The data used in this study are multi-channel seismic reflection data collected on offshore Bababurnu which is located in the northwest shores of Edremit Gulf. Four seismic lines, BAB-001, BAB-002, BAB-003 and BAB-004 were collected by MTA Sismik-1 r/v and were processed and interpreted at İstanbul Technical University. The aim of the study is to investigate continuity and orientation of the faults in the sea, which are located in the southern branch of the North Anatolian Fault and border the Edremit Gulf from the North based on earlier geological research and to understand their relations with recently occurred Ayvacık-Çanakkale earthquakes between 14 January and 28 February 2017. The geology of the region consists of Pre-Tersiyer main formation, Kü.ükkuyu formation, granitic plutons, Ayvacık volcanic community, Bayramiç formation with basalt lavas and sedimentary fill of Edremit graben. The main faults observed in the region are the southern branch of the North Anatolian Fault with E-Wand NE-SW extending right lateral strike slip (Yılmaz and Karacık, 2001). Seismic reflection data must be processed by means of digital signal analysis before interpretation. For this purpose, the data must be passed through processing steps. These data processing steps are; eliminating the undesired traces in the dataset, definition of shotreceiver geometry, application of the frequency filters, application of gain recovery, sorting shots into common-depth-point (CDP) gathers, velocity analysis and NMO correction, removing multiple reflections, stacking and automatic amplitude gain application. Finally, migration process was applied to the stack sections both in time and depth domain.
