Block Kinematics, Interseismic Coupling and Fault Slip Rates in the Aegean Region From GPS and Earthquake Slip Vector Data: 1. Upper Plate Structures

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract We represent the active deformation of the Aegean region with an elastic‐kinematic block model composed of a finite number of rotating crustal blocks whose boundaries coincide with major active structures. A total of 832 GPS velocities and 146 earthquake slip vectors were inverted to provide estimates of block rotations and interseismic ...

New Constraints on Active Normal Faulting in the South Gulf of Evia, Greece: Geometry, Evolution, and Seismic Hazard of the South Coastal Fault System

Tectonics, Volume 45, Issue 7, July 2026.
Abstract In many areas of active faulting, the continuity of normal faults with short or incomplete historical earthquake records and more subdued topographic expressions is not fully understood and consequently the seismic potential of these faults is often underestimated.
