Özet

The submerged portions of the North-Anatolian Fault (NAF) in the Sea of Marmara and the NE-Aegean Sea are sites of large magnitude earthquakes, that leave diagnostic geological "signatures" in the sedimentary record in the form of mass-wasting deposits, turbidites, and fluid and gas escape features. This is due to the interplay of seismic-shaking, mass- and turbidity flows, sediment resuspension and fluids circulation in relatively small subbasins with a complex paleo-oceanography, steep slopes, high rates of deformation, and diffuse fault-controlled gas and fluid seeps. To unravel the complex interrelations of these phenomena during earthquake cycles, we carried out paleoseismological studies at several key locations.
