简要回顾了地震预警的发展历程,介绍了地震预警的基本原理和地震位置、预警震级及预测烈度等关键参数的主要测定方法。作为一种能够有效减轻地震灾害的手段,世界上多个国家和地区相继开始建设各自的地震预警系统,以系统建设与应用实效为切入点,介绍了世界主要地震预警系统和我国的相关进展情况;并基于目前地震预警面临的主要挑战,从传感器、信号处理算法及组网模式等方面,展望了未来地震预警系统新的、有潜在变革性的技术和方法。
This paper briefly reviews the development process of earthquake early warning and introduces the basic principles of earthquake early warning as well as the main determination methods for key parameters such as earthquake location, early warning magnitude and predicted intensity. As an effective means to mitigate earthquake disasters, earthquake early warning systems have been set up in many countries and regions of the world. Taking the system construction and application effectiveness as the breakthrough point, this paper introduces the main earthquake early warning systems in the world and the related progress in China. And then, based on the main challenges faced by the earthquake early warning, new and potentially innovative technologies and methods for future earthquake early warning system are prospected from the aspects of sensors, signal processing algorithms and networking modes.
