Anatolian plate active faults character using potential fields data

Abstract

The paper investigates the features of the manifestation in potential fields methods (gravity and magnetic exploration) of faults in the territory of modern Turkey and their relationship with earthquakes. The relevance of the work is determined by the significance of studying active faults as seismogenerating structures that directly affect the degree of seismic hazard of the territory of Turkey. The purpose of the work: based on geophysical and geodynamic data, to study the active faults of modern Turkey and adjacent territories, trace them to a depth and compare them with the foci of earthquakes that occurred in Turkey, including in February 2023. The study used original methods of data interpretation potential fields methods: complex analysis of maps of gravimetric and magnetic fields, tracing of lineaments, construction of transformation maps, solving the inverse problem using “tomography of potential fields” technology. For the entire selected territory, the inverse problem was solved for gravity and magnetic exploration data using the “tomography of potential fields” technique. A great potential has been identified in the data of gravity and magnetic exploration for the assessment of inhomogeneities in the structure of the Earth’s crust.
