在今天（7月26日）应急管理部中国地震局举行的新闻发布会上，一个里程碑式的消息被公布：国家地震预警工程于今年7月25日顺利通过竣工验收，正式全面建成。这一工程自2018年启动建设，历时数年，旨在通过构建全球规模最大的地震观测网络，提升我国地震预警能力和响应速度。
国家地震预警工程的建设成果显著，它不仅构建了覆盖全国的地震观测网，还成功完成了15899个观测站点的建设，以及在华北、东南沿海、南北地震带、新疆天山中段、西藏拉萨周边等5个重点预警区域形成了秒级地震预警能力。同时，在全国范围内，该系统还具备了分钟级烈度速报能力。这一系统在2022年四川泸定6.8级地震和2023年甘肃积石山6.2级地震中进行了实际检验，展现了其快速准确的预警能力，为政府抗震救灾、行业应急处置、公众紧急避险和地震科学研究提供了科学依据。
地震预警技术的核心在于利用地震波传播速度远小于电波传播速度的特点，通过密集的地震观测站网，在地震发生后迅速发出警报，为公众和重要设施提供宝贵的数秒至数十秒的预警时间。公众可以通过电视、广播、互联网、新媒体、信息接收终端等平台接收预警信息，而部分手机内置地震预警功能或下载地震预警App也成为了一种便捷的接收方式。
此外，为了进一步提升公众的地震预警接收体验，中国地震台网中心、中央广播电视总台国家应急广播与腾讯联合推出了“中国地震台网”全国微信预警服务，该服务预计近期上线。通过微信搜索“中国地震台网”地震预警小程序，完成授权并登记地理位置后，用户即可方便快捷地接收到官方权威的地震预警信息，这一举措将极大地增强公众的地震预警接收能力和响应效率。
国家地震预警工程的全面建成，标志着我国在地震预警领域的技术实力和应急响应能力达到了新的高度，为保护人民生命财产安全、减少地震灾害损失提供了坚实的技术保障。未来，随着技术的不断进步和应用的深入，这一系统将进一步优化和完善，为构建更加安全、智慧的地震预警体系奠定坚实基础。

At today’s (July 26) press conference organized by the Emergency Management Department and the China Earthquake Administration, a landmark announcement was made: the National Earthquake Warning Project successfully underwent竣工验收completion and officially became fully operational on July 25 of this year. This project, which began construction in 2018, has spanned several years, aiming to enhance China’s earthquake warning capabilities and response speeds through the establishment of the world’s largest earthquake observation network.
The construction of the National Earthquake Warning Project has yielded significant results, as it not only sets up a nationwide earthquake observation network but also successfully builds 15,899 observation sites, establishing sub-second earthquake warning capabilities in five key warning areas: the North China Plain, the southeastern coastal regions, the north-south earthquake zones, the Tian Shan region in Xinjiang, and the areas around Lhasa, Tibet. Additionally, the system offers minute-level intensity reporting capabilities across the country. The system’s capabilities were tested in actual scenarios during the 2022 Sichuan Ludian 6.8 magnitude earthquake and the 2023 Gansu Jisitang 6.2 magnitude earthquake, showcasing its rapid and accurate warning capabilities. This has provided scientific evidence for government disaster relief, industry emergency response, public emergency evacuation, and earthquake scientific research.
The core of earthquake warning technology lies in leveraging the fact that seismic waves travel much slower than electromagnetic waves. By deploying a dense network of earthquake observation stations, the system can quickly issue alerts after an earthquake occurs, providing the public and critical facilities with precious seconds to tens of seconds of warning time. The public can receive warning information through various platforms such as television, radio, the internet, new media, information reception terminals, and some mobile phones come equipped with earthquake warning functions or download earthquake warning apps for a convenient receiving method.
Furthermore, to further enhance the public’s earthquake warning receiving experience, the China Earthquake Network Center, the China National Emergency Broadcasting of the Central Radio and Television General Station, and Tencent have jointly launched a “China Earthquake Network” nationwide WeChat warning service, which is expected to be available soon. By searching for the “China Earthquake Network” earthquake warning mini-program on WeChat, users can conveniently and quickly receive official and authoritative earthquake warning information after granting authorization and registering their location. This initiative will significantly enhance the public’s ability to receive and respond to earthquake warnings.
The full completion of the National Earthquake Warning Project marks a new height in China’s technical capabilities and emergency response in the field of earthquake warning, providing solid technological guarantees for protecting people’s lives and property and minimizing earthquake losses. In the future, as technology continues to advance and its applications deepen, this system will further optimize and improve, laying a solid foundation for the establishment of a more secure and intelligent earthquake warning system.
