Low-frequency emissions and related phenomena in the ionosphere above the lithosphere deep faults inferred from satellite data

摘要

The comparative analysis of the variations of the low-frequency emission (0.1-20 kHz) intensity, low-energy electron fluxes and the plasma temperature at satellite altitudes (on 10 orbits of the "Intercosmos 19" satellite) above the lithosphere deep faults of the Norwegian Sea, the Baltic Shield, the Barents-Kara shelf and the West-Sibirian Lowland has been carried out. All these regions represent consistent changes in the Earth crustal structure and its geodynamic characteristics in the zone of transition from the Euroasian continent to the Arctic Ocean. The tectonic structures of these regions have different physical parameters and seismic activity. It has been detected that a special character of the low-frequency electromagnetic emission characterises each type of the lithosphere structure. (C) 2006 Elsevier Ltd. All rights reserved.
