我国成功建成全球规模最大的地震预警网络，这标志着我国在地震预警技术领域的重大突破和领先全球的地位。这一网络的建成，不仅显著提升了我国在地震预警能力上的全球影响力，也为公众、政府、行业和社会提供了更为及时、准确的地震信息，为减灾防灾、保护生命财产安全、提高应急响应效率提供了坚实的技术支撑。
国家地震预警工程，自2018年启动建设以来，经过不懈努力，最终于2024年7月25日顺利通过竣工验收。工程覆盖了华北、东南沿海、南北地震带、新疆天山中段、西藏拉萨周边等5个重点预警区域，构建了全球规模最大的地震预警网络。这一网络的构建，不仅在秒级时间内实现了对重点预警区域的地震预警能力，而且在全国范围内实现了分钟级的烈度速报能力，为防灾减灾工作提供了强有力的科技保障。
国家地震预警工程的成功实施，不仅体现了我国在地震预警技术领域的自主创新能力，更是对全球地震预警技术发展的重大贡献。项目总工程师马强表示，地震预警与地震预报有着本质的区别。地震预警是在地震发生后，利用地震波速度差的原理，快速捕捉到“纵波”的信号，通过计算和处理，预测出地震的震级、烈度、震源深度等关键信息，从而提前向公众发出预警信息。而地震预报则是对未来地震发生的可能性进行预测，需要基于长期的地震活动监测、地质结构分析等复杂数据和模型。
国家地震预警工程的成功，得益于其构建的高速集成的复杂系统，包括33个预警中心、近2万个不同类型的监测站点和自主研发的自动化处理系统。这一系统能够迅速捕捉地震信息，精确计算地震参数，并通过专用终端、广播、电视、微信等媒体渠道，向亿级用户提供秒级覆盖的快速服务能力。此外，项目还通过定制化服务，在铁路、管网、电网、核电、燃气等行业完成了地震预警信息的应用示范，进一步提升了地震预警技术的社会应用价值。
这一全球规模最大的地震预警网络的建成，不仅对我国的地震预警能力进行了全面提升，也为全球地震预警技术的发展树立了新的标杆。它不仅为公众提供了更加及时、准确的地震预警信息，还为政府、行业和社会提供了有力的决策支持和应急响应能力，为减少地震灾害损失、保护人民生命财产安全作出了重要贡献。

News Title: “China Launches the World’s Largest Earthquake Warning Network: A Breakthrough in Innovation”
Keywords: Earthquake Warning Network, Global Scale, Technological Innovation
Content: China has successfully established the world’s largest earthquake warning network, marking a significant breakthrough and global leadership in earthquake warning technology. This network has notably enhanced China’s global influence in earthquake warning capabilities, providing the public, government, industries, and society with timely and accurate earthquake information. It has provided solid technical support for disaster reduction, protection of life and property, and improvement of emergency response efficiency.
The National Earthquake Warning Project, launched in 2018, was completed with relentless efforts and successfully underwent竣工验收 on July 25, 2024. The project covers five key warning areas: North China, the southeast coast, the north-south seismic belt, the Tianshan region in Xinjiang, and the Lhasa area in Tibet. It has built the world’s largest earthquake warning network. This network not only provides earthquake warning capabilities in seconds for key warning areas, but also offers minute-level烈度速报能力 across the country. It provides strong technological safeguards for disaster prevention and mitigation work.
The successful implementation of the National Earthquake Warning Project not only showcases China’s autonomous innovation capability in earthquake warning technology but also makes a significant contribution to the development of global earthquake warning technology. Project Chief Engineer Ma Qiang explains that earthquake warning is fundamentally different from earthquake prediction. Earthquake warning uses the principle of the difference in velocity between P-waves and S-waves to quickly capture the signal of P-waves. Through calculations and processing, it predicts the earthquake magnitude, intensity, and source depth, and issues timely warning information to the public. In contrast, earthquake prediction attempts to forecast the possibility of future earthquakes based on long-term monitoring of seismic activity, geological structure analysis, and complex data and models.
The success of the National Earthquake Warning Project is owed to its construction of a high-speed integrated complex system, including 33 warning centers, nearly 20,000 different types of monitoring stations, and an independently developed automated processing system. This system can swiftly capture earthquake information, accurately calculate earthquake parameters, and provide quick service capabilities through dedicated terminals, broadcasting, television, WeChat, and other media channels to hundreds of millions of users. Additionally, the project demonstrated the application of earthquake warning information in industries such as railways, pipelines, power grids, nuclear power, and gas, further enhancing the social application value of earthquake warning technology.
The establishment of this world’s largest earthquake warning network has not only significantly upgraded China’s earthquake warning capabilities but also set a new benchmark for the development of global earthquake warning technology. It not only provides the public with more timely and accurate earthquake warning information but also provides strong decision-making support and emergency response capabilities for the government, industries, and society. It has made significant contributions to reducing earthquake disaster losses and protecting the safety of people’s lives and properties.
