An earthquake early warning system using 250 Global Positioning System stations has in installed in Los Angeles.
"A new network of 250 Global Positioning System stations in California could provide rapid early warnings of major earthquakes...It is designed to sense movement on the San Andreas fault and the team is now waiting for an earthquake to test the system. The network will work by detecting movement between GPS stations on opposite sides of the fault...Taiwan already has an alert system based on the seismographs that detect shaking."
