These joints of steel can move without breaking. Also, to prevent property damage, architects now design buildings so that the building's columns and horizontal beams are of equal strength, and vertical support columns are inserted deep into solid soil. In addition, many new houses have relatively light roofs and strong walls. Concrete pillars for highway bridges that previously only had steel rods inside are now enclosed in steel.

Certain birds, like pigeons, also seemed to be especially noisy and were reported to be flying in unusual patterns before the earthquake. Perhaps most interesting, and most easily measured, is a chemical change in ground water before a quake. Experimental data seem to indicate that the amount of radon (Rn) in the water under the surface of the Earth waxes before an earthquake.
