Abstract
The geomagnetic transfer function for periods of variations duration from 5 to 8000 seconds and some quasi-1, 2 and 3D magnetotelluric inverse modeling has been calculated. For these calculations the data for the components of the magnetotelluric field vector, obtained both in the Bulgarian geomagnetic observatories Panagyurishte (PAG) & Plana (PLN) and during the magnetotelluric field survey on the entire territory, have been used. The transfer function over a long period of time and the results of the various kind of inverse modeling have been compared with the regional seismic activity and a correlation has been found between them. This shows that the geomagnetic transfer function could be used to predict the regional seismic activity in the central part of the Balkans.
