Roland Piquepaille writes "Two separate efforts using technology to protect people from earthquakes have recently been in the news. At the University of Leeds, UK, researchers will use nanotechnology and RFID tags to build a 'self-healing' house in Greece. The house's walls will contain nanoparticles that turn into a liquid when squeezed under pressure, flow into cracks, and then harden to form a solid material. The walls will also host a network of wireless sensors and RFID tags that can alert the residents to an imminent earthquake. Meanwhile, another team at the Washington University in St. Louis is using a wireless sensor network to limit earthquake damages."
