Earthquake directions in Marmara-Istanbul region

Caption

Overview of the Marmara region, with the urban area of the Istanbul metropolis (red contour) and the Main Marmara Fault (red line). The orange circles represent the earthquakes for which directivity was estimated, with CL 1-4 indicating clusters of earthquakes. The black arrows represent the preferred rupture orientation. Closer analysis shows that the most repetitive orientation of rupture propagation is 85°N, hence towards Istanbul.
