Abstract

The study is devoted to the study of atmospheric, electromagnetic and ionospheric effects registered at a distance of about 2000 km from the earthquakes in Greece on May 24, 2014 and November 17, 2015 by the hardware complex of the geophysical observatory "Mikhnevo". One of the mechanisms that provide perturbations of geophysical fields at significant distances from the source is associated with the generation of acoustic waves caused by a surface seismic wave. When acoustic oscillations propagate to the atmosphere and ionosphere, they cause variations in the density of the neutral gas and the electron concentration in the ionosphere. In the D region, this leads to changes in the conductivity and modulation of horizontal ionospheric currents registered on the Earth's surface as variations of the geomagnetic field. The results obtained confirm the possibility of recording acoustic and electromagnetic effects at significant distances from the earthquake center.
