| Zusammenfassung |
| The model of the generation of small-scale current systems (and local strong electric
fields) in the atmosphere a few days before earthquakes - and possibly also during a
few days after the event - proposed some years ago is further developed. In the
model, the existence of clouds of dusty plasmas consisting of aerosols, ions and
electrons is suggested. An additional ionization of the clouds is connected with radon
emanation out of regions of the preparation of strong earthquakes. The related formation
of mosaic-like spatial distributions of charge separation, and the correspondingly
generated electric fields of 3Â 102 - 105 V/m, as well as rather large atmospheric areas of
increased electrical conductivity are assumed to have physical consequences which
may be observed near the Earth’s surface, in the atmosphere, and in the ionosphere
using optical and radiophysical methods. In the work, new results of the analysis of
such possible consequences are presented. Amongst others, spectra of infrared
emissions are studied, especially spectral intervals of carbon dioxide emissions with
centres at 4.3, 4.2, 9.4, 10.4, and 15.0 μm. Links between investigated electrical
disturbances in the atmosphere and ionospheric disturbances which may be observed by
vertical sounding experiments are examined. Instabilities in current systems and the
turbulization of charged clouds are analysed. The possible investigation of the described
phenomena using radio-location techniques is discussed. Thus, it is proposed to search for
additional radio-locational interferences in the atmosphere in seismo-active regions. |
