Abstract To study the influence of the surrounding surface dynamic displacements caused by Madoi earthquake, using ultra long baseline modewe process 11 high rate GPS observations within 400 km of the epicenter and then analyze the time series of the horizontal displacements. The results indicate that the Madoi earthquake caused a displacement of about 25 cm at QHMD station on the eastward and did not recover to the preseismic status. On the northward, it caused about 27 cm at QHMQ and GSMA stations but recovered to preseismic status quickly. The influence of the earthquake on the dynamic displacements of the surrounding stations, especially on the northward displacement, has a high correlation with the relative azimuth of the stations to the epicenter.
