Abstract: We performed a search for a possible change of the horizontal component of the wind velocity at altitudes of 80–300 km over earthquake epicenters. We used the measurement data derived by the WINDII device set on the board of the UARS satellite from 24 December 1991 till 12 April 1994. We analysed 234 earthquakes with the magnitude more than 6. We tried to detect common tendencies for all earthquakes using the method of epoch superposition. In addition, we analysed a wind change over each earthquake by plotting wind maps for an altitude of 90 km. We noted wind growing at altitudes 81 –102 km and 135–250 km together with disturbance of the wind radial component relatively an earthquake epicenter at altitudes of 125–260 km which has a maximum one day before the earthquake. The generation and propagation of inner gravity waves can be considered as a possible mechanism of energy transfer from an earthquake into upper atmosphere.
