my country has built the world's largest real-time earthquake observation network

News from this site on May 12. According to Science and Technology Daily, May 12 is my country’s 16th National Disaster Prevention and Reduction Day. From the first National Earthquake Prevention and Disaster Reduction Science Popularization Home Event, we learned that the national earthquake intensity The rapid reporting and early warning project has been completed, and my country has built the world's largest real-time earthquake observation network. At the home event of earthquake prevention and disaster reduction science popularization, experts introduced the construction and operation of my country's earthquake monitoring network. my country's earthquake monitoring network is led by the State Seismological Administration and has formed a complete earthquake monitoring system, including earthquake observation stations, earthquake monitoring centers, earthquake rapid reports and early warnings, etc. At present, the country has

Researcher at the Institute of Engineering Mechanics of the China Earthquake Administration and National Earthquake Intensity Rapid Forecast and Early Warning Ma Qiang, chief engineer of the project, said that the system can provide valuable time from a few seconds to tens of seconds before the destructive seismic waves arrive, allowing people to take avoidance measures and reduce casualties. In addition, critical infrastructure such as high-speed trains, gas pipelines and nuclear reactors can take timely emergency measures to prevent secondary disasters.

In order to achieve effective earthquake early warning, not only a dense earthquake observation network and a reliable automated processing system are needed, but also a low-latency communication network and a multi-channel emergency information release system.

my country’s earthquake intensity rapid reporting and early warning project has been completed by the end of 2023 and has become operational. This project enables the formation of second-level earthquake early warning capabilities in key areas of my country and the formation of minute-level earthquake intensity rapid reporting capabilities across the country. After the completion of the project, relying on television, radio, Internet, new media, information receiving terminals and other publishing platforms, it will provide earthquake early warning, earthquake parameter quick report, earthquake intensity speed report for various users such as governments at all levels, the public, primary and secondary schools, industry enterprises, etc. product information services such as reports and earthquake parameter quick reports.

This site noticed that Ma Qiang also emphasized the limitations of the earthquake early warning system, pointing out that it is not suitable for all earthquakes and all affected areas. Technical blind spots in warning, short warning time in severely damaged areas, and second-level calculation of warning time are all its limitations. He reminded that earthquake early warning is only a means to reduce earthquake disasters, and multiple measures need to be taken. Ma Qiang called on the public to understand earthquake disasters scientifically and effectively use early warning information to maximize the disaster reduction benefits of early warning systems.
