| Zusammenfassung |
| It is well known that lithospheric electromagnetic emissions are generated before earthquakes
occurrence. In our study we investigate the physical penetration mechanism of a pre-seismic
electric field from the Earth’s surface into the ionosphere. A simplified approach is
determined by using the electro conductivity equation, i.e. -(ËÏ- -
Φ) = 0, in the case of a
vertical inclination of the geomagnetic field lines. In our model the three dimensional
behaviour of the problem with a finite earthquake preparation zone in both directions is
investigated. Particular interest is given to the vertical profile of the electric conductivity from
the Earth’s surface up to the topside of ionospheric F-layer. Our results are discussed
and compared to the models of Pulinets et al. (1998) and Grimalsky et al. (2003). |
