BEIJING -- A Chinese official said Monday that an experimental earthquake alert system, capable of sending warnings within seconds before a quake strikes, would be installed in quake-prone areas.
China was building a three-dimensional natural disaster monitoring system, including land monitoring, ocean and ocean-bed observation, and space-air-ground observation, it said.
China has built 937 fixed seismic stations and more than 1,000 mobile seismic stations, enabling quasi-real-time monitoring of quakes above 3.0 on the Richter scale.
In addition, 1,300 earthquake precursor observation stations have been established, as well as a mobile observation network of more than 4,000 mobile observation stations.
Seismological monitoring systems at the national and provincial levels have taken initial shape. A high-speed seismic data network composed of 700 information nodes has been built. A text message service to provide prompt earthquake reporting has been launched, according to the paper. |
