Investigation of Potential Structures in the Southeastern Aegean Region Using Seismological and Gravity Data

Abstract

This study investigates potential structure distribution in the southeastern Aegean Region, a seismically active and complex region of the Eastern Mediterranean. Using gravity data from theTOPEX v29.1 database, the Fast Sigmoid (FSED) and Tilt Angle of the Horizontal Gradient (TAHG) methods were applied to detect potential structural boundaries. Earthquake and focal mechanism catalogs compiled from various databases were also used to interpret the identified structural edges. A total of 69 structure boundaries were detected, some of which are potential faults related to existing faults. The results of this study provide new insights into the region’s tectonic framework, revealing both the continuity of known faults and the identification of new potential faults, thus contributing valuable information on the region’s seismotectonic characteristics
