摘　　要：2016年11月4日,山西昔阳县发生M3.0地震,对地震前后昔阳台SSQ-2I石英水平摆倾斜仪的数据变化,使用原始曲线法、三点线性滤波及频谱分析等方法进行分析研究。结果表明,震前水平摆数据存在临震异常,其反映的前兆异常信息可尝试应用于今后的短临跟踪工作中。On November 4,2016,an earthquake with M 3.0 occurred in Xiyang County of Shanxi Province.The data changes of the SSQ-2I quartz horizontal pendulum tiltmeter around the earthquake were analyzed by using the original curve method,three-point linear filtering and spectrum analysis.The results show that there is an impending earthquake anomaly in the horizontal pendulum recordings before the earthquake,and the precursor anomaly information reflected can be applied to the short-term tracking work in the future.
