Quake network under construction

Sensors being installed in Sichuan and Yunnan - China's most active areas

China has begun building a monitoring network in seismically active regions in Sichuan province and neighboring Yunnan province, according to the Institute of Care-Life, a key earthquake early-warning laboratory.

About 2,000 monitoring stations will be built in the two provinces in the next year or two to form an underground cloud map monitoring network.
