Evan Reis, a co-founder of the U.S. Resiliency Council, a nonprofit organization, says the biggest impediment is that unlike in Japan, buildings change hands frequently in America and the developers who build them do not see the incentive in making them more robust. Base isolators are like shock absorbers between the building and the ground motion, letting a building slide back and forth while remaining upright during a quake. Chile, China, Italy, Mexico, Peru, Turkey and other countries vulnerable to earthquakes have adopted the technologies to varying degrees. at San Franciscos Exploratorium, one misconception about building stability is that a skyscraper would be more dangerous than a smaller office building, but in fact, the opposite is often true. Japan, of course, still has many vulnerabilities, some of which were made clear when the 2011 Tohoku earthquake created a tsunami that breached sea walls, killing an estimated 16,000 people and spreading radiation from a damaged nuclear reactor.
