Researchers at the University of Hong Kong have made an "earthquake cushion" that could help developing countries that would otherwise fall short on earthquake mitigation. The Geotechnical Seismic Isolation System is a mix of shredded rubber tires and soil that can be used to reduce shaking by an average of 50%. "It's a lot like the airbag in a vehicle, which prevents occupants from striking the interior objects," says lead researcher Dr. Hing-Ho Tsang.
