Short summary
Deciphering coseismic offsets from creeping is a key point for an active fault behavior. In a subaqueous setting, coseismic offsets of the seafloor may be sealed off by earthquake-triggered sediments. Along the limit of a pull-apart basin in the Sea of Marmara, successive vertical offsets (up to 1.4m) are deduced from the thicknesses of homogenites which seal-off created scarps. During a 2kyr period, coseismic seafloor offsets are dominant, representing potential tsunami hazards.
