In the wake of the Kobe quake, Japanese engineers took extensive measures to reinforce buildings and infrastructure. They installed rubber blocks under bridges. They spaced buildings farther apart to prevent domino-style tumbling. They introduced extra bracing, base isolation pads, hydraulic shock absorbers. A minute before the March earthquake, automatic seismic monitoring systems sent warnings to Japanese cell phones. Elevators glided obediently to the nearest floor and opened. Surgeries were halted. Videos from Tokyo show skyscrapers swaying gracefully, like cornstalks in the wind. Not one collapsed.

Likewise, the aftershock that struck Christchurch, New Zealand, this past February was deadly, but the astonishing part of that story isn’t that several of the city’s buildings collapsed; it’s that most of them did not. The peak ground acceleration—a measurement of how much the ground shakes—was immense, one of the highest ever recorded. Something like that would have flattened most cities. New Zealand’s strict and well-enforced building codes saved Christchurch from annihilation.
