Abstract The varying characters of observations and disturbances of the cross fault short leveling, short baseline and MD fault creep testing apparatus at Anqiu seismic station are deseribed,and the relationship of above three methods using correlation analysis method is discussed. The results show that: the short leveling observations are affected by temperature and ground water level, and the observations are negatively correlated to temperature, positively correlated with ground water level. There is a obvious correlation between baseline and temperature, the related coefficient is about 0.95. The level orthogonal, skew and vertical direction observation of MD fault creep testing apparatus are all affected by temperature. In long time, there is a good correlation between the level orthogonal, skew observations and temperature, and the related coefficient is 0.98 and 0.99 respectively, but the correlations are more complex in short time, the changes of observed deformation are ahead of temperature changes. The vertical observations are different correlated with temperature in different seasons. There is a good coherence between short baseline and MD fault level orthogonal observation, we can do some comparative observations in suitable fields. And the short leveling and MD vertical direction observation have no obvious coherence. The above two observation methods are unfit to observe simultaneously when the MD apparatus is installed in semibasement.
