摘　　要：乌什7.1级地震是国家地震烈度速报与预警工程建成以来首个7级以上地震,为提高防范和减轻地震风险能力,切实将地震烈度速报与预警工程建设到位,将预警实时产出的震级、震中位置及震源深度结果与国家台网中心正式速报结果对比分析,并分析仪器烈度产出误差。结果表明国家预警网在震中严重偏网的情况下,仍能够展示出稳定、可靠、高效的地震预警和烈度速报能力。Wushi M_(S)7.1 earthquake is the first earthquake above M7 since the completion of the national earthquake intensity rapid report and early warning project.In order to improve the ability to prevent and mitigate earthquake risk,the construction of earthquake intensity rapid report and early warning project is put in place.The magnitude,epicentral location and focal depth results of the real-time output of early warning are compared with the official rapid report results of the National Network Center,and the instrument intensity output error is analyzed.The results show that the national early warning network can still demonstrate stable,reliable and efficient earthquake early warning and intensity rapid reporting capabilities in the case of severe epicenter deviation.
