In 1981 and 1982 intensive observations of the geomagnetic field were carried out in a possible seismic gap region in the western part of the North Anatolian Fault Zone to trace on active fault and also to accumulate geomagnetic data for earthquake prediction research. The data of magnetic anomalies obtained from profile measurements across the fault were interpreted to reveal an anomalous magnetic structure associated with the active fault. In order to confirm our results thus derived in the Iznik-Mekece area, similar observations were also made at IsmetpaSa where fault traces are well known as well as creep for the North Anatolian Fault Zone.It is concluded that highly magnetized dike-like bodies exist extensively along active fault lines in the North Anatolian Fault Zone. This characteristic feature can be utilized for studies of active fault location and also for tectonomagnetic studies.
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 Dokurcun (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
A method is offered for computing families of curves for interpretation of total, veitical and horizontal magnetic anomalies produced by twodimensional bodies of arbitrary shapes.
