Seismological Bureau of China： The national earthquake intensity quick report and early warning project has completed the main construction task.

Cctv newsOn the morning of June 8, the State Council Office held a press conference on "Implementing the Party’s 20 Major Decisions and Deploying and Promoting the Modernization of Emergency Management System and Capacity". Min Yiren, director of the Seismological Bureau of China, introduced at the meeting that at present, the national earthquake intensity quick report and early warning project has completed the main construction task, and 15,391 earthquake early warning stations, 3 national centers, 31 provincial centers and 173 prefecture-level information release centers have been built, forming a China earthquake early warning network composed of five systems: station observation, data processing, information service, communication network and technical support, and carrying out pilot services in Beijing, Tianjin and Hebei, Sichuan, Yunnan and Fujian. It is expected to be completed and accepted by the end of this year. After the project is put into operation, it will play a role in disaster reduction in the following aspects:

The first is to build a "first line of defense" for earthquake relief and reduce earthquake casualties. After the devastating earthquake, China Earthquake Early Warning Network will release earthquake early warning information through various channels such as emergency broadcast, mobile phone, TV, special terminal, etc., so as to provide users in the target area with early warning time of several seconds to dozens of seconds for emergency avoidance; After the earthquake, the distribution of the hardest hit areas can be quickly judged by measuring the measured earthquake intensity in a few minutes, which provides a scientific basis for the decision-making and deployment of earthquake relief. 6.2 seconds after the Luding M6.8 earthquake in Sichuan Province on September 5, 2022, China Earthquake Early Warning Network successfully released the early warning information, realizing the second-level early warning coverage for 1.5 million people in the epicenter and its surrounding areas.

The second is to "escort" lifeline projects and emergency disposal of major infrastructure. Relying on earthquake early warning terminals, emergency broadcasting and special communication lines, we will provide earthquake early warning information for the automatic emergency response of major strategic infrastructure such as high-speed railways, nuclear power plants, oil and gas pipelines and Gaoba reservoirs, and people’s livelihood infrastructure such as high-rise buildings, underground facilities and large-scale complexes, fill the gap in cross-industry earthquake emergency response services, promote the expansion of earthquake monitoring to earthquake disaster risk monitoring and prevention, and strengthen the ability of earthquake prevention and disaster reduction in the whole society.

The third is to provide strong support for earth science progress and international disaster reduction cooperation. Give full play to the advantages of building the world’s largest real-time transmission earthquake monitoring station network, provide high-quality scientific data information for promoting the innovative development of real-time seismology, real-time disaster science and earthquake engineering, and help the development and progress of earth science. At present, China’s earthquake early warning technology has gone abroad and been applied to the construction of Indonesian Jakarta-Bandung High-speed Railway. Seismological Bureau of China will give full play to its professional and technical advantages, better serve the country’s overall diplomacy, strengthen international cooperation in earthquake prevention and disaster reduction, and work together to reduce the risk of earthquake disasters.

In the next step, Seismological Bureau of China will continue to improve the construction of earthquake early warning network in China, continuously improve the safety, reliability and standardization of earthquake early warning service, expand the service field and efficiency, and provide more powerful earthquake safety guarantee for high-quality economic and social development.
