Regional tectonic setting of the Marmara Sea. a Blue line is the North Anatolian fault (NAF) and black lines are other plate boundaries (Bird 2003). The slip rate of the NAF is that of Reilinger et al. (2006). The three focal mechanisms shown are from the global CMT catalogue (Dziewonski et al., 1981; Ekström et al., 2012). Epicenters of earthquakes occurred between 1990 and 2014 (M _w  > 6) from the United States Geological Survey catalogue are shown by yellow stars. b Location and year of occurrence of past large earthquakes along the NAF
