Fig. 4From: Stress change generated by the 2019 İstanbul–Silivri earthquakes along the complex structure of the North Anatolian Fault in the Marmara Seaa Morphotectonic structure and fault system of the study area. NAFZ-C and NAFZ-D are C and D segments of the northern branch of the NAFZ, SF Silivri Fault, SRF Silivri Ridge Fault, SRSBF Silivri Ridge Southern Border Fault. b Dextral strike-slip system deformation model and directions of the active structures (Tchalenko 1970; Sylvester 1988). The colors in the model indicate the faults with the same characteristics as the fault on the map. c and d Interpreted and uninterpreted multichannel seismic reflection profile showing the main fault segments and secondary faults associated with the Silivri earthquakes (also see Additional file 1: Figure S3; profile adopted from Steckler et al. (2018)). The seismic reflection profile shown in this figure is displayed for up to 1.6 s (TWT), because when the entire profile is viewed for up to 5 s, the resolution of the profile reducesBack to article page
