China builds world's largest earthquake early warning system

The main construction task of China's earthquake early warning system has been completed, and final completion and acceptance is expected to be completed by the end of this year.

The country has carried out the construction of an earthquake early warning system since the 1990s and started building its earthquake early warning and instant seismic intensity reporting system in several high-stakes regions in 2018.

The system is the world's largest earthquake early warning system, making a leap in shortening the delivery of earthquake information from a minute to a few seconds after an earthquake starts.Expected to boost quake mitigation, the system can send alerts through various devices, including TVs, mobile phones, broadcasts and other warning terminals.
