Abstract
. Earthquake-induced submarine slope destabilization is known to cause mass wasting and turbidity currents, but the hydrodynamic processes associated with these events remain poorly understood. Instrumental records are rare, and this notably limits our ability to interpret marine paleoseismological sedimentary records. An instrumented frame comprising a pressure recorder and a Doppler recording current meter deployed at the seafloor in the Sea of Marmara Central Basin recorded the consequences of a Mwâ5.8 earthquake occurring on 26 September 2019 and of a Mwâ4.7 foreshock 2âd before. The smaller event caused sediment resuspension and weak current (
