Analysis of deformation interference at Baotou Seismic Station
摘要
Abstract
According to the analysis of the observations of extensometer, water tube tiltmeter and horizontal pendulum tiltmeter, it is found that wind disturbance, lightning, rainfall, temperature and pressure, calibration and earthquake, instrument failure and power failure are the main factors that affect the observation of three instruments at Baotou Seismic Station. The characteristics of interference are missing, data jump, sharp pulse, high frequency interference, step, glitch, significant change, rough curve, trend changes and so on. Different types of observation instruments have different responses to interference, the identification and elimination of the interference is conducive to the application of seismic observation data and the analysis of seismic anomaly.关键词
