On June 17, 2019, a magnitude 6 earthquake occurred in Changning County, Yibin, Sichuan Province, and this earthquake surprised many people with the countdown to earthquake early warning.
After the earthquake, many places, including the main urban area of Chengdu, issued earthquake warnings in advance, and reminded the people to avoid danger in time through television, loudspeakers and other means.
Netizen: I want to cry when I hear the early warning sound, this earthquake early warning network is really powerful, I hope to popularize it!
Before the earthquake, many citizens were awakened by the earthquake warning. A citizen said, "Suddenly the alarm went off, very loud, very close." Counting down from around 40, 5, 4, 3, 2, 1... It started shaking as soon as it was over. ”
Many citizens, and even many people across the country, heard this earthquake warning for the first time. This countdown, cut through the night, is like a science fiction movie.
People rose up to record the countdown to the city.
The earthquake early warning network also released earthquake early warning tips through nearly 50 government media microblogs, including @Sichuan Public Security and @Sichuan Science and Technology.
The earthquake early warning system is a fully automated Internet of Things that enables a fully automated second-level response. Through the deployment of intensive earthquake early warning monitors in the main earthquake areas, when an earthquake occurs, the electromagnetic wave is used to "run faster" than the seismic wave, and before the earthquake causes damage, a fully automatic second-level response earthquake early warning warning is issued for the user a few seconds to tens of seconds in advance, and the people avoid danger in time to reduce casualties, and the emergency disposal of important projects to reduce economic losses and secondary disasters.
Studies have shown that 10 seconds of warning time reduces casualties by 39%; with a time of 20 seconds, casualties are reduced by 63%.
According to Dr. Wang Tun of the Chengdu High-tech Disaster Reduction Institute, Chengdu received an early warning 61 seconds in advance. 180 schools and 110 communities in Chengdu received early warnings, and evacuations were carried out in a timely manner. When the earthquake occurred, Yibin City received an early warning 10 seconds in advance, Luzhou City received an early warning time of 18 seconds, and Zigong City received an early warning time of 27 seconds.
As early as January 2017, when the Chengdu High-tech Zone openly solicited opinions and suggestions on people's livelihood projects for the whole society, some citizens put forward suggestions for strengthening earthquake early warning through the chengdu high-tech zone public information network.
At present, the TV earthquake early warning extends to all 13 cities and prefectures in all earthquake areas in Sichuan, covering 79 districts and counties, accounting for 60% of the earthquake areas and counties in Sichuan Province.
Seeing such an advanced early warning system, some netizens said that they wanted to cry when they heard the early warning sound, and this earthquake early warning network was really powerful, hoping to popularize it!
