Abstract This paper takes extensometer and horizontal pendulum data in Yushugou as dependent variables and meteorological factors as independent variables to do correlation and regression analysis. The best regression equation is confirmed according to regression testing and comparing the various factors. Through the analysis of the regression residuals, the paper summarizes typical earthquake examples. Our research supports the following results: 1) Earth temperature is the main impact factor in the annual change of Yushugou fixed deformation (except pipe tilt meter NS) showing a quasi-linear relationship; 2) The air temperature is the main impact factor in the annual change of Yushugou pipe tilt meter NS, showing a quasi-linear relationship; 3) Two components of horizontal pendulum to observation data associated with geothermal show a highly negative linear relationship; 4) NE, EW of pipe tilt meter and three components of extensimeter show a highly positive correlation with the earth temperature; 5) NS of pipe tilt meter has a high positive correlation with air temperature and a negative correlationwith air pressure; 6) NE of extensimeter has positive correlation with earth temperature and air temperature; 7) Regression analysis can eliminate some influence of meteorological factors, helps us to recognize the seismic anomalies
