Abstract—In response to the kind invitation of the Editorial Board of the journal “Izvestiya, Physics of the Solid Earth” to take part in the discussion concerning the methodology of statistical study of correlations between geophysical processes, we have done a small research and written this paper. Being predominantly geomagnetologists, we focused on the topical question of a correlation between the earthquakes and geomagnetic storms and briefly touched upon the connection of the earthquakes with seismic noise. The main result of our analysis is as follows. The correlation between the earthquakes and magnetic storms exists objectively. The problem deserves a further study using statistical hypothesis testing methods, and a special attention should be paid to clearly distinguishing between causal and acausal correlations.
