- Abstract
The vertical component of the electric field strength and atmospheric current variations accompanying strong earthquakes with a magnitude of more than six are analyzed on the basis of instrumental observations carried out at the Mikhnevo Geophysical Observatory and at the Center for Geophysical Monitoring in Moscow (Sadovsky Institute of Geosphere Dynamics, Russian Academy of Sciences). It is shown that the strong earthquakes cause alternating sign–time variations of the electric field or its baylike variations of positive or negative sign at significant distances from the earthquake source. In the same time, earthquakes cause variations in the atmospheric current in the form of an increase in it or alternating sign–time variations of the averaged amplitude. The present results supplement the corresponding database and may be of interest in improving the known and developing new models of the effect of earthquakes on the environment and their verification.
