Announces earthquake early warning prototype

China Earthquake Administration announces the construction of over 5,000 seismic stations (especially in the Sichuan province) for earthquake early warning, combining seismic and critical new data sets to improve rapid earthquake notification. The project will provide immediate useful information about the intensity of earthquakes with magnitude five or higher within two to five minutes after the earthquake. Seismic intensity distribution maps are obtained within in 15 minutes, while all information regarding casualties, affected areas, economic damage will be given 30 minutes after the earthquake occurs.
