According to the China Seismological Network, a magnitude 4.0 earthquake occurred in Chengdu Dujiangyan City at 14:4:41.
   The company officially applied the earthquake early warning system in mid-March this year, and it is also the first place in the country to apply earthquake warning to the hazardous industry. It is understood that the company is 32 kilometers away from the epicenter of the earthquake. When the earthquake occurred, the early warning system provided a warning time of 5 seconds.
   Wang Lan, director of the Sichuan Provincial Key Laboratory of Earthquake Early Warning and director of the Chengdu Institute of High-Rise Disaster Reduction, said: "The green light warning is the arrival of earthquake waves, but it will not cause too much impact on production, but it will remind the pre-judgment; The earthquake wave will have a large and large impact on the production line, and an emergency warning must be activated immediately."
Wang Wei told reporters that the system also has a linkage device. When the red light warning mode is activated, the chemical-specific warning receiving terminal will give a control signal, and the chemical enterprise solenoid valve will be automatically closed or opened. In this way, when destructive seismic waves hit, the hazardous chemical production line has been able to prepare emergency plans in advance to ensure the safety of hazardous pipelines such as oil and gas pipelines and chemicals.
Earthquake early warning refers to the technology that when the earthquake occurs in the epicenter, the destructive seismic wave uses the principle that the electric wave is faster than the seismic wave before reaching the early warning target, and the alarm is issued several seconds to several tens of seconds before the disaster.
Since 2011, Chengdu Earthquake Disaster Reduction Bureau and Chengdu High-tech Disaster Reduction Research Institute have taken the lead in applying the self-developed earthquake early warning technology in China, and built China's first earthquake early warning network, covering an area of ​​700,000 square kilometers. The ability of major projects and industries to provide earthquake warning information. At present, the earthquake early warning technology has been applied in the densely populated areas such as primary schools, communities, office buildings, etc., and has achieved good disaster reduction effects in the 7.0 earthquakes in Lushan.
