PDR and continuous seismic profiling surveys in the Sporadhes basin (the western part of the North Aegean sea trough) reveal active gravity-induced deformation of the postorogenic sedimentary sequence. Different deformational patterns in the uppermost sedimentary layers of the flanks and floor of the basin suggest that the layers are deformed by several gravity-induced processes including slumping, sliding and creep contemporaneous with sediment deposition.
Antithetic faulting on the northern flank of the basin (the Thermaicos slope) results from downslope creep of surface layers over deeper tilted bedding planes. This process is a consequence of progressive slope development associated with the evolution of the Sporadhes basin. The morphology of the sea floor and the deformation of the upper layers clearly reflect synsedimentary tectonics in a subsiding basin environment.
