-
摘要: 2022年5月2日07时53分,山东潍坊市青州市(东经118.27°,北纬36.55°)发生3.4级地震,震源深度8 km。地震发生后,潍坊地震监测中心站(以下简称潍坊中心站)迅速响应,立即组织力量开展震情分析研判、现场流动监测、灾情调查与烈度评定、应急宣传等工作,充分发挥了省局地震工作先遣队作用。本文从潍坊中心站现状及观测仪器布设、地震应急服务响应情况、震后思考与建议等三个方面就青州地震应急工作进行探讨,分享应对地震突发事件采取的具体措施,为其他地震台站高效处置突发地震提供经验积累和科学参考,具有一定的实践意义。Abstract: At 07:53 on May 2, 2022, a magnitude 3.4 earthquake occurred in Qingzhou City, Weifang City, Shandong Province (118.27°E, 36.55°N), with a focal depth of 8 km. After the earthquake, the Weifang Earthquake Monitoring Center Station (hereinafter referred to as the Weifang Central Station) responded quickly and immediately organized forces to carry out earthquake situation analysis and judgment, on-site mobile monitoring, disaster investigation and intensity assessment, emergency publicity and other work, giving full play to the role of the provincial bureau's earthquake work vanguard. This paper discusses the emergency work of Qingzhou earthquake from three aspects: the current situation of Weifang Central Station and the layout of observation instruments, the response of earthquake emergency service, and the post-earthquake thinking and suggestions, and shares the specific measures taken to deal with the earthquake emergency, providing experience accumulation and scientific reference for other brother stations to effectively deal with the sudden earthquake, which has certain practical significance.
