Based on the analysis of data from the Geophysical Observatory “Mikhnevo” and the Center for Geophysical Monitoring of Moscow of the Institute of Geosphere Dynamics of the Russian Academy of Sciences, the response of the atmospheric boundary layer to the strong earthquakes with magnitudes starting from ≥7 is considered. It is shown that the Tohoku earthquake (March 11, 2011, Japan) can be associated with the variations in atmospheric pressure with periods ranging from 8 to 11 h that emerged after this event, whereas a series of the strong earthquakes discussed in the work are accompanied by the variations in the atmospheric pressure with periods close to the singlets of the fundamental free oscillation of the Earth 0S2. Another effect after the earthquakes is the presence of the acoustic-gravity waves in the atmosphere with a period close to the Brunt-Väisäla period at large distances from the epicenter.
