鹤岗地震台形变观测数据特征分析

Analysis on the interference of deformation observation data in Hegang seismic station

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.
