Abstract
A discrete spectrum of seismic oscillations was obtained in the range of pe riods 1-2 h. These oscillations were recorded in St. Petersburg (60 degrees N, 30 degrees E) by a seismometer with a vertical pendulum. The frequency distances between the harmonics of this spectrum are in agreement with the theory of short-period free oscillations of the atmosphere of the Lamb-wave type.
