Heavy causalities in Turkey-Syria earthquakes highlights urgency, necessity of global early warning system: leading Chinese scientist

[...]

Wang, who developed an earthquake early warning (EEW) system in China, said that the disaster is a reminder to all governments in the world on the significance of setting a global network on early warning. China, with its experience in building world-leading EEW, can share the international community with its experience and technologies. 

"With an early warning of several seconds to 60 seconds, the death toll in an earthquake can be reduced by 30 percent," Wang said, noting that if China had set such a system before the Wenchuan earthquake, Beichuan, a severely-hit county, would have been afforded an extra 31 seconds of "live-saving" time meaning the total death could be reduced by 20,000 to 30,000 and more than 20,000 heartbroken families could avoid the pain of losing family members.

According to Wang, after the Wenchuan earthquake, China has focused on developing early warning technologies and has set the world's largest earthquake early warning system which has the fastest speed and the most accuracy. It covers 90 percent of the population in earthquake-prone areas. 

China's real-time monitoring system can capture seismic signals as soon as possible and provide early warnings released through mobile phones, TV, radio and new media. A total of 800 million televisions and cellphones have already installed the earthquake early warning function, said Wang.
