Seismic sections of the Kerama gap. a Submarine topography of the Kerama gap. This map was prepared using Generic Mapping Tools (Wessel et al. 2019). Elevation and depth data are from SRTM15+V2.4 (https://doi.org/10.1029/2019EA000658; accessed 1 Dec 2021). b and c Seismic sections along lines 1020 and 1012, respectively. Note that the Ryukyu Group equivalent increases its thickness from the basin side toward the fault scarp along the northeastern margin of the OMSP (arrowed). A, Shimajiri Group equivalent; B, Ryukyu Group equivalent; C, Sediment younger than the Ryukyu Group; Bs, Acoustic basement
