地震预警服务进展及其国际比较

The Progress and International Comparison of Earthquake Early Warning Service

地震预警系统由预警技术系统和预警服务体系组成,是减少地震灾害造成人员伤亡和经济损失、增加社会稳定的一种有效方式,其中地震预警服务成为地震预警技术发挥作用的关键环节。该文基于地震预警服务的概念和基本内容,比较了全球主要的地震预警服务发展及应用情况,如中国、日本、墨西哥、美国等,综合分析了当前地震预警服务的不足,包括地震预警设备安装、信息内容、提示方式和科普教育,并提出了相应的对策建议。完善地震预警服务体系,有利于发挥地震预警作用,提高公众的应急避难能力,为提升我国地震预警服务能力提供一定的参考意义。

The earthquake early warning system consists of early warning technology system and early warning service system,which is an effective way of reducing casualties and economic losses caused by earthquake disasters and increasing social stability,and earthquake early warning service has become a key link in the function of earthquake early warning technology.Based on the concept and basic content of earthquake early warning service,the paper compares development and application of major earthquake early warning services worldwide,such as China,Japan,Mexico,USA,etc.,and comprehensively analyzes the disadvantages of earthquake early warning service,including the installation of earthquake early warning equipment,information content,hint method and popular science education,and puts forward corresponding strategies and suggestions.Improving the earthquake early warning service system is beneficial to exert the role of earthquake early warning and increase the public emergency shelter capacity,to provide some reference significance for the perfection of earthquake early warning service in China.
