Comparison of the diurnal periodicity features of seismic noise,earthquakes, and electric power consumption

The main features of periodic changes in the parameters of seismic noise, seismicity and electric power consumption in industrial networks are compared to verify the hypothesis on the technogenic influence of electric network load on seismic noise and seismicity and to search for possible origins of the diurnal periodicity in seismic emission processes discovered in various regions of the world. Sufficiently good similarity of the compared processes is revealed that does not contradict the hypothesis. However, there are also some important discrepancies. An inverse phase pattern of interdiurnal distributions of weak and strong Japanese earthquakes has been found, and various possible mechanisms of this phenomenon, which had been observed earlier in certain other regions, are discussed.
