摘要
在中国现有基础上,通过分析地震预警盲区与震级下限,得出影响地震预警效能的关键因素,然后对地震预警的局限与争议进行讨论;结合现地预警和异地预警,确定中国地震预警建设的重点区域,并以此为基础,分析地震预警系统架构设计的关键——信息发布系统与保障系统的设计;对预警系统的社会风险进行阐述。总体来说,对于中国地震预警系统的未来,只有充分认识到其中蕴涵的风险与机遇,用客观、科学的态度对待每一项问题,提前做好不同的预案,合理地调配各种资源,才能建成具有社会效益的地震预警系统。
Based on national conditions and by analyzing earthquake early warning blind area and magnitude lower limit, this paper concludes the key factors affecting earthquake early warning efficiency, and then discusses the limitations and controversies of earthquake early warning. By combining on-site and regional warning, this paper confirms the key area of China's earthquake early warning construction; and on this basis, analyzes the key of earthquake early warning system architecture design: information release and guarantee system design; and also expounds the social risks of early warning system. In general, for the future of earthquake early warning system in China, only when fully realize the risks and opportunities, use objective and scientific attitude toward each problem, make different plans in advance, allocate resources reasonably, can we establish the earthquake early warning system with social benefits.
