摘　　要：2023年1月30日新疆沙雅县(82.29°E,40.01°N)发生M_(S)6.1地震,震源深度50 km。地震发生前,中国局地震短临预报跟踪电磁学科组和新疆地震局电磁学科组依据中国地震局《地震电磁分析预测技术方法工作手册》、《新疆地区地震分析预测技术方法工作手册》和《地震电磁分析预报方法清单》对新疆地区电磁台站的数据进行异常梳理,发现新疆地区电磁台站存在流动地磁、地磁垂直强度极化、地磁逐日比、地磁低点位移等多项异常。震前异常综合预测意见与实发地震基本一致,震前中短期渐进式异常演化特征较突出,2017—2020年新疆地区地震电磁学科预测指标体系建设工作已初见成效。On January 30,2023,the M_(S)6.1 earthquake with focal depth of 50 km occurred in Xayar County(82.29°E,40.01°N),Xinjiang.Before the earthquake,the electromagnetic discipline group of short-term and imminent earthquake prediction tracking of China Earthquake Administration and the electromagnetic discipline group of Earthquake Agency of Xinjiang Uygur Autonomous Region sorted out the anomalies of the data of electromagnetic stations in Xinjiang according to Manual of Seismic Electromagnetic Analysis and Prediction Technical Methods,Manual of Seismic Analysis and Prediction Technical Methods in Xinjiang and List of Seismic Electromagnetic Analysis and Prediction Methods,and found that there were mobile geomagnetism multiple anomalies such as geomagnetic vertical intensity polarization,daily geomagnetic ratio,and geomagnetic low point displacement.The comprehensive prediction opinions of anomalies before earthquakes are basically consistent with the actual earthquakes.The evolution characteristics of medium and short-term progressive anomalies before earthquakes are prominent.The construction of the prediction index system of seismoelectromagnetic discipline in Xinjiang from 2017 to 2020 has achieved initial results.
