a Bathymetry from the MCS data. Faults interpreted on the MCS profiles are overlain by solid and broken red lines. Here, the fault segments, where no clear displacement at the seafloor can be observed, are delineated by broken lines. Three red circles mark the location of the EWFs on lines 10, 14, and 16. b Time slice at the two-way travel time of 140 ms with fault strikes. The faults were mapped where reflection amplitudes rapidly changed laterally. c Q slice at the two-way travel time of 220 ms with fault strikes. The faults are mapped along zones of high attenuation (red-to-yellow colors). d Map view of average velocities of the water column estimated by velocity analysis of the MCS data. The NMO velocities from the velocity analysis (Fig. 7 and Additional file 8) have been corrected by using Levin (1971) equation to remove the effect of dipping seafloor
