Lateral variations in the signature of earthquake‐generated deposits in Lake Iznik, <scp>NW</scp> Turkey

Using lake-sediment cores to document past seismicity requires a comprehensive understanding of possible lateral variations in depositional processes. This study aims reveal the earthquake-induced event deposits throughout Lake Iznik, large lake located on middle strand North Anatolian Fault. Based stratigraphic, sedimentological and geochemical analyses 14 sediment from two subbasins across lake, five different types (T1-T5) were identified characterised. One deposit type (T5) is restricted delta mouth, characterised by occurrence authigenic Fe-Mn carbonates interpreted result flood events. The four other are their synchronicity between age consistency with historical earthquakes be likely generated earthquakes. locally prominent 1065 CE earthquake that ruptured sub-lacustrine Iznik Fault produced at least three deposits. (T2) only observed for this very local earthquake, implying might also depend ground-motion parameters. At scale, various depends flow distance source destabilisations coring site.
