Özet

Since 1985, magnetic measurements have been conducted between Dokurcun and Abant pilot area of Turkish-German Earthquake Research Project which is located on the western part of the North Anatolian Fault Zone. A total of 28 magnetic observation stations have been established as repeated measurements points, including a base station in Cakillar. In this study, the time differentials were obtained from the measurements taken during the time periods of April-October 1985, June-October 1986 and June 1987. When the local field variations between the successive periods were compared it is clearly seen that the intensity of the anomaly around the Dokurcum (DOK) decreased from +20 nT to -2 nT. These changes could be related with the earthquake of magnitude 2.2 (June, 1985) occurred north of Dokurcun. The other anomalies were also changed related with the epicenter distribution which are moved toward to the west from April 1985 to June 1987.
