In Turkey, studies on the tectonomagnetic effect have started at the end of 1970. Taking simultaneous measurements of the total geomagnetic field at a few stations in NW Turkey by proton precession magnetometers, some tectonomagnetic effects up to 50 nT accompanying felt earthquakes are observed within the period December 1972-March 1975. A linear relation is obtained between the magnitude and distance of the earthquakes which are close to the magnetic stations (less than 75km), and the observed tectonomagnetic effect.
Temporary magnetic measurements along a profile show that the tectonomagnetic effect increases towards the fault.
The last part of this study shows that it will be useful and possible to use the magnetic records of the Istanbul-Kandilli, Panagyurishte and Surlari observatories to compute tectonomagnetic effects of the past.
