatsu Seiren Material Laboratory may need a greater means, nevertheless. Its carbon fiber-based mostly CABKOMA Strand Rods can shield a constructing towards quakes by tying the roof to the bottom, ensuring that the entire constructing strikes collectively — and thus stays collectively — throughout a tremor. The fibers are each very robust and really mild (you’ll be able to simply carry a 520-foot strand by your self), so it is extra like draping spiderwebs over a constructing than anchors.

As you may need gathered simply by wanting on the photograph above, the know-how has its limits. It will not work for tall buildings, or these in dense city areas the place there’s merely no room. That is extra for mid-measurement buildings which have loads of free area. All the identical, it may be the important thing to saving lives in areas the place typical bolts and braces simply will not work.
