On the basis of the data on perturbations in the Earth's atmosphere recorded before and after 52 significant earthquakes that occurred during the period from 1997 to 2018 in the Asian region, it is shown that the amplitudes of internal gravity waves that originated from seismically active regions can be used at the saturation threshold level for a short-term indication of upcoming seismic events.

Based on the data of experimental studies of wave disturbances in the Earth's atmosphere before and after the earthquakes in Uzbekistan (May 26, 2013) and Kyrgyzstan (January 8, 2007), earlier unknown changes in the parameters of internal gravity waves are revealed. These changes were manifested during the period of five days before the earthquake and in certain cases can be used for short-term prediction of the time when seismic events are to occur.
