摘　　要：地震预警基于实时地震学的理论和方法。地震预警的目的是减少人员伤亡和重大工程设施的应急。对中小地震发布地震预警是不合适的。探讨地震预警可能存在的风险及风险控制问题。就有效地震预警区、预警时间、预警阈值、预警风险、风险防控对策等问题进行了探讨。Earthquake early warning is based on theory and method of real-time seismology,which aim for reducing casualties and meeting an emergency of critical project. It is inappropriate to release early warning for moderate and small earthquake. In this paper,the writers discussed the possible risk of earthquake early warning and risk control. It focused on the area,time,threshold,risk of effective earthquake early warning and risk control strategies.
