Earthquake Early Warning System Pioneered in Japan

Tomo Hiratsuka writes "After recent destructive earthquakes around the world, Japanese scientists have come up with an earthquake early-warning system that uses sensors and various technologies, including iPv6, to provide up to a minute's warning, which could make a lot of difference, especially in the event of a tsunami. Bizarrely, one of the warning methods even involves networked photocopiers, believe it or not."
