Ready for the Quake
Claire Berlinski looks at preparation - and lack of preparation - for earthquakes. An excerpt:
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.
