| Abstract: | This work addresses the experimental study of an important aspect in the general problem of lithosphere-magnetosphere coupling, namely the correlation between the Pc1 electromagnetic waves (0.2–5 Hz) and the earthquakes. Using long time series of measurements from the catalogues of Pc1 and earthquakes, we revealed a new effect: the diurnal Pc1 activity in the middle latitudes is statistically higher the lower the diurnal global seismic activity. We assume that the influence of earthquake-related acoustic waves on the upper atmosphere suppresses the activity of the Pc1 waves. |
