整理鹤岗地震台多年形变观测资料,分析观测数据中较为明显的突跳、台阶等数据畸变出现的原因,结合观测环境、仪器故障、人为因素、同震阶跃等影响因素,讨论数据畸变特征,使地震台站人员在日常形变资料分析处理中,能够快速识别数据异常原因,为分析地震前兆异常数据提供参考。
Using the deformation observation data of Hegang Seismic Station for many years, the causes of some data distortion, such as more significant bust hop and step, are analyzed. Combining with observation four factors:environment, equipment failure, human factors, co-seismic step jump four factors, data distortion are discussed. This study provides a reference for the analysis of daily deformation observation data to quickly identify the reasons of data distortion and distinguish precursory anomalies.
