The construction of earthquake warning network in Beijing-Tianjin-Hebei region
There have been many strong destructive earthquakes in the Beijing-Tianjin-Hebei area, causing serious casualties and economic losses.
As one of my country’s three major urban agglomerations, earthquake disasters in Beijing-Tianjin-Hebei region is very important, and earthquake prevention and disaster reduction has extreme importance.
In order to minimize earthquake disaster loss, provide a solid seismic security guarantee for the development of Beijing-Tianjin-Hebei, China Earthquake Administration deployed the Beijing-Tianjin-Hei Earthquake Early Warning Network. Since 2012, Tangshan City construction earthquake early warning test network, in the later, Shijiazhuang, Zhangjiakou, Qinhuangdao and other places have also built a seismic warning demonstration network, achieved good results, and play a model role in the national earthquake warning engineering. In 2018, the national earthquake warning project was built, and the Beijing-Tianjin-Hebei region was used as a first-line examination area and accelerated the construction of earthquake warning network. The earthquake warning network in the Beijing-Tianjin-Hebei region, in accordance with the principle of "one network, a table, a set of mechanisms, one" result, unified station network access layout and quantity, unified station parameters, unified data processing parameter settings and processes, unified Published the data source, jointly introduced the Beijing-Tianjin-Hei earthquake warning network test operation, and promoted the establishment of a clear border of the duties, the unity of observations, the operation and maintenance supervision, and the business operations collaborative.
Beijing, Tianjin, and Hebei have also built three regional earthquake warning centers, deploying early warning information processing, decision making, release, intensive quick report system, and opened the full chain of the earthquake warning information quickly handled the output release, with seconds Level seismic warning capabilities and minute intensity of intensity.
